4.1 Displaying Metrics using System Insight
- Jenni Wallin
- Former user (Deleted)
System Insight displays metrics based on the filters determined with metrics and tags. The filter you create is determined by the metric that you want to display, and can be further refined by determining the tag name and tag value that you want to visualize. For example, if you want to visualize all of the MIMs in a specific workflow, your filter would be determined with mim.<workflow type>.<agent type>.<agent> without the addition of a tag on the metric.
The data included for a metric:
- A timestamp for when the metric was created or sampled
- Tags that carry metadata on the metric, for example, which workflow or pico the metric originated from
- Values for the actual data carried by the metric, for example, the number of udrs or the amount of data
For information on how to create a System Insight filter, see 4.1.1 Managing System Insight Filters. For information on the naming conventions in place for metrics, see 4.1.2 Metrics Naming Conventions.
System Metrics
The system metrics are host.compute, host.network, host.storage.iostats, host.storage.usage, host.storage.swap, pico.events, pico.jvm, pico.workflow,
service.akka.router.receiver
,
service.akka.router.sender
and
service.systeminsight.dispatcher
. The respective default fields in place for these metrics are listed below. You must create a System Insight profile to see these system metrics, see 2.2.34 systeminsight.
Note!
Depending on the filesystem access privileges that you have, the metrics might not be reported for some filesystems.
