Devo offers a generic collector monitoring activeboard, which allows to notice the following data by using the devo.collectors.out as data source:

• Number of collectors active / failing.

• Collectors that stoped sending data in the last hour.

• Errors & Warnings.

• General activity and types of messages.

• Errors in credentials (401/403)

• API limits (429)

• Server errors (500, 501, 503)

To query SQS messages successfully processed by SQS collectors, use

from devo.collectors.out 
where toktains(msg,"Acked message receiptHandle"), 
toktains(collector_image,"aws_sqs_if") 
group every 5m by collector_name, job_id 
select count() as messages_successfully_processed

The number of SQS messages may be more or less than the number of events sent to Devo. An inactivity alert that keeps track of job_id :will inform you if messages are not being processed.

Monitoring with AWS

CloudWatch allows you to create alarms for:

• Messages sent below threshold, which can occur if data is no longer entering the S3 bucket.

• Number of messages visible is too high, which can occur if the SQS collector was turned off.
