Nagios Support Forum

Hello Everybody

i need to monitor a APC switched i already config the ip and snmp community on the powerstrip AP7830 and AP7932 so i config snmp to monitor and i already it monitoring but the issue is i need to divide by 100 the output result since it is coming from snmp is there a way to divide the result by 100 or is this a plugin that works because i could not find one that seem to work

this is my service

define service{
use generic-service,srv-pnp
service_description Total Load
check_command check_snmp!1.3.6.1.4.1.318.1.1.12.2.3.1.1.2.1
max_check_attempts 3
check_interval 5
retry_interval 1
check_period workhours
hostgroup APC
notification_interval 60
notification_period workhours
contacts nagiosadmin


my command


# 'check_snmp' command definition
define command{
command_name check_snmp
command_line $USER1$/check_snmp -H $HOSTADDRESS$ -C XXXXXX -o $ARG1$


i get out result like this

./check_snmp -H x.x.x.x -C XXXXX -o .1.3.6.1.4.1.318.1.1.12.2.3.1.1.2.1
SNMP OK - 94 | iso.3.6.1.4.1.318.1.1.12.2.3.1.1.2.1=94

now the result need to be divided by 100 i.e 9.4 which is the most idea scenario

any feedback or help will be appreciated

You know I keep thinking that the check_snmp plugin needs a divide or multiple argument.

Anyway, today I learned how to use awk which can do what you want (my head hurts now )

I'm not sure if this will affect the exit codes from Nagios if you introduced warning and critical thresholds.

This: Should produce: 94 divide 10 = 9.4

Just change the /10 values if you want the decimal place shifted.

i got the our put of this

External command error with no output (return code: 3)- 0|=0

nevermind it works you are the best i dont care what anybody said... it was my falut snmp config correct

let me rephrase it work just like that but i need to see of nagios con take the command and display it as it should

You'll want to create a wrapper script, and have it run the check_snmp script. That way, it'll appear as you're looking for in the interface. For example -

check_snmp_apc_custom.sh - Then, assign a command to Nagios so that it uses the above, and then assign that command to the specific service. You may need to write out a few different bash scripts (or integrate dynamic variables) for the different APC's.

Is that what you were looking for?

basically what i was looming for a more of a number that display like 9.4 amps instead of 94 which either way i can make adjustment but i prefer to use 9.4... but it seem you are telling me that you want me to create a wrapper script called "check_snmp_apc_custom.sh" which runs command "./check_snmp -H x.x.x.x -C XXXXX -o .1.3.6.1.4.1.318.1.1.12.2.3.1.1.2.1 | awk -F'|' '{split($1,array_left,"-");} {split($2,array_right,"=");} {print array_left[1]"- "array_left[2]/10"|"array_right[1]"="array_right[2]/10;}'"


then assign a command to it thru command.cfg and a service.cfg can i get a quick examples pf these i think i understand but would like some clarification on them. Once i understadn the process i can create i couple more

thank you for all your help everybody

Command:
In your service you would have: Basically the wrapper script means that you would need a separate script per device, as your script has hard coded in the address for the device.

You could submit $HOSTADDRESS$ as well, however then you would need to code the script to get the address provided to it.
Something like that.

thank that worked perfectly you guys are the best

If you don't have any more questions, shall we close and lock this post?
