* The --list option does not work on server stats.Steve Dickson2009-04-081-29/+80
| | | | | | | | | | | | The print_stats_list() routine was using the client's stats to decide whether to display any stats. This did not work when there was only server stats. This patch breaks up print_stats_list into two different routines allowing both server and clients stats to be listed. Signed-off-by: Steve Dickson <steved@redhat.com>

* Eliminate the displaying zero stats when the explicit protocolSteve Dickson2009-04-081-103/+135
| | | | | | | | | | | | | | | is specified (-2, -3, -4) the -Z and or --list options. When a particular protocol is specified and either the -Z or --list options are used, zeros or blank lines are echoed to the screen when there is not any NFS traffic. This cause any useful data to be scroll off the screen. With this patch only non-zero stats will be shown, which makes the output of these options more condensed and in turn more useful.

* The nfsstat program reads /proc/net/rpc/* files to gets info aboutJeff Layton2008-06-231-4/+5
| | | | | | | | | | | | | | | | calls. This info is output as unsigned numbers (at least on any relatively recent kernel). When nfsstat prints these numbers, they are printed as signed integers. When the call counters reach 2^31, things start being printed as negative numbers. This patch changes nfsstat to read and print all counters as unsigned integers. Tested by hacking up a kernel to initialize call counters to 2^31+1. Thanks to Takafumi Miki for the initial version of this patch.

* nfsstat -m lists all current nfs mounts, with the mount options.Neil Brown2008-06-061-1/+1
| | | | | | | | | | It does this by reading /proc/mounts and looking for mounts of type "nfs". It really should check for "nfs4" as well. For simplicity, just check the first 3 characters of the type. Signed-off-by: NeilBrown <neilb@suse.de> Signed-off-by: Steve Dickson <steved@redhat.com>

* nfsstat: Add -S/--since flag.david m. richter2007-08-161-18/+134
| | | | | | | | | | | | | | | | Read statistics from the file given with -S/--since and display the difference between those and the current statistics. Valid stat files are those in the form of /proc/net/rpc/nfs, /proc/net/rpc/nfsd, or any "pretty" output from nfsstat itself. Statistics that are missing from a "pretty" stat file are treated as zeroes. Similar to Neil Brown's suggestion, one might use this in conjunction with watch(1) like this: $ watch "nfsstat --since /tmp/stats; nfsstat >/tmp/stats" Signed-off-by: David M. Richter <richterd@citi.umich.edu> Signed-off-by: Neil Brown <neilb@suse.de>
* nfsstat: #define stat header labels.david m. richter2007-08-161-20/+35
| | | | | | | | | Make #defines for the stat header labels, use for output, and add to struct statinfo. This will be used by a subsequent patch for -S/--since. Signed-off-by: David M. Richter <richterd@citi.umich.edu> Signed-off-by: Neil Brown <neilb@suse.de>
* nfsstat: Remove some pointer comparisons against global statinfos.david m. richter2007-08-161-12/+15
| | | | | | | | Pass-in an "is_srv" arg instead of doing pointer comparisons against the static statinfo arrays themselves. Signed-off-by: David M. Richter <richterd@citi.umich.edu> Signed-off-by: Neil Brown <neilb@suse.de>
* nfsstat: Obviate and remove copy_stats().david m. richter2007-08-161-25/+18
| | | | | | | | | Rather than copying stats during --sleep, instead introduce a few pointers and rearrange them to avoid the copy. Will be useful with --since, too. Signed-off-by: David M. Richter <richterd@citi.umich.edu> Signed-off-by: Neil Brown <neilb@suse.de>
* nfsstat: rename *_tmp variables to *_old.david m. richter2007-08-161-19/+19
| | | | | | | | | To make a subsequent patch a little clearer, make it explicit that current *_tmp variables are actually always/only the "old" set used in comparisons. Signed-off-by: David M. Richter <richterd@citi.umich.edu> Signed-off-by: Neil Brown <neilb@suse.de>
* nfsstat: rename --diff-stat to --sleepdavid m. richter2007-08-091-7/+7
| | | | | | | | As per Bruce Fields' suggestion, rename the clunky -D/--diff-stat to the more-intuitive -Z/--sleep. Signed-off-by: David M. Richter <richterd@citi.umich.edu> Signed-off-by: Neil Brown <neilb@suse.de>
* nfsstat: fix a bug in diff_stats()david m. richter2007-08-091-4/+25
| | | | | | | | | Fix a bug in diff_stats() that causes false-positives in has_stats(), which can result in a bunch of zeros being displayed instead of suppressed as intended. Signed-off-by: David M. Richter <richterd@citi.umich.edu> Signed-off-by: Neil Brown <neilb@suse.de>

* nfsstat: display 3 additional NFSv4 client op countersdavid m. richter2007-08-091-4/+5
| | | | | | | | | Display three extra NFSv4 client counters that are already exposed in /proc/net/rpc/nfs: GETACL, SETACL, and FS_LOCATIONS. Won't cause trouble on older kernels that might lack those counters. Signed-off-by: David M. Richter <richterd@citi.umich.edu> Signed-off-by: Neil Brown <neilb@suse.de>
* nfsstat: add -D/--diff-statdavid m. richter2007-08-011-2/+91
| | | | | | | | | | | Add -D/--diff-stat: instead of immediately displaying total collected NFS stats and exiting, nfsstat will take a snapshot of current statistics and pause until the user hits ^C, at which point it takes a second snapshot and then prints out the difference of the two; i.e., only the statistics collected during the pause.

* nfsstat: use macros to declare struct statinfo arraysdavid m. richter2007-08-011-22/+30
| | | | | | | | | Use macros to build the arrays of struct statinfos. This will make adding the extra set of temporary variables needed by -D/--diff-stat much easier. Signed-off-by: David M. Richter <richterd@citi.umich.edu> Signed-off-by: Neil Brown <neilb@suse.de>
* nfsstat: standardize naming of opcount arraysdavid m. richter2007-08-011-30/+30
| | | | | | | | | | Standardized Naming 2: Make the client and server "call counts" arrays' variable names reflect/include the actual text labels from the /proc files -- e.g., "cltv2info" becomes "cltproc2info". A subsequent patch will rely on this naming scheme. Signed-off-by: David M. Richter <richterd@citi.umich.edu> Signed-off-by: Neil Brown <neilb@suse.de>
* nfsstat: standardize naming of server variablesdavid m. richter2007-08-011-40/+40
| | | | | | | | | | Standardized Naming 1: Instead of having a variety of different server-related variable name prefixes ("srv", "svr", "svc", "SVC"), set them all to "srv" or "SRV". A subsequent patch will rely on this naming scheme. Signed-off-by: David M. Richter <richterd@citi.umich.edu> Signed-off-by: Neil Brown <neilb@suse.de>
