What is the metrics?

WhaTap collects data from the monitoring targets and provides them to users. The data collected by the agent is marked with metrics.

Metrics provides a baseline for viewing the user environment at a glance. For example, you can easily check the average memory utilization by server and average DB connection time through the list of source data or a visualized chart view. After finding any problem factor, you can see the detailed analysis through logs or traces.

Metrics also helps you scale the user environment. Determining the required amount of resources through the resource usage statistics is important in terms of performance improvement and cost effectiveness.
