See: https://prometheus.io/docs/instrumenting/clientlibs/
Choose your programming language, write your exporter using the prometheus client library for that language. There are various tutorials, e.g. https://prometheus.io/docs/guides/go-application/ At the end of the day, an exporter is just a HTTP server that returns a response body containing prometheus metrics exposition format <https://prometheus.io/docs/instrumenting/exposition_formats/>. The client libraries can just make things a little easier, e.g. maintaining counters for you. Some alternative approaches you could also consider: - use node_exporter's textfile collector. Then you just need to write metrics to a file, and node_exporter will pick them up automatically. - use exporter_exporter <https://github.com/QubitProducts/exporter_exporter>, which is able to exec a script - use one of the other generic exporters like statsd_exporter or pushgateway, and write your metrics to that (where they will persist, waiting for prometheus to scrape them) On Thursday, 21 April 2022 at 16:36:30 UTC+1 deeshu...@gmail.com wrote: > How to write Custom - exporter for specific application?
