This release fixes a bug on 'kubernetes describe' operations, where the probe would spin re-opening a connection to the UI again and again after the operation had finished.

Also removes some obsolete code which connected to the unsecured local kubelet port in Kubernetes; please update your configuration to a single probe to talk to Kubernetes for the whole cluster if you haven't already. Thanks to @CiMaol for this contribution.

Bug fixes

  • Stop 'kubernetes describe' operations spinning #3784
  • Probe: skip publishing empty reports when publish rate is higher than collection rate #3774

Improvements

  • Probe no longer talks to local kubelet #3754
  • Track rounding error in multitenant billing calculation #3779

Performance

  • Multitenant: merge incoming reports in collector, to save IO and query time #3780
    #3781 #3782

Dependencies

  • update html-webpack-plugin to most recent stable #3776
  • downgrade fluent-logger-golang library used in multitenant mode #3772

Weave Scope 1.13.0 Pre-release
Pre-release

Release 1.13.0

This release brings a few bug-fixes and number of performance improvements, particularly in reducing the data sent when there are many socket connections between two endpoints.

The bump in version number reflects a change in wire protocol for this change in endpoints data, and also a change in the way active controls are encoded.

Thanks to everyone who contributed to this release: @DarthSett, @sarataha, @slalwani97 and @qiell.

Bug fixes

  • Remove trailing zeros in large numbers in UI #3760
  • kubernetes: display pod status as "terminating" where appropriate #3729
  • kubernetes: detect more 'pause' containers #3743
  • Improve calculation of usage in multitenant code #3751 #3753

Performance improvements

  • Elide many connections from/to the same endpoints #3709
  • Remove two specialised data structures; unify with other node data #3714 #3748
  • Simplify some renderers to improve performance #3747
  • Slow down DNS poll interval to reduce network activity #3758

Minor improvements

  • Add "user-agent" header to http calls from Scope probe #3720
  • Set timestamp and window on each report #3752
  • Add tracing for pipe operations #3745

Dependencies updates

  • Convert to Go modules #3742
  • Update to Go 1.13.9 #3766
  • Go: update weaveworks, prometheus, protobuf, jaeger and aws dependencies #3745 #3756

Release 1.12.0

This release is tagged 1.12 to signify a breaking change: it supports Kubernetes 'v1' object types that are needed for Kubernetes 1.16 and drops support for obsolete 'v1beta' types. #3691

Also the serialisation format changes: DNS data was accidentally renamed 'nodes' in release 1.11.6, and this release changes it back to 'DNS'. #3713

Thanks to everyone who contributed to this release: @bensooraj, @chandankumar4, @imazik, @oleggator and @qiell.

Minor improvements

  • Allow user to disable plugins via command-line flag. #3703
  • In the UI, replace JSON.stringify with json-stable-stringify #3701

Bugs and security fixes

  • fix: report http error if /api call fails #3702
  • Fix a rare crash in the ebpf connection tracker by feeding initial connections synchronously on restart. #3712
  • Fix typos in debugging format strings #3695

Performance improvements

  • handle IP addresses in binary rather than strings #3696
  • In the multitenant app, save IO by keeping rapid-update data outside of the persistent store. #3716

Dependencies updates

Build and CI improvements:

  • Run UI build container as current user to avoid files being owned by root. #3635
  • Replace SASS files with CSS and JavaScript #3700
  • Remove obsolete -e flag from docker login in CI #3708
  • Fix favicon.ico in UI dev mode #3705

Release 1.11.6

This is largely a performance improvement release: the biggest change is that the probe now publishes full reports one in three times; the rest are deltas which are much smaller hence use less CPU and memory in the app. #3677

Some other small performance improvements:

  • perf(probe): reduce copying of nodes #3679
  • perf(probe): add 'omitempty' tag to Topology.Nodes #3678
  • perf(probe): update netlink library to bring in performance improvements #3681
  • perf(multitenant): quantise report cache in query side of aws-collector #3671

Other changes:

  • add tracing spans for rendering to the UI via websocket #3682
  • update some javascript dependencies #3664
  • upgrade JavaScript ui-components #3670 #3673
