Dependency graph endpoints 2 #128

wants to merge 110 commits into


None yet
2 participants

jerryli9876 commented Aug 28, 2012

Part 1 redux of several pull requests that will make up the dependency graph.

Fixed some minor issues with the hadoop scripts, and with email.mustache.
Added dependency graph endpoints on the server side.

There are a few files such as QueryService and Index that changed that I didn't touch...not sure what's going on there.

johanoskarsson and others added some commits Jun 6, 2012

Franklin Hu zipkin-query gem
Split access to Zipkin Query service out into separate gem
- Fix generated ruby namespacing in `zipkin-thrift`
- Thrift files are symlinked in `zipkin-gems/zipkin-query/thrift`, and
  the generated code is in `zipkin-gems/zipkin-query/vendor`

Franklin Hu Split common classes into zipkin-common
- Moved:
  - `Annotation` (and spec)
  - `Endpoint` (and spec)
  - `IncompleteTraceDataException`
  - `Span` (and spec)
- Left `Trace`, `TraceSummary` in `zipkin-server` since they're
  specific to the query service
- Left `ZooKeeperClientService` since don't want to introduce a ZK
  dependency in common project
- `IncompleteTraceDataException` can be later removed when we pull
  out the Thrift dependencies

@johanoskarsson johanoskarsson Reduce the garbage generated in the collector. Before we got about 40…
…0kb of garbage per sampled request, after it's at about 300kb.

Includes these changes
* don't recalculate the lowercase version of service names in span each time they are used
* don't create the incoming data log message unless debug is turned on
* reuse some data instead of recalculating when indexing in Cassandra

Franklin Hu zipkin-scrooge
Pull scrooge/thrift dependency out of `zipkin-common` and `zipkin-server` into `zipkin-scrooge`. This will allow us to do further refactoring easily.
- Add `AnnotationType` and `BinaryAnnotation` classes for direct mirroring of thrift structs
- Unify `toThrift` and `fromThrift` methods in `ThriftAdapter` that handles the different structs defined in the thrift file. We can in the future make this configurable in the collector service.
- Use one set of `Constants` rather than the thrift generated ones
- Fix tests
  - Move thrift related tests to `ThriftAdapterSpec`

Franklin Hu Move Scribe collector/config to zipkin-scribe
Move the Scribe specific code to a new module: `zipkin-scribe` including:
- ScribeCollectorService
- ScribeCollectorService related configs
- collector-dev config
- Main class
- related tests

The collector can no longer be run from `zipkin-server`.

Franklin Hu Modularize remaining collector Scribe dependencies
This change makes it easier to extend the collector to accept different
input types. Doing so would only require writing an `Adapter` and a

- Add `ProcessorFilter`
  - Composable filter on top of `Processor`s that can transform the
    input data type
- Move all deserialization and extraction of data from
  `CollectorService` and `WriteQueueWorker` to Scribe related
  `ProcessFilter` and `Processor`.
- `WriteQueueWorker` now takes only one `Processor` rather than a
  sequence of them.
- Add `FanoutProcessor` to blast work to multiple `Processor`s
- Update README with module diagram

MostCommonCalls : For each service finds the services that it most commonly calls

PopularKeys : Per service, find the 100 most common keys used to annotate spans involving that service

Timeouts : Find which service calls timeout the most

WorstRuntimes : Obtain the IDs and the durations of the one hundred service calls which take the longest per service

Franklin Hu fixed zipkin-web to actually return values from servers
Ruby 1.9.3 fixed a problem where do loops were sometimes not returning their
last value. However, for compatibility with 1.9.2, the with_transport do loops
need their last value to be assigned to a variable with a greater scope than the
do loop, ie to be initialized outside of the do loop and then assigned within.
Either the necessary ruby version should be specified in the documentation, or
this fix needs to be pulled in.
