This document discusses the differences between pull-based and push-based monitoring approaches. It notes that both approaches require instrumenting applications, and that sometimes one is easier than the other depending on the situation. Specifically, pull may be easier for monitoring millions of IoT devices globally, while push may be difficult for monitoring metrics from MySQL. The document also thanks Prometheus, the CNCF, and the OpenMetrics initiative for standardizing the pull method and metrics format. It highlights how Kapacitor now integrates Prometheus' service discovery and scraping code to enable pull-based monitoring using InfluxDB.

8. In both cases you need to
instrument your applications.
Sometimes PUSH it easy, in
other cases PULL it’s easy...

9. You can try to pull
from millions of
IoT devices around
the globe

You can always try to push
metrics from mysql
you can try forever!

“The real strength of formalizing the pull method is that it
gives a standard language for services and applications
of all kinds to expose targets with a standard format to
pull metrics data from”
