basic APM tool should monitor 1. Down time of the applications 2. Capture  the slow responses 3. Compare the response time metrics for before commit  vs after commit  4. Show distributed transactions (Call trace) 5. Alerting the security issues (Ex: If external library has the security issue then it should indicate the alert )  Good Nodejs  APM  tools https://www.appdynamics.com/ https://newrelic.com/ https://www.dynatrace.com/ https://opbeat.com/ https://www.instana.com/ https://traceview.solarwinds.com/ https://risingstack.com/
