  • /fetch numeric transforms now support a fill=<X|forward kwarg. (CIRC-8850)
  • CAQL optimizations for numeric find() | fill() and find | fill:foward(). (CIRC-8850)
  • Introduce a /find query classification and isolation system. (CIRC-8849)
    • Consolidate /find (related) endpoints to use three new classes of jobq called find_{local,remote}, find_fast_{local,remote}, and find_slow_{local,remote}.
    • Add a performance profiling system to track and classify /find to place them automatically into each of these three new classes.
  • Add jobq mode (LIFO/FIFO) to snowth console web UI.
  • Expand /find calls to pull from all nodes if the user specifies that they want the latest datapoints to be included. (CIRC-8832)

Version: 0.13.10

GoAPI​

Related roles: api

Version: 0.12.18

  • Correct a bug resulting in CAQL query cache data not being updated correctly when context timeout errors occurred. (CIRC-8743)
  • Fix a bug resulting in errors during log file rotation causing the log to revert to outputting to stderr. (CIRC-8743)
  • Bring v2 search syntax into parity with Perl search syntax. Search terms will be combined using OR only if they contain the same term. Otherwise, all search terms are combined using AND. (CIRC-8654)
    • For example, the query (active:1)(active:0)(name:test) will result in a search where (active = 1 OR active = 0) AND name = test.
  • When the /alert endpoint finds an alert for a rule set group it will now correctly return a /rule_set_group/{id} CID in the rule_set field, and no longer return an incorrect /rule_set/{id} CID. (CIRC-8814)
  • Add a search term called related to the /alert endpoint. When provided with an alert CID or ID, it will return all alerts related to the provided CID (i.e. members of a rule set group alert.) (CIRC-8814)
  • Update the active search term for the /alert endpoint, so that a search of (active:*) will return both active and inactive alerts. (CIRC-8814)
  • Fix a bug that was causing context errors during IRONdb operations to sometimes get incorrectly wrapped in a 500 Database error, resulting in incorrect reporting of error statistics. (CIRC-8830)
  • Update gosnowth library to v1.11.0. Uses the type definitions for DF4 from the gosnowth library exclusively, and eliminates redundant DF4 types in GoAPI. This adds the missing head.error and head.warning fields to results that return data in DF4 format when they are available. And, this fixes several small bugs in the DF4 Go implementation. (CIRC-8800)

  • Improve default labels for CAQL delay(...)
  • Use less memory from tag queries. (CIRC-8593)
  • Use less memory for tag index compaction. (CIRC-8578)

Function Removal Notice

Metric Search v2 and Metric Clusters have been deprecated for some time. We plan to remove these deprecated functions soon for the SaaS site, and in the subsequent Inside release. This will affect CAQL checks as well as CAQL Datapoints on graphs. The UI will now show users a warning when one of the deprecated functions is used. Circonus offers a more powerful tag-search feature, exposed as find() in CAQL.

  • Add support for find hinting. This allows adding hints such as and(hint(__check_uuid:<a uuid>,index:none)) that will make the search evaluate against an existing set rather than using the full metric index. (CIRC-7654)
    • Note: this is an experimental feature. It is not yet used by the product, but provides a basis for improved query optimizations in the future.
  • Fix egress_function field updates in surrogate entries. (CIRC-7873)
  • Make histogram:sum() not normalize by default, period= behavior is unchanged. This is a change in the default. (CIRC-7869)
  • Make find:sum() not normalize by default and add a period= kwarg to support normalization. (CIRC-7869)
  • Add op:div2 to CAQL strictly requiring two arguments. Make / use op:div2. (CIRC-7864)
  • Fix /fetch reductions of sum and count to return a stream of zeroes when zero metrics are requested. (CIRC-7863)
  • Change logic for finding best node to be smarter and find valid data more frequently. (CIRC-7848)
  • Add math:ceil and math:round to CAQL. (CIRC-7637)
  • Allow operator to set jlog precommit buffer size on metadata feeds via //metadata/@feed_precommit_size. (CIRC-7852)
  • Add histogram merge pipeline reordering when trailing pipeline functions are commutative. (CIRC-7846)
  • Add CAQL /fetch optimization for histogram:count(), histogram:count_above(), histogram:count_below(), histogram:rate_above(), and histogram:rate_below(). (CIRC-7844)
  • Unoptimized histogram:rate() math fixed to match (correct) optimized version. (CIRC-7845)
  • Add filter:sum:* and filter:not:sum:* functions for graphite translation assistance. (CIRC-7842)

This will affect CAQL checks as well as CAQL Datapoints on graphs. The UI will now show users a warning when one of the deprecated functions is used. Circonus offers a more powerful tag-search feature, exposed as find() in CAQL.

  • Graphite find endpoint will no longer return a 500 on a bad request, favoring the more accurate 400 error.
  • Fix crash when attempting to fetch histogram shard data from the /histogram_raw endpoint when histogram shards are not enabled.
  • Fix crash when enabling the monitor module and using the legacy histogram database.
  • Gossip messages modified to be larger and fewer in number.
  • DELETE on /full/tags now accepts X-Snowth-Advisory-Limit properly to limit the number of deletes that will occur in one operation.
    • There is also a config-based maximum that this value may be, and beyond which the limit set by X-Snowth-Advisory-Limit will not be respected. The default is 10,000 metrics per batch. To change the advisory limit maximum, add the following line of configuration, within the <rest> stanza:
      <rest>
        ...
        <delete max_advisory_limit="20000"/>
      </rest>
    • Additionally, this endpoint now returns the header X-Snowth-Incomplete-Results: "true" if the requested delete operation requires more deletes than allowed by X-Snowth-Advisory-Limit or the server-configured maximum. This helps ensure that very large deletes will not consume memory ad infinitum. NOTE: This is a change in behavior. If utilizing the full delete API in scripting, use a loop to maintain the previous behavior, e.g.
      do {
         response = call-delete-api()
      } while( response->header->'X-Snowth-Incomplete-Results: "true"' )
  • Add explicit histogram:random: functions for each supported CDF.
  • Fix bug where jlog subscribers could hang around for too long, causing journal data that should have been removed to remain on disk until the next time the node restarts.

  • Change user-facing CAQL errors to 400 (from 520) HTTP codes.
  • Implement each:coalesce(X) in CAQL.
  • NNTBS shard states are now being reported to stats.json.
  • vector:pack() now takes a meta option that passed tag/name stream metadata through. The default (1) is to pass through metadata. This changes the default naming of unpacked vectors.
  • vector:pack() now takes a sloppy option that allows colliding streams by vector index. The default (0) will throw a run-time error when two streams map to the same vector index.
  • Finding an unconfigured shard on disk during boot will no longer result in a FATAL exit.
  • CAQL histogram:sum() now supports a period kwarg defaulting to 1M.
  • /fetch sums now normalize to 1s ranges and support override with period kwarg.
  • Support period=X transform and reduce arguments for histogram:rate functions.
  • Add rate_below and rate_above transform operations for /fetch.
  • Add each_rate_below and each_rate_above reduce operations for /fetch.
  • Update reporting of syntax errors in find tag queries to offer more in-depth information to users.
  • Fix CAQL histogram:rate(period=X) where X is not 1s when optimization is on.
  • Support smart quotes in CAQL for strings.
  • CAQL is now strict for duration-typed arguments.
  • Allow CAQL non-aggregate-safe CAQL functions to work on sub-minute periods.
  • Fix table header on #internals tab in web console.
  • Prevent NNTBS timeshard manager from accidentally opening a shard in maintenance.
  • Completely deprecate all system configuration via the <pools> stanza. New configuration will need to be done via the <eventer> stanza. Any existing <pools> values will be ignored and a warning message will print to the error log.
  • Improve rollup efficiency by no longer rolling up raw numeric shards that fall entirely outside of all NNTBS retention windows. Instead, mark them as completed so they will be removed.
