  • v0.15.1 Changes

    July 27, 2015
    • 🛠 [BUGFIX] Fix vector matching behavior when there is a mix of equality and non-equality matchers in a vector selector and one matcher matches no series.
    • [ENHANCEMENT] Allow overriding GOARCH and GOOS in Makefile.INCLUDE.
    • ⚡️ [ENHANCEMENT] Update vendored dependencies.
  • v0.15.0 Changes

    July 21, 2015

    💥 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    • The rule_checker tool has been replaced by promtool with different flags and more functionality.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.

    • 🛠 [BUGFIX] Check last time in head chunk for head chunk timeout, not first.

    • [CLEANUP] Code cleanups.
    • [ENHANCEMENT] Limit the number of 'dirty' series counted during checkpointing.
