Hi Subhendu,

Appologies for the silly question but what do you mean add a -m?



Add a "-m:"
The colon after the -m option indicates an empty miblist. You don't need a miblist if you are providing a numeric OID. A normal miblist is a colon separated list of directories containing mib files. It is used by the snmpget utility to translate to a numeric OID. e.g. system.sysDescr.0 ==> .1.3.6.1.2.1.1.1.0 

Also please post the result of the following:
snmpget -v 1 -c public 10.30.129.30 .1.3.6.1.4.1.2012.1.1.1.4.2.0

If you see data other than
SNMPv2-SMI::enterprises.2012.1.1.1.4.2.0 = INTEGER: 69
then you may have some local mib files that don't have the correct syntax.
The WARNING is then the result of output seen on STDERR where it was not expected. 


when i run:
./check_snmp -H 10.30.129.30 -o .1.3.6.1.4.1.2012.1.1.1.4.2.0 -w 80 -c 85 -C public -v -m 
i get ./check_snmp: option requires an argument -- m

how do i find out what the miblist is????

WHEN I RUN:
./check_snmp -H 10.30.129.30 -o .1.3.6.1.4.1.2012.1.1.1.4.2.0 -w 80 -c 85 -C public -v 

i get:
/usr/bin/snmpget -t 1 -r 5 -m ALL -v 1 -c public 10.30.129.30:161 .1.3.6.1.4.1.2012.1.1.1.4.2.0 
SNMPv2-SMI::enterprises.2012.1.1.1.4.2.0 = INTEGER: 69

SNMP WARNING - 69
NOTE if it is of any use, there is a line space between SNMP WARNING - 69 and INTEGER 69

Hi

Thanks for the info, but im affraid it still isn't working :-(

FYI
Usage: check_snmp -H <ip_address> -o <OID> [-w warn_range] [-c crit_range] 
                [-C community] [-s string] [-r regex] [-R regexi]

[-L seclevel] [-U secname] [-a authproto] [-A authpasswd] 
                [-X privpasswd]
i try running the command: ./check_snmp -H 10.30.129.30 -o .1.3.6.1.4.1.2012.1.1.1.4.2.0 -w 80 -c 85 -C public 

and still get a value of "SNMP WARNING - 69" back
accoring to the command im running should the waring only come up when the -w parameter is met? - i.e 80 and critical when its 85?? 

Any help would be great



Add a "-m:"

Also please post the result of tagging on a "-v" option

-sg

Well, you haven't told check_snmp if that's OK or CRITICAL so it doesn't know what to report it as, hence WARNING. Remember the OIDs can contain just about any kind of data and check_snmp has no idea what it is you're querying, it just has an SNMP 'address'. You have to add in the status 
intelligence.

I'm not sure what version of check_snmp you're using but -wv and -cv 
aren't valid command line args, at least with 1.4 and prior.

You just need to tell check_snmp what to expect for each range.
Check_snmp (and a couple other plugins) behave differently than other plugins WRT warning and critical detection as the results of the SNMP 
query are highly variable. Here are a couple of examples --
To test for a very specific value where anything but that value is bad 
you might use something like -
define command{
        command_name    check_bgp_peer_state
        command_line    $USER1$/check_snmp -H $HOSTADDRESS$ -o
.1.3.6.1.2.1.15.3.1.2.$ARG1$ -s 6 -C $USER3$ -l 'BGP Peer $ARG1$ State' 
        }
The above will be OK if the value of that OID is 6 and CRITICAL if it's 
anything else.

To check for a range of values you might use the following -

define command{
        command_name    check_temperature_server_sites
command_line $USER1$/check_snmp -H $HOSTADDRESS$ -u 'Degrees Celsius' -o .1.3.6.1.4.1.9.9.13.1.3.1.3.2 -C $USER3$ -w 37:32 -c 99:38 
-l '
Temperature is'
        }
The above will result in WARNING if the value of the OID is between 32 and 37 (inclusive), CRITICAL if it's between 38 and 99 (inclusive) and 
OK for all other values.
Hope that helps. Use 'check_snmp --help' for other command line args and 
their description.
