Jakarta interSeptor is a server room grade temperature and humidity monitoring device that offers SNMP access:
https://www.jacarta.com/interseptor/
To manually check your temp and humidity run:
temperature:
/usr/local/nagios/libexec/check_snmp -H _interSeptor_IP_ -C _Community_String_ -o .1.3.6.1.4.1.19011.1.3.1.1.3.2.1.3.1
humidity
/usr/local/nagios/libexec//check_snmp -H _interSeptor_IP_ -C _Community_String_ -o .1.3.6.1.4.1.19011.1.3.1.1.3.2.1.5.1
the output will look like this:
SNMP OK – 207 | iso.3.6.1.4.1.19011.1.3.1.1.3.2.1.3.1=207
Please note that all temperature and humidity values are multiplied by ten when retrieved.
Therefore the returned values should be divided by ten once retrieved to attain the actual
reading.
To deal with that problem in the: /usr/local/nagios/libexec/ folder create check_interSeptor.sh file then paste this:
#!/bin/bash # $1 - hostname # $2 - SNMP community string # $3 - oid # $4 - Header # temp oid =.1.3.6.1.4.1.19011.1.3.1.1.3.2.1.3.1 # humidity oid = .1.3.6.1.4.1.19011.1.3.1.1.3.2.1.5.1 # oid details: https://www.jacarta.com/wp-content/uploads/interSeptor-Alarm-OIDs.pdf snmp=$(/usr/local/nagios/libexec/check_snmp -H $1 -C $2 -o $3|cut -b 11-14) var=$(echo "scale=2; $snmp/10" | bc ) output=$(echo "$4 - $var | $4=$var" ) echo $output
save the file and make it executable then test it:
/usr/local/nagios/libexec/check_interSeptopr.sh _interSeptor_IP_ _Community_String_ .1.3.6.1.4.1.19011.1.3.1.1.3.2.1.5.1 Humidity
Humidity – 42.20 | Humidity=42.20
Now back to Nagios:
in the commands.cfg define command:
define command {
command_name check_interSeptor
command_line $USER1$/check_interSeptopr.sh $HOSTADDRESS$ $ARG1$ $ARG2$ $ARG3$
}
then define services:
define service{
use generic-service
host_name interseptor
service_description Temperature
check_command check_interSeptor!BVFB2unUAX!.1.3.6.1.4.1.19011.1.3.1.1.3.2.1.3.1!Temperature
}
define service{
use generic-service
host_name interseptor
service_description Humidity
check_command check_interSeptor!BVFB2unUAX!.1.3.6.1.4.1.19011.1.3.1.1.3.2.1.5.1!Humidity
}
