We're rolling back the Dockerfile changes introduced in 2.6.0. If you made changes to your docker deployment in 2.6.0, you will need to roll them back. This release also adds experimental support for disk size based retention. To accommodate that we are deprecating the flag `storage.tsdb.retention` in favour of `storage.tsdb.retention.time` . We print a warning if the flag is in use, but it will function without breaking until Prometheus 3.0.

2017-05-24 23:57:01 -07:00
## 0.16.0 / 2015-10-09
2015-09-11 08:29:25 -07:00
BREAKING CHANGES:
* 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`
2015-10-08 12:12:21 -07:00
to reflect support for DNS record types other than `SRV` .
2015-09-11 08:29:25 -07:00
* 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
2015-10-08 12:12:21 -07:00
the specified regular expression are no longer included in the replacement
output.
2015-09-11 08:29:25 -07:00
* Queries no longer interpolate between two data points. Instead, the resulting
value will always be the latest value before the evaluation query timestamp.
* 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
2015-10-08 12:12:21 -07:00
(Alertmanager, remote storages, federation). They have thus also been renamed
from `global.labels` to `global.external_labels` .
2015-09-11 08:29:25 -07:00
* The names and units of metrics related to remote storage sample appends have
been changed.
* 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.
2015-10-08 12:12:21 -07:00
* Escape sequences in double- and single-quoted string literals in rules or query
expressions are now interpreted like escape sequences in Go string literals
(https://golang.org/ref/spec#String_literals).
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.
* 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` .
2015-09-11 08:29:25 -07:00
All changes:
2015-10-08 12:12:21 -07:00

replacement.
* [CHANGE] Change default full refresh interval for the file-based service
discovery from 30 seconds to 5 minutes.

## 0.15.0 / 2015-07-21
2015-07-16 07:23:43 -07:00
BREAKING CHANGES:
2015-07-27 08:11:35 -07:00
* Relative paths for rule files are now evaluated relative to the config file.
* External reachability flags (`-web.*`) consolidated.
* The default storage directory has been changed from `/tmp/metrics`
2015-07-21 09:49:36 -07:00
to `data` in the local directory.
2015-07-27 08:11:35 -07:00
* The `rule_checker` tool has been replaced by `promtool` with
2015-07-21 09:49:36 -07:00
different flags and more functionality.
2015-07-27 08:11:35 -07:00
* Empty labels are now removed upon ingestion into the
2015-07-21 09:49:36 -07:00
storage. Matching empty labels is now equivalent to matching unset
labels (`mymetric{label=""}` now matches series that don't have
`label` set at all).
2015-07-27 08:11:35 -07:00
* The special `__meta_consul_tags` label in Consul service discovery
2015-07-21 09:49:36 -07:00
now starts and ends with tag separators to enable easier regex
matching.
2015-07-27 08:11:35 -07:00
* The default scrape interval has been changed back from 1 minute to
2015-07-21 09:49:36 -07:00
10 seconds.

2015-03-04 04:50:58 -08:00
* [CHANGE] Use client_golang v0.3.1. THIS CHANGES FINGERPRINTING AND INVALIDATES

later versions. There is a version guard in place that will prevent you to
run Prometheus with the stored data of an older Prometheus.

intensive.

(rather than /tmp/metrics).

2017-05-24 23:57:01 -07:00
## 0.11.1 / 2015-02-27

2015-02-27 02:47:43 -08:00
or commit 0851945, series would not be archived, chunk descriptors would
not be evicted, and stale head chunks would never be closed. This happened
due to accidental deletion of a line calling a (well tested :) function.
* [BUGFIX] Do not double count head chunks read from checkpoint on startup.
Also fix a related but less severe bug in counting chunk descriptors.
* [BUGFIX] Check last time in head chunk for head chunk timeout, not first.
* [CHANGE] Update vendoring due to vendoring changes in client_golang.
* [CLEANUP] Code cleanups.

2015-01-26 06:35:57 -08:00
* [CHANGE] More efficient JSON result format in query API. This requires
up-to-date versions of PromDash and prometheus_cli, too.
* [ENHANCEMENT] Excluded non-minified Bootstrap assets and the Bootstrap maps
from embedding into the binary. Those files are only used for debugging,
and then you can use -web.use-local-assets. By including fewer files, the
RAM usage during compilation is much more manageable.
