Zabbix Agent 6.2.6 Download
Isidora Herline
I want to use Zabbix to monitor my server (just one so far). In order to keep things neat, I've decided to run it in Docker containers. I just have doubts about the usage of the agent in a container. As far as I understand it should be able to monitor the host itself. But containers are usually isolated. So what's the point to run the agent in the container?
Use this IP for the Agent's interface in the Zabbix server's web interface. As you've rightly remarked, since the agent runs in a container, it's isolated and the default IP pf 127.0.0.1 won't work: you need a routable IP for the Zabbix Server to reach the Agent on.
You can run a single instance of Zabbix agent or multiple instances of the agent on a Microsoft Windows host. A single instance can use the default configuration file C:\zabbix_agentd.conf 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).
To perform active checks on a host Zabbix agent needs to have the hostname defined. Moreover, the hostname value set on the agent side should exactly match the "Host name" configured for the host in the frontend.
The hostname value on the agent side can be defined by either the Hostname or HostnameItem parameter in the agent configuration file - or the default values are used if any of these parameters are not specified.
The default value for HostnameItem parameter is the value returned by the "system.hostname" agent key. For Windows, it returns result of the gethostname() function, which queries namespace providers to determine the local host name. If no namespace provider responds, the NetBIOS name is returned.
The default value for Hostname is the value returned by the HostnameItem parameter. So, in effect, if both these parameters are unspecified, the actual hostname will be the host NetBIOS name; Zabbix agent will use NetBIOS host name to retrieve the list of active checks from Zabbix server and send results to it.
Host name is also used as part of Windows service name which is used for installing, starting, stopping and uninstalling the Windows service. For example, if Zabbix agent configuration file specifies Hostname=Windows_db_server, then the agent will be installed as a Windows service "Zabbix Agent [Windows_db_server]". Therefore, to have a different Windows service name for each Zabbix agent instance, each instance must use a different host name.
Zabbix agent for Windows does not support non-standard Windows configurations where CPUs are distributed non-uniformly across NUMA nodes. If logical CPUs are distributed non-uniformly, then CPU performance metrics may not be available for some CPUs. For example, if there are 72 logical CPUs with 2 NUMA nodes, both nodes must have 36 CPUs each.
By default, after a restart, Zabbix agent 2 will schedule the first data collection for active checks at a conditionally random time within the item's update interval to prevent spikes in resource usage. To perform active checks that do not have Scheduling update interval immediately after the agent restart, set ForceActiveChecksOnStart parameter (global-level) or Plugins..System.ForceActiveChecksOnStart (affects only specific plugin checks) in the configuration file. Plugin-level parameter, if set, will override the global parameter. Forcing active checks on start is supported since Zabbix 6.0.2.
To install the Zabbix agents in our Openshift Cluster, we will use the Zabbix Operator. In this scenario, we will use the agent installation via operator and configure it to send the collections to an external Zabbix Server. The diagram shows how it will work the data flow from Openshift to Zabbix
This ZenPack unlocks Zabbix agent functionality for Zenoss. The best benefit is that Zabbix agent is available for wide range of OS (UNIX, Windows, ...). Default Zabbix templates adapted for Zenoss are included.
In this example, we create on localhost a MariaDB database called zabbix for the user zabbix identified by the password test and then import the database templates. This connection will be later used by the Zabbix server and web application.
You have to restart zabbix-agentd to apply the new configuration. The keyword for the item you later use in the web frontend is archlinuxupdates. It returns an integer representing the count of available updates.
Following previous tutorials concerning the Zabbix series, this article describes how to install and set up an instance of a Zabbix agent to run as a service on Microsoft Windows systems in order to monitor your infrastructure windows environments, especially server machines.
1. The pre-compiled zip agents for Windows environments can be obtained from the official Zabbix download page and manually installed and started on the system using windows Command Prompt as in the following example:
4. A second and more convenient method to install and automatically configure the Zabbix agent on Windows environments is by downloading the Zabbix Agent installer MSI package specific to your system architecture.
5. 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:
7. Almost all Windows-based systems have Windows Firewall active and running, therefore Zabbix agent port must be opened in the firewall in order to communicate with the Zabbix server.
8. Next, click on Allow another app button and a new window should open. Use the Browse button to navigate and add Zabbix agent executable file (usually found in %programfiles%\Zabbix Agent\ if you installed it using MSI program), then hit on Add button to add the service.
10. In order to test if the Zabbix agent running on windows is reachable from the 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 the agent:
11. Once the windows agent has been tested from the command line and everything looks fine, go to Zabbix Server web interface, move to Configuration tab -> Hosts, and hit on Create Host button in order to add the Windows monitored host.
12. On the Host window add the FQDN of your windows agent machine in Hostname 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 in a Group Servers, and add the IP Address of your windows host in Agent interfaces filed. The Port value leaves it unchanged.
I am using HyperV on this server and have a virtual network that is connected to the virtual switch. Zabbix agent is trying to get information from my physical network on the server, and not from the virtual network that has all required information for the network (IP, DNS.. etc)
I wish the better for you! This tutorial helps me a lot! I was trying for days to enable agent on windows for my zabbix and I lost a little, but very important configuration: Choose a template for station. I searched a lot (on Zabbix Manual too) and I only found here! And now it works!
I am installing Zabbix on Ubuntu Serve 16.04. I can install everything. when I add new windows host, got some error like ERROR: Cannot add host, Incorrect arguments passed to function.. I have installed zabbix-agentd on windows and pointing to the correct ip address of Zabbix server.
I followed the guide, added success windows server into zabbix to monitor. guys after added server please reload the zabbix services and wait for whole configuration is reloaded in back end it may be take 5 min or more..
Hello , Experts,
Need some help from zabbix experts. I'm not getting message on telegram when Zabbix agent is not available. All other problem messages on telegram is working fine.
Am I missing something ? Do I need to create a special template to a capture unavailability of zabbix agent.
I tried looking at solution on zabbix fourm. The closet match was

but it was not helpful
My zabbix_agentd.conf look as below
Different monitored systems/devices and checks can return non-ASCII characters in the value. For such cases, almost all possible zabbix keys contain an additional item key parameter - . This key parameter is optional but it should be specified if the returned value is not in the UTF8 encoding and it contains non-ASCII characters. Otherwise the result can be unexpected and unpredictable.
If a value contains a non-ASCII character in non UTF8 encoding - this character and the following will be discarded when the database stores this value. No warning messages will be written to the zabbix_server.log.
Relevant for at least MySQL version 5.1.61
If a value contains a non-ASCII character in non UTF8 encoding - this will lead to a failed SQL query (PGRES_FATAL_ERROR:ERROR invalid byte sequence for encoding) and data will not be stored. An appropriate warning message will be written to the zabbix_server.log.
Relevant for at least PostgreSQL version 9.1.3
