Hi Well I want to configure Net-snmp for MRTG. But I wana know how to configure com2sec rule in snmpd.conf file for so many different Networks which are configured on routers switches and nodes with the different ranges of network classes.Like /24, /30, /26 ,/28 with the different ranges.And also wana know how to configure MRTG for cpu , disk and memory usage.

Make sure snmpd configured.

Create directory for mrtg grap in Apache webroot:

Code:

mkdir /var/www/mrtg

Run cfgmaker:

Code:

cfgmaker  \
--output=/etc/mrtg/traffic.cfg \
--ifdesc=ip \
--ifref=descr \
--global "WorkDir: /var/www/mrtg" \
--global "Options[_]: bits,growright" \
  public@localhost

Create /etc/mrtg/cpu.cfg and append config code:

Code:

WorkDir: /var/www/mrtg
LoadMIBs: /usr/share/snmp/mibs/UCD-SNMP-MIB.txt
Target[localhost.cpu]:ssCpuRawUser.0&ssCpuRawUser.0:public@127.0.0.1+ ssCpuRawSystem.0&ssCpuRawSystem.0:public@127.0.0.1+ ssCpuRawNice.0&ssCpuRawNice.0:public@127.0.0.1
RouterUptime[localhost.cpu]: public@127.0.0.1
MaxBytes[localhost.cpu]: 100
Title[localhost.cpu]: CPU Load
PageTop[localhost.cpu]: <H1>Active CPU Load %</H1>
Unscaled[localhost.cpu]: ymwd
ShortLegend[localhost.cpu]: %
YLegend[localhost.cpu]: CPU Utilization
Legend1[localhost.cpu]: Active CPU in % (Load)
Legend2[localhost.cpu]:
Legend3[localhost.cpu]:
Legend4[localhost.cpu]:
LegendI[localhost.cpu]:  Active
LegendO[localhost.cpu]:
Options[localhost.cpu]: growright,nopercent

Create /etc/mrtg/memory.cfg and append config code:

Code:

LoadMIBs: /usr/share/snmp/mibs/HOST-RESOURCES-MIB.txt
Target[localhost.mem]: .1.3.6.1.4.1.2021.4.6.0&.1.3.6.1.4.1.2021.4.6.0:public@localhost
PageTop[localhost.mem]: <H1>Free Memory</H1>
WorkDir: /var/www/mrtg
Options[localhost.mem]: nopercent,growright,gauge,noinfo
Title[localhost.mem]: Free Memory
MaxBytes[localhost.mem]: 1000000
kMG[localhost.mem]: k,M,G,T,P,X
YLegend[localhost.mem]: bytes
ShortLegend[localhost.mem]: bytes
LegendI[localhost.mem]:  Free Memory:
LegendO[localhost.mem]:
Legend1[localhost.mem]: Free memory, not including swap, in bytes

Run mrtg -

Code:

env LANG=C /usr/bin/mrtg /etc/mrtg/cpu.cfg
env LANG=C /usr/bin/mrtg /etc/mrtg/memory.cfg
env LANG=C /usr/bin/mrtg /etc/mrtg/traffic.cfg

Run indexmaker

Code:

indexmaker --output=/var/www/mrtg \
--title="Server.Domain.Com MRTG" \
--sort=name \
--enumerate \
/etc/mrtg/traffic.cfg \
/etc/mrtg/cpu.cfg \
/etc/mrtg/memory.cfg

Setup cron job:

Code:

crontab -e

Append code:

Code:

*/5 * * * * env LANG=C /usr/bin/mrtg /etc/mrtg/cpu.cfg
*/5 * * * * env LANG=C /usr/bin/mrtg /etc/mrtg/memory.cfg
*/5 * * * * env LANG=C /usr/bin/mrtg /etc/mrtg/traffic.cfg

Well I ran cfgmaker to create mrtg.cfg file but it gives me an SNMP Error: no response received.The command is as below #cfgmaker --global "workdir: usr/local/www/mrtg/node-01" -ifref=ip --output /usr/local /www/mrtg/node-01/node-01-mrtg.cfg --global 'options[_]: growright,bits' public@node-01 ERROR is as below SNMP Error: no response received SNMPv1_Session (remote host: "node-01" [192.168.10.8].161) community: "endai-snmp" request ID: -736885146 PDU bufsize: 8000 bytes timeout: 2s retries: 5 backoff: 1) at /usr/local/lib/perl5/site_perl/5.8.8/SNMP_util.pm line 627 SNMPWALK Problem for 1.3.6.1.2.1.1 on public@node-01::::::v4only at /usr/local/bin/cfgmaker line 918 WARNING: Skipping public@node-01: as no info could be retrieved ################################################## ### So where could be the problem with this setup and I have also got so many ranges of subnets and network so how to define com2sec source in snmpd.conf file.
