Why is my On-Premise Poller not getting registered?

Please find below the possible reasons for your On-Premise Poller not being registered:

• The most common cause is when your machine (where the agent is installed) might not be connected to the internet. Check if there are any connectivity issues with that particular machine.
  
• Another reason is when the proxy server details have not been specified during the installation process. Refer here to see how to configure proxy for Windows and Linux servers
  
• A third reason might be an incorrect API key. The On-Premise Poller is identified within the Site24x7 account only via the unique API key. 
  Note: Check for any extra spaces in the API key entered.   

Go to the installed folder and follow the below folder structure.

  <installed folder>\ conf\serveragent.config and check if the entry against CUSTOMERID and the API key you entered is the same.

The default directories for installing the On-Premise Poller are:

Windows: C:\Program Files(x86)\Site24x7OnPremisePoller

Linux: /opt/Site24x7OnPremisePoller
