  • v0.16.0 Changes

    October 09, 2015


    • ๐Ÿš€ Release tarballs now contain the built binaries in a nested directory.
    • The hash_mod relabeling action now uses MD5 hashes instead of FNV hashes to achieve a better distribution.
    • The DNS-SD meta label __meta_dns_srv_name was renamed to __meta_dns_name to reflect support for DNS record types other than SRV.
    • 0๏ธโƒฃ The default full refresh interval for the file-based service discovery has been increased from 30 seconds to 5 minutes.
    • In relabeling, parts of a source label that weren't matched by the specified regular expression are no longer included in the replacement output.

    • ๐Ÿ”ง Regular expressions supplied via the configuration are now anchored to match full strings instead of substrings.
    • Global labels are not appended upon storing time series anymore. Instead, they are only appended when communicating with external systems (Alertmanager, remote storages, federation). They have thus also been renamed from global.labels to global.external_labels.
    • The names and units of metrics related to remote storage sample appends have been changed.
    • โšก๏ธ The experimental support for writing to InfluxDB has been updated to work with InfluxDB 0.9.x. 0.8.x versions of InfluxDB are not supported anymore.

    ๐Ÿ—„ Future breaking changes / deprecated features:

    • The delta() function had an undocumented optional second boolean argument to make it behave like increase(). This second argument will be removed in the future. Migrate any occurrences of delta(x, 1) to use increase(x) instead.
    • ๐Ÿ‘Œ Support for filter operators between two scalar values (like 2 > 1) will be removed in the future. These will require a bool modifier on the operator, e.g. 2 > bool 1.

    All changes:

    • [CHANGE] Renamed global.labels to global.external_labels.
    • [CHANGE] Vendoring is now done via govendor instead of godep.
    • ๐Ÿ’ป [CHANGE] Change web UI root page to show the graphing interface instead of the server status page.
