Sumber: http://www.it-slav.net/blogs/2009/02/05/install-and-configure-snmp-on-ubuntu/


This guide describe howto install and configure SNMP on Ubuntu.

In an earlier article I have described howto set it up on RHES or CentOS, it is slightly different in Ubuntu. 


==Installation==

apt-get install snmpd


Configuration

Move existing /etc/snmp/snmpd.conf configuration file to /etc/snmp/snmpd.conf.org 

mv /etc/snmp/snmpd.conf  /etc/snmp/snmpd.conf.org

Create a new /etc/snmp/snmpd.conf file: 

rocommunity  public
syslocation  "PDC, Peters DataCenter"
syscontact  peter@it-slav.net

Make snmpd use the newly created file and make it listen to all interfaces:

Edit /etc/default/snmpd

Change from: 

# snmpd options (use syslog, close stdin/out/err).
SNMPDOPTS='-Lsd -Lf /dev/null -u snmp -I -smux -p /var/run/snmpd.pid 127.0.0.1'

To: 

# snmpd options (use syslog, close stdin/out/err).
#SNMPDOPTS='-Lsd -Lf /dev/null -u snmp -I -smux -p /var/run/snmpd.pid 127.0.0.1'
SNMPDOPTS='-Lsd -Lf /dev/null -u snmp -I -smux -p /var/run/snmpd.pid -c /etc/snmp/snmpd.conf'

and restart snmpd 

/etc/init.d/snmpd restart



Test

Do a snmpwalk from another host against your newly configured host. 

[root@op5 ~]# snmpwalk -v 1 -c public -O e ibsen
SNMPv2-MIB::sysDescr.0 = STRING: Linux ibsen 2.6.27-9-generic #1 SMP Thu Nov 20 21:57:00 UTC 2008 i686
SNMPv2-MIB::sysObjectID.0 = OID: NET-SNMP-MIB::netSnmpAgentOIDs.10
DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (68869) 0:11:28.69
SNMPv2-MIB::sysContact.0 = STRING: peter@it-slav.net
SNMPv2-MIB::sysName.0 = STRING: ibsen
SNMPv2-MIB::sysLocation.0 = STRING: "PDC, Peters DataCenter"
SNMPv2-MIB::sysORLastChange.0 = Timeticks: (1) 0:00:00.01
SNMPv2-MIB::sysORID.1 = OID: SNMP-FRAMEWORK-MIB::snmpFrameworkMIBCompliance
SNMPv2-MIB::sysORID.2 = OID: SNMP-MPD-MIB::snmpMPDCompliance
SNMPv2-MIB::sysORID.3 = OID: SNMP-USER-BASED-SM-MIB::usmMIBCompliance
SNMPv2-MIB::sysORID.4 = OID: SNMPv2-MIB::snmpMIB
SNMPv2-MIB::sysORID.5 = OID: TCP-MIB::tcpMIB
SNMPv2-MIB::sysORID.6 = OID: IP-MIB::ip

Yes it works!!


4. Monitor example

Below is an example of how it looks using op5 Monitor a Nagios based Enterprise Monitor solution.

5. Useful links 

   op5 Statistics, a cacti based graph tool
   op5 Monitor, an Enterprise Class Monitoring system based on Nagios
   Net-SNMP, an open source implementation of SNMP
   Cacti, an open source graph tool
   Nagios, the number 1 monitor tool
