Introduction

OLP generates operational logs and metrics that you can use to keep track of your processes and usage. You can also configure certain conditions to trigger notifications from both your catalogs and pipelines, and you can log your own messages from within your pipelines.

There are three tools involved in logging and metrics:

  • Splunk - Use this tool for viewing and searching logs.
  • Grafana - Use this tool for viewing metric data on dashboards. OLP comes with standard regional dashboards and you can also create your own custom dashboards and alerts.
  • Prometheus - A data collection agent that stores metrics pushed from the pipeline and data services, saving it in a time-series database that can then be used by Grafana dashboards.

Note: Prometheus database

Prometheus only retains data from the previous 30 days. This means that Grafana will not be able to access data over 30 days old.
