Matthias Radestock 9d010fabc8 refactor: extract makeEndpointNode helper 2016-09-02 21:12:23 +01:00
Matthias Radestock 5bc3a9d5ac correctly reverse-resolve source of inbound connections 
There were two problems:
- the renderer was looking for reverse names on the destination
- the probe was not annotating source nodes with reverse-resolved names

Fixes #1847

Julius Volz 4fa40e22b2 Rework Scope metrics according to Prometheus conventions. (#1615) 
* Rework Scope metrics according to Prometheus conventions.

- counters should end with _total
- elaborated and added units to help strings
- recommended for cache hit/miss metrics: track only the total and the
  hits and in separate metrics, since the most common query will be
  "hits / total"
- track all times in seconds (base units), which has become the standard
  recommendation
- other small changes

There could be more changes that would require more thinking (what
dimensions to use, summaries vs. histograms, etc.), but this is probably
enough controversial material already :)

* Use timeRequestStatus() in sqs_control_router.go.

Tom Wilkie 277bd70491 Don't every store NEW conntrack flows (only every store updates). (#1541) 
This closes a small window where we might produce reports which contain flows that are NEW but have never seen an UPDATE, which can potentially be invalid.
