[Devmon] devmon hobbit and redhat

[Dmitry S. M. <dm...@at...>]

Hi,

I'm not subscribed to the list so CC in reply is highly appreciated.

I'm trying to get things going with hobbit+devmon monitoring RedHat machines 
running snmpd for system load etc. However produced graps seem rather strange 
(big spikes all of suddent and then "silence" -> 0 load) using second tool to 
monitor same activities I see much more detailed graph which only remotely 
resembles what devmon + hobbit produced. Finally I've managed to mangle 
configs to the point where it apparently won't even store data in RRD. Is 
there a detailed HOWTO on subject or maybe somebody is willing to share 
templates/configs with me?

My latest "improvement" got me to the point where I've got bars on the graph 
drawn for every other 5 minutes (18:25-18:30, 18:40-18:45).
