4 * Storage is no longer allowed to be absent. If the plugin doesn't
5 find a storage controller, it will give an alert. For diskless
6 systems or servers without a Dell controller that OMSA recognizes
7 you will now have to specify '--no-storage' or '--check storage=0'
9 * Report the system revision (if applicable) wherever the model name
10 is printed. E.g. "PowerEdge 2950 III" instead of "PowerEdge 2950".
11 * Small change in search path for omreport: The new location for OMSA
12 6.2.0 and later on Linux will be attempted first.
13 * Small bugfix for the '--check' parameter, if the argument is a
14 filename. The file could not contain a linebreak, this has been
16 * Added an option '--no-storage', which is equivalent to the general
17 option '--check storage=0'.
23 * If a physical disk is a hot spare, display this information in
25 * Report the bus protocol (e.g. SAS, SATA) and media type (e.g. HDD,
26 SDD) for physical disks in the debug output, if applicable
27 * Minor fix for 100GB physical disks, write "100GB" instead of "99GB"
28 * SNMP: Use new features of OMSA 6.3.0 to display occupied and total
29 slots in storage enclosures, if applicable. This information is not
30 available with omreport and check_openmanage will not display this
32 * SNMP: Added new processor IDs from the OMSA 6.3.0 MIBs
33 * SNMP: Use connection tables in a proper way to determine controller
34 and enclosure IDs, for use with physical disks and enclosure
35 components (fan, temp sensors etc.). This fixes a long standing bug
36 for servers with more than one controller, if checked via SNMP.
37 * SNMP: Use the nexus ID as last resort to find the controller for
38 physical disks. Workaround for older, broken OMSA versions.
39 * SNMP: Identify enclosures (e.g. '2:0:0') properly so that the
40 reporting with SNMP corresponds to the same report with omreport.
41 * SNMP: added a couple of workarounds for pre-historic OMSA versions
47 * More fine-grained reporting of temperature warnings for enclosure
49 * Max/min temperature limits for enclosure temp probes are reported in
51 * Report enclosure temperature probes that are "Inactive" as ok
52 * Don't try to print out the reading of enclosure temperature probes
53 if the reading doesn't exist or is not an integer
54 * Report enclosure EMMs that are "Not Installed" as ok, instead of
56 * Corrected typo in the PNP4Nagios template
62 * Remove reporting of which controller a logical drive is "attached"
63 to, since this information can't be reliably extracted via SNMP.
64 * Avoid collecting Lun ID via SNMP for virtual disks, we don't use it
65 * Report total memory and number of dimms in the ok output
66 * Difference in reporting if amperage probes have discrete readings
67 * Workaround for broken amperage probes
68 * Added workaround for bad temperature probes that yields no reading
70 * Get OMSA version via SNMP slightly more efficiently
76 * Added robustness for received SNMP values that are not defined in
77 the MIB. Instead of throwing a perl warning when this happens, the
78 plugin will not report the undefined value.
79 * Defined "Replacing" as a defined state for physical disks in SNMP
80 mode, even though this state is not defined in the MIB. It is
81 reported as such by omreport.
82 * Physical disk brand/model is now reported when the state of the disk
83 is "Rebuilding" or "Replacing".
84 * The state of a physical disk is reported in parentheses when
85 predictive failure is detected. It is useful to know if a disk is
86 online, offline, spare or even failed when predictive failure is
88 * Handling of physical disk predictive failure has been improved
90 * Refactoring of the perfdata code. In conformance with the plugin
91 development guidelines, the UOM (unit of measure) previously
92 reported in the perfdata output has been removed.
93 * The -p or --perfdata option now
94 takes an optional agrument 'minimal', which triggers shorter names
95 for the perfomance data labels. This shortens the output and is a
96 workaround for systems where the amount of output exceeds the 1024
98 * The PNP4Nagios template has been updated. Users of check_openmanage
99 and PNP4Nagios are advised to upgrade. This version of
100 check_openmanage needs the new template.
101 * Lots of other small improvements and updates.
107 * New option '--use-get_table' is added as a workaround for SNMPv3 on
108 Windows using net-snmp. This option will make check_openmanage use
109 the Net::SNMP function get_table() instead of get_entries() to
110 collect information via SNMP.
111 * Include a blacklisting option 'ctrl_pdisk' which takes the
112 controller number as argument. This blacklisting option only works
113 with omreport and is a workaround for broken disk firmwares that
114 contain illegal XML characters. These characters makes openmanage
115 barf and exit with an error. Patch from Bas Couwenberg.
116 * If the blacklisting keyword "all" is supplied for a component type,
117 that component type is not checked at all, i.e. the commands are
118 never executed. This will make check_openmanage execute faster if
119 blacklisting is heavily used.
120 * Option '--htmlinfo' now has a shorter equivalent '-I'
121 * The option '--short-state' now has a shorter equivalent '-S'
127 * Fixed an SNMP bug where the plugin didn't handle OID indexes that
128 were not sequential. Thanks to Gianluca Varenni for reporting.
129 * Fixed an SNMP bug when checking old hardware such as the PE 2650 and
130 PE 750. The controller id for physical drives were collected and
131 displayed incorrectly. This release uses an additional OID to fetch
132 this info, which would otherwise be unavailable. Thanks to Gianluca
133 Varenni for reporting this bug.
134 * Should use %snmp_probestatus, not %snmp_status when checking the
135 status of voltage probes. Thanks to Ken McKinlay for a patch.
136 * Fix when identifying blades via SNMP with very old OMSA
137 versions. Patch from Ken McKinlay.
138 * Better way of finding the ID of physical drives via SNMP
144 * Added support for storport driver version for controllers, only
145 applicable on servers running Windows. A new blacklisting keyword
146 for suppressing storport driver messages was added.
147 * The "all" keyword in blacklisting is now case insensitive.
148 * More fine-grained reporting in the rare case where a controller
149 battery fails during learning and charging states.
150 * New improved way of reporting perl warnings during execution of the
157 * Fix for path to omreport on Linux with OMSA 6.2.0
158 * A couple of other small fixes
164 * Fix for undefined device name for logical drives (thanks to Pontus
166 * Fixed a bug in the PNP4Nagios template, that prevented the template
167 from working with PNP4Nagios 0.6. Thanks to the PNP4Nagios team for
174 * CPU type, family etc. are now reported in case of a CPU failure (and
176 * The debug output now reports Openmanage version and plugin version
182 * New option '-a' or '--all' turns on checking of everything
183 * The manual page (POD info) is removed from the script and is now in
184 a separate file, to make check_openmanage fully ePN compatible
185 * ePN is no longer disabled by default, check_openmanage no longer has
186 an opinion on whether it should run under ePN or not
187 * The '-m' or '--man' option is no longer available
188 * The option '-v' or '--verbose' is renamed to '-d' or '--debug',
189 which makes more sense wrt. its usage
190 * The '-g' or '--global' option is removed. Checking the global health
191 status is now default if applicable
192 * Checking intrusion detection is now turned on by default
193 * The obsolete option '--snmp' is removed
194 * The option '--state' now has a shorter equivalent '-s'
195 * The basename stuff and options '--only-critical' and
196 '--only-warning' are now replaced by an option '--only'
197 * If plugin is run by Nagios, redirect stderr to stdout
198 * Added option '--omreport', that lets the user specify the full path
199 to the omreport binary
200 * Added non-8bit-legacy default search paths for omreport.exe for
202 * Minor changes to the plugin output, for consistency
203 * New blacklisting keyword 'bat_charge' disables warning messages
204 related to controller cache battery charging. Thanks to Robert
205 Heinzmann for a patch.
206 * For blacklisting, the component ID kan now be "ALL", in which all
207 components of that type is blacklisted.
208 * Man page is moved to manual section 8
214 * Fixed a bug that could cause errors and weird results when checking
215 cooling devices (fans) via SNMP. Thanks to Ken McKinlay for spotting
216 this bug and reporting it.
221 * For failed physical drives, check_openmanage will now output the
222 drive's vendor, model and size in GB or TB.
227 * The -s|--snmp option was redundant and no longer does anything. SNMP
228 is triggered automatically if the -H|--hostname option is
229 present. The -s|--snmp option is kept for compatibility, but has no
235 * Added support for performance data (temperatures) from attached
236 storage enclosures such as the MD1000
241 * Fixed a regression in the --htmlinfo option when it is not supplied
247 * New option --htmlinfo adds clickable HTML links in the plugin's
253 * Fixed a regression bug in CPU and power supply reporting that only
254 affects verbose output
255 * If blacklisting is used, the global health check (via the --global
256 option) is now negated. Checking the global health doesn't make
257 sense when one or more components is blacklisted. Thanks to Rene
258 Beaulieu for reporting this bug
259 * The PNP4Nagios template is now included in the tarball and zip
265 * Improved memory error reporting, when using omreport
266 * Collect performance data from pwrmonitoring (amperage probes) that
267 were previously ignored when using omreport
272 * Improved memory error reporting, when using SNMP
273 * Other small ehnancements
278 * The plugin is now compatible with the Nagios embedded Perl
279 interpreter (ePN) in theory. However, the plugin will not not use
280 ePN by default. We don't want any "accidents".
281 * License is now GPLv3, previously only specified as "GPL"
282 * New options --only-critical and --only-warning. With these options
283 the plugin will only print critical or warning alerts, respectively.
284 * Bugfixes and speed enhancements in the storage section, when
285 checking enclosure components via omreport
286 * The --okinfo option is now less verbose and more to the point
287 * Lots of code refactoring for readability, maintainability and
293 * Fixed a bug in the storage section, when checking controllers. This
294 is an obscure bug that only manifests itself in the odd case where a
295 server has multiple controllers, and one of the controllers are
296 missing some of the OIDs, in which case these OIDs will be missing
297 for the other controllers as well. The change is minor and only
298 includes using get_table() instead of get_entries() to collect the
299 SNMP result. Thanks to Stephan Bovet for reporting this bug.
304 * The --perfdata option can now optionally take an argument
305 "multiline", which makes the plugin produce multiline performance
306 data output in a Nagios 3.x way. Not really needed, but the plugin
308 * Added comment within the 10 first lines to disable the nagios
309 embedded perl (ePN) interpreter by default for Nagios 3.x
310 * Improvements in the performance data output. Units are now included
315 * Added --global option, which turns on checking of everything. If
316 used with SNMP, the global system health status is also probed, to
317 protect the user against bugs in the plugin. If used with omreport,
318 the overall chassis health is used.
319 * Support for SNMP version 3
320 * New check added: esmhealth. This checks the overall health of the
321 ESM log, i.e. the fill grade. More than 80% means a warning message
322 * Fixed alert log reporting to use the same format as for the ESM log
323 * Output messages are now sorted by severity
324 * Minor changes in how out-of-date controller firmware/driver is
326 * Code refactoring and cleanup
331 * Use "omreport about" to collect OMSA version. Slightly faster than
332 "omreport system version". This should give a small speedup in
333 certain configurations
334 * Fixed typo in output when a logical drive is rebuilding. Thanks to
335 Andreas Olsson for reporting
336 * Improved reporting of ESM log content
337 * Added omreport.sh as alternate omreport path
338 * Lots of other small fixes and enhancements
340 Plus: A few changes to make the plugin work with old PowerEdge models
341 (e.g. 2550, 2450) and/or old OMSA versions (e.g. version 4.5):
343 * Use the chassisModelName OID to determine if SNMP works (instead of
345 * No longer require a response when checking baseboard type via
346 SNMP. If there is no response, we assume that we're not dealing with
349 Thanks to Christian McHugh for help with testing and debugging this
355 * Use 'omreport system operatingsystem' to collect OS info, instead of
356 'omreport system' version which is incredibly slow. This should speed
357 things up in certain configurations.
358 * A few speedups, don't collect information that isn't needed
364 * New option --linebreak to specify the separator between line in case
366 * Added support for 64bit Windows. Thanks to Patrick Hemmen for a patch
367 * [Patrick Hemmen] Added install.bat for Windows installation
368 * [Patrick Hemmen] Improvements on install.sh. Will now install in
369 /usr/lib64 for x86_64
370 * RPMs are now architecture dependent, because of different libdir
375 * New option -o|--ok-info to display extra information when everything
376 is ok. The plugin can now display storage firmware and driver info,
377 DRAC and BMC firmware, and OMSA version
378 * Support for setting custom minimum temperature thresholds via the
379 -c|--critical and -w|--warning options
380 * Better and more detailed temperature error reporting
381 * Bugfix in the amperage report (including performance data). The
382 plugin now takes into account the correct unit and measurement for
383 amperage probes (other than watts)
384 * New option --port lets the user specify the remote SNMP port number
389 * Regression fix: Use the older Processor Device SNMP OIDs for older
390 PowerEdge models, that don't have the new Processor Device Status
391 OIDs. Thanks to Nicole Hähnel for reporting this bug.
392 * Default output (when there are no alerts) now shows RAC firmware,
393 BMC firmware, info about controllers and enclosures (firmware,
399 * Regression fix: Ignore unoccupied CPU slots with SNMP probing. This
400 fixes a bug introduced in versjon 3.2.1, which would output
401 something like this if one or more CPU slots were empty: CPU 1 needs
407 * Use Processor Device Status Table OIDs instead of Processor Device
408 Table when checking CPUs via SNMP
409 * Bugfix: don't report throttled CPUs as warnings when checking via
410 SNMP (same as for checking locally)
415 * New options --state and --short-state for displaying service state
417 * Lots of small fixes for code readability and maintainability
422 * Support for running natively on Windows (using omreport.exe). Thanks
423 to Peter Jestico for a patch.
424 * Support for compiled Windows version, i.e. check_openmanage.exe is
425 now a legal script name.
426 * Exit with error if script basename is illegal/unknown
427 * Various small fixes
432 * Use of alternate basenames for checking only one class of components
433 * Added support for checking the ESM log via SNMP
434 * Code refactoring for robustness and maintainability
435 * Numerous small fixes and enhancements
436 * Added install script in distribution tarball
441 * The script no longer aborts if it can't get system information via
442 SNMP. Give a warning instead, as this is not a critical error
443 * Increased robustness when checking controllers
448 * Man page fix in the 'check' section. Thanks to Ansgar Dahlen for
450 * Allow invalid command error from 'omreport chassis pwrmonitoring'
451 * Various small fixes
456 * Use unique IDs for storage components with regard to blacklisting,
457 which means that the blacklisting API has changed
458 * Added checks for storage components: connectors (channels),
459 enclosures, enclosure fans, enclosure power supplies, enclosure
460 temperature probes and enclosure management modules (EMMs)
461 * Improved verbose output
462 * New option -t|--timeout for setting the plugin timeout
463 * New option -w|--warning for setting custom temperature warning
465 * New option -c|--critical for setting custom temperature critical
467 * Option --check can no longer be specified in its short form (-c)
468 * Code cleanup and improvements
473 * The workaround for the OMSA bug introduced in OMSA 5.5.0 didn't take
474 multiple controllers into account. This has been fixed.
479 * New option -i|--info prefixes all alerts with the service tag
480 * New option -e|--extinfo gives and extra line of output in case of an
481 alert (model and service tag)
482 * New option --postmsg lets the user specify a post message string,
483 with info such as model, service tag etc.
484 * Options -b|--blacklist and -c|--check can now be specified multiple
485 times (actually quite useful)
490 * Slightly improved output for alerts on logical drives (vdisks)
491 * Now shows a rebuilding physical disk as a warning, as this is
492 usually accompanied by a degraded vdisk. Previous versions didn't
493 show this at all (omreport classifies it as "OK").
498 * Slightly improved output for charging controller batteries
503 * Bugfix for reporting physical drives with predictive failure (both
509 * Fix bug in option handling (ambiguous options)
510 * Slightly improved output if checking the storage subsystem is turned
512 * Don't complain if there are no logical drives. This is OK. Thanks to
513 Jamie Henderson for reporting this
518 * Fix bug in SNMP status level table
523 * Added workaround for a BUG introduced in OpenManage 5.5.0. OM
524 sometimes adds a newline in the controller driver version name,
525 which leads to problems parsing the output. Thanks to Hiren Patel
526 for bringing this to my attention.
531 * (snmp) Improved handling of cases where OM is not working properly
536 * Fixed issue where controller number for physical disks can't be
537 established via SNMP (now identifies as controller no. -1)
542 * Correctly identifies and reports error condition in which OpenManage
543 has stopped working (it happens)
549 * Same options for checking, blacklisting etc. supported with SNMP
550 * Same output with SNMP as with NRPE
555 * Collects performance data if the option '-p' or '--perfdata' is
557 * New blacklisting directives ctrl_fw and ctrl_driver
558 added. Suppresses the "special" warning messages concerning outdated
559 controller firmware and driver. Useful if you can't or won't
565 * Fix getting system model and serial number for newer blades
570 * Three new checks added:
571 - System battery probes (typical CMOS battery). Newer poweredge
573 - Power consumption monitoring (if the server supports it)
574 - ESM log, with same functionality as the alert log check. Disabled
580 * Internal refactoring: use ssv-formatted output from openmanage,
581 resulting in slightly faster execution and increased robustness.
582 * If /usr/bin/omreport doesn't exist, try
583 /opt/dell/srvadmin/oma/bin/omreport.
584 * Allow for no instrumented/redundant power supplies. Needed on
585 low-end poweredge models and blades.
590 * Openmanage reports non-critical warning about throttled CPUs on new
591 hardware models. Most og us use ondemand CPU frequency scaling (with
592 throttled CPUs as a result). This specific non-critical warning (CPU
593 Throttled) is ignored from now on.
594 * Remove superfluous Celcius sign when reporting temperatures.
599 * Accommodate blade systems with no fans or powersupplies, i.e. accept
600 errors from omreport when trying to check fans or powersupplies on
602 * Accommodate newer hardware with slightly different omreport
603 options. Use the newer options if they exist. Not really necessary
604 yet, but deprecated options may be removed in future versions of
610 * When everything is OK, check_openmanage now outputs the same info as
611 Gerhard Lausser's excellent check_hpasm plugin does for HP servers:
613 OK - System: 'poweredge 2850', S/N: 'XXXXXXX', ROM: 'A06
614 10/03/2006', hardware working fine, 2 logical drives, 4 physical
