The SearchStax® Frequently Asked Questions page includes the following approved question and answer about our Apache Solr Cloud services.

System Load Average

A System Load Average alert is a Threshold Alert that notifies you by email when the Load of your Solr deployment exceeds a specified threshold for a period of some minutes. This creates an Incident in the Managed Solr Dashboard.

System Load Average alerts can result when the system is under heavy stress. Check the System Load graphs to evaluate the load.

Most Solr deployments can handle a load of 1 or 2. Some can handle more, but no system can handle a load of 800 as shown in the graph above.

Overloading is often associated with inappropriate indexing configurations. Consider adjusting your commit strategy to place less load on the system.

This situation can be relieved (not necessarily cured) by performing a rolling restart to clear the queues. Contact SearchStax Support if you need any help there.

If excessive system load becomes a frequent problem, the deployment might need an upgrade.
