Not sure how to ask this.
We offer a web-based service to our clients. This www server depends on several components (other servers, routers, switches, firewalls), all of which are set up as individual nodes in NPM. I can easily look at stats for any one on these nodes.
What I want to do it create a 'composite' of all of them so that I can track uptime/availablility of the www service, and be able to report on which component failed if the service is down.
I did set up an advanced alert which alerts if any of the nodes goes down, but this only provides down time info, not up time.
Am I making sense? If anyone has ideas on how to tackle this, I'd appreciate your input.
