What would you do with that data?
I'm looking at (and not very far along) picking up some application specific values, some of which only the current value matters. An rrd that looks like the 'physical memory' graph that opennms stores isn't all that interesting. I'd prefer some alternative where only the current value is stored but with an option to generate an event on a change if you wanted a history of transitions. > It might be easier to modify your data collection config to persist > the attributes that you're interested in as strings in addition to > their numeric form.

That would probably work but seems like considerably more overhead than necessary for something that doesn't change often or ever. -- Les Mikesell [EMAIL PROTECTED] ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
