Just for my collection of Grid Control messages, bugs and what so ever – for my effort (between my normal business) to get the ‘pie’ completely green and as few ‘critical’ errors as possible, which is sometimes a very depressive task:

After installing and configuring application server, the agent on that server started to sent messages like ‘The number of active connections is ..’  and a high number, too high for the metric.  But.. there are no connections yet on the system (as far as I know)!  Grid Control (OMS + agent) = 10.2.05, application server 10.1.2.0.2

Bug: 5717633 / 4458130. Note: 330819.1 —> EM/GRID CONTROL FALSELY REPORT ACTIVE HTTP CONNECTIONS WHEN KEEPALIVE=ON.

Solution:

1. “Change the value of the parameter KeepAlive to ‘Off’ in httpd.conf” —>  (nice! and what if this is not to be recommended for the application..).
2. “Restart all components using opmnctl stopall and then opmnctl startall” —> I tried to just stop and start the http-server and the agent, but that didn’t work.
3. “Check the current value of the active connections metric using the metric browser.” —>

What the heck is a metric browser, and how to use this…

Just try it out:

a. vi <AGENT_HOME>/sysman/config/emd.properties  (make a backup in advance..)

b. uncomment the following line:

#enableMetricBrowser=true

c. reload the agent through:

<AGENT_HOME>/bin/emctl reload agent

d. check the metric browser:

http|https://<agent_hostname>:<agent_port>/emd/browser/main

Example:

http://myServer.myDomain:3872/emd/browser/main
