Simplest way to push metrics with curl?

cantino · March 22, 2023, 5:08am

I just signed up for Grafana Cloud. I want a very simple setup to monitor some shell scripts and periodic processes: curl → grafana cloud → alerts. I’m aware that Grafana itself doesn’t receive pushed metrics, but I think something else in the Grafana Cloud offering does. What’s the absolute simplest way for me to get periodic metrics via curl into the hosted platform? (I was using stathat previously, but it’s been unstable.)

Welcome @cantino
What is the typical output from your curl?
Do you have any desire to store your information so you can go back and view it, or are you already doing that?

Hello @cantino – my colleague and I published this blog post which contains a working cURL example of pushing metrics to Grafana Cloud’s hosted Mimir database:

#!/usr/bin/bash
API_KEY="<user_id>:<api-key>"
URL="https://[...].grafana.net/graphite/metrics"

curl -X  POST -H  "Authorization: Bearer $API_KEY" -H  "Content-Type: application/json" "$URL" -d '[{
        "name": "test.metric",
        "interval": 10,
        "value": 12.345,
        "tags": ["foo=bar", "source=grafana_cloud_docs"],
