[Xymon] Where to find the latest hostdata (or: How to monitor one process on two servers)?

[Ward, Martin]

Hi all,

I have a pair of servers that run Veritas Cluster Software and they have a number of different processes that they run in turn. Simply put it means that there is a process that will be running on one or another of the two servers and at any given time I will not know which server it runs on. The important thing for me is that it is running, so I set about creating a monitor that will check for this.

I can't have something that runs on the client since I won't know which client the process runs on but it struck me that the server always has an up to date process list, so I could simply read the hostdata file for the two servers, rip out the process list, concatenate the two and search for the specific process name, simple!

This is a brilliant idea that would work if only I had access to the up to date client data. It seems that the data stored in the hostdata directory only changes when a status for that server changes to an alert state (according to the xymond_hostdata web page) so if the process switches to a different machine but nothing actually changes the alert status of the client, the latest host data is not stored in the hostdata/ subdirectory.

I know that the latest host data is stored somewhere because I can see it in the web browser. Does anyone know where this up to date host data is kept such that I can utilise the information in it?

Failing that do you have any other suggestions, recommendations or scripts lying around that will enable me to look for a process across more than one server?
