I wanted to build a menu item in Zabbix to open a ticket against a host in Zabbix so that we could flag one for attention.

I finally got around to playing with the Telstra SMS API some more after very successfully using it to send messages from my Zabbix instance at home.

I wanted to get responses from the messages so that I could potentially automate some responses if I get an alert via my Zabbix instance.

In my last post, I built a script to poll my modem via Telnet to retrieve ADSL stats.

In this post, I’ll be using the output of the last script to put the values into Zabbix so I have some history to refer to.

I’ve finally gotten around to working on my projects again after doing some exams.

I wanted to get some ADSL monitoring going so I could get some history on the state of my line, get sync rates etc.

The first thing I needed to do was get the modem stats via a script as Zabbix couldn’t login to the modem properly.
I did a quick python script that can be called from Zabbix to get the modem stats.

I had to build my own email sender script for Zabbix as I needed some mangling done on the subjects that was being sent out.
I used python to build it so that I could then use some regex to strip out the garbage that I needed stripped out.

First thing you need to do is to create the email script for Zabbix to run when it receives an alert.
The default location for these scripts is /usr/lib/zabbix/alertscripts/ but this can be customised from the Zabbix server configuration file.

This is the python script that I used, I named it emailalert.py, so the full path for this script should be /usr/lib/zabbix/alertscripts/emailalert.py.

In this example script, I’m only removing text <EMAIL> from any subjects that may have it. This is because some alerts that are being generated have an <EMAIL> tag to enable Zabbix to recognise that the alert needs to go through email, however the team receiving the alert doesn’t want the <EMAIL> tag on the subject line of the email they receive.

#!/usr/bin/python
import smtplib
import sys
import re

email = sys.argv[1]
subject = sys.argv[2]
body = sys.argv[3]

subject = re.sub('<EMAIL>',"",subject)

sender = "Zabbix <zabbix@example.com>"

message = """From: Zabbix <zabbix@example.com>
To: """+email+"""
Subject: """+subject+"""

"""+body+"""
"""

try:
smtpObj = smtplib.SMTP("smtpserver.example.com")
smtpObj.sendmail(sender,email,message)
print "Success"
except SMTPException:
print "Unable to send email"

Once the script has been created, you’ll need to add the script to the Media Types under Administration in Zabbix.
Create a new media type, and give it a name. I’ve called mine Email Script.
For the type, choose Script, and then for the Script Name, use the name that you’ve given the script. In my case, I’ve called it emailalert.py

My Media type configuration

My Media type configuration

Once this is done, you’ll need to set up email addresses for users that need emails through this new script by going to each user, and setting up a new media entry with the type being Email Script
