If you have received an Alert Email from Sumo Logic stating that an issue has been detected with a Scheduled Search, it might not be immediately apparent why your Scheduled Search has failed, and may even be suspended. The Scheduled Search referred to in the email may be one that has run for months without a problem, but now for some reason, it fails.
A Scheduled Search email Service Alert looks like this:
First, we recommend that you review the scheduled search. (Just click the link at the bottom of the email.) It could be that there's an easy-to-spot typo. Or perhaps an operator is being used improperly.
Why was my Scheduled Search suspended?
Scheduled Searches must run within the limits of a timeout period, which can be 20 minutes to an hour, depending on the time range set for the query. If, for some reason, a Scheduled Search cannot complete within the confines of the timeout period, such as connectivity problems or heavy load, the query will timeout and fail.
When a Scheduled Search query fails, Sumo Logic attempts to run the query again two more times, for a total of three tries. If all attempts fail, then an Alert Email is sent with a notification of the failure. The Scheduled Search is not run again until the next time it is scheduled to do so.
The next time the Scheduled Search runs, if it fails again after the three tries, then it is suspended. Another Alert Email is sent to notify you that the query has been suspended.
How long will the Scheduled Search be suspended?
The suspended state of the Scheduled Search lasts for four hours for non-daily searches (for example, searches recurring every 15 minutes, every 1 hour, etc.) and for up to an extra day for a daily search (two failed executions on two days and skips the third day).
Once the suspension period is over, the Scheduled Search will resume normal operation after four hours (for non-daily scheduled searches) or on the fourth day for a daily Scheduled Search.
How can I troubleshoot the failure?

Reactivate a Suspended Scheduled Search
If you would like to reactivate the Scheduled Search immediately without waiting for the suspension time out period, you you can edit the Scheduled Search and change the Run Frequency from Never back to the desired frequency. This will reactivate the Scheduled Search immediately. If the cause of the failure was temporary high load on the system, or some other connectivity issue, the Scheduled Search should run properly. But if the root cause is still unknown, it may fail again.
