Net-SNMP needs to be installed in your Linux boxes and be configured properly.
Installation:
SNMP can be installed via yum command on Redhat/CentOS or "zypper" command in Suse servers:
SNMP MIBs
With standard SNMP configuration, you don't get much details monitoring information you would like to have. So SNMP needs to be configured properly to produce all sort of SNMP MIBS.A standard Linux SNMP config produce following limited MIBs only if we snmpwalk on it:

Configuration
Following changes need to be done in a standard snmpd.conf file to make it produce all monitoring details.
# vim /etc/snmp/snmpd.conf
In the following section, comment out first 2 lines started with "view"and add the third line to your config file:
# Make at least snmpwalk -v 1 localhost -c public system fast again.
# name incl/excl subtree mask(optional)
--> comment out #view systemview included .1.3.6.1.2.1.1
--> comment out #view systemview included .1.3.6.1.2.1.25.1.1
--> Add view all included .1 80
Before:
view systemview included .1.3.6.1.2.1.1
view systemview included .1.3.6.1.2.1.25.1.1
After:
#view systemview included .1.3.6.1.2.1.1
#view systemview included .1.3.6.1.2.1.25.1.1
view all included .1 80
And in the following section, change the "systemview" to "all" in the line starts with "access":
####
# Finally, grant the group read-only access to the systemview view.
# group context sec.model sec.level prefix read write notif
--> access notConfigGroup "" any noauth exact all none none
Before:
access notConfigGroup "" any noauth exact systemview none none
After:
access notConfigGroup "" any noauth exact all none none
and finally restart the snmpd daemon for new changes to take effect:
# /etc/init.d/snmpd restart
Stopping snmpd: [ OK ]
Starting snmpd: [ OK ]
What's pros and cons of this network monitor? I'm using total network monitor and never tried solarwinds solution. I need something for Server management on Linux.
ReplyDeleteThese days, specially for cloud monitoring, you should consider Datadog, a SaaS monitoring solution.
