MRTG

can i take mrtg data without using snmp in myclient, can i and how ?

but i have mrtg server with unix

Write a script to provide the data? SNMP is the easiest due to its simplicity… Failing that…

SSH into the box through your script, execute whatever command you want to monitor, sanitize the data you received, and send that to MRTG.

You can tell MRTG to run a script in it’s configuration file…
