Monitoring TBW (Total Bytes Written) for Samsung SATA SSDs

[danboid]

I was already using templates to monitor ZFS and mdadm on my Linux servers on top of whatever disk properties the standard Zabbix Linux template monitors but it turns out that is not enough as I also need to be monitoring the TBW (Total Bytes Written) of my SSD disks. It would seem that when the TBW of a disk dips below 90% or so, you probably need to replace that disk because performance notably degrades, certainly it does so in RAIDZ pools.

There are a couple of scripts and one-liners to calculate your disks TBW on the command line using smartctl here:

Has anyone already written a Zabbix template to monitor the TBW of Samsung SATA SSDs? I have already opened a ticket requesting that Zabbix add this to their smartctl because that doesn't support monitoring TBW yet it seems.

Thanks

This ended up in a change request, so will add it here: https://support.zabbix.com/browse/ZBXNEXT-8700
