Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Monitoring with Custom Metrics
In case the Custom Metric is related to a job or a short-living script, consider using Pushgateway.

Bucketed data from jenkins?
So my idea is to have a python script that buckets data and then publishes it again using pushtogateway: https://github.com/prometheus/pushgateway

The right tool for pulling data from random via REST API.
Is the cron job with a script for getting metric and pushing via https://github.com/prometheus/pushgateway the right way for this task?

On the Prometheus Push Gateway
The push gateway is a relatively simple service. There’s one main entry point file (main.go) and an api file (api.go) both at 279 lines log. There’s probably a dozen or so api endpoints, but the key one is the one where you post metrics, defined here

"The Pushgateway is not an event store. [...] tracking something like release events has to happen with some event-logging framework."
We are currently evaluating timeseries databases to build an internal tool for DORA metrics and just looking at prometheus. As tracking releases is more of a push based use case, I looked at pushgateway and the docs stated the following "The Pushgateway is not an event store. [...] tracking something like release events has to happen with some event-logging framework." here

Ask HN: Prometheus vs. StatsD / Telegraf
While I somehow understand Prometheus idea that pull is easier to scale than push I've had a bad luck with it.
First of all Prometheus doesn't even consider monitoring of long-running jobs other than pull way (which didn't make sense for me). There is push gateway [0] but clients libraries seem to consider it only for short-lived jobs where you can send the metrics at the end [1]. It seems I couldn't "push" from long living jobs trivially
Second when using it for example with django you have to be careful with how you handle multiprocessing that UWSGI/gunicorn does, see [2] - it has bitten me at leas once.
Comparing to push model where I can just push metrics to [3] statsd_exporter directly and be done with it, but support for statsd is lacking both in terms of frameworks (everyone seems to be migrating to native clients...) and functionality (you've to do labeling basically manually [4])
To sum up: Prometheus is really great when it works, until you try to go off-track (intentionally or not, see django [2]) then you see its all undiscovered and immature landscape

Optimizing Performance Using Prometheus with Node JS for Monitoring
However, for this tutorial, the Prom-client package will be used as it has user-friendly documentation, a large user base and strong community support. Here is a link to its documentation and npm page.

How to collect metrics from node.js applications in PM2 with exporting to Prometheus
This approach will work as long as you don’t need to run multiple instances of the application in cluster mode. For collecting metrics in cluster mode, prom-client provides a good example with metric aggregation. But what if you’re running the application through the process manager PM2, where you don’t have access to the running cluster?

Trying to Monitor and Alert on Process Downtime for Azure Linux VMs
You would need to build a custom endpoint if it's a custom application that Prometheus can scrape but there are many libraries for that like prom-client for NodeJS or prometheus-net for C#. The list of client libraries can be found here.

Avoiding "No data" stat panel state
The metric itself is process_start_time_seconds (from the prom-client NodeJS package), which returns the timestamp in seconds corresponding to the start time of the process.

Monitoring consumer lag in Azure Event Hub
Consumer lag will quickly show any functional or technical issue with your event stream. By using the code examples from this blogpost, you can avoid having to dive into the SDKs yourself. Of course, you can adopt the metric collection to send the metric to the logs or to another metrics system like prometheus, datadog, or open telemetry.
