      We have a case whereby a template used for SMART monitoring covers both HDD and SSD hosts. The items in the template are of type dependant. In some cases, there are items that can't be evaluated, as the value cannot be found (for example Percentage Lifetime Used is only available on SSD's not HDD's.

      Each time the item is processed, an error is logged in the Zabbix Server log file, which dumps out the entire output, as follows:-

      12689:20180510:114743.525 error reason for "host1-example:uHDD["/dev/bus/0 -d sat+megaraid,0",202]" changed: Item preprocessing step #1 failed: cannot perform regular expression match on value "smartctl 6.4 2014-10-07 r4002 [x86_64-linux-3.16.0-5-amd64] (local build)

      We are monitoring thousands of hosts with Zabbix, and are seeing the log files hit anything around 5G. Log rotate does take care of this eventually.

      Ideas:-

       * Limit the output of a failed item preprocessing to X characters

       * Have the ability to "mute" item errors, either per item or a global option.

       

      Thanks as always!
