4 * Major overhaul of the perfdata code. This includes API breakage and
6 - Probes were not sorted correctly
7 - Voltage data was not included
8 * The PNP template check_openmanage.php has been redone to work with
9 the changes in perfdata output from the plugin
10 * A new option '--legacy-perfdata' will make the the plugin output the
11 performance data in the old format
12 * The old PNP template for performance data is available in the
13 distribution as 'check_openmanage_legacy.php'
14 * Added support for a configuration file
15 * Added manual page for the configuration file
16 * If using html output, URLs will now open in a new window
17 * Added a compatibility fix for OMSA 6.5.0, related to performance
18 data for amperage probes when the plugin is used in local
19 mode. Thanks to Benedikt Meyer for a patch.
24 * Added workaround for a rare condition in which blade detection fails
25 because the chassis IDs for the blade and interconnect board have
26 switched places in the BaseBoardType SNMP table.
31 * A regression wrt. non-certified drives were fixed. The plugin failed
32 to identify non-certified physical drives via SNMP.
33 * Added the ability to blacklist non-certified drives with the
34 'pdisk_cert' blacklisting keyword.
39 * Fixed typo in help output
40 * SD card check is now included if the parameter '--only chassis' is
42 * The plugin will issue a proper warning if a physical drive is
43 uncertified, instead of an unspecified warning. One or more
44 uncertified drives will make the controller go into a non-critical
46 * Slightly improved reporting of fan status
47 * Exit with value 3 (unknown) if printing debug, help or version
48 info. This is considered best practice for Nagios plugins.
49 * Workaround added for logical SAS connectors to external storage
50 enclosures, when using check_openmanage in local mode with OMSA
51 6.4.0 or later versions. The output from omreport could contain
52 lines that the plugin was unable to parse, which would lead to
58 * Fix counting of components when blacklisting is used. Components
59 should be counted even if blacklisted
60 * Added some unsupported vdisk types to the list. The OMSA MIB
61 identifies these, but lists them as unsupported.
62 * Added option '-B' or '--show-blacklist' to show any blacklistings in
64 * Fixed a bug for checking voltage probes, if the reading is missing
66 * Fixed a regression bug for a power monitoring corner case.
71 * Added more robustness wrt. values from OMSA obtained via SNMP, to
72 avoid internal errors where non-important values are missing.
77 * A few compatibility fixes for OMSA 6.4.0 were added.
82 * Added support for IPv6 when checking via SNMP. IPv6 can be turned on
83 with the option '-6' or '--ipv6'. The default is IPv4 if the option
85 * Added support for TCP when checking vis SNMP. The option '--tcp' can
86 be used to turn on TCP. The default transport protocol is UDP if the
87 option is not present.
88 * The mode of operation (local or SNMP) is shown in the debug
89 output. If SNMP is used, the debug output will also show the SNMP
90 protocol version, IP version and transport protocol (UDP or TCP).
91 * Amperage probe status via SNMP is of type "probe status", not
92 regular status. This has been fixed.
93 * Massive overall robustness improvements to handle OMSA bugs where
94 some information from OMSA is missing.
95 * Memory module enumeration via SNMP changed somewhat to reflect
96 enumeration provided by omreport. This ensures that the plugin's
97 output is identical in SNMP or local mode wrt. dimms IDs.
98 * Fan enumeration via SNMP changed somewhat to reflect enumeration
99 provided by omreport. This ensures that the plugin's output is
100 identical in SNMP or local mode wrt. fan IDs.
105 * Included new check for SD cards. Newer servers such as the R710 can
106 have SD cards installed, these should be monitored. The SD card
107 check is on by default. A new blacklisting keyword 'sd' has been
108 added. The SD card check can be turned off with '--check sdcard=0'.
109 * Handle special cases where power monitoring capability is disabled
110 due to non-redundant and/or non-instrumented power supplies.
111 * For physical disks probed via SNMP, check that values for vendor,
112 product ID and capacity is available before attempting to display
114 * If a physical disk is in sufficiently bad condition, the vendor
115 field reported by OMSA may be empty. The plugin now handles this
116 situation without throwing an internal error.
122 * Storage is no longer allowed to be absent. If the plugin doesn't
123 find a storage controller, it will give an alert. For diskless
124 systems or servers without a Dell controller that OMSA recognizes
125 you will now have to specify '--no-storage' or '--check storage=0'
127 * Report the system revision (if applicable) wherever the model name
128 is printed. E.g. "PowerEdge 2950 III" instead of "PowerEdge 2950".
129 * Small change in search path for omreport: The new location for OMSA
130 6.2.0 and later on Linux will be attempted first.
131 * Small bugfix for the '--check' parameter, if the argument is a
132 filename. The file could not contain a linebreak, this has been
134 * Added an option '--no-storage', which is equivalent to the general
135 option '--check storage=0'.
141 * If a physical disk is a hot spare, display this information in
143 * Report the bus protocol (e.g. SAS, SATA) and media type (e.g. HDD,
144 SDD) for physical disks in the debug output, if applicable
145 * Minor fix for 100GB physical disks, write "100GB" instead of "99GB"
146 * SNMP: Use new features of OMSA 6.3.0 to display occupied and total
147 slots in storage enclosures, if applicable. This information is not
148 available with omreport and check_openmanage will not display this
150 * SNMP: Added new processor IDs from the OMSA 6.3.0 MIBs
151 * SNMP: Use connection tables in a proper way to determine controller
152 and enclosure IDs, for use with physical disks and enclosure
153 components (fan, temp sensors etc.). This fixes a long standing bug
154 for servers with more than one controller, if checked via SNMP.
155 * SNMP: Use the nexus ID as last resort to find the controller for
156 physical disks. Workaround for older, broken OMSA versions.
157 * SNMP: Identify enclosures (e.g. '2:0:0') properly so that the
158 reporting with SNMP corresponds to the same report with omreport.
159 * SNMP: added a couple of workarounds for pre-historic OMSA versions
165 * More fine-grained reporting of temperature warnings for enclosure
167 * Max/min temperature limits for enclosure temp probes are reported in
169 * Report enclosure temperature probes that are "Inactive" as ok
170 * Don't try to print out the reading of enclosure temperature probes
171 if the reading doesn't exist or is not an integer
172 * Report enclosure EMMs that are "Not Installed" as ok, instead of
174 * Corrected typo in the PNP4Nagios template
180 * Remove reporting of which controller a logical drive is "attached"
181 to, since this information can't be reliably extracted via SNMP.
182 * Avoid collecting Lun ID via SNMP for virtual disks, we don't use it
183 * Report total memory and number of dimms in the ok output
184 * Difference in reporting if amperage probes have discrete readings
185 * Workaround for broken amperage probes
186 * Added workaround for bad temperature probes that yields no reading
188 * Get OMSA version via SNMP slightly more efficiently
194 * Added robustness for received SNMP values that are not defined in
195 the MIB. Instead of throwing a perl warning when this happens, the
196 plugin will not report the undefined value.
197 * Defined "Replacing" as a defined state for physical disks in SNMP
198 mode, even though this state is not defined in the MIB. It is
199 reported as such by omreport.
200 * Physical disk brand/model is now reported when the state of the disk
201 is "Rebuilding" or "Replacing".
202 * The state of a physical disk is reported in parentheses when
203 predictive failure is detected. It is useful to know if a disk is
204 online, offline, spare or even failed when predictive failure is
206 * Handling of physical disk predictive failure has been improved
208 * Refactoring of the perfdata code. In conformance with the plugin
209 development guidelines, the UOM (unit of measure) previously
210 reported in the perfdata output has been removed.
211 * The -p or --perfdata option now
212 takes an optional agrument 'minimal', which triggers shorter names
213 for the perfomance data labels. This shortens the output and is a
214 workaround for systems where the amount of output exceeds the 1024
216 * The PNP4Nagios template has been updated. Users of check_openmanage
217 and PNP4Nagios are advised to upgrade. This version of
218 check_openmanage needs the new template.
219 * Lots of other small improvements and updates.
225 * New option '--use-get_table' is added as a workaround for SNMPv3 on
226 Windows using net-snmp. This option will make check_openmanage use
227 the Net::SNMP function get_table() instead of get_entries() to
228 collect information via SNMP.
229 * Include a blacklisting option 'ctrl_pdisk' which takes the
230 controller number as argument. This blacklisting option only works
231 with omreport and is a workaround for broken disk firmwares that
232 contain illegal XML characters. These characters makes openmanage
233 barf and exit with an error. Patch from Bas Couwenberg.
234 * If the blacklisting keyword "all" is supplied for a component type,
235 that component type is not checked at all, i.e. the commands are
236 never executed. This will make check_openmanage execute faster if
237 blacklisting is heavily used.
238 * Option '--htmlinfo' now has a shorter equivalent '-I'
239 * The option '--short-state' now has a shorter equivalent '-S'
245 * Fixed an SNMP bug where the plugin didn't handle OID indexes that
246 were not sequential. Thanks to Gianluca Varenni for reporting.
247 * Fixed an SNMP bug when checking old hardware such as the PE 2650 and
248 PE 750. The controller id for physical drives were collected and
249 displayed incorrectly. This release uses an additional OID to fetch
250 this info, which would otherwise be unavailable. Thanks to Gianluca
251 Varenni for reporting this bug.
252 * Should use %snmp_probestatus, not %snmp_status when checking the
253 status of voltage probes. Thanks to Ken McKinlay for a patch.
254 * Fix when identifying blades via SNMP with very old OMSA
255 versions. Patch from Ken McKinlay.
256 * Better way of finding the ID of physical drives via SNMP
262 * Added support for storport driver version for controllers, only
263 applicable on servers running Windows. A new blacklisting keyword
264 for suppressing storport driver messages was added.
265 * The "all" keyword in blacklisting is now case insensitive.
266 * More fine-grained reporting in the rare case where a controller
267 battery fails during learning and charging states.
268 * New improved way of reporting perl warnings during execution of the
275 * Fix for path to omreport on Linux with OMSA 6.2.0
276 * A couple of other small fixes
282 * Fix for undefined device name for logical drives (thanks to Pontus
284 * Fixed a bug in the PNP4Nagios template, that prevented the template
285 from working with PNP4Nagios 0.6. Thanks to the PNP4Nagios team for
292 * CPU type, family etc. are now reported in case of a CPU failure (and
294 * The debug output now reports Openmanage version and plugin version
300 * New option '-a' or '--all' turns on checking of everything
301 * The manual page (POD info) is removed from the script and is now in
302 a separate file, to make check_openmanage fully ePN compatible
303 * ePN is no longer disabled by default, check_openmanage no longer has
304 an opinion on whether it should run under ePN or not
305 * The '-m' or '--man' option is no longer available
306 * The option '-v' or '--verbose' is renamed to '-d' or '--debug',
307 which makes more sense wrt. its usage
308 * The '-g' or '--global' option is removed. Checking the global health
309 status is now default if applicable
310 * Checking intrusion detection is now turned on by default
311 * The obsolete option '--snmp' is removed
312 * The option '--state' now has a shorter equivalent '-s'
313 * The basename stuff and options '--only-critical' and
314 '--only-warning' are now replaced by an option '--only'
315 * If plugin is run by Nagios, redirect stderr to stdout
316 * Added option '--omreport', that lets the user specify the full path
317 to the omreport binary
318 * Added non-8bit-legacy default search paths for omreport.exe for
320 * Minor changes to the plugin output, for consistency
321 * New blacklisting keyword 'bat_charge' disables warning messages
322 related to controller cache battery charging. Thanks to Robert
323 Heinzmann for a patch.
324 * For blacklisting, the component ID kan now be "ALL", in which all
325 components of that type is blacklisted.
326 * Man page is moved to manual section 8
332 * Fixed a bug that could cause errors and weird results when checking
333 cooling devices (fans) via SNMP. Thanks to Ken McKinlay for spotting
334 this bug and reporting it.
339 * For failed physical drives, check_openmanage will now output the
340 drive's vendor, model and size in GB or TB.
345 * The -s|--snmp option was redundant and no longer does anything. SNMP
346 is triggered automatically if the -H|--hostname option is
347 present. The -s|--snmp option is kept for compatibility, but has no
353 * Added support for performance data (temperatures) from attached
354 storage enclosures such as the MD1000
359 * Fixed a regression in the --htmlinfo option when it is not supplied
365 * New option --htmlinfo adds clickable HTML links in the plugin's
371 * Fixed a regression bug in CPU and power supply reporting that only
372 affects verbose output
373 * If blacklisting is used, the global health check (via the --global
374 option) is now negated. Checking the global health doesn't make
375 sense when one or more components is blacklisted. Thanks to Rene
376 Beaulieu for reporting this bug
377 * The PNP4Nagios template is now included in the tarball and zip
383 * Improved memory error reporting, when using omreport
384 * Collect performance data from pwrmonitoring (amperage probes) that
385 were previously ignored when using omreport
390 * Improved memory error reporting, when using SNMP
391 * Other small ehnancements
396 * The plugin is now compatible with the Nagios embedded Perl
397 interpreter (ePN) in theory. However, the plugin will not not use
398 ePN by default. We don't want any "accidents".
399 * License is now GPLv3, previously only specified as "GPL"
400 * New options --only-critical and --only-warning. With these options
401 the plugin will only print critical or warning alerts, respectively.
402 * Bugfixes and speed enhancements in the storage section, when
403 checking enclosure components via omreport
404 * The --okinfo option is now less verbose and more to the point
405 * Lots of code refactoring for readability, maintainability and
411 * Fixed a bug in the storage section, when checking controllers. This
412 is an obscure bug that only manifests itself in the odd case where a
413 server has multiple controllers, and one of the controllers are
414 missing some of the OIDs, in which case these OIDs will be missing
415 for the other controllers as well. The change is minor and only
416 includes using get_table() instead of get_entries() to collect the
417 SNMP result. Thanks to Stephan Bovet for reporting this bug.
422 * The --perfdata option can now optionally take an argument
423 "multiline", which makes the plugin produce multiline performance
424 data output in a Nagios 3.x way. Not really needed, but the plugin
426 * Added comment within the 10 first lines to disable the nagios
427 embedded perl (ePN) interpreter by default for Nagios 3.x
428 * Improvements in the performance data output. Units are now included
433 * Added --global option, which turns on checking of everything. If
434 used with SNMP, the global system health status is also probed, to
435 protect the user against bugs in the plugin. If used with omreport,
436 the overall chassis health is used.
437 * Support for SNMP version 3
438 * New check added: esmhealth. This checks the overall health of the
439 ESM log, i.e. the fill grade. More than 80% means a warning message
440 * Fixed alert log reporting to use the same format as for the ESM log
441 * Output messages are now sorted by severity
442 * Minor changes in how out-of-date controller firmware/driver is
444 * Code refactoring and cleanup
449 * Use "omreport about" to collect OMSA version. Slightly faster than
450 "omreport system version". This should give a small speedup in
451 certain configurations
452 * Fixed typo in output when a logical drive is rebuilding. Thanks to
453 Andreas Olsson for reporting
454 * Improved reporting of ESM log content
455 * Added omreport.sh as alternate omreport path
456 * Lots of other small fixes and enhancements
458 Plus: A few changes to make the plugin work with old PowerEdge models
459 (e.g. 2550, 2450) and/or old OMSA versions (e.g. version 4.5):
461 * Use the chassisModelName OID to determine if SNMP works (instead of
463 * No longer require a response when checking baseboard type via
464 SNMP. If there is no response, we assume that we're not dealing with
467 Thanks to Christian McHugh for help with testing and debugging this
473 * Use 'omreport system operatingsystem' to collect OS info, instead of
474 'omreport system' version which is incredibly slow. This should speed
475 things up in certain configurations.
476 * A few speedups, don't collect information that isn't needed
482 * New option --linebreak to specify the separator between line in case
484 * Added support for 64bit Windows. Thanks to Patrick Hemmen for a patch
485 * [Patrick Hemmen] Added install.bat for Windows installation
486 * [Patrick Hemmen] Improvements on install.sh. Will now install in
487 /usr/lib64 for x86_64
488 * RPMs are now architecture dependent, because of different libdir
493 * New option -o|--ok-info to display extra information when everything
494 is ok. The plugin can now display storage firmware and driver info,
495 DRAC and BMC firmware, and OMSA version
496 * Support for setting custom minimum temperature thresholds via the
497 -c|--critical and -w|--warning options
498 * Better and more detailed temperature error reporting
499 * Bugfix in the amperage report (including performance data). The
500 plugin now takes into account the correct unit and measurement for
501 amperage probes (other than watts)
502 * New option --port lets the user specify the remote SNMP port number
507 * Regression fix: Use the older Processor Device SNMP OIDs for older
508 PowerEdge models, that don't have the new Processor Device Status
509 OIDs. Thanks to Nicole Hähnel for reporting this bug.
510 * Default output (when there are no alerts) now shows RAC firmware,
511 BMC firmware, info about controllers and enclosures (firmware,
517 * Regression fix: Ignore unoccupied CPU slots with SNMP probing. This
518 fixes a bug introduced in versjon 3.2.1, which would output
519 something like this if one or more CPU slots were empty: CPU 1 needs
525 * Use Processor Device Status Table OIDs instead of Processor Device
526 Table when checking CPUs via SNMP
527 * Bugfix: don't report throttled CPUs as warnings when checking via
528 SNMP (same as for checking locally)
533 * New options --state and --short-state for displaying service state
535 * Lots of small fixes for code readability and maintainability
540 * Support for running natively on Windows (using omreport.exe). Thanks
541 to Peter Jestico for a patch.
542 * Support for compiled Windows version, i.e. check_openmanage.exe is
543 now a legal script name.
544 * Exit with error if script basename is illegal/unknown
545 * Various small fixes
550 * Use of alternate basenames for checking only one class of components
551 * Added support for checking the ESM log via SNMP
552 * Code refactoring for robustness and maintainability
553 * Numerous small fixes and enhancements
554 * Added install script in distribution tarball
559 * The script no longer aborts if it can't get system information via
560 SNMP. Give a warning instead, as this is not a critical error
561 * Increased robustness when checking controllers
566 * Man page fix in the 'check' section. Thanks to Ansgar Dahlen for
568 * Allow invalid command error from 'omreport chassis pwrmonitoring'
569 * Various small fixes
574 * Use unique IDs for storage components with regard to blacklisting,
575 which means that the blacklisting API has changed
576 * Added checks for storage components: connectors (channels),
577 enclosures, enclosure fans, enclosure power supplies, enclosure
578 temperature probes and enclosure management modules (EMMs)
579 * Improved verbose output
580 * New option -t|--timeout for setting the plugin timeout
581 * New option -w|--warning for setting custom temperature warning
583 * New option -c|--critical for setting custom temperature critical
585 * Option --check can no longer be specified in its short form (-c)
586 * Code cleanup and improvements
591 * The workaround for the OMSA bug introduced in OMSA 5.5.0 didn't take
592 multiple controllers into account. This has been fixed.
597 * New option -i|--info prefixes all alerts with the service tag
598 * New option -e|--extinfo gives and extra line of output in case of an
599 alert (model and service tag)
600 * New option --postmsg lets the user specify a post message string,
601 with info such as model, service tag etc.
602 * Options -b|--blacklist and -c|--check can now be specified multiple
603 times (actually quite useful)
608 * Slightly improved output for alerts on logical drives (vdisks)
609 * Now shows a rebuilding physical disk as a warning, as this is
610 usually accompanied by a degraded vdisk. Previous versions didn't
611 show this at all (omreport classifies it as "OK").
616 * Slightly improved output for charging controller batteries
621 * Bugfix for reporting physical drives with predictive failure (both
627 * Fix bug in option handling (ambiguous options)
628 * Slightly improved output if checking the storage subsystem is turned
630 * Don't complain if there are no logical drives. This is OK. Thanks to
631 Jamie Henderson for reporting this
636 * Fix bug in SNMP status level table
641 * Added workaround for a BUG introduced in OpenManage 5.5.0. OM
642 sometimes adds a newline in the controller driver version name,
643 which leads to problems parsing the output. Thanks to Hiren Patel
644 for bringing this to my attention.
649 * (snmp) Improved handling of cases where OM is not working properly
654 * Fixed issue where controller number for physical disks can't be
655 established via SNMP (now identifies as controller no. -1)
660 * Correctly identifies and reports error condition in which OpenManage
661 has stopped working (it happens)
667 * Same options for checking, blacklisting etc. supported with SNMP
668 * Same output with SNMP as with NRPE
673 * Collects performance data if the option '-p' or '--perfdata' is
675 * New blacklisting directives ctrl_fw and ctrl_driver
676 added. Suppresses the "special" warning messages concerning outdated
677 controller firmware and driver. Useful if you can't or won't
683 * Fix getting system model and serial number for newer blades
688 * Three new checks added:
689 - System battery probes (typical CMOS battery). Newer poweredge
691 - Power consumption monitoring (if the server supports it)
692 - ESM log, with same functionality as the alert log check. Disabled
698 * Internal refactoring: use ssv-formatted output from openmanage,
699 resulting in slightly faster execution and increased robustness.
700 * If /usr/bin/omreport doesn't exist, try
701 /opt/dell/srvadmin/oma/bin/omreport.
702 * Allow for no instrumented/redundant power supplies. Needed on
703 low-end poweredge models and blades.
708 * Openmanage reports non-critical warning about throttled CPUs on new
709 hardware models. Most og us use ondemand CPU frequency scaling (with
710 throttled CPUs as a result). This specific non-critical warning (CPU
711 Throttled) is ignored from now on.
712 * Remove superfluous Celcius sign when reporting temperatures.
717 * Accommodate blade systems with no fans or powersupplies, i.e. accept
718 errors from omreport when trying to check fans or powersupplies on
720 * Accommodate newer hardware with slightly different omreport
721 options. Use the newer options if they exist. Not really necessary
722 yet, but deprecated options may be removed in future versions of
728 * When everything is OK, check_openmanage now outputs the same info as
729 Gerhard Lausser's excellent check_hpasm plugin does for HP servers:
731 OK - System: 'poweredge 2850', S/N: 'XXXXXXX', ROM: 'A06
732 10/03/2006', hardware working fine, 2 logical drives, 4 physical
