Drill Down Facility in APAN

[Carroll, Jim P [Contractor]]

I spent some time (once again; definitely not my first time) browsing the various RRD solutions.  And yes, I agree that picking from one of the canned RRD solutions would save many gyrations attempting to make Nagios do this.

I ask that you consider the following and give me some idea of what I might be up against:

- as near as I can tell, just about all of the RRDworld solutions either look at the local host, or require that you use SNMP (cacti is possibly the one exception, allowing you to leverage scripts... however, it also requires MySQL)

- all roads lead to SNMP

- Nagios already queries the various services on the various hosts; if an RRDworld type solution cannot leverage the data already collected by Nagios, that means either a) leveraging the Nagios plugins, b) writing a custom script, or c) leveraging SNMP

- all roads lead to SNMP

- one of my peers has expressed concern over the security (or lack thereof) in SNMP; I'd be curious how to 'lock down' SNMP; I'm already aware of the need to change the read-only community name, and I'd like to disable the read-write community altogether; I'd also like to be able to say, "unless the query is originating from an authorized IP (or subnet), drop the packet on the floor"; I'd be interested in hearing about any other ways to tighten things up more, without inadvertently causing myself a major headache

- all roads lead to SNMP, provided this hurdle can be overcome

Assuming I can meet the above objectives, my sense is that I'll have a fairly large project ahead of me (correct me if I'm wrong).  Target hosts include:  Solaris8, RH Linux and Win2k.

Another big question is, which RRDworld tool to implement?

Based on all the above, all should feel free to send me (on the list) your comments and recommendations.  :)
