Histograms are a data structure for representing large quantities of samples (such as the latencies of all API requests). OpenHistogram is a vendor-neutral log-linear histogram technology for the compression and analysis of telemetry data. OpenHistogram efficiently stores an unlimited volume of high-frequency data for years using sophisticated data compression, enabling users to see a more complete and real-time picture of their underlying systems.
“We use Circonus’ histograms extensively to surface issues before users notice them. We also have alerting set up such that if we start to burn error budget in latency for a particular service too quickly, we alert the team. The histograms enable us to identify these issues and make adjustments right away.”
