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.
We only want to scope (i.e. prefix with hostID) those addresses that are
deemed loopback, to disambiguate them. Otherwise, we want to leave
addresses in unscoped form, so they can be matched, and links between
communicating nodes properly made.
So, we make the isLoopback check in MakeAddressID, and omit hostID if
the address isn't loopback. So far so good.
But this breaks topology rendering, as we were relying on extracting
hostID from adjacency node IDs, to populate origin hosts in the rendered
node output. So we need another way to get origin host from an arbitrary
node.
A survey revealed no reliable way to get that information from IDs in
their new form. However, we have access to node metadata, so this
changeset introduces the OriginHostTagger, which tags each node with its
origin host, via the foreign-key semantics we'll use going forward.
Another baby step towards #123, this change follows from #192 and merges
the two concepts of Origin in a renderable node. We also cut out a layer
of abstraction, and add an OriginTable method to Report, which directly
generates a table of info for the detail pane given any origin node ID.
Other changes from feedback:
- Assume origin IDs are unique and don't reflect.Dedupe
- Improve origin ID lookup
- Move OriginTable to detailed_node.go, as a free function
- rm app/detail_pane.go (empty)
- All HostMetadata information becomes NodeMetadata
- Significant change to mechanics, but same net effect
- LocalNets becomes "local_networks", space-separated list of CIDRs
- Load becomes simple single string
- Use MakeHostNodeID for indexing into Host topology
- (That changes the app /origin/{id} handler; will be removed later)
- Use constructors instead of ScopeDelim everywhere
- Use constructors instead of IDDelim everywhere
- IDDelim is renamed EdgeDelim, for clarity
- Partial import of the new test fixtures, to be completed later
