# 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.
|
||||
|
||||
For more information and related downloads for Zabbix components, please visit https://hub.docker.com/u/zabbix/ and https://zabbix.com
|
||||
|
||||
# What is Zabbix Java Gateway?
|
||||
|
||||
Zabbix Java Gateway performs native support for monitoring JMX applications. Java gateway accepts incoming connection from Zabbix server or Zabbix proxy and can only be used as a "passive proxy".
|
||||
|
||||
# Zabbix Java Gateway images
|
||||
|
||||
These are the only official Zabbix Java Gateway Docker images. They are based on Alpine Linux v3.12, Ubuntu 20.04 (focal) and CentOS 8 images. The available versions of Zabbix Java Gateway are:

|
||||

|
||||
Zabbix Java Gateway 6.0 (tags: alpine-trunk, ubuntu-trunk, centos-trunk)
|
||||
|
||||
Images are updated when new releases are published. The image with ``latest`` tag is based on Alpine Linux.
|
||||
|
||||
# How to use this image
|
||||
|
||||
## Start `zabbix-java-gateway`
|
||||
|
||||
Start a Zabbix Java Gateway container as follows:
|
||||
|
||||
docker run --name some-zabbix-java-gateway -d zabbix/zabbix-java-gateway:tag
|
||||
|
||||
Where `some-zabbix-java-gateway` 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](https://hub.docker.com/r/zabbix/zabbix-java-gateway/tags/).
|
||||
|
||||
## Linking the container to Zabbix server or Zabbix proxy
|
||||
|
||||
docker run --name some-zabbix-java-gateway --link some-zabbix-server:zabbix-server -d zabbix/zabbix-java-gateway:tag
|
||||
|
||||
## Container shell access and viewing Zabbix Java Gateway logs
|
||||
|
||||
The `docker exec` command allows you to run commands inside a Docker container. The following command line will give you a bash shell inside your `zabbix-java-gateway` container:
|
||||
|
||||
```console
|
||||
$ docker exec -ti some-zabbix-java-gateway /bin/bash
|
||||
```
|
||||
|
||||
The Zabbix Java Gateway log is available through Docker's container log:
|
||||
|
||||
```console
|
||||
$ docker logs some-zabbix-java-gateway
|
||||
```
|
||||
|
||||
## Environment Variables
|
||||
|
||||
When you start the `zabbix-java-gateway` image, you can adjust the configuration of the Zabbix Java Gateway by passing one or more environment variables on the `docker run` command line.
|
||||
|
||||
### `ZBX_START_POLLERS`
|
||||
|
||||
This variable is specified amount of pollers. By default, value is `5`.
|
||||
|
||||
### `ZBX_TIMEOUT`
|
||||
|
||||
This variable is used to specify timeout for outgoing connections. By default, value is `3`.
|
||||
|
||||
### `ZBX_DEBUGLEVEL`
|
||||
|
||||
This variable is used to specify log level. By default, value is `info`. The variable allows next values: ``trace``, ``debug``, ``info``, ``want``, ``error``, ``all``, ``off``
|
||||
|
||||
### `ZBX_PROPERTIES_FILE`
|
||||
|
||||
Name of properties file. Can be used to set additional properties using a key-value format in such a way that they are not visible on a command line or to overwrite existing ones.
|
||||
|
||||
### `ZABBIX_OPTIONS`
|
||||
|
||||
Additional arguments for Zabbix Java Gateway. Useful to enable additional libraries and features.
|
||||
|
||||
## Allowed volumes for the Zabbix Java Gateway container
|
||||
|
||||
### ``/usr/sbin/zabbix_java/ext_lib``
|
||||
|
||||
The volume allows include additional JAR files to extend allowed protocols for Zabbix Java Gateway.
|
||||
|
||||
# The image variants
|
||||
|
||||
The `zabbix-java-gateway` images come in many flavors, each designed for a specific use case.
|
||||
|
||||
## `zabbix-java-gateway:ubuntu-<version>`
|
||||
|
||||
This is the defacto image. If you are unsure about what your needs are, you probably want to use this one. It is designed to be used both as a throw away container (mount your source code and start the container to start your app), as well as the base to build other images off of.
|
||||
|
||||
## `zabbix-java-gateway:alpine-<version>`
|
||||
|
||||
This image is based on the popular [Alpine Linux project](http://alpinelinux.org), available in [the `alpine` official image](https://hub.docker.com/_/alpine). Alpine Linux is much smaller than most distribution base images (~5MB), and thus leads to much slimmer images in general.
|
||||
|
||||
This variant is highly recommended when final image size being as small as possible is desired. The main caveat to note is that it does use [musl libc](http://www.musl-libc.org) instead of [glibc and friends](http://www.etalabs.net/compare_libcs.html), so certain software might run into issues depending on the depth of their libc requirements. However, most software doesn't have an issue with this, so this variant is usually a very safe choice. See [this Hacker News comment thread](https://news.ycombinator.com/item?id=10782897) for more discussion of the issues that might arise and some pro/con comparisons of using Alpine-based images.
|
||||
|
||||
To minimize image size, it's uncommon for additional related tools (such as `git` or `bash`) to be included in Alpine-based images. Using this image as a base, add the things you need in your own Dockerfile (see the [`alpine` image description](https://hub.docker.com/_/alpine/) for examples of how to install packages if you are unfamiliar).
|
||||
|
||||
# Supported Docker versions
|
||||
|
||||
This image is officially supported on Docker version 1.12.0.
|
||||
|
||||
Support for older versions (down to 1.6) is provided on a best-effort basis.
|
||||
|
||||
Please see [the Docker installation documentation](https://docs.docker.com/installation/) for details on how to upgrade your Docker daemon.

||||

||||
