[question] on Ports, ZeroMQ, Zabbix Agent

[rockaut]

Hello there,

before i proceed with further Docker Container implementations and usage with Zabbix i have some basic questions. I already had some looks in the docs and also the code as such but haven't come to an definitive conclusion.

1. Ports
   There are 4 ports i see which need to be configured.

• proxy frontend, backend and management
• worker management

Is it correct to state that ...

• a worker talks to proxy backend
• a worker mgmt is only used by the worker itself
• a proxy mgmt is only used by the proxy itself
• a zabbix agent would talk to proxy frontend

Maybe the ports can be mentioned on http://vpoller.readthedocs.io/en/latest/terminology.html too.

2. Zabbix Agent fetching vPoller Data
   How exactly is the zabbix agent getting the data from vPoller?
   In the zabbix vpoller-module (https://github.com/dnaeon/py-vpoller/blob/master/extra/zabbix/vpoller-module/vpoller.c) i found a mention for zmq in zbx_module_vpoller function. Does that mean that the zabbix agent needs a zmq connection to proxy zmq? Is it even possible to install an fetch the data with the Zabbix Module and Zabbix Agent from another Machine/VM/Container and not running on the vpoller host itself?

Thats it ... for now ;-)

best regards
Markus

Hey Markus,

You are correct about the ports. Would be nice to have these documented as well. Do you mind submitting a PR to update the documentation?

On the second point - yes, the vpoller module for Zabbix is built with zeromq support, so generally the module sends a zeromq message to the vpoller proxy (front end) and waits for a response.

There is also a configuration file for the vpoller module itself, which allows you to configure where exactly the proxy is located, so you don’t have to run a proxy locally.

Let me know if you have other questions.

Thanks,
Marin
