- base load graph x-axis on data, not a hardcoded window
- format memory dynamically to scale
- add some tests for the immutability of metrics
- use ps.List for Sample storage, so it is immutable. Have to implement custom marshalling
- adding tests for report.Metrics
- check the ordering of the json samples
- Make the nil value for Metrics valid.
- Sort samples from oldest to newest on the wire.
* Now the Connections table appears at the end of the pane
* Connection details are expandable (still not implemented in the UI but backwards
compatible).
Also, 1 packet may be counted in N topologies, so you can't rely on the
sum of all packet counts across topologies having any relation to the
sampling data.
Another implicit invariant in the data model is that edges are always of the
form (local -> remote). That is, the source of an edge must always be a node
that originates from within Scope's domain of visibility. This was evident by
the presence of ingress and egress fields in edge/aggregate metadata.
When building the sniffer, I accidentally and incorrectly violated this
invariant, by constructing distinct edges for (local -> remote) and (remote ->
local), and collapsing ingress and egress byte counts to a single scalar. I
experienced a variety of subtle undefined behavior as a result. See #339.
This change reverts to the old, correct methodology. Consequently the sniffer
needs to be able to find out which side of the sniffed packet is local v.
remote, and to do that it needs access to local networks. I moved the
discovery from the probe/host package into probe/main.go.
As part of that work I discovered that package report also maintains its own,
independent "cache" of local networks. Except it contains only the (optional)
Docker bridge network, if it's been populated by the probe, and it's only used
by the report.Make{Endpoint,Address}NodeID constructors to scope local
addresses. Normally, scoping happens during rendering, and only for pseudo
nodes -- see current LeafMap Render localNetworks. This is pretty convoluted
and should be either be made consistent or heavily commented.
- Move pidtree to its own module and disaggregate it into tree, walker and reporter.
- Extend testing for probe/process
- Extend process metadata; add command line & # threads.
This makes container image details show the containers (and processes) correctly.
Also:
- introduces a 'test' package, moved Diff function there.
- adds some tests for this new rendered view.
