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.
- [CLEANUP] Removed a file size check that did not check anything.
0.9.0 / 2015-01-23
- [CHANGE] Reworked command line flags, now more consistent and taking into account needs of the new storage backend (see below).
- [CHANGE] Metric names are dropped after certain transformations.
- [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
. - [FEATURE] Added a
deriv
function. - [FEATURE] Console templates.
- [FEATURE] Added
absent
function. - [FEATURE] Allow omitting the metric name in queries.
- [BUGFIX] Removed all known race conditions.
- [BUGFIX] Metric mutations now handled correctly in all cases.
- [ENHANCEMENT] Proper double-start protection.
- [ENHANCEMENT] Complete rewrite of the storage layer. Benefits include:
- Better query performance.
- More samples in less RAM.
- 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.
- Better concurrency.
- [ENHANCEMENT] Copy-on-write semantics in the AST layer.
- [ENHANCEMENT] Switched from Go 1.3 to Go 1.4.
- [ENHANCEMENT] Vendored external dependencies with godeps.
- [ENHANCEMENT] Numerous Web UI improvements, moved to Bootstrap3 and Rickshaw 1.5.1.
- [ENHANCEMENT] Improved Docker integration.
- [ENHANCEMENT] Simplified the Makefile contraption.
- [CLEANUP] Put meta-data files into proper shape (LICENSE, README.md etc.)
- [CLEANUP] Removed all legitimate 'go vet' and 'golint' warnings.
- [CLEANUP] Removed dead code.
0.8.0 / 2014-09-04
- [ENHANCEMENT] Stagger scrapes to spread out load.
- [BUGFIX] Correctly quote HTTP Accept header.
0.7.0 / 2014-08-06
- [FEATURE] Added new functions: abs(), topk(), bottomk(), drop_common_labels().
- [FEATURE] Let console templates get graph links from expressions.
- [FEATURE] Allow console templates to dynamically include other templates.
- [FEATURE] Template consoles now have access to their URL.
- [BUGFIX] Fixed time() function to return evaluation time, not wallclock time.
- [BUGFIX] Fixed HTTP connection leak when targets returned a non-200 status.
- [BUGFIX] Fixed link to console templates in UI.
- [PERFORMANCE] Removed extra memory copies while scraping targets.
- [ENHANCEMENT] Switched from Go 1.2.1 to Go 1.3.
- [ENHANCEMENT] Made metrics exported by Prometheus itself more consistent.
- [ENHANCEMENT] Removed incremental backoffs for unhealthy targets.
- [ENHANCEMENT] Dockerfile also builds Prometheus support tools now.
0.6.0 / 2014-06-30
- [FEATURE] Added console and alert templates support, along with various template functions.
- [PERFORMANCE] Much faster and more memory-efficient flushing to disk.
- [ENHANCEMENT] Query results are now only logged when debugging.
- [ENHANCEMENT] Upgraded to new Prometheus client library for exposing metrics.
- [BUGFIX] Samples are now kept in memory until fully flushed to disk.
- [BUGFIX] Non-200 target scrapes are now treated as an error.
- [BUGFIX] Added installation step for missing dependency to Dockerfile.
- [BUGFIX] Removed broken and unused "User Dashboard" link.
0.5.0 / 2014-05-28
- [BUGFIX] Fixed next retrieval time display on status page.
- [BUGFIX] Updated some variable references in tools subdir.
- [FEATURE] Added support for scraping metrics via the new text format.
- [PERFORMANCE] Improved label matcher performance.
- [PERFORMANCE] Removed JSON indentation in query API, leading to smaller response sizes.
- [ENHANCEMENT] Added internal check to verify temporal order of streams.
- [ENHANCEMENT] Some internal refactorings.
0.4.0 / 2014-04-17
- [FEATURE] Vectors and scalars may now be reversed in binary operations (
<scalar> <binop> <vector>
). - [FEATURE] It's possible to shutdown Prometheus via a
/-/quit
web endpoint now. - [BUGFIX] Fix for a deadlock race condition in the memory storage.
- [BUGFIX] Mac OS X build fixed.
- [BUGFIX] Built from Go 1.2.1, which has internal fixes to race conditions in garbage collection handling.
- [ENHANCEMENT] Internal storage interface refactoring that allows building e.g. the
rule_checker
tool without LevelDB dynamic library dependencies. - [ENHANCEMENT] Cleanups around shutdown handling.
- [PERFORMANCE] Preparations for better memory reuse during marshalling / unmarshalling.
