Re: An internal error occurred .* = 1 in sitescope 11.20
I know the reply is very late, but we also had the exact same issue for the past couple of days. The short answer is this:
The "An internal error occurred" portion of the Log Event Checker is a bit confusing, as what the monitor checks for isn't actually "An internal error occurred", but rather just "internal error". Where does it check this? The status of any monitor on your Sitescope instance.
That means that if a monitor isn't exceeding any thresholds, but where the status contains "internal error", the Log Event Checker will return an error for "An internal error occurred".
For some reason this isn't documented very well (if at all), so that's why I'm submitting this here in case anyone else stumbles onto the same issue.
Easy way to narrow down which monitor is problematic is to open the SiteScopeYYYY_MM_DD.log file, and doing a search for "internal error". Either amend, fix or delete that monitor, reset your Sitescope health check monitors, and the problem should be fixed.
