Problem:  

In CEM when generating an SLA Report it shows message "Nothing found to display"

Changing the "Time Frame" from Today to Previous Week does show data.

 

Cause: 

The EM assigned to TIM Collection Service had not restarted due to socket connections being blocked by its java process after an incomplete shutdown 

In the Collector log: 

8/14/15 01:42:50.926 PM EST [ERROR] [main] [Manager.PostOfficeHub] Server failed to start listening for incoming default socket connections on port 6001 

In the MOM log:

8/14/15 02:20:00.537 PM EST [WARN] [Collector emtprd01-data@6001] [Manager.Cluster] Lost contact with the Introscope Enterprise Manager at emtprd01-data@6001

8/14/15 02:20:00.538 PM EST [DEBUG] [Collector emtprd01-data@6001] [Manager.Cluster] Creating default client socket factory. 

8/14/15 02:20:00.538 PM EST [DEBUG] [ClusterManager Async Executor] [Manager.JavaScriptCalculator] Removed Collector: emtprd01-data@6001 

8/14/15 02:20:00.549 PM EST [WARN] [Collector emtprd01-data@6001] [Manager.Cluster] Failed to re-connect to the Introscope Enterprise Manager at emtprd01-data@6001 (1) because: java.net.ConnectException: Connection refused 

 

Resolution: 

a. These commands run from a Linux terminal session can be used to check for a running EM process 

ps -ef|grep Introscope_Enterprise_Manager : checks for running Introscope EM java processes

netstat -nap|grep 6001|grep -i LISTEN  : shows any listening port for 6001 and the PID/program name holding it

b. To resolve the problem:

Stop the EM using command "EM_HOME/bin/EMCtrl.sh stop". After the message "Enterprise Manager stopped" is received check no Introscope java process is running using one of the above commands. If yes then kill it with "kill -9 <Process_ID>"

Start the EM by "EM_HOME/bin/EMCtrl.sh start". 

 

Additional Information: 

When TIM Collection EM is down on the Tims the stats & defect files will start to back up in the "/etc/wily/tim/data/out/" directories.
