    • --cassandra-archive.tls is replaced by --cassandra-archive.tls.enabled
    • --collector.grpc.tls is replaced by --collector.grpc.tls.enabled
    • --collector.grpc.tls.client.ca is replaced by --collector.grpc.tls.client-ca
    • --es.tls is replaced by --es.tls.enabled

  • Remove deprecated flags --health-check-http-port & --admin-http-port, please use --admin.http.host-port (#2752, @pradeepnnv)

  • Remove deprecated flag --es.max-num-spans, please use --es.max-doc-count (#2482, @BernardTolosajr)

  • Remove deprecated flag --jaeger.tags, please use --agent.tags (#2753, @yurishkuro)

  • Remove deprecated Cassandra flags (#2789, @albertteoh):

    • --cassandra.enable-dependencies-v2 - Jaeger will automatically detect the version of the dependencies table

    • --downsampling.ratio removed from jaeger-query

New Features

  • Add TLS Support for gRPC and HTTP endpoints of the Query and Collector servers (#2337, #2772, #2798, @rjs211)

    • If TLS in enabled on either or both of gRPC or HTTP endpoints, the gRPC host-port and the HTTP host-port have to be different
    • If TLS is disabled on both endpoints, common HTTP and gRPC host-port can be explicitly set using the following host-port flags respectively:
      • Query: --query.http-server.host-port and --query.grpc-server.host-port
      • Collector: --collector.http-server.host-port and --collector.grpc-server.host-port

  • Add support for Kafka SASL/PLAIN authentication via SCRAM-SHA-256 or SCRAM-SHA-512 mechanism (#2724, @WalkerWang731)

  • [agent] Add metrics to show connections status between agent and collectors (#2657, @WalkerWang731)

  • Add plaintext as a supported kafka auth option (#2721, @pdepaepe)

  • Add status command (#2684, @sniperking1234)

    • Usage: 
      $ ./cmd/collector/collector-darwin-amd64 status
{"status":"Server available","upSince":"2021-02-19T17:57:12.671902+11:00","uptime":"25.241233383s"}

Backend Changes

Breaking Changes

  • Configurable ES doc count (#2453, @albertteoh)

    The --es.max-num-spans flag has been deprecated in favour of --es.max-doc-count. --es.max-num-spans is marked for removal in v1.21.0 as indicated in the flag description.

    If both --es.max-num-spans and --es.max-doc-count are set, the lesser of the two will be used.

    The use of --es.max-doc-count (which defaults to 10,000) will limit the results from all Elasticsearch queries by the configured value, limiting counts for Jaeger UI:

    • Services
    • Operations
    • Dependencies (edges in a dependency graph)
    • Span fetch size for a trace

  • The default value for the flag query.max-clock-skew-adjustment has changed to 0s, meaning that the clock skew adjustment is now disabled by default. See #1459.

Breaking Changes

List of service operations can be classified by span kinds (#1943, #1942, #1937, @guo0693)
  • Endpoint changes:
    • Both Http & gRPC servers now take new optional parameter spanKind in addition to service. When spanKind is absent or empty, operations from all kinds of spans will be returned.
    • Instead of returning a list of string, both Http & gRPC servers return a list of operation struct. Please update your client code to process the new response. Example response: 
      curl 'http://localhost:6686/api/operations?service=UserService&spanKind=server' | jq
{
    "data": [{
        "name": "UserService::getExtendedUser",
        "spanKind": "server"
    },
    {
        "name": "UserService::getUserProfile",
        "spanKind": "server"
    }],
    "total": 2,
    "limit": 0,
    "offset": 0,
    "errors": null
}
    • The legacy http endpoint stay untouched: 
      /services/{%s}/operations
  • Storage plugin changes:
    • Memory updated to support spanKind on write & read, no migration is required.
    • Badger & ElasticSearch to be implemented: For now spanKind will be set as empty string during read & write, only name will be valid operation name.
    • Cassandra updated to support spanKind on write & read (#1937, @guo0693): If you don't run the migration script, nothing will break, the system will used the old table operation_names and set empty spanKind in the response. Steps to get the updated functionality:
      1. You will need to run the command below on the host where you can use cqlsh to connect to Cassandra: 
        KEYSPACE=jaeger_v1 CQL_CMD='cqlsh host 9042 -u test_user -p test_password --request-timeout=3000'
bash ./v002tov003.sh
        The script will create new table operation_names_v2 and migrate data from the old table. spanKind column will be empty for those data. At the end, it will ask you whether you want to drop the old table or not.
      2. Restart ingester & query services so that they begin to use the new table
Trace and Span IDs are always padded to 32 or 16 hex characters with leading zeros (#1956, @yurishkuro)

Previously, Jaeger backend always rendered trace and span IDs as the shortest possible hex string, e.g. an ID with numeric value 255 would be rendered as a string ff. This change makes the IDs to always render as 16 or 32 characters long hex string, e.g. the same id=255 would render as 00000000000000ff. It mostly affects how UI displays the IDs, the URLs, and the JSON returned from jaeger-query service.

Motivation: Among randomly generated and uniformly distributed trace IDs, only 1/16th of them start with 0 followed by a significant digit, 1/256th start with two 0s, and so on in decreasing geometric progression. Therefore, trimming the leading 0s is a very modest optimization on the size of the data being transmitted or stored.

However, trimming 0s leads to ambiguities when the IDs are used as correlations with other monitoring systems, such as logging, that treat the IDs as opaque strings and cannot establish the equivalence between padded and unpadded IDs. It is also incompatible with W3C Trace Context and Zipkin B3 formats, both of which include all leading 0s, so an application instrumented with OpenTelemetry SDKs may be logging different trace ID strings than application instrumented with Jaeger SDKs (related issue #1657).

Overall, the change is backward compatible:

  • links with non-padded IDs in the UI will still work
  • data stored in Elasticsearch (where IDs are represented as strings) is still readable

However, some custom integration that rely on exact string matches of trace IDs may be broken.

Change default rollover conditions to 2 days (#1963, @pavolloffay)

Change default rollover conditions from 7 days to 2 days.

Given that by default Jaeger uses daily indices and some organizations do not keep data longer than 7 days the default of 7 days seems unreasonable - it might result in a too big index and running curator would immediately remove the old index.

  • The default value for the Ingester's flag ingester.deadlockInterval has been changed to 0 (#1868, @jpkrohling)

    With the new default, the ingester won't panic if there are no messages for the last minute. To restore the previous behavior, set the flag's value to 1m.

  • Mark --collector.grpc.tls.client.ca flag as deprecated for jaeger-collector. (#1840, @yurishkuro)

    The deprecated flag will still work until being removed, it's recommended to use --collector.grpc.tls.client-ca instead.

1.14.0 (2019-09-02)

Backend Changes

Breaking Changes

  • Create ES index templates instead of indices (#1627, @pavolloffay)

    This can break existing Elasticsearch deployments if security policies are applied. For instance Jaeger X-Pack configuration now requires permission to create index templates - manage_index_templates.

New Features

  • Add Elasticsearch version configuration to rollover script (#1769, @pavolloffay)

  • Add Elasticsearch version flag (#1753, @pavolloffay)

  • Add Elasticsearch 7 support (#1690, @gregoryfranklin)

    The index mappings in Elasticsearch 7 are not backwards compatible with the older versions. Therefore using Elasticsearch 7 with data created with older version would not work. Elasticsearch 6.8 supports 7.x, 6.x, 5.x compatible mappings. The upgrade has to be done first to ES 6.8, then apply data migration or wait until old daily indices are removed (this requires to start Jaeger with --es.version=7 to force using ES 7.x mappings for newly created indices).

    Jaeger by default uses Elasticsearch ping endpoint (/) to derive the version which is used for index mappings selection. The version can be overridden by flag --es.version.

  • Support for Zipkin Protobuf spans over HTTP (#1695, @jan25)

  • Added support for hot reload of UI config (#1688, @jpkrohling)

  • Added base Grafana dashboard and Alert rules (#1745, @jpkrohling)

  • Add the jaeger-mixin for monitoring (#1668, @gouthamve)

  • Added flags for driving cassandra connection compression through config (#1675, @sagaranand015)

  • Support index cleaner for rollover indices and add integration tests (#1689, @pavolloffay)

  • Add client TLS auth to gRPC reporter (#1591, @tcolgate)

  • Collector kafka producer protocol version config (#1658, @marqc)

  • Configurable kafka protocol version for msg consuming by jaeger ingester (#1640, @marqc)

  • Use credentials when describing keyspaces in cassandra schema builder (#1655, @MiLk)

    The list of metrics affected: traces.received, traces.rejected, traces.saved-by-svc.

  • Remove deprecated index prefix separator : from Elastic (#1620, @pavolloffay)

    In Jaeger 1.9.0 release the Elasticsearch index separator was changed from : to -. To keep backwards compatibility the query service kept querying indices with : separator, however the new indices were created only with -. This release of Jaeger removes the query capability for indices containing :, therefore it's recommended to keep using older version until indices containing old separator are not queried anymore.

    The following flags have been removed in the Collector and the Ingester:

    --kafka.brokers
--kafka.encoding
--kafka.topic
--ingester.brokers
--ingester.encoding
--ingester.topic
--ingester.group-id

    In the Collector, they are replaced by:

    --kafka.producer.brokers
--kafka.producer.encoding
--kafka.producer.topic

    In the Ingester, they are replaced by:

    --kafka.consumer.brokers
--kafka.consumer.encoding
--kafka.consumer.topic
--kafka.consumer.group-id

  • Add Admin port and group all ports in one file (#1442, @yurishkuro)

    This change fixes issues #1428, #1332 and moves all metrics endpoints from API ports to admin ports. It requires re-configuring Prometheus scraping rules. Each Jaeger binary has its own admin port that can be found under --admin-http-port command line flag by running the ${binary} help command.

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.

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_.
