Use the

Server

Statistics page to view the monitoring properties you configured or which are the default. Process Server collects engine statistics and then aggregates them by intervals. If desired, you can configure a threshold interval and an error/warning level for each of these properties. If you configure these settings, you will see additional signals displayed on this page, such as an eyeglass icon indicating a property is being watched.

During a collection interval, Process Server maintains statistics for each configured property value, including the maximum, average, and total count values. In addition, historical statistics are collected. Historical statistics include minimum and maximum values for the intervals being recorded. Statistics are collected in-memory.

In a clustered environment, the monitoring report’s top level is an aggregate of values from all engines in the cluster. Below the aggregate information is a report for each individual engine in the cluster. In a clustered environment, statistical information is relayed from one node to the next to allow for aggregation.

to clear statistics. For example, if you correct an error condition, you can reset the statistics collection starting with zero values to see if performance improves. Once all errors and warnings are cleared, the engine monitoring level is reset to Normal.

Monitoring indicators include the following:

Eyeglass icon
. Monitoring details for the property were configured on the Monitoring tab of the Configuration page. If no red or yellow highlights appear in the row, the collected statistics are within normal range.
Yellow highlight
. A warning-level condition occurred for the highlighted statistic during the threshold interval.
Red highlight
. An error-level condition occurred for the highlighted statistic during the threshold interval.

Monitoring Report

During each threshold interval, if an error or warning occurs, it is reported at the end of an evaluation period. For example, if your threshold interval is set to five minutes, and the evaluation frequency is set to five times per interval, the first trouble item may appear after one minute has elapsed, but will not be reported more than once per threshold interval. If competing threshold levels occur during same evaluation cycle, the highest severity is reported.

Each time you refresh your browser or open the Monitoring page, monitoring statistics are updated. The report, however, is updated only at the end of an evaluation period.

The list of trouble items shows the error/warning level, time, property name, and configuration details for each item reported. The following is an example of a report.
