Blue Matador’s agent (installed on your servers) maintains an active, open TCP connection over port 443 with our servers in the cloud. When the agent fails to respond to multiple successive heartbeats, the associated server is considered unresponsive.
Servers in auto-scaling groups are exempted from this recommendation as they automatically and regularly launch and terminate servers.
The root cause of the unresponsiveness could be:
You can be sure that unless this server was shut down intentionally, your application and users will suffer.
Restart the bluematador-agent service. If you’re unable to log into the affected server, restart the server.
Compare server vitals against deployments, configuration changes, infrastructure changes, user logins, and automated remediation. For every inflection point, identify the root cause. If one seems out of place, investigate and remedy as appropriate.
