20 * optionally for a specified client, share and zone.
21 *
22 * Usage: nfs-trace.d [<client ip>|all [<share path>|all] [<zone id>]]]
23 *
24 * example: nfs_trace.d 192.168.123.1 /mypool/fs1 0
25 *
26 * It is valid to specify <client ip> or <share path> as "all"
27 * to quantize data for all clients and/or all shares.
28 * Omitting <zone id> will quantize data for all zones.

32 * Unfortunately, trying to write this script using wildcards, for example:
33 * nfsv3:::op-*-start {}
34 * nfsv3:::op-*-done {}
35 * prints the operation-specific args[2] structure as the incorrect type.
36 * Until this is resolved it is necessary to explicitly list each operation.
37 *
38 * See nfs-time.d for an example of using the wildcard format when there are
39 * no operation-specific args (args[2]) being traced.
