  • Separate query-service functionality from http handler (#1312, @annanay25)

Breaking Changes

Migration Path:

  1. Run plugin/storage/cassandra/schema/migration/v001tov002part1.sh which will copy dependencies into a csv, update the dependency UDT, create a new dependencies_v2 table, and write dependencies from the csv into the dependencies_v2 table.
  2. Run the collector and query services with the cassandra flag cassandra.enable-dependencies-v2=true which will instruct jaeger to write and read to and from the new dependencies_v2 table.
  3. Update spark job to write to the new dependencies_v2 table. The feature will be done in #58.
  4. Run plugin/storage/cassandra/schema/migration/v001tov002part2.sh which will DELETE the old dependency table and the SASI index.

Users who wish to continue to use the v1 table don't have to do anything as the cassandra flag cassandra.enable-dependencies-v2 will default to false. Users may migrate on their own timeline however new features will be built solely on the dependencies_v2 table. In the future, we will remove support for v1 completely.

  • Remove ErrorBusy, it essentially duplicates SpansDropped (#1091, @cstyan)

1.9.0 (2019-01-21)

Backend Changes

Breaking Changes

Changed index prefix separator from : to - because Elasticsearch 7 does not allow : in index name. Jaeger query still reads from old indices containing - as a separator, therefore no configuration or migration changes are required.

  • Add CLI configurable es.max-num-spans while retrieving spans from ES (#1283, @annanay25)

The default value is set to 10000. Before no limit was applied.

  • Update to jaeger-lib 2 and latest sha for jaeger-client-go, to pick up refactored metric names (#1282, @objectiser)

Update to latest version of jaeger-lib, which includes a change to the naming of counters exported to prometheus, to follow the convention of using a _total suffix, e.g. jaeger_query_requests is now jaeger_query_requests_total.

Jaeger go client metrics, previously under the namespace jaeger_client_jaeger_ are now under jaeger_tracer_.

The following metrics:

jaeger_agent_tchannel_reporter_batch_size{format="jaeger"} 0
jaeger_agent_tchannel_reporter_batch_size{format="zipkin"} 0
jaeger_agent_tchannel_reporter_batches_failures{format="jaeger"} 0
jaeger_agent_tchannel_reporter_batches_failures{format="zipkin"} 0
jaeger_agent_tchannel_reporter_batches_submitted{format="jaeger"} 0
jaeger_agent_tchannel_reporter_batches_submitted{format="zipkin"} 0
jaeger_agent_tchannel_reporter_spans_failures{format="jaeger"} 0

jaeger_agent_collector_proxy{endpoint="baggage",result="ok"} 0
jaeger_agent_collector_proxy{endpoint="sampling",result="err"} 0
jaeger_agent_collector_proxy{endpoint="sampling",result="ok"} 0

have been renamed to:

jaeger_agent_reporter_batch_size{format="jaeger",protocol="tchannel"} 0
jaeger_agent_reporter_batch_size{format="zipkin",protocol="tchannel"} 0
jaeger_agent_reporter_batches_failures{format="jaeger",protocol="tchannel"} 0

Backend Changes

Breaking Changes

The following agent flags has been deprecated in order to support multiple reporters:

--collector.host-port
--discovery.conn-check-timeout
--discovery.min-peers

New flags:

--reporter.tchannel.host-port
--reporter.tchannel.discovery.conn-check-timeout
--reporter.tchannel.discovery.min-peers
  • Various changes around metrics produced by jaeger-query: Names scoped to the query component, generated for all span readers (not just ES), consolidate query metrics and include result tag (#1074, #1075 and #1096, @objectiser)

For example, sample of metrics produced for find_traces operation before:

jaeger_find_traces_attempts 1
jaeger_find_traces_errLatency_bucket{le="0.005"} 0
jaeger_find_traces_errors 0
jaeger_find_traces_okLatency_bucket{le="0.005"} 0
jaeger_find_traces_responses_bucket{le="0.005"} 1
jaeger_find_traces_successes 1

And now:

jaeger_query_latency_bucket{operation="find_traces",result="err",le="0.005"} 0
jaeger_query_latency_bucket{operation="find_traces",result="ok",le="0.005"} 2
jaeger_query_requests{operation="find_traces",result="err"} 0
jaeger_query_requests{operation="find_traces",result="ok"} 2
jaeger_query_responses_bucket{operation="find_traces",le="0.005"} 2

1.6.0 (2018-07-10)

Backend Changes

Breaking Changes

  • The storage implementations no longer write the parentSpanID field to storage (#856). If you are upgrading to this version, you must upgrade query service first!

  • Update Dockerfiles to reference executable via ENTRYPOINT (#815) by Zachary DiCesare (@zdicesare)

    It is no longer necessary to specify the binary name when passing flags to containers. For example, to execute the help command of the collector, instead of

    $ docker run -it --rm jaegertracing/jaeger-collector /go/bin/collector-linux help

    run

    $ docker run -it --rm jaegertracing/jaeger-collector help

  • Detect HTTP payload format from Content-Type (#916) by Yuri Shkuro (@yurishkuro)

    When submitting spans in Thrift format to HTTP endpoint /api/traces, the format argument is no longer required, but the Content-Type header must be set to "application/vnd.apache.thrift.binary".

  • Replace domain model with Protobuf/gogo-generated model (#856) by Yuri Shkuro (@yurishkuro)
