Read timed out error in SAP PI Monitoring

Updated May 22, 2018

Hello SAP Experts,

I am facing grey metrics for channels in PI Monitoring UI. While reviewing the DAA (Diagnostics Agent) logs assigned to the PI system, I am getting the following error:

Time <timestamp>
Severity Error
Location com.sap.smd.e2emai
Text [MAIJobObserver] ERROR occurred for metric collection <MetricCollection>[com.sap.smd.nw.mai.pi.ChannelMonCollectorBuilder].

Please follow steps below in order to re-generate this issue:

First navigate to Agent Servlet via: https://<HOST>:<PORT>/tc~smd~agent~application~e2emai/servlet/MAI
Now please select the DAA assigned to the PI system.
Now when you go to "Show Last Collection Errors" tab. The error mentioned above will appear.

Please help me to resolve this issue

The error you are facing occurred because the read timeout parameter has too small value.
Please follow the steps below in order to resolve this issue:
- First, navigate to Agent Administration: https://<HOST>:<PORT>/webdynpro/dispatcher/sap.com/tc~smd~server~agent~admin/SMDAgentAdminApplication?sap-language=EN
- Then choose Application Configuration tab.
- Now please choose "Select Scope" drop-down, the agent on which PI system is running.
- Then please select agent application com.sap.smd.agent.application.e2emai.pi
- Edit -> Write in "Custom Value" column a higher value for collector.grmg.http.read.timeout.ms (90000 ms aprox).
- Edit -> Write in "Custom Value" column a higher value for collector.simple.http.read.timeout.ms (90000 ms aprox).
- At last please save the changes and restart the DAA assigned to the PI system.
