Hi @Malla Reddy.Byreddy,

Take a look at this article on "No data in the Metric Browser" -- it could be that your agent isn't properly configured, or the time range is set as such that you aren't seeing data for that particular range.

Did you check the logs? What error do you see?

i didnnt see any mentioned error except as below,

[#|2018-01-25T13:49:10.106-0800|INFO|glassfish 4.1|com.appdynamics.metadata.cache.entitycache.BaseMetadataCache|_ThreadID=131;_ThreadName=http-listener-2(10);_TimeMillis=1516916950106;_LevelValue=800;|ID000062 Metric 280:btm|application summary|errors per minute not found|#]

This look like controller server.log.

I am asking about the machine agent logs found under <machine_agent_home>\logs\machine-agent.log

Are you sure you started machine agent with proper user who has access to filesystems on the server?

Looks like you are trying to monitor home filesystem of all the users, only root or super admin has access to all those file systems.

[Malla Reddy.Byreddy]

Even in that case I should get some data in metric browser right  ?

[gurmitsa]

Not really. What other errors do you see in the logs?

can you grep "missing ip" in your log?

[Malla Reddy.Byreddy]

No match for "missing ip " in logs
