Creating and Installing Message Handlers, Configuring Message Handlers, Message Server Overview, Message Server Configuration
A message handler is a custom coded COM server that implements Paul Bunyan’s IPBToMH interface and registers itself with the message server in order to receive and process log messages as they come in. The message handler interface is in standard terminology basically a hook or callback mechanism that we chose to implement using COM.
The use of message handlers is supported to allow log messages to be presented to custom code. This feature is typically used to create translation layers for putting messages into databases for regression testing or auditing purposes or for routing them to event handling products like Tivoli® or Opalis®. Event handling products in turn typically notify maintenance and support staff via email and paging, or automate exception handling by restarting services, deleting files, turning on water, etc.
