Zabbix API Client for NodeJS And Browsers

This is a Zabbix API Client for NodeJS and Browsers written in Typescript to interact with a Zabbix Server using the API methods.

Getting started

Install this lib with npm:

npm install --save @fjedi/zabbix-client

All parameters used within this lib can be found in the Zabbix API documentation itself.

Parameters like jsonrpc, id and etc are abstracted within this lib.

Usage examples

Creating the object then logging in:

const { ZabbixClient } = require("@fjedi/zabbix-client");

// No calls are made here yet
const client = new ZabbixClient("http://company.com/zabbix/api_jsonrpc.php");

// A token will be fetched and saved for further use
const api = await client.login("theusername", "thepassword");

After the login, we get an api object which is an instance of ZabbixAPI class that enables us to call other zabbix methods as we wish, you can find all methods in the Zabbix API Methods reference.

Let's get the api info:

const { ZabbixClient } = require("@fjedi/zabbix-client");

const client = new ZabbixClient("http://company.com/zabbix/api_jsonrpc.php");

const api = await client.login("theusername", "thepassword");
// To enable relogin: client.login("theusername", "thepassword", true);

const allHosts = await api.method("host.get").call();

// The version info needs an unauthenticated user, you
// can disable the token sending using the second parameters
// like the following
const version = await api.method("apiinfo.version").call({}, false);

console.log(version); // 4.0.0

The raw response from zabbix is abstracted and only the result is returned by the call method.

In case we need to call a method and send params with it (example taken from this zabbix documentation page):

const hosts = await api.method("host.create").call({
    host: "Linux server",
    interfaces: [
        {
            type: 1,
            main: 1,
            useip: 1,
            ip: "192.168.3.1",
            dns: "",
            port: "10050"
        }
    ],
    groups: [
        {
            groupid: "50"
        }
    ],
    templates: [
        {
            templateid: "20045"
        }
    ],
    macros: [
        {
            macro: "{$USER_ID}",
            value: "123321"
        }
    ],
    inventory_mode: 0,
    inventory: {
        macaddress_a: "01234",
        macaddress_b: "56768"
    }
});

console.log(hosts); // { hostids: ["107819"] }

In case of an error during the call, an instance of ZabbixResponseException will be thrown, so if you are using async/await, you can catch it like this:

try {
    const result = api.method("thismethod.doesnotexist").call();
} catch (err) {
    err instanceof ZabbixResponseException; // true
    console.log(err.message); // Incorrect method "thismethod.doesnotexist"
}

// It is also thrown if login fails
try {
    const api = client.login("wrongusername", "wrongpassword");
} catch (err) {
    err instanceof ZabbixResponseException; // true
    console.log(err.message); // Login name or password is incorrect.
}

Or else, just do a then/catch:

api.method("thismethod.doesnotexist")
    .call()
    .then(result => {
        // the result, but this will fail
    })
    .catch(err => {
        err instanceof ZabbixResponseException; // true
        console.log(err.message); // Incorrect method "thismethod.doesnotexist"
    });

Note

Remember to always logout after you finish using the api:

await api.logout();
