Opentsdb Versions Save

• Version 2.2.0 (2016-02-14)
  • Add the option to randomly assign UIDs to metrics to improve distribution across HBase region servers.
  • Introduce salting of data to improve distribution of high cardinality regions across region servers.
  • Introduce query stats for tracking various timings related to TSD queries.
  • Add more stats endpoints including /threads, /jvm and /region_clients
  • Allow for deleting UID mappings via CLI or the API
  • Name the various threads for easier debugging, particularly for distinguishing between TSD and AsyncHBase threads.
  • Allow for pre-fetching all of the meta information for the tables to improve performance.
  • Update to the latest AsyncHBase with support for secure HBase clusters and RPC timeouts.
  • Allow for overriding metric and tag widths via the config file. (Be careful!)
  • URLs from the API are now relative instead of absolute, allowing for easier reverse proxy use.
  • Allow for percent deviation in the Nagios check
  • Let queries skip over unknown tag values that may not exist yet (via config)
  • Add various query filters such as case (in)sensitive pipes, wildcards and pipes over tag values. Filters do not work over metrics at this time.
  • Add support for writing data points using Appends in HBase as a way of writing compacted data without having to read and re-write at the top of each hour.
  • Introduce an option to emit NaNs or Nulls in the JSON output when downsampling and a bucket is missing values.
  • Introduce query time flags to show the original query along with some timing stats in the response.
  • Introduce a storage exception handler plugin that will allow users to spool or requeue data points that fail writes to HBase due to various issues.
  • Rework the HTTP pipeline to support plugins with RPC implementations.
  • Allow for some style options in the Gnuplot graphs.
  • Allow for timing out long running HTTP queries.
  • Text importer will now log and continue bad rows instead of failing.
  • New percentile and count aggregators.
  • Add the /api/annotations endpoint to fetch multiple annotations in one call.
  • Add a class to support improved bulk imports by batching requests in memory for a full hour before writing.
  • Allow overriding the metric and tag UID widths via config file instead of having to modify the source code.
  • Rework the QueryStats output to be a bit more useful and add timings from the various scanners and query components.
  • Modify the UI to allow for group by or aggregate per tag (use the new query feature)
  • Rework the UI skin with the new TSDB logo and color scheme.
  • Add the QueryLog config to logback.xml so users can optionally enable logging of all queries along with their stats.

• Version 2.1.4 (2016-02-14)

Bug Fixes:

• Fix the meta table where the UID/TSMeta APIs were not sorting tags properly prior to creating the row key, thus allowing for duplicates if the caller changed the order of tags.
• Fix a situation where meta sync could hang forever if a routine threw an exception.
• Fix an NPE thrown when accessing the /logs endpoint if the Cyclic appender is not enabled in the logback config.
• Remove an overly chatty log line in TSMeta on new time series creation.

Bug Fixes:

• Fix build issues where the static files were not copied into the proper location.

Bug Fixes:

• Fix build issues where the static files were not copied into the proper location.

• Version 2.2.0 RC2 (2015-11-09)

Noteworthy Changes:

• Fix random metric UID assignment in the CLI tool.
• Fix for meta data sync when salting is enabled.

Bug Fixes:

• Fix comments about the Zookeeper quorum setting in various config files.
• Fix quoting in the Makefile when installing.

Bug Fixes:

• Modify the .rpm build to allow dashes in the name.
• Allow the Nagios check script to handle 0 values properly in checks.
• Fix FSCK where floating point values were not processed correctly (#430)
• Fix missing information from the /appi/uid/tsmeta calls (#498)
• Fix more issues with the FSCK around deleting columns that were in the list (#436)
• Avoid OOM issues over Telnet when the sending client isn't reading errors off it's socket fast enough by blocking writes.

• Version 2.1.1 (2015-09-12)

Bug Fixes:

• Relax the pgrep regex to correctly find and kill the java process in the RPM init.d script.
• Improve query performance slightly when aggregating multiple series.
• Fix the /api/search/lookup API call to properly handle the limit parameter.
• Fix the /api/query/last endpoint to properly handle missing tsdb-meta tables.

• Version 2.1.0 (2015-05-06)

Bug Fixes:

• FSCK was not handling compacted and floating point duplicates properly. Now they are merged correctly.
• TSMeta data updates were not loading the latest data from storage on response
• The config class will now trim spaces from booleans and integers
• On shutdown, the idle state handler could prevent the TSD from shutting down gracefully. A new thread factory sets that thread as a daemon thread.
• TSMeta objects were not generated if multiple writes for the same data point arrived in succession due to buffering atomic increments. Increments are no longer buffered.
• Updated paths to the deprecated Google Code repo for dependencies.

• Version 2.1.0 RC1 (2015-04-04)

Noteworthy Changes:

• Handle idle connections in Netty by closing them after some period of inactivity

• Various RPM script and package fixes
• Properly handle deletions of the cache directory while running

• Report stats properly when the UID is greater than 3 bytes wide

• Log illegal put exceptions at the debug level
• Fix global annotation retrieval where some entries were missing
• Fix unit tests that were not properly mocking out clients or threads and causing JVM OOMs
• Fix accounting bugs in FSCK
• Sort aggregators in the UI
• Properly throw an exception if the user supplies an empty tag on storage or retreival
• Handle missing directories in the Config class
