# What is Zabbix?

Zabbix is an enterprise-class open source distributed monitoring solution.

Zabbix is software that monitors numerous parameters of a network and the health and integrity of servers. Zabbix uses a flexible notification mechanism that allows users to configure e-mail based alerts for virtually any event. This allows a fast reaction to server problems. Zabbix offers excellent reporting and data visualisation features based on the stored data. This makes Zabbix ideal for capacity planning.

# What is the image?

The image is used to receive SNMP traps, store them to a log file and provide access to Zabbix to collected SNMP trap messsages.

# Zabbix snmptraps images

These are the only official Zabbix snmptraps Podman images. Images are updated when new releases are published.

# How to use this image

## Start `zabbix-snmptraps`

Start a Zabbix snmptraps container as follows:

    podman run --name some-zabbix-snmptraps -p 162:1162/udp -d zabbix/zabbix-snmptraps:tag

Where `some-zabbix-snmptraps` is the name you want to assign to your container and `tag` is the tag specifying the version you want. See the list above for relevant tags, or look at the full list of tags.

## Linking Zabbix server or Zabbix proxy with the container

    podman run --name some-zabbix-server --link some-zabbix-snmptraps:zabbix-snmptraps --volumes-from some-zabbix-snmptraps -d zabbix/zabbix-server:tag

## Container shell access and viewing Zabbix snmptraps logs

The `podman exec` command allows you to run commands inside a Podman container. The following command line will give you a bash shell inside your `zabbix-snmptraps` container:

    $ podman exec -ti some-zabbix-snmptraps /bin/bash

The Zabbix snmptraps log is available through Podman's container log:

    $ podman logs  some-zabbix-snmptraps

## Environment Variables

### `ZBX_SNMP_TRAP_USE_DNS`

This variable manages source network address representation. It can be IP address or DNS of SNMP trap sender. The variable works only when container command is modified and "-n" command argument is removed from argument list. By default, value is `false`.

## Allowed volumes for the Zabbix snmptraps container

### `/var/lib/zabbix/snmptraps`

The volume contains log file `snmptraps.log` named with received SNMP traps.

### `/var/lib/zabbix/mibs`

The volume allows to add new MIB files. It does not support subdirectories, all MIBs must be placed to `/var/lib/zabbix/mibs`.
