Doesn't do anything at present, but will be used later.
Change the signature on BillingEmitter.Close() to match. Note we didn't use the error returned.
This reverts commit 6b72246fe6.
The app merges reports within a 15-second window of its own time, so
if one or more probes have a time that is several seconds different
they will get excluded from the window.
Previously the code called `time.Now()` in two different places so the
timestamps didn't match. Now we use the timestamp of the report itself.
Add the collector's local time to the report if it didn't have one.
This requires no report reading / merging.
We plan to expose this in the HTTP API, so the UI gets a cheap way of
checking whether the app is currently receiving data from probes.
scope-app:
* Adds `-app.metrics-graph` cli flag for configuring the base url to
use for graph links; supports :orgID and :query placeholders
* Assigns query URLs to existing metrics and appends empty metrics if missing
scope-ui:
* Extends <CloudFeature /> with option alwaysShow
* Adds <CloudLink /> to simplify routing when in cloud vs not in cloud
* Links metric graphs in the ui's node details view for all k8s
toplogies and containers so far
* Tracks metric graph click in mixpanel `scope.node.metric.click`
* Uses percentages and MB for CPU/Memory urls
* Passes timetravel timestamp to cortex in deeplink
* Hacky working prototype.
* Operate with time.Duration offset instead of fixed timestamp.
* Polished the backend code.
* Made a nicer UI component.
* Small refactorings of the websockets code.
* Fixed the backend tests.
* Better websocketing and smoother transitions
* Small styling refactoring.
* Detecting empty topologies.
* Improved error messaging.
* Addressed some of David's comments.
* Moved nodesDeltaBuffer to a global state to fix the paused status rendering bug.
* Small styling changes
* Changed the websocket global state variables a bit.
* Polishing & refactoring.
* More polishing.
* Final refactoring.
* Addressed a couple of bugs.
* Hidden the timeline control behind Cloud context and a feature flag.
* Addressed most of @davkal's comments.
* Added mixpanel tracking.
Merge all reports received within a specified interval, discarding the
originals. This improves performance of Report() on repeated
invocation since it ends up merging fewer reports.
For example, if reports are received every second (e.g. 3 probes
reporting at the default probe.publishInterval of 3s), and the
app.windows is 15s (the default) and the report generation interval is
5s (e.g. one UI accessing every TOPOLOGY_INTERVAL; the default), then
the original code would have to merge 15 reports per UI access,
whereas this code will only need to merge 8 to 9 reports (3-4 merged
reports from previous invocation plus 5 recently received reports).
Now you can launch the scope app with something like
./prog/scope --mode=app --weave=false --app.collector=file:///tmp/reports
and if the specified dir contains reports with filenames in the form
<timestamp>.{msgpack|json}[.gz],
e.g. "1488557088545489008.msgpack.gz", then these reports are replayed
in a loop at a sequence and speed determined by the timestamps.
The new probe will convert all node's LatestControls to Controls, so
the old app can consume them. Also, the new app will convert all
node's Controls to LatestControl, so it can consume the reports from
old probes.
- Add interfaces to allow for alternative implementations for Collector, ControlRouter
and PipeRouter.
- Pass contexts on http handlers to these interfaces. Although not used by the current
(local, in-memory) implementations, the idea is this will be used to pass headers to
implementations which support multitenancy (by, for instance, putting an authenticating
reverse proxy in form of the app, and then inspecting the headers of the request for
a used id).
