Collector is in Deactivated state and fails to restart

Problem:

When attempting to restart offline Collectors the restart fails and the following messages are found within the /<sumoHome>/logs/collector.log file.

Resolution:

These messages may be seen when a Sumo Logic Free account has gone over the ingest or storage usage limits and Collection has been temporarily deactivated. Once in this state Collectors will be unable to be restarted until ingest or storage quota has fallen back below the allowed limits for this account level.

Sumo Logic free accounts have the following ingest and storage limits. 

• Ingest: Average of 500MB per day, up to 4 GB total over a 7 day period.
• Storage: 4 GB Total

The current usage volume for ingest and storage can be viewed within the Administration > Account page. 

Deactivation due to Ingest Limits

If a deactivation was due to high ingest volume Collection will only be re-enabled once ingest quota becomes available. Depending on the amount of data recently uploaded it could take between 1 to 7 days for the quota to become available. 

Deactivation due to Storage Limits

If a deactivation was due to high storage volume Collection will only be re-enabled once storage becomes available. The time it may take for storage to become available will depend on the retention period set on the partitions or general index within the account. Retention periods may be adjusted (ie. lowered) by:

1. Going to the Manage Data > Settings page of your account.
2. Open the Partitions tab of the Settings page. 
3. Select the hamburger icon to the far right of a selected Partition and then select Edit Retention Period.
4.  Enter a new retention period for the index.

Once the retention period is updated any data received into the index prior to the new retention period will be purged from Sumo Logic and storage quota will start to become available within the account.
