KB-1989 Process sizing sheet is not populated in the Appian Health Check report

Symptoms

The process sizing sheet in the Appian Health Check report is not populated:

The following error is observed in the application server log:

ERROR com.appiancorp.tools.labs.collection.DataCollectionController - Problem running collector com.appiancorp.plugins.labs.collectors.ProcessModelSizingCollector 
...
Caused by: java.net.ConnectException: Connection refused

Additionally, the Summary tab shows the ProcessModelSizingCollector (plugin) under the Collection Errors section:

Cause

This error can occur if the processes execution engines are large in size and the Appian Health Check is unable to fetch the process information within two minutes.

Action

Archive or delete unnecessary processes in the environment to reduce the size of the process execution engines. If necessary, the sizing script can be used to manually obtain a report of the processes in the environment.

Note: The report generated by the sizing script is not as detailed as the report generated by the Appian Health Check.

Affected Versions

This article applies to all versions of Appian.
