5697d53034 Rewrite MapX2Host as a RenderFunc using joinResults 
It's more efficient as many input Nodes map onto a few hosts.

3e62f7b754 Rewrite MapProcess2Name to process all nodes in one pass 
This is more efficient as there are typically many fewer names than
processes.

346a0360ef Refactor: split addToResults into two functions 
This is preparatory to future refactorings: all existing calls are to
Endpoints which have no children and where we don't want a Counter.

We make addChildAndChildren an obvious extension of addChild even
though it adds a dead code path (we never call addChildAndChildren
with an endpoint).

0c43526465 refactor: use new FilterFunc.Apply 
instead of constructing temporary Filter renderers.

This also makes clearer what is going on.

ae153e57f5 refactor: remove Decorator from render.Renderer.Render() signature 2017-11-18 18:04:52 +00:00
Matthias Radestock
a82d245e93 simplify render decoration 
Decoration is in fact quite a simple process that is applied on entry
to rendering: we take a base renderer, transform it with a decorator,
and then render a report with it. The new render.Decorate() function
does exactly that.

There is one exception. When rendering an individual node, e.g. for
showing its details panel in the UI, we must not lose the node during
decoration. That requires some special logic, which previously resided
in the PreciousNodeRenderer, and now lives in handleNode.

aaf4e54df2 pass render filters and maps by value rather than reference 
They are small and don't carry mutable state, so there is no point
passing them by reference.

b9890064c2 Copy net.ParseIP and modify to save memory allocations 
Pass in a slice on the stack instead of allocating one on the heap:
reduces garbage, hence makes the program run faster

Also apply knowledge that critbitgo will do an append() with one extra
byte, so we do that allocation up-front too.  This is innocuous should
we stop using critbitgo or should its internals change.

21a91fe9dd remove HostRenderer memoisation 
since it was only introduced to because producing stats would hit the
renderer twice, which is no longer the case.

9bd8bd825b remove now superfluous Renderer.Stats method 
step 2 (and final step) in producing stats as part of Rendering
 2017-11-08 07:15:28 +00:00
Matthias Radestock
8f7e00f46a Stats are easily produced as part of Rendering 
...so there is no need for a separate Stats method.

step 1: return stats from Render

cbcb5f19fc Rewrite ProcessRenderer/MapEndpoint2Process as a single Renderer

77a8cac65a Use helper to add result nodes in endpoints2Hosts.Render

endpoint sub-nodes, but it seems that data was not used.

b684e3c6fc Rewrite MapEndpoint2Host as a Renderer 
This allows us to avoid creating a host of 'IP' type Nodes then
discarding them after matching; instead we match directly and create
just the result we want.

7b0a08ae9d memoise renderer passed to ConnectionJoin 
We do this here rather than in ConnectionJoin since that way it is
obvious that the renderer isn't memoised already.

b793a9efa8 memoise shared top-level renderers 
and add a comment indicating non-memoisation of other, not shared
top-level renderers.

This memoisation is effective when the browser requests multiple
topologies for the same report.

800979a089 Avoid object creation when scanning DNS names 
Since we do this a lot, scanning the lists in-place saves time.
Also we don't need to sort them since StringSet is implemented as a
sorted set of strings

0d381a34d6 Link scope-ui graphs clickable to prometheus queries (#2664) 
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
