Need to track disk SMART stats in Zabbix? I found a fairly simple method that does not rely on external scripts (other than the Zabbix agent).
1) Edit your Zabbix Agent config to permit remote commands if you have not already done so. It’s usually /etc/zabbix/zabbix_agentd.conf
2) Near the bottom of your agent config there should be several “UserParamerter=…” lines, add a new one:
UserParameter=hdd.smart[*],sudo smartctl -A /dev/$1 | grep -E -i '^[ ]*($2)[ ]' | cut -c88-
In short, this command spits out a full SmartMonTools report for your drive ($1), greps it for a single specific line ($2), then removes the first 88 characters, leaving only the raw value behind.
Make sure that smartctl is in your suroers file for any user to run without a password prompt. I detail that process in a previous post.
