Troubleshooting Health Monitor messages

This article provides an overview of common  Health Monitor messages, and explains how to interpret and troubleshoot  them.

The xMatters Health Monitor sends error and warning messages to an email  address specified in the Global Configuration settings. This article identifies  some of the common Health Monitor messages, and explains how to resolve the  identified issues.

This article has been expanded and incorporated in the xMatters installation and administration guide.

Error Message:

The xMatters Health Monitor on node <NODE_NAME>  (<IP_ADDRESS>) has detected that the application has encountered an error:  Failed to process event for component "<COMPONENT_NAME>". Message payload  is of type:  com.invoqsystems.apex.component.communication.messages.<MESSAGE>. Consult  node logs for further details.

Explanation:

This error message usually results when a message is sent to a component  (i.e., a Device Engine) for processing, but no acknowledgment is ever received  indicating that the component was able to process the message. As this can  result from a number of situations, the only recourse is usually to examine the  Node logs.

Error Message:

The xMatters Health Monitor on node <NODE_NAME>  (<IP_ADDRESS>) has detected an error during message processing. This may  indicate that a non-redundant system component (node or device engine) was  stopped or has failed.

Explanation:

This error message usually results when the Node attempts to send a message  to a component (i.e., a Device Engine) for processing, but is unable to locate  the target component, or the target component does not exist. If you receive  this error message, you can try the following solutions:

  • Ensure that the target component exists, and is currently running. You can  view component status in the web user interface, on the Nodes and  Device Engines page.
  • Ensure that the target component is not overloaded; this error message can  also be generated if the Device Engine is attempting to process too many  messages.
