18 Script items


Script items can be used to collect data by executing a user-defined JavaScript code with the ability to retrieve data over HTTP/HTTPS. In addition to the script, an optional list of parameters (pairs of name and value) and timeout can be specified.

This item type may be useful in data collection scenarios that require multiple steps or complex logic. As an example, a Script item can be configured to make an HTTP call, then process the data received in the first step in some way, and pass transformed value to the second HTTP call.

Script items are processed by Zabbix server or proxy pollers.


In the Type field of item configuration form select Script then fill out required fields.


All mandatory input fields are marked with a red asterisk.

The fields that require specific information for Script items are:

Field Description
Key Enter a unique key that will be used to identify the item.
Parameters Specify the variables to be passed to the script as the attribute and value pairs.
User macros are supported. To see which built-in macros are supported, do a search for "Script-type item" in the supported macro table.
Script Enter JavaScript code in the block that appears when clicking in the parameter field (or on the view/edit button next to it). This code must provide the logic for returning the metric value.
The code has access to all parameters, it may perform HTTP GET, POST, PUT and DELETE requests and has control over HTTP headers and request body.
See also: Additional JavaScript objects, JavaScript Guide.
Timeout JavaScript execution timeout (1-600s; exceeding it will return an error).
Note that depending on the script, it might take longer for the timeout to trigger.
For more information on the Timeout parameter, see general item attributes.


Simple data collection

Collect the content of

  • Create an item with type "Script".
  • In the Script field, enter:
var request = new HttpRequest();
       return request.get("");
Data collection with parameters

Collect the content of a specific page and make use of parameters:

  • Create an item with type "Script" and two parameters:
    • url : {$DOMAIN} (the user macro {$DOMAIN} should be defined, preferably on the host level)
    • subpage : /release_notes

  • In the Script field, enter:
var obj = JSON.parse(value);
       var url = obj.url;
       var subpage = obj.subpage;
       var request = new HttpRequest();
       return request.get(url + subpage);
Multiple HTTP requests

Collect the content of both and

  • Create an item with type "Script".
  • In the Script field, enter:
var request = new HttpRequest();
       return request.get("") + request.get("");

Add the "Log test" entry to the Zabbix server log and receive the item value "1" in return:

  • Create an item with type "Script".
  • In the Script field, enter:
Zabbix.log(3, 'Log test');
       return 1;
