How to monitor Redis with Prometheus and Grafana for Real-Time Analytics

When do you use a time-series database?

  • When your application needs data that accumulates quickly and your other databases aren’t designed to handle that scale.
  • For financial or industrial applications.
  • When your application needs to perform real-time analysis of billions of records.
  • When your application needs to perform online queries at millisecond timescales, and support CPU-efficient ad-hoc queries.

Challenges with the existing traditional databases

What is RedisTimeSeries?

Get Access to 80+ Redis Sample Apps ~ https://launchpad.redis.com

Notables features of RedisTimeseries includes:

  • High volume inserts, low latency reads
  • Query by start time and end-time
  • Aggregated queries (Min, Max, Avg, Sum, Range, Count, First, Last, STD.P, STD.S, Var.P, Var.S) for any time bucket
  • Configurable maximum retention period
  • Downsampling/Compaction — automatically updated aggregate time series
  • Secondary index — each time series has labels (field value pairs) which will allows to query by labels
