Docs

Welcome to the docs. Not docks, no docker yet.

Usage

Extensions

First, find some extensions. You'll need a checker to check whether something is up, a logging extension to log stuff, and optionally an extension to send alerts. Extensions are specified on a per-service basis, so you can mix-and-match extensions as much as you want. Once there are some real extensions I'll list some here.

Config

Then create a services.json file for your config, like this:

{
    "global-args": {
        "default-checker": "CheckerTemplate",
        "default-alerts": "AlertsTemplate",
        "default-logging": "LoggingTemplate"
    },
    "site": {
        "name": "A Website",
        "checker": "HttpChecker",
        "checker-args": {
            "url": "https://example.com"
        },
        "rate": 1,
        "alerts-args": {
            "url": "https://example.com/webhook-url-or-whatever-goes-here",
            "lol": "irrelevant, AlertsTemplate ignores these options lol"
        },
        "logging-args": {
            "file": "/home/askiiart/Documents/updog/logs/site-log"
        }
    }
}

Global config

Optional arguments:

• default-checker: The default checker for all services, can be overriden per-service using checker
• default-alerts: The default alerter extension for all services, can be overriden per-service using alerts
• default-logging: The default logging extension for all services, can be overriden per-service using logging

Service config

Required arguments:

• The key (in this case site): A unique string to identify the service in logs, also used internally.
• checker: The name of the checker extension's class - optional if default-checker is specified in the global arguments.
• checker-args: Arguments for the checker. Check the checker's docs for what to put here.
• rate: How often to check if the service is up (every x seconds)
• alerts: The name of the alerting extension's class - optional if default-alerts is specified in the global arguments.
• alerts-args: Arguments for the alerting extension. Check the alerter's docs for what to put here.
• logging: The name of the logging extension's class - optional if default-logging is specified in the global arguments.
• logging-args: Arguments for the logging extension. Check the logger's docs for what to put here.

Optional arguments:

• name: A human-friendly name for the service; currently unused.

---

This example uses the template extensions, askiiart/updog-checker_template, askiiart/updog-logging_template, and askiiart/updog-alerts_template, so the arguments for them are mostly irrelevant. For each extension, check its docs for what arguments to use.

Running it

Just run it with python3 updog.py

Docker

No Docker yet, Updog throws RuntimeError: can't create new thread at interpreter shutdown when I try to run it in Docker. So no Docker until I figure that out.
