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
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.
* Extend logging middleware to optionally only log failed HTTP requests
* Add a preconfigured logger for logging failed requests, use it in the app.
* Wide definition of success
* Rework Scope metrics according to Prometheus conventions.
- counters should end with _total
- elaborated and added units to help strings
- recommended for cache hit/miss metrics: track only the total and the
hits and in separate metrics, since the most common query will be
"hits / total"
- track all times in seconds (base units), which has become the standard
recommendation
- other small changes
There could be more changes that would require more thinking (what
dimensions to use, summaries vs. histograms, etc.), but this is probably
enough controversial material already :)
* Use timeRequestStatus() in sqs_control_router.go.
* Add in-process caching to dynamodb collector
* Add metrics for dynamodb consumed capacity and report size
* Log and return errors during report collection
* Increase compression to the max
* Put reports in S3 and just use DynamoDB as an index.
* Review feedback
Fix a few bugs in the consul pipe router:
- Don't share a pointer
- Write nil to pipe when closing a bridge connection to ensure the connection shutdown.
- Ensure we shutdown bridge connections correctly
