Trenger hjelp med MRTG

[Blaster2k]

Så jeg har installert MRGT og SNMPD for å vise trafikk på nettverkskortene og å vise CPU-bruk. Men den vil ikke vise CPU-loaden.

 

Slik ser det ut:

 

Jeg har gjort følgende

flatbox ~ # aptitude install mrtg snmpd

Svarte ja til "Make /etc/mrtg.cfg owned by and readable only by the MRTG user?"

 

flatbox ~ # mkdir /var/www/mrtg
flatbox ~ # nano /etc/mrtg.cfg

 

i mrtg.cfg gjorde jeg følgende:

 

# Global configuration
RunAsDaemon: yes
EnableIPv6: no
WorkDir: /var/www/mrtg
Options[_]: bits,growright
WriteExpires: Yes

Title[^]: Traffic Analysis for

 

I /etc/cron.d/mrtg har følgende jobb dukket opp. Noen mener at det er her problemet er:

*/5 *   * * *   root	if [ ! -d /var/lock/mrtg ]; then mkdir /var/lock/mrtg; fi; if [ -x /usr/bin/mrtg ] && [ -r /etc/mrtg.cfg ]; then env LANG=C /usr/bin/mrtg /etc/mrtg.cfg 2>&1 | tee -a /var/log/mrtg/mrtg.log; fi

 

flatbox ~ # nano /etc/snmp/snmpd.conf

 

i snmpd.conf gjorde jeg følgende:

#	   sec.name  source		  community
#com2sec paranoid  default		 public
com2sec readonly  default		 public
#com2sec readwrite default		 private

 

flatbox ~ # /etc/init.d/snmpd restart
cfgmaker public@localhost > /etc/mrtg.cfg
indexmaker /etc/mrtg.cfg > /var/www/mrtg/index.html

 

Hittil funker det som det skal. (Har jo ikke lagt inn CPU-grafen enda.

 

[cond]flatbox ~ # nano /etc/mrtg/cpu.cfg[/code]

Her legger jeg inn dette jeg hentet fra http://www.debianhelp.co.uk/mrtg.htm

WorkDir: /var/www/mrtg
LoadMIBs: /usr/share/snmp/mibs/UCD-SNMP-MIB.txt
Target[localhost.cpu]:ssCpuRawUser.0&ssCpuRawUser.0:[email protected]+ ssCpuRawSystem.0&ssCpuRawSystem.0:[email protected]+
ssCpuRawNice.0&ssCpuRawNice.0:[email protected]
RouterUptime[localhost.cpu]: [email protected]
MaxBytes[localhost.cpu]: 100

Legend2[localhost.cpu]:
Legend3[localhost.cpu]:
Legend4[localhost.cpu]:
LegendI[localhost.cpu]: Active
LegendO[localhost.cpu]:
Options[localhost.cpu]: growright,nopercent

 

flatbox ~ # nano /etc/cron.mrtg/cpu

Her legger jeg til:

#!/bin/sh
/usr/bin/mrtg /etc/mrtg/cpu.cfg

 

Lager en ny index-side som i tillegg til nettverkskort viser cpu:

flatbox ~ # /usr/bin/indexmaker --output=/var/www/mrtg/index.html \
> --title="System info: " \
> --sort=name \
> --enumerate \
> /etc/mrtg/cpu.cfg \
> /etc/mrtg.cfg

 

Legger til en cronjob ca slik det sto på debianhelp.co.uk

echo "*/5 * * * * /bin/run-parts /etc/cron.mrtg 1> /dev/null" >> /var/spool/cron/crontabs/root

 

Men det funker altså ikke. CPU-grafen dukker ikke opp.

 

MRTG-loggen sier følgende:

ERROR: CFG Error in "workdir", line 8: Working directory /var/www/mrtg does not exist

ERROR: CFG Error in "workdir", line 11: Working directory /var/www/mrtg does not exist

Håper noen kan hjelpe meg til å få cpu-grafen til å fungere.
