Troubleshooting steps if a resource check is not added or when no alerts are received when a check fails
Common points to be remembered:
- Ensure the option Alert when a resource check fails is set to Yes in the associated server's threshold profile to trigger a TROUBLE alert for the configured check.
- Check if you have sufficient licensing. The total number of resource checks that can be added to a single resource check profile is 20.
URL Checks:
- For URL checks, the URL value must begin with either http:// or https://. This can be followed by the host name and optionally, the port [https://host:8080]./
File and Directory Checks:
- While configuring the File Access Check for Windows servers, ensure the Last Access Time Stamp is enabled. To enable it, update the key value to zero and then restart the server. Learn more.
- For Size checks, Last Modified checks, Content checks, Directory checks, File checks, specify the Absolute Path of the Directory. When mentioning the absolute path of the directory, use either '\' for Windows or '/' for Linux. Example: D:\folder\subfolder\ for Windows or /usr/lib/myfolder/ for Linux.
Event Log and Syslog Checks:
- For Event Log checks, ensure the correct event log name is entered. Go to Control Panel > Administrative Tools > Event Viewer > Windows Logs > double-click on the event > Event Properties > Log Name. Learn more.
- For Syslog checks, ensure the Source of the application is rightly mentioned. The source and name of the application are the same. To get the source, go to /var/log/syslog and copy-paste the source/name of the application that generates the system log.
For example: kernel, CRON, NetworkManager
