# Zabbix Agent Framework
# Zabbix (Agent) Framework
This tool is used to maintain external zabbix checks in *one place*. There are lot of places where it is possible to download many external checks.
But there is problem with installation, update and centralised management. This tool should do all of this in easy steps. In future it can be *starting point* to
install and configure zabbix agent on systems with one step. Primary goal is not to make all plugins available here but to be able to use any plugin and decentralized development.
If you are maintainer of some external check, it is enough to create zaf file in your repo and use zaf installer everywhere.
Next to this, this tool can even communicate with Zabbix API with *NO dependencies* to high level languages. Shell, sed and awk only.
## Motivation
Did you install lot of zabbix agents and try to setup similar common user parameters? Do you want to setup them all? Do you want to change some zabbix agent options on lot of system? Do you want to write your own simple check or discovery rule for zabbix and it is nightmare to deploy same script on more zabbix agents? Are you tired searching some system specific agent check and setup them individualy?
Did you install lot of zabbix agents and try to setup similar common user parameters? Do you want to setup them all? Do you want to change some zabbix agent options on lot of system? Do you want to write your own simple check or discovery rule for zabbix and it is nightmare to deploy same script on more zabbix agents? Are you tired searching some system specific agent check and setup them individualy? Do you want to auto simple backup all hosts in your zabbix to xml files? Or do you want to do some scripting on host depending on Zabbix server configuration?
So zaf is here for you :)
## Features
@@ -21,56 +23,114 @@ So zaf is here for you :)
* Zabbix discovery simplification. Creating zabbix item for discovery is not so easy in shell based system and result is not nice. But you can use framework function to do so.
* Zabbix agent autoinstallation and autoconfiguration suitable to use in puppet or another tool
* OS packaging support
* Zabbix API support
* Zabbix host autoregistration automation
* Zabbix sender and agent glue (send results of agent checks to zabbix sender)
* Zabbix backup support using [zaf](https://macura.cz/node/34)
* Support for wireless neighbours, clients with autodiscovery [iwx module](https://github.com/limosek/zaf-plugins/tree/master/iwx)
* Support for automated import of hosts and items from [CSV](https://github.com/limosek/zaf-plugins/tree/master/csv)
* Support for fail2ban monitoring [fail2ban](https://github.com/limosek/zaf-plugins/tree/master/fail2ban)
* Supoort for booked [booked](https://github.com/limosek/zaf-plugins/tree/master/booked)
## Roadmap
* External items support with automatic configuration of server
## How it works
Zaf installer will do most of actions needed to monitor some specific plugin items. Configuration of plugin is very simple and text readable. Anybody can write its own plugin or make its plugin "zafable". It is enough to create *control.zaf" file. For example, look into https://github.com/limosek/zaf-plugins repository. This is default repository for zaf.
## I want to make my own plugin!
Great! Look into https://github.com/limosek/zaf-plugins repository, look to control files and try to create your own. It is easy! You can contact me for help.
## I want to help with zaf!
Great! I have no time for testing on systems and writing system specific hacks. Next to this, templates should be optimized and tested for basic plugins.
## I love this tool
OK, great, if you love this tool, you can support new development on paypal account *lukas@macura.cz* or Bitcoin address **19Wbr729vei35gUQLcH2ZJGKb8oTVLz44K**.
## Installing Zaf
**Note**: this instructions are for *trunk* version of zaf. For *stable* version, see https://github.com/limosek/zaf/tree/1.3
**Note**: You can find more examples on [my site](https://macura.cz/search/node?keys=zaf)
You need to be root and you must have curl installed on your system. Depending on your system, github certificates may not be available so you have to use *-k* option for curl (insecure). Default installation type is silent. So there will be no questions and everything will be autodetected. This simple command should be used on most systems:
```
curl -k https://raw.githubusercontent.com/limosek/zaf/1.1/install.sh | sh
curl -k https://raw.githubusercontent.com/limosek/zaf/master/install.sh | sh
```
If you have only wget installed:
```
wget --no-check-certificate -O - https://raw.githubusercontent.com/limosek/zaf/master/install.sh | sh
```
If you do not have https support (like openwrt), I made small http mirror of github files which is synchronized each day:
```
wget -O - http://github.macura.cz/zaf/install.sh| ZAF_RAW_URL=http://github.macura.cz/zaf/ ZAF_URL=http://github.macura.cz/zaf/ ZAF_REPO_URL=http://github.macura.cz/zaf-plugins/ sh
```
### Install options and autoconfiguration
General parameters for install.sh on any system (simplest way how to install)
```
curl -k https://raw.githubusercontent.com/limosek/zaf/1.1/install.sh | \
sh -s {auto|interactive|debug-auto|debug-interactive} [Agent-Options] [Zaf-Options]
curl -k https://raw.githubusercontent.com/limosek/zaf/master/install.sh | \
sh -s {auto|interactive|debug-auto|debug-interactive} [Agent-Options] [Server-Options] [Zaf-Options]
```
or use git version:
```
git clone https://github.com/limosek/zaf.git; cd zaf; git checkout 1.1
./install.sh {auto|interactive|debug-auto|debug-interactive} [Agent-Options] [Zaf-Options]
git clone https://github.com/limosek/zaf.git; cd zaf; git checkout master
./install.sh {auto|interactive|debug-auto|debug-interactive} [Agent-Options] [Server-Options] [Zaf-Options]

Installer will try to autoguess suitable config options for your system.
Now everything was tested on Debian and OpenWrt. If somebody is interrested in, you can help and test with some rpm specific functions. Remember that on some systems, default zabbix agent config is empty so you *need to* enter essential config options as parameters.
### Example
Suppose you want to autoinstall agent on clean system. You need only curl installed. Everything else is one-cmd process.
This command will install zaf, install zabbix-agent if necessary and sets zabbix variables on agent to reach server. This command can be automatized by puppet or another deploying system.

### Installing plugin
### Plugin operations
#### Installing plugin
To install plugin from common repository. If git is available, local git repo is tried first. If not, remote https repo is tried second.
```
zaf install zaf
@@ -153,14 +239,50 @@ zaf install /some/plugin
```
Installer will look into control file, run setup task defined there, fetch binaries and scripts needed for specific plugin and test system dependencies for that plugin. If everything is OK, zaf_plugin.conf is created in zabbix_agentd.d conf directory and userparameters are automaticaly added.
## How it works
Zaf installer will do most of actions needed to monitor some specific plugin items. Configuration of plugin is very simple and text readable. Anybody can write its own plugin or make its plugin "zafable". It is enough to create *control.zaf" file. For example, look into https://github.com/limosek/zaf-plugins repository. This is default repository for zaf.
#### Plugin parameters
Plugin can have some global parameters. For example url of local server to check. See booked plugin. In that case, you have to specify parameters before use.
To set parameters by environment:
```
zaf install booked ZAF_booked_url=http://booked.server/api ZAF_booked_username=user
```
To set parameters later:
```
zaf plugin-set booked url http://booked.server/api
zaf plugin-set booked username user
```
Plugin parameters are available as environment variables in shell script/binary run by agent. You can simulate this environment by
```
zaf itemsh booked.num_reservations
```
Interactive shell will be spawn and you can test your commands or scripts in same way how zabbix agent would do it. Use exit command or ctrl-D to get back.
#### Run plugin subcommand
If plugin is capable of runing subcommand (for example csv plugin), it can be called directly
```
zaf csv send
```
### Agent tests
#### To test result of item (using zabbix_agent -t)
```
zaf test plugin.item[parameters]
```
#### To test result of item (using zabbix_get)
```
zaf test plugin.item[parameters]
```
#### To get result of item directly to stdout
```
zaf run plugin.item[parameters]
```
## I want to make my own plugin!
Great! Look into https://github.com/limosek/zaf-plugins repository, look to control files and try to create your own. It is easy! You can contact me for help.
## I want to help with zaf!
Great! I have no time for testing on systems and writing system specific hacks. Next to this, templates should be optimized and tested for basic plugins.
