Hi again Nagios Community,

Been attempting to get snmp working again to find the temperature of a server, etc.

After trying with check_snmp but getting nowhere, I decided to try out check_snmp_temperature.pl.

So, I've added it as a command and as a service as follows;

Code: Select all

define service{
       use                     local-service
       host_name               tiger
       service_description     SuperMicro Temp
       check_command           check_snmp_temperature.pl!public!.1.3.6.1.4.1.10876.2.1.1.1.1.2.20
       }

# 'check_snmp_temperature.pl' command definition
define command{
        command_name    check_snmp_temperature.pl
        command_line    $USER1$/check_snmp_temperature.pl -H $HOSTADDRESS$ -v2c -C public -N $ARG1$
        }

The following is the error;

Code: Select all

Specify system type (-T) OR base SNMP OIDs for names (-N) and data (-D) tables OR exact list of sensor names (-n) and data OIDs (-d) !

Usage: /usr/local/icinga/libexec/check_snmp_temperature.pl [-v] -H <host> -C <snmp_community> [-2]

Performance Data:	(-l login -x passwd [-X pass -L <authp>,<privp>]) [-p <port>] [-t <timeout>] -T dell|hp|cisco1|juniper|alteon | [-N <oid_attribnames> -D <oid_attribdata>] | [-n <list of sensor names> -d <list of sensor oids>] [-a <attributes to check> -w <warn levels> -c <crit levels> [-f]] [-A <attributes for perfdata>] [-o <out_temp_unit: C|F|K>] [-i <in_temp_unit>] [-u <unknown_default>] [-V]

Any tips please? I'm sure what to add for the -D option really, -N is all I could find online...

Thank you.

Kind Regards,

gshergill

EDIT:

root@nagios:/usr/local/nagios/etc/objects# snmpwalk -v2c -c public server.domain .1.3.6.1.4.1.10876.2.1.1.1.1.2.20

Is this on a Nagios XI machine? Also can you link to which plugin you downloaded...

Thanks

Hi scottwilkerson,

My apologies, I posted the wrong VM's error. I currently use 4 VM's for this, 3 of which I use to test command/service definitions for the production machine (don't want to break what is already, to an extent, working).

This is the webpage error;

Code: Select all

Specify system type (-T) OR base SNMP OIDs for names (-N) and data (-D) tables OR exact list of sensor names (-n) and data OIDs (-d) !

The service definition in grumbler.domain.cfg;

Code: Select all

define service{
        use                     local-service
        host_name               grumbler.domain
        service_description     SuperMicro Temp
        check_command           check_snmp_temperature.pl!.1.3.6.1.4.1.10876.2.1.1.1.1.2.20
        max_check_attempts              5
        check_interval                  5
        retry_interval                  1
        check_period                    xi_timeperiod_24x7
        notification_interval           60
        notification_period             xi_timeperiod_24x7
      }

And the command definition in commands.cfg;

Code: Select all

define command {
       command_name                             check_snmp_temperature.pl
       command_line                             $USER1$/check_snmp_temperature.pl -H $HOSTADDRESS$ -v2c -C public -N $ARG1$
}

The check_snmp_temperature.pl being used is at the following link;

http://exchange.nagios.org/directory/Pl ... re/details

I chose Version 0.35 rather than the BETA version.

Thank you.

Kind Regards,

I'm not totally familiar with this 3rd party plugin but it looks like you need to also give it the -D with the -N as well as a -a

./check_snmp_temperature.pl -h

SNMP Temperature Monitor for Nagios version 0.34
by William Leibzon - william(at)leibzon.org

Usage: ./check_snmp_temperature.pl [-v] -H <host> -C <snmp_community> [-2] | (-l login -x passwd [-X pass -L <authp>,<privp>]) [-p <port>] [-t <timeout>] -T dell|hp|cisco1|juniper|alteon | [-N <oid_attribnames> -D <oid_attribdata>] | [-n <list of sensor names> -d <list of sensor oids>] [-a <attributes to check> -w <warn levels> -c <crit levels> [-f]] [-A <attributes for perfdata>] [-o <out_temp_unit: C|F|K>] [-i <in_temp_unit>] [-u <unknown_default>] [-V]
-v, --verbose
print extra debugging information
-h, --help
print this help message
-H, --hostname=HOST
name or IP address of host to check
-C, --community=COMMUNITY NAME
community name for the host's SNMP agent (implies v 1 protocol)
-2, --v2c
Use snmp v2c
-l, --login=LOGIN ; -x, --passwd=PASSWD
Login and auth password for snmpv3 authentication
If no priv password exists, implies AuthNoPriv
-X, --privpass=PASSWD
Priv password for snmpv3 (AuthPriv protocol)
-L, --protocols=<authproto>,<privproto>
<authproto> : Authentication protocol (md5|sha : default md5)
<privproto> : Priv protocole (des|aes : default des)
-P, --port=PORT
SNMP port (Default 161)
-w, --warn=INT[,INT[,INT[..]]]
warning temperature level(s) (if more then one attribute is checked, must have multiple values)
-c, --crit=INT[,INT[,INT[..]]]
critical temperature level(s) (if more then one attribute is checked, must have multiple values)
-f, --perfdata
Perfparse compatible output
-t, --timeout=INTEGER
timeout for SNMP in seconds (Default: 5)
-V, --version
prints version number
-N, --oidtable_attribnames=OID_STRING
Base table OID to walk through to find names of those attributes supported and from that corresponding data OIDs
-D, --oidtable_attribdata=OID_STRING
Base table OID for sensor attribute data, one number is added to that to make up full attribute OID
-n, --sensor_names=STRING[,STRING[..]]
List of sensor names when -N is not used and sensors are specified with exeact oids
-d, --sensor_oids=OID_STRING[,OID_STRING[..]]
List of exact data OIDs for sensors specified with -n (specify this when -N and -D are not used)
-a, --attributes=STRING[,STRING[..]]
Which attribute(s) to check. This is used as regex to check if attribute is found in sensor names.
As an example for Dell the attribute names to use are: PROC_1, PROC_2, Ambient, Planar, Riser
-A, --perf_attributes=STRING[,STRING[..]]
Which attribute(s) to add to as part of performance data output. These names can be different then the
ones listed in '-a' to only output attributes in perf data but not check. Special value of '*' gets them all.
-f, --perfparse
Used only with '-a'. Causes to output data not only in main status line but also as perfparse output
-o --out_temp_unit=C|F|K
What temperature measurement units are used for output and warning/critical - 'C', 'F' or 'K' - default is 'C'
-i --in_temp_unit=[num]C|F|K
What temperature measurement reported by data OID - format is <num>C|F|K (default is 'C')
where num is used if data is num*realdata, i.e. if reported data of 330 means 33C, then it is: -i 10C
-u, --unknown_default=INT
If attribute is not found then report the output as this number (i.e. -u 0)
-T, --type=dell|hp|cisco1|juniper|alteon
This allows to use pre-defined system type to set Base, Data OIDs and incoming temperature measurement type
Currently support systems types are: dell, hp, cisco1 (7500, 5500, 2948, etc), juniper, alteon

Hi scottwilkerson,

The problem I'm having is that after a long time I found a -N that works on snmpwalk, but I honestly haven't a clue what the -D needs to be for this command, let alone the -a.

Any chance you know what I should/could put there please?

It's a SuperMicro motherboard.

Thank you.

Kind Regards,

gshergill

Honestly, I'm not familiar with this 3rd party plugin, you may want to post the question to the exchange page or email the author
