check_software_ver

This script was written for Nagios/NRPE, and uses WSH/VBScript. It queries Windows WMI and makes a Software Version Check with optional validation against minimum version, plus a mismatch allowance. It requires one argument (Package Name - $ARG1$), and you can feed it two optional arguments of a version ($ARG2$) for comparison, and a mismatch allowance ($ARG3$) defining how many figures - starting from the right - can be ignored. If just $ARG1$ is provided it simply returns the Software/Version. ($ARG1$ can use % as a wildcard for matching.) If $ARG1$ and $ARG2$ are provided it also makes a strict version check. If $ARG3$ is also provided it makes a version check according to the leeway provided by the argument. (Number must be 1 less that the component count in the version number provided by $ARG2$. Special Cases are "0", meaning strict check, and 99 meaning any later version is OK.) Downside: This will only report software that registers itself with WMI. (All MSI Installations should do this, but many self-installers do not.) Nagios Config: Command: I personally use a custom command for this, as it takes arguments from the service. I also needed to increase the timeout here (as well as in the Nagios/NRPE/NSClient++ configs) because WMI calls can take some time on old hardware. define command { command_name check_nt_software command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -p 5666 -t 300 -c $ARG1$ -a $ARG2$ $ARG3$ $ARG4$ } Service: You'll need a service per package, and I'll use a strict check of Flash Player for my example. (I always tend to give the allowance argument, even though it's not technically required when doing a strict check. I use 0 in these cases.) define service { use INSERT-TEMPLATE-HERE host_name INSERT-HOSTNAME-HERE service_description check_flash_player display_name Check Flash Player Version contact_groups INSERT-GROUPS-HERE check_command check_nt_software!check_software_ver!%flash%player%!11.1.102.62!0 check_interval 10080 notification_interval 10080 } Client Requirements: Windows obviously. (2000 and upwards.) WMI installed and the Win32_Product Class available. (To check, go to an admin command prompt and type "wmic product". If you see a list of software, it's working.) NSClient++ (or similar) Arguments allowed for NRPE. nsc.ini (If using NSClient++) Ensure the following are set. [NRPE] allow_arguments=1 command_timeout=290 [NRPE Handlers] check_software_ver=cscript.exe //NoLogo //T:280 "check_software_ver.wsf" $ARG1$ $ARG2$ $ARG3$ Notes: Return Codes: The following are returned; Unknown: (3) Software Package(s) not found. $ARG3$ Allowance exceeds 3. Critical: (2) $ARG1$ missing or blank. $ARG1$ is literally "$ARG1$" (You've got a Nagios/NRPE/NSClient config problem somewhere.) Version Check with unsuccessful strict match. Software found, but Version Allowance equals or exceeds number of components in the Version given in $ARG2$. Warning: (1) Version Check with unsuccessful match with Allowance OK: (0) Version Report Only Version Check with successful Strict match Version Check with successful match with Allowance Other Execution Examples; (check_command) 1. Report All Adobe Software Versions check_nt_software!check_software_ver!%adobe% 2. Check All Flash Player Levels using strict versioning. check_nt_software!check_software_ver!%Flash%Player%!11.0.1.152 3. Check VMWare Workstation Level ignoring build figure check_nt_software!check_software_ver!%VMWare%Workstation%!7.1.5.19539!1 4. Check VMWare Workstation Level, using specific major version check_nt_software!check_software_ver!%VMWare%Workstation%!7.0!1 5. Check Minimum VMWare Workstation Level, also allowing any higher major version check_nt_software!check_software_ver!%VMWare%Workstation%!7!99 You should be able to work out any command needed from those.
