Zabbix template handles Software RAID (MD) on Linux

Design and Implementaion:

• auto-discovery for all active MDs
• no assumption made about MD name
• currently, only two HDD/SSD reported as members of the array
• trigger is constructed to monitor RAID State.
• to avoid flipping, the trigger will fire if state change sustain for
  more than one collection cycle

TO DO list

• indtroduce items: failed device, number of failed devices
• auto-discover array devices

Append to zabbix_agentd.conf file

   UserParameter=mdraid[*], sudo /usr/local/bin/zabbix_mdraid.sh -m'$1' -$2'$3'
   
   UserParameter=mdraid.discovery, sudo /usr/local/bin/zabbix_mdraid.sh -D 

Note

don't forget to add zabbix user to sudoers
