Hello, we are looking to have the number of TCP connections on a particular process in order to put an alert when it exceeds the number of user connections For example On port 2020 the process has a connection limit of 500 people Is there an industrial way to put an alert on Dynatrace

Regards

There is no metric for this out of the box. You can&nbsp;[use a custom OneAgent Extension](https://www.dynatrace.com/support/help/extend-dynatrace/extensions/oneagent-extensions/oneagent-extensions-hands-on)&nbsp;to add the metric and specify thresholds.
