I created a script to monitor uptime on a number of machines. It's rough, ugly,
inefficient, and I will get laughed at, but it works. Here it is:
#!/bin/bash
ticks=$(snmpwalk -v 1 -c public 10.0.0.1 hrSystemUptime.0 | awk '{ print $5 }'
)
echo "$ticks"
Now, this script works and populates data for Windows 7, Ubuntu, FreeBSD, etc.
However, MRTG WILL NOT populate the data returned from this script from a
CentOS machine. I have gone through and verified everything I can possibly
think of. When run, the script itself returns the proper data. The config files
match perfectly with the other working machine with the exception of the host
data of course. To my knowledge, all it needs is a number to graph. The script
returns a number, why won't it graph?!
