snmp manage load

snmp will monitor the load over a 1, 5, and 15 minute average.

e.g.:

load 5 6 7

This tells the load should be under 5 for 1 min ave
This tells the load should be under 6 for 5 min ave
This tells the load should be under 7 for 15 min ave

snmp manage proc

Add proc monitoring to snmpd.conf:

proc my_proc_name [max_instances] [min_instances]

This will monitor dbid:
proc dbid

This will make sure dbid has no more than 3 instances
proc dbid 3

This will makesure dbid has not more than 3 and no less than 1 instance
proc dbid 3 1

snmp manage disk

Add disk monitoring to snmpd.conf:

disk /
disk /boot
disk /usr

snmp remote gui browser

Normally I am all about command line, but if you need to use windows I really recommend using SNMP-Probe. It has a 10 day trial and is only 15 USD for a license. It is really nice for us snmp noobs.

snmp config setup for snmpd

Snmp is really cool, but seems to difficult to setup. I kept getting a "Timeout: No Response from localhost" when I would try to run snmpget to query the mib. I checked the snmpd log and it said that conf was probably bad and that snmpd would probably not be very useful.

I then stumbled on:
snmpconf -g basic_setup

If you're a noob to , like me, this will probably save your bacon. I just followed in guide. Oh btw, you probably want to make a community name of public. This will be helpful when following tutorials that will often use the -c option and assign the value public. e.g. snmpget -v 1 -c public localhost SNMPv2-MIB::sysUpTime.0

Btw, remember to move the snmpd.conf file to /path/to/snmp/share/snmp/
