In zabbix(linux), how can we monitor the file system health, so that we can check for any file system level errors like the one mentioned below happening in some specific disk partition.
EXT4-fs error (device dm-0): mb_free_blocks: double-free of inode 0's block
Is there any specific template available for this. Or should we be going forward with writing custom script to monitor /var/log/messages log for specific error strings.
