Not the most elegant/robust solution but it solves the problem without adding
extra methods to the backoff interface (only to check if they are ready from
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
- Run the Weave integrations regardless of if weave is detected.
- Make everything backoff and not spam the logs.
- Add miekg dns to vendor.
- Have the app periodically register with weaveDNS, and the probe do lookups there.
- Decide what the local networks are at runtime, not once at startup.
- Correctly resolve app ids, fixes#825
Megasquish:
[app] remove unused edge endpoint
[WIP] refactoring node details api endpoint
[WIP] plumbing the children through the rendering process
adding IDList.Remove and StringSet.Remove
[WIP] working on adding parents to detailed node renderings
WIP UI components with mock backend data for new details
grouping children by type
UI components for node details health and info
metric formatters for details panel
Column headers and links for details table
[WIP] started on rendering node metadata and metrics in the detail view
DetailedNode.LabelMajor -> DetailedNode.Label
rendering decent labels for parents of detailed nodes
render metrics onto the top-level detailed node
removing dead code
Links to relatives
metrics have a Format not Unit
Show more/less actions for tables and relatives
adjusted metric formatter
TopologyTagger should tag k8s topology nodes
make renderablenode ids more consistent, e.g. container:abcd1234
working on rendering correct summaries for each node
adding report.Node.Rank, so that merging is independent of order
rendering children and parents correctly
output child renderableNode ids, so we can link to them
add group field to metrics, so they can be grouped
Refactored details health items to prepare for grouping
add metrics to processNodeSummaries
hide summary section if there is no data for it
fixing up tests
moving detailed node rendering into a separate package
Node ID/Topology are fields not metadata
- This way I think we don't have to care about Metadata being non-commutative.
- ID and topology are still non-commutative, as I'm not sure how to sanely
merge them, but it's possible we don't care.
host memory usage is a filesize, not a percent
working on fixing some tests
adding children to hosts detail panel
- Had to redo how parents are calculated, so that children wouldn't interfere with it
- have to have the host at the end because it is non-commutative
only render links for linkable children (i.e. not unconnected processes)
resolving TODOs
fixing up lint errors
make nil a valid value for render.Children so tests are cleaner
working on backend tests
make client handle missing metrics property
Stop rendering container image nodes with process summaries/parents
fix parent link to container images
Calculate parents as a set on report.Node (except k8s)
refactoring detailed.NodeSummary stuff
removing RenderableNode.Summary*, we already track it on report.Node
working on tests
add Columns field to NodeSummaryGroup
fixing up render/topologies_test
fix children links to container images
get children of hosts rendering right
working on host renderer tests
Change container report.Node.ID to a1b2c3;<container>
The id should be globally unique, so we don't need the host id.
This lets the kubernetes probe return a container node with the pod id,
which will get merged into the real containers with other reports. The
catch is that the kubernetes api doesn't tell us which hostname the
container is running on, so we can't populate the old-style node ids.
change terminology of system pods and services
Fix kubernetes services with no selector
Fixes handling of kubernetes service, which has no pods
fix parent links for pods/services
refactor detailed metadata to include sets and latest data
fixing up host rendering tests
fleshing out tests for node metadata and metrics
don't render container pseudo-nodes as processes
Update test for id format change.
NewNodeMetadata -> MakeNodeMetadata. It doesn't return a pointer, so
Make is more idiomatic.
Invoke MakeNodeMetadata when necessary. The zero value for a
NodeMetadata is no longer valid.
Split MakeNodeMetadata to two constructors. MakeNodeMetadata when you
don't have anything to prepopulate; MakeNodeMetadataWith when you do.
Also, a fix to the tests in app. We unmarshal a RenderableNode struct,
which has a JSON-ignored NodeMetadata field. The zero value is invalid,
so we need to fix that before performing comparisons.
