|
||
generic write interface with example adapter implementation for various
|
||
backends. Note that both the previous and the current remote write
|
||
implementations are **experimental**.
|
||
* [FEATURE] New flag `-storage.local.target-heap-size` to tell Prometheus about
|
||
the desired heap size. This deprecates the flags
|
||
`-storage.local.memory-chunks` and `-storage.local.max-chunks-to-persist`,
|
||
which are kept for backward compatibility.
|
||
* [FEATURE] Add `check-metrics` to `promtool` to lint metric names.
|
||
* [FEATURE] Add Joyent Triton discovery.
|
||
* [FEATURE] `X-Prometheus-Scrape-Timeout-Seconds` header in HTTP scrape
|

requests.

||
* [FEATURE] Marathon SD supports multiple ports.
|
||
* [FEATURE] Marathon SD supports bearer token for authentication.

|
||
before starting the final checkpoint.

|
||
the user, it is still honored as usual.
|
||
* [ENHANCEMENT] Close head chunks after being idle for the duration of the
|
||
configured staleness delta. This helps to persist and evict head chunk of

|
||
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.
|
||
* 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
|
||
(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.
|
||
* 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.
|
||
* 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`.
|
||
|
||

|
||
BREAKING CHANGES:
|
||
|
||
* 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`
|
||
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.

||
* The default scrape interval has been changed back from 1 minute to
|
||
10 seconds.

## 0.12.0 / 2015-03-04
|
||
* [CHANGE] Use client_golang v0.3.1. THIS CHANGES FINGERPRINTING AND INVALIDATES
|
||
ALL PERSISTED FINGERPRINTS. You have to wipe your storage to use this or
|
||
later versions. There is a version guard in place that will prevent you to
|
||
run Prometheus with the stored data of an older Prometheus.
|
||
* [BUGFIX] The change above fixes a weakness in the fingerprinting algorithm.
|
||
* [ENHANCEMENT] The change above makes fingerprinting faster and less allocation
|
||
intensive.

|
||
* [ENHANCEMENT] Scientific notation and special float values (Inf, NaN) now
|
||
supported by the expression language.

(rather than /tmp/metrics).

* [CHANGE] Makefile uses Go 1.4.2.
|
||
|
||
## 0.11.1 / 2015-02-27
|

|
||
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.
|
||
* [ENHANCEMENT] Limit the number of 'dirty' series counted during checkpointing.
|
||
|
||

||
* [FEATURE] Introduce new metric type Histogram with server-side aggregation.

||
* [FEATURE] Add offset operator.
|
||

|
||
proof-of-concept for federation via console templates.

||
* [BUGFIX] Fix Go download path for various architectures.
|
||
* [BUGFIX] Fixed the link of the Travis build status image.
|

|
||
|
||
## 0.10.0 / 2015-01-26
|
||
* [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.
|
||
* [ENHANCEMENT] Help link points to http://prometheus.github.io now.
|
||
* [FEATURE] Consoles for haproxy and cloudwatch.
|
||
* [BUGFIX] Several fixes to graphs in consoles.

|
||
* [CHANGE] Reworked command line flags, now more consistent and taking into

account needs of the new storage backend (see below).

|
||
* [CHANGE] Changed partitioning of summary metrics exported by Prometheus.
|
||
* [CHANGE] Got rid of Gerrit as a review tool.
|
||
* [CHANGE] 'Tabular' view now the default (rather than 'Graph') to avoid
|
||
running very expensive queries accidentally.
|
||
* [CHANGE] On-disk format for stored samples changed. For upgrading, you have
|
||
to nuke your old files completely. See "Complete rewrite of the storage
|
||
* [CHANGE] Removed 2nd argument from `delta`.

|
||
* Better query performance.
|

|
||
* Better memory management.
|
||
* Scales up to millions of time series and thousands of samples ingested
|
||
per second.
|
||
* Purging of obsolete samples much cleaner now, up to completely
|
||
"forgetting" obsolete time series.
|
||
* Proper instrumentation to diagnose the storage layer with... well...
|
||
Prometheus.
|
||
* Pure Go implementation, no need for cgo and shared C libraries anymore.

|
||
* [CLEANUP] Removed all legitimate 'go vet' and 'golint' warnings.
|
||
* [CLEANUP] Removed dead code.
|
||
|
||
