## 1.6.0 / 2017-04-14
|
|
|
|
|
|
|
|
|
|
* [CHANGE] Replaced the remote write implementations for various backends by a
|
|
|
|
|
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] Remote read interface, including example for InfluxDB. **Experimental.**
|
|
|
|
|
* [FEATURE] Enable Consul SD to connect via TLS.
|
|
|
|
|
* [FEATURE] Marathon SD supports multiple ports.
|
|
|
|
|
* [FEATURE] Marathon SD supports bearer token for authentication.
|
|
|
|
|
* [FEATURE] Custom timeout for queries.
|
|
|
|
|
* [FEATURE] Expose `buildQueryUrl` in `graph.js`.
|
|
|
|
|
* [FEATURE] Add `rickshawGraph` property to the graph object in console
|
|
|
|
|
templates.
|
|
|
|
|
* [FEATURE] New metrics exported by Prometheus itself:
|
|
|
|
|
* Summary `prometheus_engine_query_duration_seconds`
|
|
|
|
|
* Counter `prometheus_evaluator_iterations_missed_total`
|
|
|
|
|
* Counter `prometheus_evaluator_iterations_total`
|
|
|
|
|
* Gauge `prometheus_local_storage_open_head_chunks`
|
|
|
|
|
* Gauge `prometheus_local_storage_target_heap_size`
|
|
|
|
|
* [ENHANCEMENT] Reduce shut-down time by interrupting an ongoing checkpoint
|
|
|
|
|
before starting the final checkpoint.
|
|
|
|
|
* [ENHANCEMENT] Auto-tweak times between checkpoints to limit time spent in
|
|
|
|
|
checkpointing to 50%.
|
|
|
|
|
* [ENHANCEMENT] Improved crash recovery deals better with certain index
|
|
|
|
|
corruptions.
|
|
|
|
|
* [ENHANCEMENT] Graphing deals better with constant time series.
|
|
|
|
|
* [ENHANCEMENT] Retry remote writes on recoverable errors.
|
|
|
|
|
* [ENHANCEMENT] Evict unused chunk descriptors during crash recovery to limit
|
|
|
|
|
memory usage.
|
|
|
|
|
* [ENHANCEMENT] Smoother disk usage during series maintenance.
|
|
|
|
|
* [ENHANCEMENT] Targets on targets page sorted by instance within a job.
|
|
|
|
|
* [ENHANCEMENT] Sort labels in federation.
|
|
|
|
|
* [ENHANCEMENT] Set `GOGC=40` by default, which results in much better memory
|
|
|
|
|
utilization at the price of slightly higher CPU usage. If `GOGC` is set by
|
|
|
|
|
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
|
|
|
|
|
stale series more quickly.
|
|
|
|
|
* [ENHANCEMENT] Stricter checking of relabel config.
|
|
|
|
|
* [ENHANCEMENT] Cache busters for static web content.
|
|
|
|
|
* [ENHANCEMENT] Send Prometheus-specific user-agent header during scrapes.
|
|
|
|
|
* [ENHANCEMENT] Improved performance of series retention cut-off.
|
|
|
|
|
* [ENHANCEMENT] Mitigate impact of non-atomic sample ingestion on
|
|
|
|
|
`histogram_quantile` by enforcing buckets to be monotonic.
|
|
|
|
|
* [ENHANCEMENT] Released binaries built with Go 1.8.1.
|
|
|
|
|
* [BUGFIX] Send `instance=""` with federation if `instance` not set.
|
|
|
|
|
* [BUGFIX] Update to new `client_golang` to get rid of unwanted quantile
|
|
|
|
|
metrics in summaries.
|
|
|
|
|
* [BUGFIX] Introduce several additional guards against data corruption.
|
|
|
|
|
* [BUGFIX] Mark storage dirty and increment
|
|
|
|
|
`prometheus_local_storage_persist_errors_total` on all relevant errors.
|
|
|
|
|
* [BUGFIX] Propagate storage errors as 500 in the HTTP API.
|
|
|
|
|
* [BUGFIX] Fix int64 overflow in timestamps in the HTTP API.
|
|
|
|
|
* [BUGFIX] Fix deadlock in Zookeeper SD.
|
|
|
|
|
* [BUGFIX] Fix fuzzy search problems in the web-UI auto-completion.
