Author: trociny Date: Tue May 21 19:05:27 2013 New Revision: 250871 URL: http://svnweb.freebsd.org/changeset/base/250871 Log: MFC r249668, r249669, r249671, r249673, r249675, r249678, r249680, r249683, r249685, r249686: r249668: Use procstat_getprocs(3) for retrieving thread information instead of direct sysctl calls. r249669: Use more generic procstat_getvmmap(3) for retrieving VM layout of a process. r249671: Use procstat_getgroups(3) for retrieving groups information instead of direct sysctl. r249673: Use procstat_getumask(3) for retrieving umaks information instead of direct sysctl. r249675: Use procstat_getrlimit(3) for retrieving rlimit information instead of direct sysctl calls. r249678: Use libprocstat(3) when retrieving binary information for a process. r249680: Use libprocstat(3) to retrieve process command line arguments and environment variables. r249683: Use libprocstat(3) to retrieve ELF auxiliary vector. r249685: Use procstat_getkstack(3) for retrieving process kernel stacks instead of direct sysctl calls. r249686: Make use of newly added libprocstat(3) ability to extract procstat info from a process core file. So now one can run procstat(1) on a process core e.g. to get a list of files opened by a process when it crashed: root@lisa:/ # procstat -f /root/vi.core PID COMM FD T V FLAGS REF OFFSET PRO NAME 658 vi text v r r-------- - - - /usr/bin/vi 658 vi ctty v c rw------- - - - /dev/pts/0 658 vi cwd v d r-------- - - - /root 658 vi root v d r-------- - - - / 658 vi 0 v c rw------- 11 3208 - /dev/pts/0 658 vi 1 v c rw------- 11 3208 - /dev/pts/0 658 vi 2 v c rw------- 11 3208 - /dev/pts/0 658 vi 3 v r r----n-l- 1 0 - /tmp/vi.0AYKz3Lps7 658 vi 4 v r rw------- 1 0 - /var/tmp/vi.recover/vi.GaGYsz 658 vi 5 v r rw------- 1 0 - - PR: kern/173723 Suggested by: jhb Modified: stable/9/usr.bin/procstat/procstat.1 stable/9/usr.bin/procstat/procstat.c stable/9/usr.bin/procstat/procstat.h stable/9/usr.bin/procstat/procstat_args.c stable/9/usr.bin/procstat/procstat_auxv.c stable/9/usr.bin/procstat/procstat_bin.c stable/9/usr.bin/procstat/procstat_cred.c stable/9/usr.bin/procstat/procstat_kstack.c stable/9/usr.bin/procstat/procstat_rlimit.c stable/9/usr.bin/procstat/procstat_sigs.c stable/9/usr.bin/procstat/procstat_threads.c stable/9/usr.bin/procstat/procstat_vm.c Directory Properties: stable/9/usr.bin/procstat/ (props changed) Modified: stable/9/usr.bin/procstat/procstat.1 ============================================================================== --- stable/9/usr.bin/procstat/procstat.1 Tue May 21 19:04:16 2013 (r250870) +++ stable/9/usr.bin/procstat/procstat.1 Tue May 21 19:05:27 2013 (r250871) @@ -25,7 +25,7 @@ .\" .\" $FreeBSD$ .\" -.Dd July 11, 2012 +.Dd April 20, 2013 .Dt PROCSTAT 1 .Os .Sh NAME @@ -38,7 +38,7 @@ .Op Fl C .Op Fl w Ar interval .Op Fl b | c | e | f | i | j | k | l | s | t | v | x -.Op Fl a | Ar pid ... +.Op Fl a | Ar pid | Ar core ... .Sh DESCRIPTION The .Nm @@ -47,6 +47,8 @@ utility displays detailed information ab arguments, or if the .Fl a flag is used, all processes. +It can also display information extracted from a process core file, if +the core file is specified as the argument. .Pp By default, basic process statistics are printed;
