Whether the ZABBIX monitoring host is online

A little busy recently , I haven't updated my blog for a long time . Today's article mainly records how to pass zabbix Monitor whether a host is online .

All right, let's go .

1. Create a new template

The purpose of creating a new template is to add “ Monitoring item ” and “ trigger ” Of , If the number of hosts you want to monitor is very small , Of course, there is no need to create a new template , Instead, add directly to the host to be monitored “ Monitoring item ” and “ trigger ”. But if you want to monitor a very large number of hosts, it will be a bit laborious , Why don't you just “ Monitoring item ” and “ trigger ” Built on the template , In this way, the host you want to monitor only needs to apply the template you have created .

Log in first zabbix Configuration management page of , Locate the “ To configure —- Templates ” page , Click... In the upper right corner of the page “ Create a template ”, Follow the figure below , After filling in the required items of the template , Click on “ add to ” The button creates a new one named “MyTemplate” The template , Next, we will continue to add... To this custom template ” Monitoring item “ and ” trigger “.

2. To add a monitor item to a custom template

Still “ Templates ” Page quickly navigate to the newly created template by searching .

Enter the template details page , choice “ Monitoring item ” tab , Then click... In the upper right corner of the page “ Create monitor item ” Button , Add a new one “ Monitoring item ”.

Fill in the required contents of the monitoring item , Click on “ add to ” Button , A new monitoring item is created for the custom template , The host using this set of templates can collect data through this monitoring item .

3. New trigger

Still “ Templates ” page , Click on “ trigger ” tab , Click on the “ Create trigger ” Button , Add a trigger for the custom template .



After the above operations are completed , You should also add a dependency to this trigger . You can think about it , Our monitoring item is a simple check , That's one ping command , If the host is not online, the trigger created according to the above will always be in the trigger state , Obviously this is a little out of common sense . We can solve this problem by adding dependencies .

Added in the above figure “zabbix agent is not available” The trigger is also a trigger to monitor whether the host is online , But it didn't icmping So sensitive , If opened “zabbix agent is not available” trigger , You can check its details , If “zabbix agent is not available” Trigger condition of trigger terminated , Then the trigger conditions that depend on it also terminate , In this way, the trigger is automatically closed .

4. Create a new trigger action

After the previous preparations, we can create a new trigger action , When the host is down, you can use e-mail or staples webhook A notification alarm has been given .

Get into “ action —-Trigger actions” page , Click on the top right corner of the page ” Create action “ Button , Add an action .


Next, add an action item to the action .

5. Apply custom templates

Okay , Now everything is ready , Next, you can apply the custom template to the host to be monitored .

Enter the host page in the configuration page , Click the host link to enter the host configuration details page .


By doing this , Add a custom template for the host .

6. test

Shut down the engine , Test triggers 、 Whether the trigger action works normally .

The alarm email has been received normally , thus zabbix The operation of monitoring host downtime is completed .
