Understanding Cardinality in a Monitoring System and Why It's Important
The journey to becoming cloud-native comes with great benefits but also brings challenges.

The increased number of data sources does not only increase datapoint volume – it also requires that monitoring systems store and query against data with higher cardinality than ever before.
