watchmen-plugin-googlechatbot

A plugin for watchmen to send message notifications on service events via ChatBot (preferably Google).

Inspired by watchmen-plugin-nodemailer.

Templates

This plugin comes with default templates written in Handlebars for new outages and service back events. Each event has a body template.

You can override templates by copying the included template folder into a new location and specifying this in your environment variables (see below).

Message templates must go in templates/body.

Their filenames should correspond to the watchmen event they're for. For example, templates/body/new-outage.hbs. The plugin will compile all templates when loaded and send email for any body template it loads. This means if you want to send an email for the latency-warning event, simply create a template at templates/body/latency-warning.hbs and restart watchmen.

{{service.name}} ({{service.url}}) is back online after the outage on {{date data.timestamp}}

Templates are passed a service object and a data object. The data object contains the second argument of the event, usually data on the current or last outage. See what the events get passed here: https://github.com/iloire/watchmen/blob/master/README.md#creating-your-own-plugin

Environment variables

The following sample configures the chabot end-point and specifies a custom template directory—overriding the default included templates as explained above.

WATCHMEN_BOT_URI=https://chatbot.example.com/ext/message
WATCHMEN_BOT_TEMPLATE_DIRECTORY=/home/watchmen/templates

Sending Message

This plugin will sent a message with Axios always using POST method to the End-point provided and include the parameter message on the request's body.

Example:

axios.post(process.env.WATCHMEN_BOT_URI, {
    message: sMessage,
})
.then(function (response) {
    console.log("Message sent: ", sMessage);
})
.catch(function (error) {
    messageError();
});
