[Leandro Roggerone]

  Hi , My name is leo , this is the first time im going to post my 
questions, im working on an isp and I need to solve some monitoring 
issues on our core. I have read two guides about nagios but I still have 
some problems getting some plugins to work.
So here they are:

I need to monitor some especific proces on local and remote linux machines:
Eg:

I need like to know if named is running in my local machine.
I need to know if my shaper stoped working on a remote machine.
I need to meassure the traffic on an especific interface and to set an 
alarm when it fals or exced some trigger lever.
I would like to monitor the temperature of my hardware. (cisco and linux 
machines).

These are issues that i can not solve yet, any ideas ??? Ok, Ill be 
waiting for some help, bye.LEO.
