Martynas Pumputis 5c2e878c64 Do not expose IPAM or DNS metrics when weave does not run IPAM or DNS 
Otherwise, GET /metrics will crash weaver.
 2016-10-25 16:54:35 +01:00
Martynas Pumputis b1d6605e8f Remove inaccurate Prometheus metrics 
The metrics include:
- weave_packets_total
- weave_bytes_total

The problem with those metrics is that fastdp periodically flushes
flows including their stats thus makes the current implementation
of the metrics unreliable.

Martynas Pumputis 9754da15d6 Encode "list-netdevs" output in JSON 2016-10-20 18:18:57 +01:00
Bryan Boreham 0458d32089 Serve metrics on a different socket to the main API 
Serve metrics+status on status socket and api+status+metrics on api
socket; the reasoning is that metrics or status are read-only hence
may be scraped from an off-machine connection, while we don't want to
open the control port up unprotected.

Bryan Boreham b8d619dde7 Add Prometheus http handler for metrics

FastDP flow metrics, connection termination count

Martynas Pumputis 3492cd93d0 Use safe version of WithNetNS 2016-10-19 16:15:59 +01:00
Martynas Pumputis 947ae11fee Refactor NetDev utilities 
- Make them safe by using the safe version of WithNetNS.
- Improve naming.
 2016-10-19 16:07:53 +01:00
Martynas Pumputis cdd6ed548c Add netdev subcommands to weaveutil 
The subcommands are going to be used with WithNetNS wrapper.

 2016-10-07 12:20:47 +01:00
Martynas Pumputis 4a49ff3083 Replace usage of WithNetNSUnsafe in plugin/net/watcher.go with safer version

Matthias Radestock 85ac8177ad inline (u)int8 array to string conversion 
so that the code compiles regardless of the uts.Release array type,
which varies across platforms.

Fixes #2506
 2016-10-06 08:57:12 +01:00
Bryan Boreham 50a8dc1383 Add weaveutil process-addrs 
Fetches addresses for every veth that is in a network namespace and
attached to the specified bridge.  Works by iterating over every process.
 2016-09-29 14:16:05 +01:00
Bryan Boreham 71491138aa Extract function to return all current process ids 
This implementation should be more efficient because it only uses the
names under /proc, whereas the previous implementation fetched the
full directory entry for each one, and sorted them too.

Adam Harrison 69b688b357 Merge pull request #2509 from weaveworks/issues/2503-persist-peers-fix 
Create restart.sentinel after storing the peer list
 2016-09-21 10:09:05 +01:00
Martynas Pumputis cdeae04238 Create restart.sentinel after storing peer list 
Otherwise, we risk to lose peer list when any failure happens after
the creation but before storing the list and as a consequence,
the weave container gets restarted.

Matthias Radestock 06a63db4cf Merge branch '1.6' 2016-09-08 12:55:05 +01:00
Bryan Boreham ac4246e1f5 Pass in default subnet when creating 'weave' plugin network. 
New behaviour in Docker 1.12 means it disregards a plugin-supplied
address pool that overlaps an existing route, which causes a hang as
noted in #2469. When we pass in the subnet, Docker believes we really
do want that address range and avoids the hang.

Martynas Pumputis fd0a7efa23 Fix "weave ps" output when weave is not running 
The #2418 has changed a behaviour of "weave ps" which outputs
"Link not found" in the case of weave not running. The previous
behaviour was to output an empty line.

Martynas Pumputis 0861d05522 Address PR comments 
- Do not re-enter the root netns when querying weave bridge.
- Enter the root netns when constructing the predicate.

Martynas Pumputis 7f5c37ef1e Fix "weave ps" 
Make sure that any network namespace changes happens at the end of
the cmd invocation. Otherwise, we are risking to end up in a situation
in which OS scheduling threads are in a "wrong" namespace.

See WithNetNS for more details.

Martynas Pumputis 05baa566c6 Refactor common.GetBridgeNetDev 
- Optimize. Use LinkByName instead of iterating over list of available
  links. Linux does not support interfaces with the same names.
- Remove unnecessary indirection in utility functions which return
  common.NetDev.
