port monitoring using sunmc
Does anyone know of a module for SunMC which can monitor whether servers are responding on specific ports ( e.g. port 25 ). Either a Sun or Halcyon module.
Also, does anyone know if a V125 would be powerful enough as a SunMC server. I've been told by a colleague that SunMC servers should have at least 2 CPUs. He installed it on a V210 with 1 CPU and said that it was very slow. The Sun documentation states a minimum of 1 GB memory, but doesn't say anything about CPU.
spec of V125 is 1x 1GHz CPU, 1Gb MEM and 73GB disk.
Thanks

I don't know about your first question but seems like someone must have done this before. I'll ask around...
The V125 - depending on number of systems monitored - may be just enough, though I agree it would benefit from a 2nd processor (especially when restarting the database, or in real time if monitoring many systems).
I still sometimes use (since it's frequently available) a 2x500 MHz system, and performance is bearable, so I'd say 1x1 GHz could be considered an unofficial minimum. I'll ask if there's any official guidance, and if so if it can make it into the documentation.

Look at the Service Availability Manager addon that ships with SunMC. It can monitor several services on common ports:

If that doesn't work, but you can test that port with a script (i.e. a wget/curl type transaction for a web page.. or even "netstat -an | grep <port>"... then you can have SunMC monitor it for you with ScriptRunner from Halcyon:

The question is: powerful enough for how many Agents? I''ve seen SunMC Servers running fine on Ultra 5/10s w/512MB of RAM and the performance was good enough for everyday use (but you wouldn't want to point 500 Agents at it).
