vRealize Operation Endpoint Agent Unable to register error

When you install a vRealize Operation Endpoint Agent and then check status of Agent You will see similar message on screen: “Agent not yet setup”

You can check status of agent if you browse by CMD (run as administrator) the agent’s folder (default on Windows it is “C:\ep-agent\”) and go “bin” folder.

There are two files. In Windows environment you can select “ep-agent.bat” and write after that “status” command as you can see in picture below.

Start and stop agent or restart the agent follow the commands below:

“c:\ep-agent\bin\ep-agent.bat stop”
“c:\ep-agent\bin\ep-agent.bat start”

or

“c:\ep-agent\bin\ep-agent.bat restart”

End of process you will see this message: “Unable to register the agent due to server error.”

Login to Node (in this case we use Remote Collector) by SSH and go
“cd /storage/log/vcops/log/adapters/EndPointAdapter/”

In this folder you can find logs of End Point Adapter: EndPointAdapter_XXX.log

If you don’t confort with command line, you can find this log on vRealize Operation UI under “Administration/Support/Logs”
Open Node or Remote collector and browse this path: “Collector/Adapters/EndPointAdapters/EndPointAdapter_148.log”
Double click the log file and top of the logs click narrow next “Word Wrap”
Fill the “Search For” option by failed or ERROR text and hit enter.

Fortunately the solution is really simple, just enable Operating Systems solution in vRealize Operation 🙂
