Yes cut & paste is a lot better than doing it all from scratch. SNPMWALK
for me, thank you! Here's the data collection part:
/usr/local/mrtg-2.9.4/bin/cfgmaker --global 'workdir:
/home/httpd/html/mrtg/servername' --ifref=descr --global 'options[_]:
growright,bits' snmp-name-here@xxxxxxxxxxxxxxxxxxxxxx
Add this to the config:
PathAdd: /usr/local/bin/rrdtool/bin/
LibAdd: /usr/local/bin/rrdtool/perl-shared/
LogFormat: rrdtool
For the actual graphing I use a script called 14all.cgi.
This is a processor info script I use, split by user & total. System time
can be calculated easily via subtraction by the user.
Title[servername-servicename]: processor stats for servername.goes.here
Target[servername-servicename]: `/usr/local/bin/nc -w 5 server.ip.goes.here
port`
PageTop[servername-servicename]: <H1>Processor stats</H1>
MaxBytes[servername-servicename]: 100
Unscaled[servername-servicename]: ymwd
Options[servername-servicename]: growright,nopercent
LegendI[servername-servicename]: user:
LegendO[servername-servicename]: total:
Ylegend[servername-servicename]: %
ShortLegend[servername-servicename]: %
Legend1[servername-servicename]: Time spent in user mode
Legend2[servername-servicename]: Time spent in user mode + time spent in
system mode
Legend3[servername-servicename]: Maximum occurance of time spent in user
mode
Legend4[servername-servicename]: Maximum occurance of (time spent in user
mode + time spent in system mode)
<script that runs under xinetd on 'port' to get processor info>
#!/bin/bash
</proc/stat /bin/awk '
/cpu / {
print $2+$3
print $2+$3+$4
}
'
/usr/bin/uptime
/bin/hostname
</etc/xinetd/cpuload> (or whatever)
# CPU info reported to mrtg
service cpuload
{
socket_type = stream
flags = REUSE NAMEINARGS
wait = no
protocol = tcp
port = port#here
user = root
server = /usr/sbin/tcpd
server_args = /usr/local/bin/cpuload
only_from = your.network.goes.here/cidr
bind = your.private.ip.here
disable = no
}
Etc.! Don't forget tcp-wrappers.
