debug/io-stats: Add FOP sampling feature

2015-11-01T17:14:34+00:00

Summary:
- Using sampling feature you can record details about every Nth FOP.
  The fields in each sample are: FOP type, hostname, uid, gid, FOP priority,
  port and time taken (latency) to fufill the request.
- Implemented using a ring buffer which is not (m/c) allocated in the IO path,
  this should make the sampling process pretty cheap.
- DNS resolution done @ dump time not @ sample time for performance w/
  cache
- Metrics can be used for both diagnostics, traffic/IO profiling as well
  as P95/P99 calculations
- To control this feature there are two new volume options:
  diagnostics.fop-sample-interval - The sampling interval, e.g. 1 means
  sample every FOP, 100 means sample every 100th FOP
  diagnostics.fop-sample-buf-size - The size (in bytes) of the ring
  buffer used to store the samples.  In the even more samples
  are collected in the stats dump interval than can be held in this buffer,
  the oldest samples shall be discarded.  Samples are stored in the log
  directory under /var/log/glusterfs/samples.
- Uses DNS cache written by sshreyas@fb.com (Thank-you!), the DNS cache
  TTL is controlled by the diagnostics.stats-dnscache-ttl-sec option
  and defaults to 24hrs.

Test Plan:
- Valgrind'd to ensure it's leak free
- Run prove test(s)
- Shadow testing on 100+ brick cluster

xlators: add JSON FOP statistics dumps every N seconds

2015-10-08T12:44:27+00:00

Summary:
- Adds a thread to the io-stats translator which dumps out statistics
  every N seconds where N is configurable by an option called
  "diagnostics.stats-dump-interval"
- Thread cleanly starts/stops when translator is unloaded
- Updates macros to use "Atomic Builtins" (e.g. intel CPU extentions) to
  use memory barries to update counters vs using locks.  This should
  reduce overhead and prevent any deadlock bugs due to lock contention.

Test Plan:
- Test on development machine
- Run prove -v tests/basic/stats-dump.t

build: do not #include "config.h" in each file

2015-05-29T12:43:17+00:00

Instead of including config.h in each file, and have the additional
config.h included from the compiler commandline (-include option).

When a .c file tests for a certain #define, and config.h was not
included, incorrect assumtions were made. With this change, it can not
happen again.

protocol: increase default group-cache-timeout to 300 seconds

sssd uses 300 seconds by default too. There is no need to overload sssd
with requests that it would have cached.

nfs: Enable throttling for rpcsvc

2015-04-29T04:31:43+00:00

Busy nfs servers need throttling to prevent duplicate requests
from casuing an increase in memory consumption.

nfs: make it possible to disable nfs.mount-rmtab

2015-04-26T08:40:22+00:00

When there are many NFS-clients doing very often mount/unmount actions,
the updating of the 'rmtab' can become a bottleneck and cause delays. In
these situations, the output of 'showmount' may be less important than
the responsiveness of the (un)mounting.

By setting 'nfs.mount-rmtab' to the value "/-", the cache file is not
updated anymore, and the entries are only kept in memory.

nfs: do not fail to start when optional RPC-programs fail to register

2015-03-26T10:05:56+00:00

Some RPC-programs are not strictly required for the NFS-server. When
these optional protocols fail to get registered at the portmapper, there
is no need to fail the starting of the NFS-server.

Required RPC-programs:
 - NFS
 - MNT

Optional RPC-programs:
 - NLM
 - ACL
