Hi @jcorcorans I haven't discovered any great way to parse the chef-client.log

A few things that can help

1) look for the log_level when it isn't INFO/WARN

[2025-02-24T19:06:07+00:00] FATAL: Please provide the contents of the stacktrace.out file if you file a bug report

2) for log rotate, I see we have directives in /etc/logrotate.d/chef-cilent

"/var/log/chef/client.log" { weekly rotate 12 compress postrotate systemctl reload chef-client.service >/dev/null || : endscript }

3) and if you have a number of servers and you are running chef a lot and want to know when to truly spend time debugging since we find a chef operation can fail due to timeout or load, you check over a time period and see if in the end things are running okay.

So we have something like this: if after 3 times chef run is still not good then investigate

idx=your_index sourcetype=chef:client ("FATAL: Chef::Exceptions::ChildConvergeError:" OR "FATAL: Chef::Exceptions::ValidationFailed" OR "Chef run process exited unsuccessfully" OR "INFO: Chef Run complete" OR "INFO: Report handlers complete") | eval chef_status=if(searchmatch("ERROR") OR searchmatch("FATAL"), "failed", "succeeded") | stats count(eval(chef_status="failed")) AS num_failed, count(eval(chef_status="succeeded")) AS num_succeeded,latest(chef_status) as latest_chef_status by host | search num_failed > 3 AND latest_chef_status!="succeede

To monitor the logs, a simple monitoring stanza in your inputs

[monitor:///var/log/chef/client.log] sourcetype=yourchefsourcetype index=your_index
