preq is powered by Common Reliability Enumerations (CREs) that are contributed by the community and Prequel's Reliability Research Team. Reliability intelligence helps teams see a broad range of problems earlier, so they can prioritize, pinpoint, and reduce the risk of outages.
Official binary distributions are available at latest release for Linux (amd64), macOS (amd64 and arm64), and Windows (amd64). All macOS binaries are signed and notarized. No configuration is necessary to start using preq.
preq is powered by a rules engine that performs distributed matching and correlation of sequences of events across logs, metrics, traces, and other data sources to detect reliability problems. CREs provides accurate and timely context for a human or SRE agent to take action on problems.
Below is simple rule that looks for a sequence of events in a single log source over a window of time along with a negative condition (an event that should not occur during the window).
