Detecting Connection Timeouts

Install metric...

Metrics install automatically if you have SQL Monitor installed.

If you are using Redgate’s SQL Server monitoring tool, SQL Monitor, you can instantly install and run this metric on your servers.

Connection timeouts can be difficult to troubleshoot. It’s sometimes not even apparent that a timeout has occurred. However, the connectivity_ring_buffer_recorded Extended Event can show that this has happened. This is a debug event within Extended Events, so some caution is necessary in its use. Microsoft can change the debug events without warning.

You can use SQL Monitor to see that a connection had a timeout. In order to then troubleshoot the issue, you will need to look at the information captured by the Extended Event session defined below:
