snmp for monitor routers

[Tedman Eng]

Consider the check_ifstatus.pl, check_bgpstate.plm and checkciscotemp.pl
plugins, which are basically check_snmp in a perl chocolate candy shell.


If you prefer to roll your own, 
here's some OIDs to try:

OID     cpu1min     .1.3.6.1.4.1.9.2.1.57.0
OID     cpu5min     .1.3.6.1.4.1.9.2.1.58.0
OID     tempInlet   .1.3.6.1.4.1.9.9.13.1.3.1.3.1
OID     tempOutlet  .1.3.6.1.4.1.9.9.13.1.3.1.3.3
OID     tempState   .1.3.6.1.4.1.9.9.13.1.3.1.6.1
OID     mem5minUsed .1.3.6.1.4.1.9.9.48.1.1.1.5.1
OID     mem5minFree .1.3.6.1.4.1.9.9.48.1.1.1.6.1
OID     IfAdminStatus = '1.3.6.1.2.1.2.2.1.7
OID     IfDescr = '1.3.6.1.2.1.2.2.1.2
OID     IfOperStatus = '1.3.6.1.2.1.2.2.1.8
OID     IfName = '1.3.6.1.2.1.31.1.1.1.1
OID     IfAlias = '1.3.6.1.2.1.31.1.1.1.18
OID     LocIfDescr = '1.3.6.1.4.1.9.2.2.1.1.28
OID     IfType = '1.3.6.1.2.1.2.2.1.3

Example:

Here I monitor the temperature inside the router.  If the temperature gets
too high, then there are problems (and possibly a non funtioning air
conditioner!).

command_name    check_snmp_rtr_temp
command_line   $USER1$/check_snmp -l "Outlet Temp" -H $HOSTADDRESS$ -p 161
-C community -o .1.3.6.1.4.1.9.9.13.1.3.1.3.3 -w 40 -c 50

You can pass arguments by using something like this:
check_command  check_snmp_interface_status!1
command_line   $USER1$/check_snmp -o .1.3.6.1.2.1.2.2.1.8.$ARG1$

There's many more depending on model of router.  Check your router's
management guide for available SNMP OID's or MIBs.  Here I use OID numbers,
but you can use the MIB name so long as you have the MIBs loaded to do the
translation.

Refer to "check_snmp --help" for usage info.

For more detailed router trending, consider MRTG or RRDtool.  Nagios is good
at monitoring binary states (ie UP or DOWN),  RRDtool is good for measuring
trends (ie average bandwidth used,   interface error count, etc).  There are
various projects that integrate the two as well.

Dose anyone have example of check with snmp for cisco routers.  I am trying
to monitor my router with nagios.  I want to do more then just monitor with
a check_ping.
