Hello, im doing port monitoring of various switches in nagios and it works wonderful.
But I issue I face is, Im not able to know which port is doing what unless I remember.
For example, I get notification s
DEVICE CISCO A = port 21 down.
But I want to label my ports like , port 21 (current sensor)
So, notification should come like
DEVICE CISCO A = port 21 down (current sensor ) is down.
Can we label a port in nagios hosts ?
Re: Can we label a port in nagios hosts ?
If you want to add custom labels / information to your service checks to get betters details / descriptions, you could use the Notes object.
The description of the notes object.
Just add the notes object to your service checks and then you would have to edit your notification command and add the $SERVICENOTES$ macro to it so when an email is sent, it will also send the information from the notes field from your service.

Re: Can we label a port in nagios hosts ?
So lets say, my host group is - DC001 NOC SWITCHES.
And one host added is - CORE NOC CISCO 001 SWITCH
And Im monitoring the ports ge0/0/1 and ge0/0/11
Can I name ge0/0/11 as "NOC SWITCH CURRENT SENSOR" ?
So, when the port goes off,
will I get email like,
DC001 NOC SWITCHES
NOC SWITCH CURRENT SENSOR is critical ?
And one host added is - CORE NOC CISCO 001 SWITCH
And Im monitoring the ports ge0/0/1 and ge0/0/11
Can I name ge0/0/11 as "NOC SWITCH CURRENT SENSOR" ?
So, when the port goes off,
will I get email like,
DC001 NOC SWITCHES
NOC SWITCH CURRENT SENSOR is critical ?
Re: Can we label a port in nagios hosts ?
If you add the "NOC SWITCH CURRENT SENSOR" to the notes object for that service and edit the notify-service-by-email command to add the notes field and the Hostgroup macro to it, you could format the email to how you would like it to look.
Try editing the notify-service-by-email command like the example below, and see if this is what you are looking for.
What I did was add the following to the command in the body of the message
That will add the hostgroup name as well as the Notes field to the email notification.
Try editing the notify-service-by-email command like the example below, and see if this is what you are looking for.
Code: Select all
/usr/bin/printf "%b" "***** Nagios Monitor XI Alert *****\n\nNotification Type: $NOTIFICATIONTYPE$\n\nService: $SERVICEDESC$\nHost: $HOSTALIAS$\nAddress: $HOSTADDRESS$\nState: $SERVICESTATE$\n\nDate/Time: $LONGDATETIME$\n\nAdditional Info:\n\n$SERVICEOUTPUT$\n$HOSTGROUPNAME$\n$SERVICENOTES$" | /bin/mail -s "** $NOTIFICATIONTYPE$ Service Alert: $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$ **" $CONTACTEMAIL$
Code: Select all
\n$HOSTGROUPNAME$\n$SERVICENOTES$

Re: Can we label a port in nagios hosts ?
You would put the notes field in the service check for the port check.
Code: Select all
define service{
use generic-service ; Inherit values from a template
host_name LEWIS
service_description Port 4 Link Status
check_command check_snmp!-C test -o ifOperStatus.10604 -r 1 -m RFC1213-MIB
notes "Put your label/note here"
}
