Zabbix templates + Network Discovery

Template Introduction

Template is a set of configuration, it can be easily deployed quickly on a monitoring object, and support repeated application, when the template is applied to a host, all its defined entries are automatically added, the other advantage of the template is that, if necessary, modified template, the application of the host will be modified accordingly.

what can be defined in the template: app set (application), Project (item), Trigger (trigger), graphics (graph), screen, Discovery Rule (discovery), web

Template Creation

Create a template: Click Create template in the configuration--templates

Define a template, create a template name and associate a group.

The template definition is complete and the host list is the same, you can create the project trigger directly above, etc.

Define two monitoring items on the template to monitor memory used space and total space

and add graphics to the stencil

Template creation, you can see the template created two monitoring items, a graphic any use of this template will automatically create these two monitoring items and graphics

Auto Discovery

Auto-Discovery is one of the most characteristic features of Zabbix, he can automatically add monitoring host or service according to the rules defined by user, accelerate Zabbix deployment and simplify management operation of OPS personnel.

Zabbix's network discovery capabilities can be based on the following information:

(1) Scan the specified IP address range

(2) HTTP, ICMP, SSH, LDAP, TCP, SNMP, Telnet, zabbix_agent scan the host within the specified network;

The discovery rule consists of two stages discovery and actions:

Discovery: periodically scans the host for the specified network segment, and once the host is found triggering the following event

Events in Discovery:

The action performed:

Sending Notifications #发送通知

Adding/removing hosts #添加删除主机

Enabling/disabling hosts #启用禁用主机

Adding hosts to a group #将主机添加到组中去

Removing hosts from a group #从组中移除主机

Linking hosts to/unlinking from a template #链接模版到主机, deleting links

Executing Remote scripts #执行远程脚本

interface Add: interface is automatically created when added in Network discovery, for example, if the SNMP-based detection succeeds, the SNMP interface is created

(1) If a service responds to both agent and SNMP at the same time, both interfaces will create

(2) If the same discovery mechanism (such as agent) returns non-unique data, the first interface is recognized as the default, and the other is the additional interface

(3) Even if a host started with only the agent interface, and later found it through SNMP, it will also add additional SNMP interface

(4) different hosts if the same data is returned, the first host will be added and the remaining host will be treated as an additional interface for the first host

Example: automatic discovery Implementation

Add a host to the network, IP address 172.16.4.102, host name Node3

Set the rule: Define an IP address range here, check the way is ping, as long as you can ping to find the host.

At this point, you'll see the Autodiscover host in the event.

Create an action that automatically joins the Autodiscover host to the monitor, where you need to select the event source to explore before creating the action

After a while, the data is collected and the graphics are generated.

Automatic Registration

proactively discovering weaknesses: If the defined scan time is short, then the performance impact too much, if the time is too long, then the discovery is not very timely, in this case, you can use the automatic registration function.

Autoenrollment can also be used for scenarios where the failed agent is back online.

Configure Auto-Enrollment

Before setting, disable the Autodiscover rule and explore action, and go online with a node4 host (172.16.4.103)

Define the conditions for registration, as long as the host name and node are similar, and the host metadata and Artest are similar to complete autoenrollment

Set up how host autoenrollment handles: Join an autoenrollment host to a Test_group host group, and apply the hosts template that you started to create

Verify the configuration: If you cannot register immediately after the setup is completed, you can restart the Node4 zabbix-agent service to complete the registration immediately.
