iControl web app to generate data for Cacti graphing

I'd like to see Agent/Server/BigIP side resource usage for equivalent tasks... I'm not certain it would be very easy though...

 

 

And Derek, yes cycles DO matter. Just ask your data centre manager whether he cares if you can run your monitoring app on a 16-way i7 with 64GB of memory or a 2 way 1U box with 4GB... if he's anything like ANY of the DC managers I've ever worked with, he'll care a LOT. Because it costs him an absolute truckload of money to provision rackspace and power to these puppies. Now you may have a DC next to your own private nuclear power station, but when when they run out of power in the DC and you have to re-negotiate with the owners for more current, you'll find he's pretty receptive to ANYTHING that will lighten the load... (Been there, done that).

 

 

Cycles on both the F5 and the manager matter a lot... Just in different ways... if you consume 20% of your F5 just to monitor it, then that's 20% of the cash you spent to buy it that isn't being used to service customers.

 

 

Oh. Just in case you think I'm anti iControl and pro SNMP... I'm not... There's a place for both... Management of the F5... That's iControl. Polling for stats, that's SNMP (I've used iControl for this, it is a lot heavier but I'd still like to see a proper set of testing done. I may have to think for a bit how we could profile both the iControl server and the SNMP daemon on an F5 to discover how hard each has to work to gather say full stats on 100 VS's, 200 pools and associated profiles.
