Prometheus v0.15.0 Release Notes

Release Date: 2015-07-21 // almost 9 years ago

  • 💥 BREAKING CHANGES:

    • Relative paths for rule files are now evaluated relative to the config file.
    • 🌐 External reachability flags (-web.*) consolidated.
    • 0️⃣ The default storage directory has been changed from /tmp/metrics to data in the local directory.
    • The rule_checker tool has been replaced by promtool with different flags and more functionality.
    • 🚚 Empty labels are now removed upon ingestion into the storage. Matching empty labels is now equivalent to matching unset labels (mymetric{label=""} now matches series that don't have label set at all).
    • The special __meta_consul_tags label in Consul service discovery now starts and ends with tag separators to enable easier regex matching.
    • 0️⃣ The default scrape interval has been changed back from 1 minute to 10 seconds.
