Log handler in Zabbix?

Question

linux

The essence of the problem is this.
It is necessary to build graphs for events in the logs.
Tried to do it through a script with tail -f | grep
If one value was found, then zabbix_sender sent the key with value 1, if another value, then with value 0.
Added scripts to autoload, but after some time (always different) they stop sending data to Zabbix.
Tell me, how can I process logs with sending values ​​to Zabbix? Through the built-in monitoring of the logs, not what is needed comes out, because. numeric values ​​are needed to build a graph, but they are not in the logs, but only strings.

Answer 1

Zabbix can extract the necessary values ​​from log lines using regular expressions.
