While we do not have direct API integration with RMM software, we have some different integration methods to help monitor and track how the backup clients are running.
Event Viewer Logging
The backup client's scheduler service and the backup engine will both write events into the Windows Event Viewer logs, specifically the Application log. The scheduler service will write Information level logs hourly to show it is running, and will also log when it triggers a Scheduled or Continuous backup. Similarly, the backup engine will write Information level "begin" and "end" messages with each backup. Additionally, any warning or error encountered during the backup process will be written as an equivalent level alert in Event Viewer, in addition to being written into the backup log.
If you use your RMM to track any incoming warnings and errors, you will get a congruent view of the issues a backup client is having, compared to the WSBU server dashboard and our BackupOps web console.
Related to tracking the Event Viewer, the backup client's scheduler service should always be running on a computer. If you want to more closely track the service than checking for its hourly "Active" messages in the Event Viewer, most RMM software can track the service state on a computer. If the scheduler service is not running for 10 minutes or more while the computer is running, that is a sign there may be an issue with the service on the target computer that needs to be addressed.
Email Reporting and Alerting
From the BackupOps web console, Reports & Alerts page, you can set up a daily scheduled "Admin Report" email that summarizes the latest backups from all of your backup clients, and if this is sent to an inbox read by an RMM, it can learn to parse the email and create tickets for computers having issues or that have not backed up recently.
Similarly, if you have the "No Data" and "No Connection" alerts enabled on the SMTP settings, and you have the RMM's email inbox as a "CC:" recipient, it will receive copies of all of the "No Data" and "No Connection" alerts that are sent out.
