Troubleshooting - URL Monitoring
Prerequisites:
- 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 yes, then the same proxy must be configured in the APM too
- If there are headers, request parameters needed they should be configured appropriately
- Add user agent before adding, if required
- Some times websites may be configured to behave differently for different browsers
Troubleshooting:
- Check for the response code returned while accessing the URL. We will expect Response code 200 by default for the every URL
- Refer the link for definitions of various response code: https://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html
- 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
Hint:
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.
