Service Monitoring Service (SVCMON)

The Service Monitoring Service (SVCMON) is a specialized current value service that provides a method to monitor many system, service, and site statistics. The SVCMON can be used to perform service health checks, check ping times, monitor disk utilization, software and operating system version numbers, memory usage and ping times. Attributes of specific services can also be monitored, such as VHS database utilization and percent full, pending GNS notifications, total points and maximum points for current value services, and Address Resolution Service license counts.

Additionally, the SVCMON supports a defined set of calculation types. Point tags can be added to monitor deltas and rate changes. For point tags that represent file sizes, items can be scaled. The maximum point count for the SVCMON is 500,000 points.

For example, you can create SVCMON tags to monitor:

1. the size of the Value History Service database (in bytes)
2. a scaled value of the database size (in bytes, kilobytes, megabytes, or gigabytes)
3. the rate the file is growing (in milliseconds, seconds, minutes, hours, or days)
4. the delta (percentage difference) of the file size between updates

Each SVCMON point tag is associated with a timer. The timer determines the update rate of the point tag. Any number of timers can be added. The maximum refresh rate is 1 second.

Info items are the SVCMON tags. SVCMON tags are based on a set of SVCMON-specific system UDCs and CygNet services or sites. Each UDC has an associated template. As point tags are created for a UDC, the settings of the template are applied to the point tag. A template can be changed, and the changes applied to all point tags that use the UDC. All SVCMON UDCs begin with the letters SVM. See CygNet ServiceMon Administration utility for a complete listing of SVCMON UDCs.

SVCMON point tags are just like any other point tag in the CygNet system in that they can be configured to report values to the Value History Service and to trigger alarms and notifications.
