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.

  • If corruption is detected in an NNTBS shard, offline it instead of exiting with a fatal error.
    • Operators should be on the lookout for errorlog messages matching one of these patterns:
      Error committing txn: <return code> (error description)
      Error putting to lmdb cursor: <return code> (error description)
      If these logs appear, contact Circonus Support for help in remediating the issue.
  • Fix race condition in single-shard NNTBS reconstitute.
  • Fix crashes when trying to use graphite find on a node that is not participating in any topology.
  • Fix memory leaks when fetching graphite data.
  • Enable LMDB metadata sync for NNTBS shards.
  • Allow NNTBS shards to close properly on shutdown.
  • Fix memory leaks in the find path
  • Switch /rollup//<metric_name> endpoint to accept type=<derivative|derivative_stddev|derivative2|derivative2_stddev>
  • The utility snowth_lmdb_tool now supports a new "dump" sieve that can dump an entire NNTBS shard as text with human-readable surrogate id and timestamp fields.
  • Add Swagger documentation to be served directly out of IRONdb on /api/index.html.
  • Performance improvements to the reconstitute process - startup is now considerably faster.
  • Clean up internal status files when a reconstitute completes.
  • Node IDs in the Topology UI tab are now clickable, and lead to that node's UI.

Pre-upgrade Notice

The 2021-03-22 release changed the way CAQL metrics are labeled. Previously, if the label function was not used, resulting metrics would be named output[N]. As of the 2021-03-22 release, CAQL metrics are labeled based on the computation that led to the particular output.

This can cause the names of existing metrics to change, if no explicit label was given in the CAQL expression. To avoid this, run the following script on your "hub" node prior to updating if you are on a release earlier than 2021-03-22:

/www/bin/inside/label_caql_metrics.pl

This will locate active CAQL checks across all accounts that do not have explicit labels, and configure them to preserve the existing output[N] names. It is idempotent, so it is safe to run it multiple times if necessary.

caql_broker​

Version: 0.1.1616788161 (e02b97a)

Pre-upgrade Notice

The 2021-03-22 release changed the way CAQL metrics are labeled. Previously, if the label function was not used, resulting metrics would be named output[N]. As of the 2021-03-22 release, CAQL metrics are labeled based on the computation that led to the particular output.

This can cause the names of existing metrics to change, if no explicit label was given in the CAQL expression. To avoid this, run the following script on your "hub" node prior to updating if you are on a release earlier than 2021-03-22:

/www/bin/inside/label_caql_metrics.pl

This will locate active CAQL checks across all accounts that do not have explicit labels, and configure them to preserve the existing output[N] names. It is idempotent, so it is safe to run it multiple times if necessary.

  • No user-facing changes.

Version: 0.1.1617130292 (8d2b0ad)

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.

  • Fix possible deadlock on histogram fetch errors.
  • Add site-local extensions config file, /opt/circonus/etc/irondb-extensions-site.conf.
  • Make rollup and delete timing behavior more accurate, especially after crash or restart.
  • Replication Latency UI tab bugfix: now each node's latency is still calculated even if its sub-list isn't expanded (regression in 2021-03-22).
  • Fix potential crash when fetching metrics with very large names.
  • Fix potential deadlock in raw database rollups.
  • Update artmap file version from 1 to 2. Metric artmap files (cached tag-search indexes) will regenerate upon updating to this version, increasing search accuracy. This will cause the first service restart after upgrading to this version to be slower than normal. Take care during update not to have too many nodes restart at the same time.

fault_detection​

Version: 0.1.1616595856 (2948129)

  • Several fixes to make the /maintenance endpoint match documented behavior:
    • Fix parsing of shorthand string notation for maintenance severities.
    • Allow JSON arrays of ints to be used for maintenance severities.
    • Use a default value of [1,2,3,4,5] for maintenance severities.

  • Corrects a bug that could cause server panics if no memcache servers were assigned in the configuration.
  • Fixes an error that would allow certain values to break db queries with the order parameter on API search endpoints.
  • Corrects an error that occurs when metric search operation contain multiple terms containing only tag categories and not tag values.
  • Corrects how the db.Stats() wait_duration metric data is reported.
  • Corrects an error with metric search query parsing of search terms containing a tag category but not a tag value.
  • Allows the parse_only query parameter to work using the regular /metric endpoint.
  • Contains goapi implementation of the graph service.
  • Query parser errors will now return a 400 status code instead of an incorrect 500 status code.

Hooper​

Version: 0.1.1609887173 (4921f87)

  • (Breaking change) Replace the obsolete nad host agent with the current version of circonus-agent on all systems managed by Hooper. The format of metrics emitted by circonus-agent has changed, and now uses Stream Tags. Any existing checks/rules against nad on these hosts may need to be adjusted or replaced.
  • Fix bug in config-check with the ca role primary attribute.
  • stratcon: Enable tuning of timeouts for ingestion into IRONdb. This includes both TCP connection timeouts (connecttimeout) and overall transaction timeout (timeout). Values are in milliseconds. Deprecate the previous irondb_put_concurrency attribute in favor of a new irondb_tuning object, which can contain any of three keys:
    "irondb_tuning": {
      "timeout": 8000,
      "connecttimeout": 1000,
      "put_concurrency": 50
    }
    See site.json stratcon attributes for more details. Reducing IRONdb timeouts may improve ingestion throughput by allowing stratcon to move on more quickly from poorly-performing IRONdb nodes. However, setting timeouts too low could negatively impact ingestion as well.

libmtev​

Related roles: broker, caql_broker, data_storage, fault_detection, stratcon, web_stream

Version: 1.12.14

  • Fix missing top of crash stacktrace when libunwind is being used.
  • Set log message 'SSL layer X not understood' to debug-only if SSL version X is being explicitly disabled. This reduces logging noise with OpenSSL 1.1.x and later.
  • Fix segment_size and precommit config processing for jlog logs. Previously, application requests to set these parameters could sometimes be silently ignored.

notification​

Version: 0.1.1609956725 (b151580)

  • Bugfix: Correct handling of maintenance windows, expiration, incoming updates.

Reconnoiter​

Related roles: broker, caql_broker, data_storage, fault_detection, stratcon, web_stream

Version: 0.1.1608135246 (4b1e25d)

  • (broker) Reopen log files with dropped privileges. This addresses a corner case at startup where, if there is a JLog precommit buffer and the last available segment is full, a newly created segment will be owned by the wrong user.
  • (broker) Improved locking around filterset manipulation (crash fix).
  • (stratcon) Crash fix in the ingestion pipeline.
  • (stratcon) Fix crash when removing a broker that has data submissions in flight.

Web UI/API​

Version: 0.1.1610123864 (30c290c)

  • Bugfix: send maintenance window changes to the Notification service.
  • Bugfix: correct the Apache proxy forwarding rules to accommodate GoAPI proxy requests to Lua CAQL extensions.
  • Bugfix: when searching on the Alert History page, it would remove any date range filter you had previously selected.
  • Bugfix: support for streamtags and non-alphanumeric characters in metric names for SNMP and other checks. Also requires broker update to support this case.
