SearchStax Cloud users sometimes report that the Deployment Overview server status says “Pulse Agent is down!”
This notice is not as alarming as it looks. Like a Heartbeat Alert, it means that the Pulse server at SearchStax has not heard from the Pulse Agent for several minutes. It does not necessarily mean that the server is down or that Solr service has been interrupted.
For one thing, when you restart Solr, the “Pulse Agent is Down” warning may be visible for a few minutes. Give it some time to come on line after the interruption.
When you see this warning, always check the CPU Monitoring graphs for the server to verify that the Solr service is still up. An interruption in service will appear as a gap in the graph.
If the warning persists, contact the SearchStax Support desk to get the service restarted.
Do not hesitate to contact the SearchStax Support Desk.
