This allows plugins to add controls to nodes that already have some
controls set by other plugin. Previously only the last plugin that
sets the controls in the node would have its controls visible. That
was because of NodeControls' Merge function that actually weren't
merging data from two inputs, but rather returning data that was newer
and discarding the older one.
This commit makes the LatestMap type a sort of a base class, that
should not be used directly. This also adds a generator for LatestMap
"concrete" types with a specific data type in the LatestEntry.
It is not a singleton anymore. Instead it is an object with a registry
backend. The default registry backend is provided, which is equivalent
to what used to be before. Custom backend can be provided for testing
purposes.
The registry also supports batch operations to remove and add handlers
as an atomic step.
* Helps reduce garbage (MakeMetric() now takes a slice and there's a shorter version MakeSingletonMetric())
* Fixes bug computing Max (Min) in samples since using MakeMetric()
was causing a default Max/Min of zero.
* Simplifies code a bit
* alpine: dl-4.alpinelinux.org is dead, use another server
* increase buffer for docker stats
Attempt to avoid the following message:
docker container: dropping stats.
* probe: better timeout error messages
The logs contains the following messages:
Process reporter took longer than 1s
K8s reporter took longer than 1s
Docker reporter took longer than 1s
Endpoint reporter took longer than 1s
This patch prints how long it takes.
* Show k8s labels and container env vars in the details panel.
* Add show more bar to the env vars and labels
* React key was in the wrong place; empty tables render section labels.
* Collect container environment variales (close#1314)
* Containers managed by Marathon can have meaningful names (close#1309)
* Make linter happy and fix tests
Squash of:
* Include plugins in the report
* show plugin list in the UI
* moving metric and metadata templates into the probe reports
* update js for prime -> priority
* added retry to plugin handshake
* added iowait plugin
* review feedback
* plugin documentation
