Hello all
We have since a few weeks Checkmk (Raw Edition 2.1.0p19 on Ubuntu 22.04 LTS) and want to replace our existing Nagios3.
In Nagios3 we have SMS sending via Gammu and a USB modem (Huawei Surfstick E303).
Sending SMS works via console (echo “Hello recipient :)” | gammu sendsms TEXT 004179xxxyyzz).
Haven’t found any instructions/scripts on how exactly I teach checkmk to send SMS.
In Nagios we use this command:
# 'notify-host-by-gsm' command definition
define command{
command_name notify-host-by-gsm
command_line /usr/bin/printf "%b" "$NOTIFICATIONTYPE$: Host - $HOSTNAME$ is $HOSTSTATE$ / Info: $HOSTOUTPUT$ / Date/Time: $LONGDATETIME$" | gammu sendsms TEXT $_CONTACTGSM$
}
# 'notify-service-by-gsm' command definition
define command{
command_name notify-service-by-gsm
command_line /usr/bin/printf "%b" "$NOTIFICATIONTYPE$: $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$ / Info: $SERVICEOUTPUT$ / Date/Time: $LONGDATETIME$" | gammu sendsms TEXT $_CONTACTGSM$
}
Will this easy work with Gammu or do you use another tool for sending SMS with a SIM Card in an USB Modem?
I created a new user attribute, because i used already Contactpager. The new attribute is called mobilephone. How can I use this?
Thanks for your help

You would need to create your own notification plugin.
An example is the sms plugin which uses smssend to generate the SMS.

from cmk.notification_plugins.utils import collect_context, get_sms_message_from_context
show original
Put your own notification plugin in $OMD_ROOT/local/share/check_mk/notifications. After that you can select it in the dropdown of the notification rule.
If it is working build an extension package and publish it to the Exchange: https://exchange.chekcmk.com/

The attribute gets “translated” into a new env variable for the notification plugin script.
Use “env | sort > /tmp/notification.env” in your script to see them all.
