python-protobix
is a very simple python module which implements Zabbix Sender protocol 2.0.
It allows to build a list of Zabbix items and send them as trappers
.
Currently python-protobix
supports "classics" items
as well as Low Level Discovery
ones.
Please note that python-protobix
is developped and tested on Debian GNU/Linux only.
I can't enforce compatibility with other distributions, though it should work on any distribution providing Python 2.7 or Python 3.x.
Any feedback on this is, of course, welcomed.
To install all required dependencies and launch test suite
python setup.py test
By default, all tests named like *need_backend*
are disabled, since they need a working Zabbix Server.
If you want to run theses tests as well, you will need:
- a working Zabbix Server 3.x configuration file like the one in
tests/zabbix/zabbix_server.conf
- SQL statements in
tests/zabbix/zabbix_server_mysql.sql
with all informations to create testing hosts & items
You can then start Zabbix Server with zabbix_server -c tests/zabbix/zabbix_server.conf -f
and launch test suite with
py.test --cov protobix --cov-report term-missing
You can also use docker to run test suite on any Linux distribution of your choice.
You can use provided script docker-tests.sh
as entrypoint example:
docker run --volume=$(pwd):/home/python-protobix --entrypoint=/home/python-protobix/tests/docker-tests.sh -ti debian:jessie
Currently, entrypoint docker-tests.sh
only supports Debian GNU/Linux.
Please note that this docker entrypoint does not provide a way to execute test that need a backend.
With pip
(stable version):
pip install protobix
With pip
(test version):
pip install -i https://testpypi.python.org/simple/ protobix
Python is available as Debian package for Debian GNU/Linux sid and testing.
Once module is installed, you can use it either extending protobix.SampleProbe
or directly using protobix.Datacontainer
.
python-protobix
provides a convenient sample probe you can extend to fit your own needs.
Using protobix.SampleProbe
allows you to concentrate on getting metrics or Low Level Discovery items without taking care of anything related to protobix
itself.
This is the recommanded way of using python-protobix
.
protobix.SampleProbe
provides a run
method which take care of everything related to protobix
.
Some probes are available from my Github repository python-zabbix

Sample Python class which extends protobix.SampleProbe
'''
import protobix
import argparse
import socket
import sys
class ExampleProbe(protobix.SampleProbe):
__version__ = '1.0.2'
# discovery_key is *not* the one declared in Zabbix Agent configuration
# it's the one declared in Zabbix template's "Discovery rules"
discovery_key = "example.probe.llddiscovery"
def _parse_probe_args(self, parser):
# Parse the script arguments
# parser is an instance of argparse.parser created by SampleProbe._parse_args method
# you *must* return parser to SampleProbe so that your own options are taken into account
example_probe_options = parser.add_argument_group('ExampleProbe configuration')
example_probe_options.add_argument(
"-o", "--option", default="default_value",
help="WTF do this option"
)
return parser
def _init_probe(self):
# Whatever you need to initiliaze your probe
# Can be establishing a connection
# Or reading a configuration file
# If you have nothing special to do
# Just do not override this method
# Or use:
pass
def _get_discovery(self):
# Whatever you need to do to discover LLD items
# this method is mandatory
# If not declared, calling the probe ith --discovery option will resut in a NotimplementedError
# If you get discovery infos for only one node you should return data as follow
return { self.hostname: data }
# If you get discovery infos for many hosts, then you should build data dict by yourself
# and return result as follow
return data
def _get_metrics(self):
# Whatever you need to do to collect metrics
# this method is mandatory
# If not declared, calling the probe with --update-items option will resut in a NotimplementedError
# If you get metrics for only one node you should return data as follow
return { self.hostname: data }
# If you get metrics for many hosts, then you should build data dict by your self
# and return result as follow
return data
if __name__ == '__main__':
ret = RedisServer().run()
print ret
sys.exit(ret)
Declare your newly created probe as Zabbix Agent
user parameters:
UserParameter=example.probe.check,/usr/local/bin/example_probe.py --update-items
UserParameter=example.probe.discovery,/usr/local/bin/example_probe.py --discovery
You're done.
The protobix.SampleProbe
exit code will be sent to Zabbix.
You'll be able to setup triggers if needed.
Exit codes mapping:
- 0: everything went well
- 1: probe failed at step 1 (probe initialization)
- 2: probe failed at step 2 (probe data collection)
- 3: probe failed at step 3 (add data to DataContainer)
- 4: probe failed at step 4 (send data to Zabbix)
If you don't want or can't use protobix.SampleProbe
, you can also directly use protobix.Datacontainer
.
How to send items updates
