4 * Added robustness for received SNMP values that are not defined in
5 the MIB. Instead of throwing a perl warning when this happens, the
6 plugin will not report the undefined value.
7 * Defined "Replacing" as a defined state for physical disks in SNMP
8 mode, even though this state is not defined in the MIB. It is
9 reported as such by omreport.
10 * Physical disk brand/model is now reported when the state of the disk
11 is "Rebuilding" or "Replacing".
12 * The state of a physical disk is reported in parentheses when the
13 predictive failure is detected. It is useful to know if a disk is
14 online, offline, spare or even failed when predictive failure is
16 * Handling of physical disk predictive failure has been improved
18 * Refactoring of the perfdata code. In conformance with the plugin
19 development guidelines, the UOM (unit of measure) previously
20 reported in the perfdata output has been removed.
21 * The -p or --perfdata option now
22 takes an optional agrument 'minimal', which triggers shorter names
23 for the perfomance data labels. This shortens the output and is a
24 workaround for systems where the amount of output exceeds the 1024
26 * The PNP4Nagios template has been updated. Users of check_openmanage
27 and PNP4Nagios are advised to upgrade. This version of
28 check_openmanage needs the new template.
29 * Lots of other small improvements and updates.
35 * New option '--use-get_table' is added as a workaround for SNMPv3 on
36 Windows using net-snmp. This option will make check_openmanage use
37 the Net::SNMP function get_table() instead of get_entries() to
38 collect information via SNMP.
39 * Include a blacklisting option 'ctrl_pdisk' which takes the
40 controller number as argument. This blacklisting option only works
41 with omreport and is a workaround for broken disk firmwares that
42 contain illegal XML characters. These characters makes openmanage
43 barf and exit with an error. Patch from Bas Couwenberg.
44 * If the blacklisting keyword "all" is supplied for a component type,
45 that component type is not checked at all, i.e. the commands are
46 never executed. This will make check_openmanage execute faster if
47 blacklisting is heavily used.
48 * Option '--htmlinfo' now has a shorter equivalent '-I'
49 * The option '--short-state' now has a shorter equivalent '-S'
55 * Fixed an SNMP bug where the plugin didn't handle OID indexes that
56 were not sequential. Thanks to Gianluca Varenni for reporting.
57 * Fixed an SNMP bug when checking old hardware such as the PE 2650 and
58 PE 750. The controller id for physical drives were collected and
59 displayed incorrectly. This release uses an additional OID to fetch
60 this info, which would otherwise be unavailable. Thanks to Gianluca
61 Varenni for reporting this bug.
62 * Should use %snmp_probestatus, not %snmp_status when checking the
63 status of voltage probes. Thanks to Ken McKinlay for a patch.
64 * Fix when identifying blades via SNMP with very old OMSA
65 versions. Patch from Ken McKinlay.
66 * Better way of finding the ID of physical drives via SNMP
72 * Added support for storport driver version for controllers, only
73 applicable on servers running Windows. A new blacklisting keyword
74 for suppressing storport driver messages was added.
75 * The "all" keyword in blacklisting is now case insensitive.
76 * More fine-grained reporting in the rare case where a controller
77 battery fails during learning and charging states.
78 * New improved way of reporting perl warnings during execution of the
85 * Fix for path to omreport on Linux with OMSA 6.2.0
86 * A couple of other small fixes
92 * Fix for undefined device name for logical drives (thanks to Pontus
94 * Fixed a bug in the PNP4Nagios template, that prevented the template
95 from working with PNP4Nagios 0.6. Thanks to the PNP4Nagios team for
102 * CPU type, family etc. are now reported in case of a CPU failure (and
104 * The debug output now reports Openmanage version and plugin version
110 * New option '-a' or '--all' turns on checking of everything
111 * The manual page (POD info) is removed from the script and is now in
112 a separate file, to make check_openmanage fully ePN compatible
113 * ePN is no longer disabled by default, check_openmanage no longer has
114 an opinion on whether it should run under ePN or not
115 * The '-m' or '--man' option is no longer available
116 * The option '-v' or '--verbose' is renamed to '-d' or '--debug',
117 which makes more sense wrt. its usage
118 * The '-g' or '--global' option is removed. Checking the global health
119 status is now default if applicable
120 * Checking intrusion detection is now turned on by default
121 * The obsolete option '--snmp' is removed
122 * The option '--state' now has a shorter equivalent '-s'
123 * The basename stuff and options '--only-critical' and
124 '--only-warning' are now replaced by an option '--only'
125 * If plugin is run by Nagios, redirect stderr to stdout
126 * Added option '--omreport', that lets the user specify the full path
127 to the omreport binary
128 * Added non-8bit-legacy default search paths for omreport.exe for
130 * Minor changes to the plugin output, for consistency
131 * New blacklisting keyword 'bat_charge' disables warning messages
132 related to controller cache battery charging. Thanks to Robert
133 Heinzmann for a patch.
134 * For blacklisting, the component ID kan now be "ALL", in which all
135 components of that type is blacklisted.
136 * Man page is moved to manual section 8
142 * Fixed a bug that could cause errors and weird results when checking
143 cooling devices (fans) via SNMP. Thanks to Ken McKinlay for spotting
144 this bug and reporting it.
149 * For failed physical drives, check_openmanage will now output the
150 drive's vendor, model and size in GB or TB.
155 * The -s|--snmp option was redundant and no longer does anything. SNMP
156 is triggered automatically if the -H|--hostname option is
157 present. The -s|--snmp option is kept for compatibility, but has no
163 * Added support for performance data (temperatures) from attached
164 storage enclosures such as the MD1000
169 * Fixed a regression in the --htmlinfo option when it is not supplied
175 * New option --htmlinfo adds clickable HTML links in the plugin's
181 * Fixed a regression bug in CPU and power supply reporting that only
182 affects verbose output
183 * If blacklisting is used, the global health check (via the --global
184 option) is now negated. Checking the global health doesn't make
185 sense when one or more components is blacklisted. Thanks to Rene
186 Beaulieu for reporting this bug
187 * The PNP4Nagios template is now included in the tarball and zip
193 * Improved memory error reporting, when using omreport
194 * Collect performance data from pwrmonitoring (amperage probes) that
195 were previously ignored when using omreport
200 * Improved memory error reporting, when using SNMP
201 * Other small ehnancements
206 * The plugin is now compatible with the Nagios embedded Perl
207 interpreter (ePN) in theory. However, the plugin will not not use
208 ePN by default. We don't want any "accidents".
209 * License is now GPLv3, previously only specified as "GPL"
210 * New options --only-critical and --only-warning. With these options
211 the plugin will only print critical or warning alerts, respectively.
212 * Bugfixes and speed enhancements in the storage section, when
213 checking enclosure components via omreport
214 * The --okinfo option is now less verbose and more to the point
215 * Lots of code refactoring for readability, maintainability and
221 * Fixed a bug in the storage section, when checking controllers. This
222 is an obscure bug that only manifests itself in the odd case where a
223 server has multiple controllers, and one of the controllers are
224 missing some of the OIDs, in which case these OIDs will be missing
225 for the other controllers as well. The change is minor and only
226 includes using get_table() instead of get_entries() to collect the
227 SNMP result. Thanks to Stephan Bovet for reporting this bug.
232 * The --perfdata option can now optionally take an argument
233 "multiline", which makes the plugin produce multiline performance
234 data output in a Nagios 3.x way. Not really needed, but the plugin
236 * Added comment within the 10 first lines to disable the nagios
237 embedded perl (ePN) interpreter by default for Nagios 3.x
238 * Improvements in the performance data output. Units are now included
243 * Added --global option, which turns on checking of everything. If
244 used with SNMP, the global system health status is also probed, to
245 protect the user against bugs in the plugin. If used with omreport,
246 the overall chassis health is used.
247 * Support for SNMP version 3
248 * New check added: esmhealth. This checks the overall health of the
249 ESM log, i.e. the fill grade. More than 80% means a warning message
250 * Fixed alert log reporting to use the same format as for the ESM log
251 * Output messages are now sorted by severity
252 * Minor changes in how out-of-date controller firmware/driver is
254 * Code refactoring and cleanup
259 * Use "omreport about" to collect OMSA version. Slightly faster than
260 "omreport system version". This should give a small speedup in
261 certain configurations
262 * Fixed typo in output when a logical drive is rebuilding. Thanks to
263 Andreas Olsson for reporting
264 * Improved reporting of ESM log content
265 * Added omreport.sh as alternate omreport path
266 * Lots of other small fixes and enhancements
268 Plus: A few changes to make the plugin work with old PowerEdge models
269 (e.g. 2550, 2450) and/or old OMSA versions (e.g. version 4.5):
271 * Use the chassisModelName OID to determine if SNMP works (instead of
273 * No longer require a response when checking baseboard type via
274 SNMP. If there is no response, we assume that we're not dealing with
277 Thanks to Christian McHugh for help with testing and debugging this
283 * Use 'omreport system operatingsystem' to collect OS info, instead of
284 'omreport system' version which is incredibly slow. This should speed
285 things up in certain configurations.
286 * A few speedups, don't collect information that isn't needed
292 * New option --linebreak to specify the separator between line in case
294 * Added support for 64bit Windows. Thanks to Patrick Hemmen for a patch
295 * [Patrick Hemmen] Added install.bat for Windows installation
296 * [Patrick Hemmen] Improvements on install.sh. Will now install in
297 /usr/lib64 for x86_64
298 * RPMs are now architecture dependent, because of different libdir
303 * New option -o|--ok-info to display extra information when everything
304 is ok. The plugin can now display storage firmware and driver info,
305 DRAC and BMC firmware, and OMSA version
306 * Support for setting custom minimum temperature thresholds via the
307 -c|--critical and -w|--warning options
308 * Better and more detailed temperature error reporting
309 * Bugfix in the amperage report (including performance data). The
310 plugin now takes into account the correct unit and measurement for
311 amperage probes (other than watts)
312 * New option --port lets the user specify the remote SNMP port number
317 * Regression fix: Use the older Processor Device SNMP OIDs for older
318 PowerEdge models, that don't have the new Processor Device Status
319 OIDs. Thanks to Nicole Hähnel for reporting this bug.
320 * Default output (when there are no alerts) now shows RAC firmware,
321 BMC firmware, info about controllers and enclosures (firmware,
327 * Regression fix: Ignore unoccupied CPU slots with SNMP probing. This
328 fixes a bug introduced in versjon 3.2.1, which would output
329 something like this if one or more CPU slots were empty: CPU 1 needs
335 * Use Processor Device Status Table OIDs instead of Processor Device
336 Table when checking CPUs via SNMP
337 * Bugfix: don't report throttled CPUs as warnings when checking via
338 SNMP (same as for checking locally)
343 * New options --state and --short-state for displaying service state
345 * Lots of small fixes for code readability and maintainability
350 * Support for running natively on Windows (using omreport.exe). Thanks
351 to Peter Jestico for a patch.
352 * Support for compiled Windows version, i.e. check_openmanage.exe is
353 now a legal script name.
354 * Exit with error if script basename is illegal/unknown
355 * Various small fixes
360 * Use of alternate basenames for checking only one class of components
361 * Added support for checking the ESM log via SNMP
362 * Code refactoring for robustness and maintainability
363 * Numerous small fixes and enhancements
364 * Added install script in distribution tarball
369 * The script no longer aborts if it can't get system information via
370 SNMP. Give a warning instead, as this is not a critical error
371 * Increased robustness when checking controllers
376 * Man page fix in the 'check' section. Thanks to Ansgar Dahlen for
378 * Allow invalid command error from 'omreport chassis pwrmonitoring'
379 * Various small fixes
384 * Use unique IDs for storage components with regard to blacklisting,
385 which means that the blacklisting API has changed
386 * Added checks for storage components: connectors (channels),
387 enclosures, enclosure fans, enclosure power supplies, enclosure
388 temperature probes and enclosure management modules (EMMs)
389 * Improved verbose output
390 * New option -t|--timeout for setting the plugin timeout
391 * New option -w|--warning for setting custom temperature warning
393 * New option -c|--critical for setting custom temperature critical
395 * Option --check can no longer be specified in its short form (-c)
396 * Code cleanup and improvements
401 * The workaround for the OMSA bug introduced in OMSA 5.5.0 didn't take
402 multiple controllers into account. This has been fixed.
407 * New option -i|--info prefixes all alerts with the service tag
408 * New option -e|--extinfo gives and extra line of output in case of an
409 alert (model and service tag)
410 * New option --postmsg lets the user specify a post message string,
411 with info such as model, service tag etc.
412 * Options -b|--blacklist and -c|--check can now be specified multiple
413 times (actually quite useful)
418 * Slightly improved output for alerts on logical drives (vdisks)
419 * Now shows a rebuilding physical disk as a warning, as this is
420 usually accompanied by a degraded vdisk. Previous versions didn't
421 show this at all (omreport classifies it as "OK").
426 * Slightly improved output for charging controller batteries
431 * Bugfix for reporting physical drives with predictive failure (both
437 * Fix bug in option handling (ambiguous options)
438 * Slightly improved output if checking the storage subsystem is turned
440 * Don't complain if there are no logical drives. This is OK. Thanks to
441 Jamie Henderson for reporting this
446 * Fix bug in SNMP status level table
451 * Added workaround for a BUG introduced in OpenManage 5.5.0. OM
452 sometimes adds a newline in the controller driver version name,
453 which leads to problems parsing the output. Thanks to Hiren Patel
454 for bringing this to my attention.
459 * (snmp) Improved handling of cases where OM is not working properly
464 * Fixed issue where controller number for physical disks can't be
465 established via SNMP (now identifies as controller no. -1)
470 * Correctly identifies and reports error condition in which OpenManage
471 has stopped working (it happens)
477 * Same options for checking, blacklisting etc. supported with SNMP
478 * Same output with SNMP as with NRPE
483 * Collects performance data if the option '-p' or '--perfdata' is
485 * New blacklisting directives ctrl_fw and ctrl_driver
486 added. Suppresses the "special" warning messages concerning outdated
487 controller firmware and driver. Useful if you can't or won't
493 * Fix getting system model and serial number for newer blades
498 * Three new checks added:
499 - System battery probes (typical CMOS battery). Newer poweredge
501 - Power consumption monitoring (if the server supports it)
502 - ESM log, with same functionality as the alert log check. Disabled
508 * Internal refactoring: use ssv-formatted output from openmanage,
509 resulting in slightly faster execution and increased robustness.
510 * If /usr/bin/omreport doesn't exist, try
511 /opt/dell/srvadmin/oma/bin/omreport.
512 * Allow for no instrumented/redundant power supplies. Needed on
513 low-end poweredge models and blades.
518 * Openmanage reports non-critical warning about throttled CPUs on new
519 hardware models. Most og us use ondemand CPU frequency scaling (with
520 throttled CPUs as a result). This specific non-critical warning (CPU
521 Throttled) is ignored from now on.
522 * Remove superfluous Celcius sign when reporting temperatures.
527 * Accommodate blade systems with no fans or powersupplies, i.e. accept
528 errors from omreport when trying to check fans or powersupplies on
530 * Accommodate newer hardware with slightly different omreport
531 options. Use the newer options if they exist. Not really necessary
532 yet, but deprecated options may be removed in future versions of
538 * When everything is OK, check_openmanage now outputs the same info as
539 Gerhard Lausser's excellent check_hpasm plugin does for HP servers:
541 OK - System: 'poweredge 2850', S/N: 'XXXXXXX', ROM: 'A06
542 10/03/2006', hardware working fine, 2 logical drives, 4 physical
