Topic on zabbix forum

LSI_RAID_valuemaps

Zabbix value mappings for "Template LSI RAID". Should be imported before template via "Administration" -> "General" -> "Value mapping" -> "Import".

Available items:

LSI RAID BBU & LD Status

• 0 -> Optimal
• 1 -> Failed

LSI RAID PhysDrv Status

• 0 -> (Online|Hostpare|Unconfigured good)
• 1 -> Failed
• 2 -> Rebuild

LSI_RAID_template

Available items:

Adapter

• Adapter model
• Firmware version

Battery Backup Unit

• BBU State (+trigger)
• BBU State of charge (+trigger)
• BBU manufacture date (disabled by default)
• BBU design capacity (disabled by default)
• BBU current capacity (disabled by default)

Physical drives

• Firmware state (+trigger)
• Predictive errors (+trigger)
• Media errors (+trigger)
• Size

Scripts

3 scripts are available for windows (powershell) and unix (perl) servers

RAID Discovery script

This script is used for Low Level Discovery of RAID configuration. Scripts uses zabbix_sender and agent configuration file to report RAID configuration to zabbix.

RAID checks script

This script is used by zabbix agent to check "non critical" items, such as adapter model, physical drive size, etc. But this script also supports checking of all items from template (i.e. you can change type for all items from 'Zabbix trapper' to 'Zabbix Agent'). I've created "trapper" version of this script, because zabbix agent very often reports that some item is not supported (I noticed that problem only on Windows servers). Probably there are some locking occurs, when zabbix agent checks a lot of items at the same time.

RAID "trapper" check script

This scrips reports all values for "critical" items at once. Currently it reports BBU state and state of charge, physical drives state, predictive and media erros, logical volumes states. All other checks are performed by zabbix agent using RAID checks scripts and userparameters.

Discovery and "trapper" scripts are executed by system scheduler.

Agent userparameters:

Windows

UserParameter=hw.raid.physical_disk[*],C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -File "C:\Program Files\zabbix_agent\raid_check.ps1" -mode pdisk -item $4 -adapter $1 -enc $2 -pdisk $3
UserParameter=hw.raid.logical_disk[*],C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -File "C:\Program Files\zabbix_agent\raid_check.ps1" -mode vdisk -item $3 -adapter $1 -vdisk $2
UserParameter=hw.raid.bbu[*],C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -File "C:\Program Files\zabbix_agent\raid_check.ps1" -mode bbu -item $2 -adapter $1
UserParameter=hw.raid.adapter[*],C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -File "C:\Program Files\zabbix_agent\raid_check.ps1" -mode adapter -item $2 -adapter $1

Unix/Linux

UserParameter=hw.raid.physical_disk[*],/usr/bin/perl -w /etc/zabbix/scripts/raid_check.pl -mode pdisk -item $4 -adapter $1 -enclosure $2 -pdisk $3
UserParameter=hw.raid.logical_disk[*],/usr/bin/perl -w /etc/zabbix/scripts/raid_check.pl -mode vdisk -item $3 -adapter $1 -vdisk $2
UserParameter=hw.raid.bbu[*],/usr/bin/perl -w /etc/zabbix/scripts/raid_check.pl -mode bbu -item $2 -adapter $1
UserParameter=hw.raid.adapter[*],/usr/bin/perl -w /etc/zabbix/scripts/raid_check.pl -mode adapter -item $2 -adapter $1

For agents on unix servers RAID tool should be executed via sudo, add this to sudoers file:

Defaults:zabbix !requiretty
# path to your tool can be different
zabbix  ALL=NOPASSWD:/opt/MegaRAID/CmdTool2/CmdTool2

Scheduled Tasks

The script raid_trapper_checks must be run via cron/scheduled tasks. There is a trigger defined that alerts when the data is older than 10 minutes, so the script should be executed every 5 minutes or so.

Windows

Adapt the paths in raid_trapper_checks_task.xml to your needs and import it in the Task Scheduler.

Linux/Unix

# crontab -e -u zabbix
* */5 * * * perl /path/to/your/raid_trapper_check.pl

I'm not a programmer, so code review will be appreciated :)
