Hi There,
I am using Zabbix to pull modbus data.
Every once in a while I get back a noisy result above 65000 which I would interpret as a failure to poll or other transmission error as none of our registers should ever return over 2000.
Since this is going over a cellular connection I am not surprised the data is a little messy.
I was thinking of using preprocessing on my Items to filter this out and possibly just returning a Not Supported value when anything rises above 65000.
I messed around a bit but couldn't hit the nail on the head with the right Parameters and Output on the Item Preprocessing configuration.
If anyone has a better idea for cleaning up noisy data please let me know.
If I am on the right path and you are well versed in configuring Preprocessing Items could you please send over your ideas for the regexp and output settings I would greatly appreciate it.
Thanks !
