WARNING !!!

All development in this repositoryy is frozen. Future development will continue here https://github.com/vulogov/zlm-cython

pyzabbix-agent

The pyzabbix-agent loadable module is a way to extend zabbix_agentd daemon with Python. The main goal is to avoid costly and slow exec calls and loading of the interpreter.

Installation.

At this moment, I do not recommend to use this module in a production environment. There are bugs. There are undetected issues.

  • Check the include path and compilation parameters in Makefile and run make.

  • Copy python.so to the directory defined by LoadModulePath in zabbix_agentd.conf

  • Create subdirectory pymodules in the directory where your configuration file is installed

  • Install the Python Zabbix modules in this directory.

  • Add LoadModule=python.so in your zabbix_agentd.conf.

  • Set the PYTHONPATH as:

export PYTHONPATH=`python -c "import sys; print ':'.join(sys.path)"`

This is not mandatory anymore, if PYTHONPATH is not defined, module will discover it from Python interpreter.

  • Restart zabbix_agentd

Zabbix Python module

This is a regular python module, where you shall define function main(*args). All arguments passed from Zabbix to an agent, will be passed to a main() functions as srings. The return value will be returned to Zabbix. Only Int, Long, Float and String information types are supported as return values.

"Special" Zabbix modules

These modules perform some special actions.

  • ZBX_startup.py - module, which main() function will be executed during zabbix_agentd startup

  • ZBX_finish.py - module, which main() function will be executed during zabbix_agentd finish

Python interface

The following item keys are supported:

  • python.ping - no parameters. Return 1 if embedded Python is initialized
  • python.version - returns version of the embedded Python interpreter
  • python - calling the Python Zabbix module. The first parameter is the name of the module, the next parameters will be passed to the main() function of the module.
  • python.prof - same as python, but instead returning the value, returns execution time of the module in miliseconds.
  • py[] - same as python[], but wrapping module interface through ZBX_call.py. In addition to a calling main() function of the module, can call any function and also read data from pre-spawned agents and a Redis queues.
