In part 3 of our 'Understanding your graphs' mini-series, we talked about GitHub Enterprise Authentication graphs. In part 4, we're going to talk about GitHub Enterprise Application server and background job graphs.
The application servers section provides insight into the activity of GitHub Enterprise services which provide data to users, or integrations.
The Application request / response section looks at the rate of requests, how quickly those requests are responded to, and with what status they returned.
2xxsuccessful status codes will normally be the largest.
401Unauthorized codes will also be present in environments where API and Git over HTTP traffic is present, as initial requests from clients may not provide authentication headers.
500statuses indicate a potential issue with the GitHub Enterprise application, and should be investigated with support.
maint_git-servqueues are paused during GitHub Enterprise Backup Utilities snapshot runs. It is normal to see the number for this queue increase while a snapshot is in progress. The queue should then drain rather quickly once the snapshot run is complete.
When E-mail for notifications is enabled, this graph displays the length of the onboard
postfix mail queues.
High numbers of deferred E-mail messages may indicate a problem with the configured SMTP server, or failures in mail delivery to specific user E-mail addresses.
