Hi Rajesh. There are many tools you can use, for instance Metis, Dynatrace, Datadog, AppDynamics, or Jaeger. Mind that some of these overfocus on capturing signals and lack reasoning and troubleshooting. See this article to learn more: https://www.metisdata.io/blog/all-your-monitoring-solutions-are-just-wrong

The easiest is to take OpenTelemetry and wire it up in your infrastructure. I don't know what your tech stack is, but most applications should handle it pretty well.
