Monitor Disk Fill Rate
Monitor the disk fill rate of your file system.
Monitor the amount of data that is being written per hour in your file system, as well as the amount of time remaining until your file system is full.
Use any tool that can graph disk space over time and give the disk fill rate for a system. The InterSystems IRIS Systems Alerting and Monitoring Application (SAM) provides this functionality. For more information on SAM, see the System Alerting and Monitoring Guide.
