2 second resolution

Metrics are collected every 2 seconds. Data available for query instantly after collection. No extra processing time. No need for intermediary satellite agents.
Here is a chart showing metrics collected at different resolutions:
For comparison:
2-second resolution data is:

No processing delay

The metrics are available for processing right at the time of collection, without any extra seconds of delay. This is especially important for monitoring data since you want to know in real time what is happening in your infrastructure, without delay.

Some vendors like SignalFx and Instana claim 1 second resolution, but take many additional seconds after collection to make it available for querying and display. This effectively lowers the data resolution many times over.
