How to Update

Docker

Re-pull the latest docker image and create another container with the same volume.

PS: For every new release, it takes some time to build the docker image, please be patient if it is not available yet.

Without Docker

git fetch --all
git checkout 1.0.6 --force
npm install
npm run build
pm2 restart uptime-kuma

Passing metrics to other platforms

If you already use Prometheus.io or a platform that supports Prometheus exporter format, you can get the metrics about each monitoring target from http://<your.installation>:<your_port>/metrics.

Labels to filter by include:

| Label Name | Description | +------------+-------------+ |monitor_name| The "Friendly Name" of the monitor | |monitor_type| The type (HTTP, keyword, TCP) of monitoring check | |monitor_url | The URL to be monitored (HTTP, keyword) |monitor_hostname | The Hostname to be monitored (TCP) | |monitor_port | The port to be monitored (TCP) |

Example PromQL queries

Assuming we have HTTP monitors in place for bbc.co.uk and google.com:

# Show all response rates gouped by site
sum(monitor_response_time) by (monitor_name)

# Show only the response time for BBC.co.uk
sum(monitor_reponse_time{monitor_url="https://www.bbc.co.uk/"})

# Show the current status of Google.com
monitor_status{monitor_name="Google"}

Motivation

• I was looking for a self-hosted monitoring tool like "Uptime Robot", but it is hard to find a suitable one. One of the close one is statping. Unfortunately, it is not stable and unmaintained.
• Want to build a fancy UI.
• Learn Vue 3 and vite.js.
• Show the power of Bootstrap 5.
• Try to use WebSocket with SPA instead of REST API.
• Deploy my first Docker image to Docker Hub.
