Linux network stats (#44) 
* Add libnl-3 and libnl-route-3 dependency if Linux (libnl-3-dev on ubuntu)
* Add libnl-3 flags, refactor stats/dune

Use dune-configurtator to get C flags. In the dune-configurator script,
we detect whether we're running on Linux or FreeBSD.

Hannes Mehnert 784429744c versioning: revise it all, use a 'current' in Vmm_commands, all daemons reply with the received version on that particular stream 2019-11-11 23:20:03 +01:00

Hannes Mehnert 992e1b0a2b - Vmm_ring is now polymorph (alows to store log_entry :D) 
- Vmm_console/log/stats do not read multiple times
  console_add loops
  console_subscribe terminates (a stream of messages is sent)
  log data stream loops
  log_subscribe terminates (a stream of data is sent)
  stat_add loops
  stat_remove loops
  stat_subscribe terminates (a stream of stats is sent)
terminates means: reads once more, and closes socket after second read returned
loop processes further incoming data

Hannes Mehnert 0583fbfaf1 stats: transmit vmid in add/remove/stats, pid only in add

 influxdb line format via tcp to specified host and port

 2018-04-01 23:59:12 +02:00
Hannes Mehnert 66df394d36 vmm_stats: allow vmmapi to fail (and report nothing), more convenient for linux code path 2018-03-24 23:39:16 +01:00
Hannes Mehnert 51d1dc63dc vmm_stats: fix fd leaks (fixes #10) 
- vm_open only once per vm (vmmapi_open), returning vmctx
 - get stats descriptions only once in lifetime (vmmapi_statnames)
 - close file descriptor on `remove_pid` (vmmapi_close)
