SQLite Observer & Exporter for SQLite

Rust docs Crates.io

This provides a fairly simple SQLite powered backend for the metrics crate, useful for offline or desktop applications to gather metrics that can be easily queried afterwards.

Version 0.4 Notes

  • Now works with metrics 0.20.x
  • _register!() macros aren't required & don't do anything with this exporter currently
  • Unit/description now available via _describe!() macros metrics provides

Version 0.3 Notes

  • Now vacuums on setup which can incur a delay in being ready to record
  • Migration of database blows away 0.2 data unfortunately

Example

    let exporter = SqliteExporter::new(
        Duration::from_secs(30), // flush to sqlite on disk every 30s (or internal buffer limit)
        Some(Duration::from_secs(60 * 60 * 24 * 7)), // 60 sec * 60 min * 24 hours * 7 days
        "metrics.db",
    )
    .expect("Failed to create SqliteExporter");
    exporter
        .install()
        .expect("Failed to install SqliteExporter");

// use metrics macros etc.
metrics::gauge!("mykey", 1.0);
