Wireless Access

Hi,

Any idea what is the OID for getting info how many IAP there is in a cluster?

Thanks,

Joakim

Try this one:

aiAccessPointEntry   1.3.6.1.4.1.14823.2.3.3.1.2.1.1 

Situation is that I'm using Nagios but I dont know really understand OID's or SNMP so much.

I can get info like:

check_command               check_snmp!-C password -o .1.3.6.1.2.1.1.3.0

I get system uptime

check_command               check_snmp!-C password -o .1.3.6.1.2.1.1.1.0
I get ArubaOS version

But when I try

check_command               check_snmp!-C password -o 1.3.6.1.4.1.14823.2.3.3.1.2.1.1

I get error iso.3.6.1.4.1.14823.2.3.3.1.2.1.1 = No Such Object available on this agent at this OID

Any help?

Thanks. J

Here is the solution, you need to use SNMP WALK to get AP info of your IAP cluster to work, and for that you need a perl script.

To get this to work you need to have a basic knowledge about configuring Nagios.

So what I did is I ripped a script called check_cisco_ap.sh found from http://exchange.nagios.org/directory/Plugins/Hardware/Network-Gear/Cisco/Check-Cisco-AP-Number/details

(Thanks to Marco Gottardello for the script)

And did few changes to the script

usage="Usage: check_cisco_ap -H <hostname> -C <community> -N

to

usage="Usage: check_aruba_ap -H <hostname> -C <community> -N

and

num_of_ap=`/usr/bin/snmpwalk -v 2c -c $community $hostname 1.3.6.1.4.1.14179.2.2.1.1.37 | wc -l`

to

num_of_ap=`/usr/bin/snmpwalk -v 2c -c $community $hostname iso.3.6.1.4.1.14823.2.3.3.1.2.1.1.2 | wc -l`

Save the file and rename it to "check_aruba_ap.pl"

Upload to the server where you have Nagios installed to the folder called libexec (my path is /usr/local/nagios/libexec)

Edit your command.cfg file and add a line

##### CHECK ARUBA AP COUNT #####

# 'check_aruba_ap' command definition
  define command{
  command_name    check_aruba_ap.pl
  command_line    $USER1$/check_aruba_ap -H $HOSTADDRESS$ $ARG1$       
}

add a line to services.cfg

define service {
    hostgroup_name        Instant Virtual Cluster AP amount 2pcs
    service_description        SNMP Virtual Cluster AP amount 2pcs
    check_command               check_aruba_ap! -C password -N 2
    use                    generic-service
    notification_interval    0 ; set > 0 if you want to be renotified
}

And do as many as you need, in this case we are expecting to have 2 AP's on a cluster. Just replace the -N 2 to some other number (-N exoect) -C is the community string.

Then create a file called for example "my_aruba.cfg"

And add the basic Nagios stuff into it:

############ ARUBA ##############

define  host {

use                                            generic-host
host_name                               My Company Controller
alias                                         My Company Controller

check_command                      check-host-alive
address                                         10.0.6.65
hostgroups                                   Instant Virtual Cluster AP amount 2pcs
notifications_enabled           1       ; Host notifications are enabled
event_handler_enabled           1       ; Host event handler is enabled
flap_detection_enabled          1       ; Flap detection is enabled
failure_prediction_enabled      1       ; Failure prediction is enabled
process_perf_data               1       ; Process performance data
retain_status_information       1       ; Retain status information across program restarts
retain_nonstatus_information    1       ; Retain non-status information across program restarts
max_check_attempts              10
notification_interval           1
notification_period             24x7
notification_options            d,u,r,f,s
contact_groups                  admins
}

And also edit hostgroup.cfg and add

define hostgroup {
    hostgroup_name        Instant Virtual Cluster AP amount 2pcs
    alias                            Instant Virtual Cluster AP amount 2pcs
}

Restart Nagios (service nagios restart) And you're done!
