Metrics

What is the metrics?​

WhaTap collects data from monitoring targets and provides them to users. The data collected from agents is called metrics.

Metrics consists of the following components:

  • Category: A group of related metrics
  • Tags: Data containing unique identifiers to find the targets to collect
  • Fields: Metrics collected from the agent
  • Time: Time when the metric has been collected
  • Oid: Unique number of the agent that has collected metrics

To view collected data, select a project on the Home screen, and then select Sitemap > Metrics Search.

For example, select a category named db_postgresql_counter and view the related metrics. You can see the (tags) and (fields) that correspond to the category as follows.
