chartsrv
chartsrv is a dead-simple web application which runs Prometheus queries and
charts the result as an SVG. You make a dashboard by putting a lot of these
images into a web page. You make it refresh by adding
<meta id="refresh" http-equiv="refresh" content="5"> to the header. Ta-da!
This is a live graph from metrics.sr.ht
Running the daemon
$ go build -o chartsrv main.go $ ./chartsrv https://prometheus.example.org Listening on :8142
Forward /chart.svg to this address with your favorite reverse proxy. If you
want to listen to some other port, pass a second argument like :1337.
Usage
Create a URL like https://chartsrv.example.org/chart.svg?query=...&args... and
set the query parameters as appropriate:
- query: required. Prometheus query to execute.
- title: chart title
- stacked: set to create an area chart instead of a line chart
- since: time.ParseDuration to set distance in the past to start charting from
- width, height: adjust chart dimensions in inches
- step: number of seconds between data points
- min, max: Y axis limits
