@pixelcode I’m not sure I do understand your target setting correctly… With your grok pattern, the nohup:, Proxy starting and NAT type: (or any line not matching your pattern) will be ignored as the grok parser will not find a pattern match. You can see this when running Telegraf with --debug as this will also show when a line was not matched.
If you want additional information (e.g. the errors you mention), you need to provide additional grok-patterns for those lines. If you want to fill-in missing fields you should use the default processor or if you need more sophisticated logic you should look into the starlark processor which can also generate additional metrics etc…
