I set up telegraf to use some custom grok patterns. One of the pattern files is the standard logstash grok patterns. The documentation suggests that the logstash patterns will work however I have noticed an error in the telegraf.log as follows:
2019-03-08T16:05:24Z E! [inputs.tail]: Error in plugin: E! Malformed log line in /motescan/scannet03/log/ag_history.log: [[Mar 08 2019, 16:05:22.781: rdata] Remote uploader version: 2.1.3], Error: error parsing regexp: invalid or unsupported Perl syntax:
The offending part of the grok statement appears to be ‘(?>’ which is an ‘atomic group’. The logstash grok statements use this.
Has anyone else encountered this issue?
I am running telegraf 1.10.0
