I would like to create a service whose job is to monitor other services that are running within the same process, and then report basic information like health or service dependencies. I'm having trouble figuring out the best way for my monitoring service to access detailed information about the other services without having to have each service publish its metadata or expose some custom endpoint the monitoring service can communicate with. If I load the configuration and read through it I can get most of the way there but this approach has a few weaknesses:

  • Getting the absolute URI for each endpoint can be difficult, especially when using IIS hosting or fileless activation.
  • Any configuration that was done programmatically would not be able to be read by the monitoring service

What I'd like to be able to do is to somehow access the ServiceDescription to get all the information I need about each ServiceHost, without requiring any work on the part of the service designer to give it to me. Is something like this possible?

  • It would help a bit if you showed how you're configuring your hosting environment to get the current services to run in the same process. – Sixto Saez Apr 18 '12 at 14:52
  • Maybe my terminology isn't quite right. By "in the same process" I mean services configured to be hosted inside the same windows service or web application. Each of the services you would define in 'system.serviceModel/services'. – mclark1129 Apr 18 '12 at 15:13

One alternative would be to use WCF's built-in health monitoring and performance monitoring capabilities. This works at the individual service level though.

If you've checked Channs links and are convinced you need to roll your own health monitoring infrastructure, you'll probably need to either derive from ServiceHost or go all out and derive from ServiceHostFactoryBase or possibly do both depending on what you need to implement. They'll give you access to the ServiceDescription instance for each service as it is spun up.
