<p class="MsoNormal">Is there documentation for the format of error messages nginx posted to error_log?<o:p></o:p></p>
<p class="MsoNormal">Specifically, following the level in square brackets are two numbers separated by ‘#’; what do these represent?<o:p></o:p></p>
<p class="MsoNormal">For instance, the message on the page <a href="https://docs.nginx.com/nginx-ingress-controller/configuration/ingress-resources/advanced-configuration-with-snippets/">
<span style="color:blue">Advanced Configuration with Snippets | NGINX Ingress Controller</span></a> begins with “[emerg] 31:31:”
<o:p></o:p></p>
<p class="MsoNormal">Why I’m asking is for purposes of documentation; a system using nginx routes these messages to syslog; the design document for the module responsible for publishing the messages gives the format and examples. The example for nginx errors
begins:<o:p></o:p></p>
