Zabbix: LLD monitoring of disks without UserParameter and agent scripts

    In a previous article, I described low-level disk monitoring for Windows machines. I think that the article was quite successful. Therefore, the time has come to actually destroy it. Below we will describe a universal trick for Windows and Linux machines, for which scripts and UserParameters are not needed at all.

    The idea is simple: the Zabbix server will receive everything from smartmontools through external processing and zabbix_get, parse it and pass it on to dependent elements (appeared in Zabbix 3.4). Thus, not only the number of accesses to the monitored server is reduced, but its resources are not spent, since parsing occurs on the side of the Zabbix server.

    One limitation at the moment: only monitoring drives in / dev / sd * format. The format / dev / csmi *, * (Intel Matrix RAID) is not supported due to the fact that zabbix_get considers the comma as the second argument. Correct me if I am wrong.

    What will be needed for implementation:


    Agent setup


    The only thing that deserves attention here is the need to uncomment the EnableRemoteCommands = 1 line , otherwise the agent will not be able to accept commands.

    Smartmontools


    The installation is trivial and will not be considered, however, for Linux there is one need: in order to start without sudo , you need to set the SUID bit to the smartctl file. For Ubuntu, this is sudo chmod u + s / usr / sbin / smartctl .

    Script


    Depending on your zabbix_server.conf configuration file, you need to put this script in the appropriate directory on the Zabbix server. The default for Ubuntu is / usr / lib / zabbix / externalscripts . Do not forget to give the file permission to execute - sudo chmod 775 /usr/lib/zabbix/externalscripts/smartctl.sh .

    Template


    Template exported from version 3.4.4.
    The following elements are already present in the template: model, family, serial number, disk size, SMART status; as well as SMART values ​​3, 5, 7, 9, 10, 190 (194), 196, 197, 198, 199. There are 3 triggers: two indicate high temperatures and one more about bad SMART.
