OpenTSDB 2.3.1

@manolama manolama released this May 22, 2018 · 1 commit to master since this release

  • Version 2.3.1 (2018-04-21)

Noteworthy Changes:

  • When setting up aggregators, advance to the first data point equal to or greater
    than the query start timestamp. This helps with calendar downsampling intervals.
  • Add support to the Nagios check script for downsampling fill policies.

Bug Fixes:

  • Fix expression calculation by avoiding double execution and checking both
    output types for boolean values.
  • Fixing missing tools scripts in builds.
  • Default HBase 1.2.5 in the OSX install script
  • Upgrade AsyncBigtable to 0.3.1
  • Log query stats when a channel is closed unexpectedly.
  • Add the Java 8 path in the debian init script and remove Java 6.
  • Pass the column family name to the get requests in the compaction scheduler.
  • Fix a comparison issue in the UI on group by tags.
  • Filter annotation queries by the starting timestamp, excluding those in a row that
    began before the query start time.
  • Tiny stap at purging backticks from Gnuplot scripts.
  • Remove the final annotation from the meta classes so they can be extended.
  • Fix the javacc maven plugin version.
  • Fix the literal or filter to allow single character filters.
  • Fix query start stats logging to use the ms instead of nano time.
  • Move Jackson and Netty to newer versions for security reasons.
  • Upgrade to AsyncHBase 1.8.2 for compatibility with HBase 1.3 and 2.0
  • Fix the Highest Current calculation to handle empty time series.
  • Change the cache hits counters to longs.

OpenTSDB 2.4.0 RC2

@manolama manolama released this Oct 9, 2017 · 20 commits to next since this release

  • Version 2.4.0 RC2 (2017-10-08)

Noteworthy Changes:

  • Modify the RPC handler plugin system so that it parses only the first part of
    the URI instead of the entire path. Now plugins can implement sub-paths.
  • Return the HTML 5 doctype for built-in UI pages
  • Add an optional byte and/or data point limit to the amount of data fetched
    from storage. This allows admins to prevent OOMing TSDs due to massive queries.
  • Allow a start time via config when enabling the date tiered compaction in HBase
  • Provide the option of using an LRU for caching UIDs to avoid OOMing writers and
    readers with too many strings
  • Optionally avoid writing to the forward or reverse UID maps when a specific TSD
    operational mode is enabled to avoid wasting memory on maps that will never be
    used.

Bug Fixes:

  • Roll back UTF8 issue with UIDs in RC1 wherein the stored bytes weren't converting
    properly and vice-versa. We'll have to work on full UTF8 support in 3.x
  • Fix a build issue for Javacc
  • Add Kryo as a dependency to the fat jar
  • Javadoc fixes
  • Fix an issue with calendar aligned downsampling by seeking to the start time of
    the query when the zone-aligned timestamp may be earlier than the query start time
  • Add the missing QueryLimitOverride to the makefile
  • Fix compatibility with Bigtable for 2.4
  • Enable standard read-only APIs when the TSD is in write only mode

Noteworthy Changes:

  • Release of 2.3.0.

OpenTSDB 2.2.2

@manolama manolama released this Dec 29, 2016 · 297 commits to master since this release

  • Version 2.2.2 (2016-12-29)

Bug Fixes:

  • Fix an issue with writing metadata where using custom tags could cause the compare-
    and-set to fail due to variable ordering in Java's heap. Now tags are sorted so the
    custom tag ordering will be consistent.
  • Fix millisecond queries that would miss data the top of the final hour if the end
    time was set to 1 second or less than the top of that final hour.
  • Fix a concurrent modification issue where salt scanners were not synchronized on the
    annotation map and could cause spinning threads.

OpenTSDB 2.2.1

@manolama manolama released this Oct 8, 2016 · 303 commits to master since this release

  • Version 2.2.1 (2016-10-08)

Noteworthy Changes

  • Generate an incrementing TSMeta request only if both enable_tsuid_incrementing and
    tsd.core.meta.enable_realtime_ts are enabled. Previously, increments would run
    regardless of whether or not the real time ts setting was enabled. If tsuid
    incrementing is disabled then a get and optional put is executed each time without
    modifying the meta counter field.
  • Improve metadata storage performance by removing an extra getFromStorage() call.
  • Add global Annotations to the gnuplot graphs (#773)
  • Allow creation of a TSMeta object without a TSUID (#778)

  • Fix some query stats calculations around averaging and estimating the number
    of data points (#784).
  • Clean out old .SWO files (#821)
  • Fix a live-lock situation when performing regular expression or wildcard queries (#823).
  • Change the static file path for the HTTP API to be relative (#857).
  • Fix an issue where the GUI could flicker when two or more tag filters were set (#708).

OpenTSDB 2.2.0

@manolama manolama released this Feb 15, 2016 · 342 commits to master since this release

  • 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

      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.

      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.

      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)

  • Fix an NPE thrown when accessing the /logs endpoint if the Cyclic appender is not
    enabled in the logback config.
