Zabbix agent 2

Zabbix agent 2 is a new generation of Zabbix agent and may be used in place of Zabbix agent. Zabbix agent 2 has been developed to:. Agent 2 is written in Go with some C code of Zabbix agent reused. A configured Go version 1. Passive checks work similarly to Zabbix agent. Checks from different plugins can be executed concurrently. The number of concurrent checks within one plugin is limited by the plugin capacity setting.

Each plugin may have a hardcoded capacity setting being default that can be lowered using the Plugins. Zabbix agent 2 is available in pre-compiled Zabbix packages. To compile Zabbix agent 2 from sources you have to specify the --enable-agent2 configure option. The configuration parameters of agent 2 are mostly compatible with Zabbix agent with some exceptions.

You may use this option to specify a configuration file that is not the default one. Note : To return user parameter results as well, you must specify the configuration file if it is not in the default location. Use this option with -p and -t options. This option is supported since Zabbix 4. See runtime control. Runtime control provides some options for remote control.

Option Description loglevel increase Increase log level.

New parameters Description ControlSocket The runtime control socket path. Agent 2 uses a control socket for runtime commands. Plugins Plugins may have their own parameters, in the format Plugins. A common plugin parameter is Capacitysetting the limit of checks that can be executed at the same time. StatusPort The port agent 2 will be listening on for HTTP status request and display of a list of configured plugins and some internal parameters Dropped parameters Description AllowRootUser Not supported because daemonization is not supported.

StartAgents This parameter was used in Zabbix agent to increase passive check concurrency or disable them. In Agent 2, the concurrency is configured at a plugin level and can be limited by a capacity setting.

Whereas disabling passive checks is not currently supported.Zabbix Agent is a process that runs on remote machines, which need to monitory through the Zabbix server. The agent collects the data on the remote server and provides to Zabbix server on requests on periodically.

After installing zabbix server on your system. After completing this step go to next article add Host in Zabbix Server. It is a good idea to disable the SELinux to work Zabbix properly. By default, Zabbix is not available in the CentOS 8 default repository. So you will need to install the Zabbix repository in your system. At the time of writing this tutorial, the latest version of Zabbix is Zabbix 4.

You can install the Zabbix 4. After installing yum repository packages in our system. Once the installation is completed, start the Zabbix agent service, and enable them to start after system reboot with the following command:. Now, you need to configure the Agent service to allow Zabbix server requests. Edit the Zabbix agent configuration file by adding the Zabbix server IP.

More than that, it is less complicated than C Loadable modulesso creating plugins is now much more accessible for everyone. At Zabbix Summitbesides introducing Zabbix 4. What makes it different from its predecessor is that now developers can write Zabbix plugins in Go.

What would such a plugin look like? Where can we find examples and documentation? If you ever tried or wanted to write a plugin for the first Zabbix Agent, you might have noticed that there are quite a few limitations. Using persistent connections, saving the states of monitored components between checks, and receiving SNMP traps was either difficult or impossible to implement.

Zabbix Agent 2 has a completely different architecture. It is written from scratch in Go, with some reused code in C from the first Zabbix Agent, so developing plugins became much easier, in comparison to developing them in C. Moreover, the Go Agent is backwards-compatible with the classic Zabbix Agent in terms of the protocol, configuration and metrics.

The new agent is available in Zabbix 4. Keep in mind that the following information is for Zabbix 4. Given that the Go Agent is an experimental feature, some of it might be inapplicable by the time Zabbix 5. There is one Connector per active server. ServerListener accepts passive check requests from the server and then sends them to Scheduler.

Scheduler manages the task queue according to the schedule and concurrency settings. The Go Agent launches a single Scheduler to manage tasks plugins in accordance with the schedule defined by item settings. We can look at the inner structure of the agent in terms of active and passive checks bulk passive checks are coming soon. Keep in mind that we differentiate between these two types only to demonstrate how the agent works, because both technically share the same components.

The schemes below illustrate component interaction for each check type.

For each active server we create ServerConnector and ResultCacheboth launched in its own goroutine. Classic passive checks also use Scheduler to manage tasks. However, it receives item configurations from ServerListener instead of ServerConnector. After receiving item configuration from Zabbix server, ServerConnector updates its own data and creates a specific updateRequest for each plugin that provides corresponding metrics.Zabbix agent is deployed on a monitoring target to actively monitor local resources and applications hard drives, memory, processor statistics etc.

Part 2 : How to Install Zabbix Agent 3.0 and Add Windows Host to Zabbix Monitoring

The agent gathers operational information locally and reports data to Zabbix server for further processing. In case of failures such as a hard disk running full or a crashed service processZabbix server can actively alert the administrators of the particular machine that reported the failure. Zabbix agents are extremely efficient because of use of native system calls for gathering statistical information.

In a passive check the agent responds to a data request. Zabbix server or proxy asks for data, for example, CPU load, and Zabbix agent sends back the result. Active checks require more complex processing. The agent must first retrieve a list of items from Zabbix server for independent processing. Then it will periodically send new values to the server. Whether to perform passive or active checks is configured by selecting the respective monitoring item type. Zabbix agent processes items of type 'Zabbix agent' or 'Zabbix agent active '.

See the package installation section for instructions on how to install Zabbix agent as package. Alternatively see instructions for manual installation if you do not want to use packages. If the above does not work you have to start it manually. Zabbix agent is distributed as a zip archive. After you download the archive you need to unpack it.

Choose any folder to store Zabbix agent and the configuration file, e. See more details on installing and running Zabbix agent on Windows. It is possible to run multiple instances of the agent on a host. A single instance can use the default configuration file or a configuration file specified in the command line. In case of multiple instances each agent instance must have its own configuration file one of the instances can use the default configuration file.

Zabbix agent on UNIX is designed to run as a non-root user. It will run as whatever non-root user it is started as. So you can run agent as any non-root user without any issues. If you will try to run it as 'root', it will switch to a hardcoded 'zabbix' user, which must be present on your system. You can only run agent as 'root' if you modify the 'AllowRoot' parameter in the agent configuration file accordingly.

Note that the agent requires a UTF-8 locale so that some textual agent items can return the expected content. Most modern Unix-like systems have a UTF-8 locale as default, however, there are some systems where that may need to be set specifically.

The requests are sent to Scheduler through a channel, then Scheduler creates tasks and puts them in the queue.Following previous tutorials concerning Zabbix series, this article describes how to install and setup an instance of Zabbix agent to run as a service on Microsoft Windows systems in order to monitor your infrastructure windows environments, especially server machines.

The pre-compiled zip agents for Windows environments can be obtained from official Zabbix download page and manually installed and started on the system using windows Command Prompt as in the following example:.

To stop the service run the same command as above with --stop argument and to uninstall the service use the --uninstall argument. Once the Zabbix agent msi file has been downloaded on your system, run it and supply the required information in order to configure and install the agent on the target monitored host as it follows:.

Almost all Windows based systems have Windows Firewall active and running, therefore zabbix agent port must be opened in firewall in order to communicate with zabbix server. Next, click on Allow another app button and a new window should open. Next, make sure you check and open the firewall rule on the network segment where zabbix server is located in your network and hit OK button to finish and apply configuration.

In order to test if Zabbix agent running on windows is reachable from Zabbix server side, use telnet or netcat command on zabbix server against windows agent IP-Port and a Connected message should appear. Hit Enter key to generate an error message and automatically disconnect from agent:. On Host window add the FQDN of your windows agent machine in Host name filed, add an arbitrary name to Visible name filed in order to easily identify the monitored machine on Zabbix panel, make sure the host is included into a Group Servers and add the IP Address of your windows host in Agent interfaces filed.

The Port value leave it unchanged. Next, go to Template tab and hit on Select button. A new window with Zabbix Templates should appear. Navigate through this window, check Template OS Windows and hit on Select button to add the template. Once the Template OS Windows appears on Link new templates filed, hit on Add button in order to link this template to the windows host configuration.

Finally, after the Template OS Windows is visible in Linked Templates filed hit on below Add button to complete the process and add the entire Windows host configuration. Just assure that your windows host Status is set to Enabled and wait a few minutes in order for Zabbix server to contact the windows agent side and process the received remote data.
