4 * What: /sys/fs/orangefs/perf_counter_reset
5 * Date: June 2015
6 * Contact: Mike Marshall <hubcap@omnibond.com>
7 * Description:
8 * echo a 0 or a 1 into perf_counter_reset to
9 * reset all the counters in
10 * /sys/fs/orangefs/perf_counters
11 * except ones with PINT_PERF_PRESERVE set.
12 *
13 *
14 * What: /sys/fs/orangefs/perf_counters/...
15 * Date: Jun 2015
16 * Contact: Mike Marshall <hubcap@omnibond.com>
17 * Description:
18 * Counters and settings for various caches.
19 * Read only.

22 * What: /sys/fs/orangefs/perf_time_interval_secs
23 * Date: Jun 2015
24 * Contact: Mike Marshall <hubcap@omnibond.com>
25 * Description:
26 * Length of perf counter intervals in
27 * seconds.

30 * What: /sys/fs/orangefs/perf_history_size
31 * Date: Jun 2015
32 * Contact: Mike Marshall <hubcap@omnibond.com>
33 * Description:
34 * The perf_counters cache statistics have N, or
35 * perf_history_size, samples. The default is
36 * one.
37 *
38 * Every perf_time_interval_secs the (first)
39 * samples are reset.
40 *
41 * If N is greater than one, the "current" set
42 * of samples is reset, and the samples from the
43 * other N-1 intervals remain available.
44 *
45 *
46 * What: /sys/fs/orangefs/op_timeout_secs
47 * Date: Jun 2015

54 * Date: Jun 2015
55 * Contact: Mike Marshall <hubcap@omnibond.com>
56 * Description:
57 * "Slot" timeout in seconds. A "slot"
58 * is an indexed buffer in the shared
59 * memory segment used for communication
60 * between the kernel module and userspace.
61 * Slots are requested and waited for,
62 * the wait times out after slot_timeout_secs.
