The Error Log - Error Count alarm counts the total number of entries that were filtered from the SQL Server Error Log during the last sampling period according to the match/ignore filtering rules set by Configure Error Log Entries.
When the alarm is raised use the SQL Server | Error Log drilldown to view the errors.
Note: Use the Spotlight Client Configure | Error Log Entries to define and edit the alert rules that Spotlight scans the SQL Server Error Log for. Spotlight scans the error logs at the configured frequency. If you make changes to the alert rules it may take some time for changes to take effect. You can change how often Spotlight scans the error log in the Spotlight Client at Configure | Scheduling.
