Troubleshooting - URL Monitoring
The URL which the customer want to monitor should be accessible from the Machine where the APM is installed.
Check if the customer have configured any proxy for accessing the particular URL
If there are headers, request parameters needed they should be configured appropriately
Add user agent before adding, if required
Check for the response code returned while accessing the URL. We will expect Response code 200 by default for the every URL
Ask the customer enable 'Logging for URLs' and poll the monitor, so that response received will be saved as file under 'Debug_Info' folder. We can check for the response code and the response received for the particular URL
If the URL is not collecting data and if it is SSL configured ask for the version of the SSL used (SSLv3, TLSv1, TLSv1.2, etc)
If still the issue can't be predicted, then ask the customer to Poll the monitor or reproduce the issue 2 or 3 times and send us a SIF
If the URL the customer tries to monitor is a Public URL then we can try adding the same URL here and check the issue.
