zbx

Package zbx is a Zabbix Agent implementation in golang that allows your application to act as a zabbix agent and respond to simple requests.

It is compatible with Zabbix version 4 and newer, however it does not support compression and only supports certificate based authentication.

Usage

Basic Agent

This sets up a basic agent with no encryption.

// This function is called for each incoming request from the Zabbix server
getItem := func(itemKey string) (interface{}, error) {
    if itemKey == "agent.ping" {
        return "1", nil
    } else if itemKey == "runtime.version" {
        return runtime.Version, nil
    }

    // Returning nil, nil means the itemKey was unknown
    return nil, nil
}

// This will block
zbx.Start(getItem, "0.0.0.0:10050")

Agent with TLS

This sets up a certificate-based TLS agent. This package doesn't support PSK-based TLS, as crypto/tls does not support this feature, yet.

// This function is called for each incoming request from the Zabbix server
getItem := func(itemKey string) (interface{}, error) {
    if itemKey == "agent.ping" {
        return "1", nil
    } else if itemKey == "runtime.version" {
        return runtime.Version, nil
    }

    // Returning nil, nil means the itemKey was unknown
    return nil, nil
}

// Load the certificate and key that the zabbix agent will use for incoming connections
// from the Zabbix server
cert, err := tls.LoadX509KeyPair("zabbix.crt", "zabbix.key")
if err != nil {
    panic(err)
}

// This will block
zbx.StartTLS(getItem, "0.0.0.0:10050", cert)
