2000-04-24 Martin Baulig <baulig@suse.de>
* proc_cwd.c: New file. This feature was requested by Nautilus
hacker Maciej Stachowiak and it returns the current working
directory of a process.
2000-02-22 Martin Baulig <martin@home-of-linux.org>
* Makefile.am: Only install the libs in $(LIBGTOP_BACKEND_DIR)
when we LIBGTOP_USE_GMODULE and in $(libdir) otherwise.
2000-02-06 Martin Baulig <martin@home-of-linux.org>
* ppp.c: Make this work with multiple ISDN devices.
2000-01-22 Martin Baulig <martin@home-of-linux.org>
* Makefile.am: Install the library in $(backenddir).
1999-12-11 Martin Baulig <martin@home-of-linux.org>
* cpu.c: Only set smp flags when we're really on a SMP machine.
1999-11-28 Martin Baulig <martin@home-of-linux.org>
* procstate.c (glibtop_get_procstate_s): Stat "/proc/<pid>" instead
of "/proc/<pid>/state" to get `uid' and `gid'. Thanks to Jason Becker
for pointing out that GTop reported wrong uid's.
1999-11-21 Martin Baulig <martin@home-of-linux.org>
* interfaces.c: New file.
(glibtop_init_interface_names_s): New function.
(glibtop_get_interface_names_s): New function.
1999-11-21 Martin Baulig <martin@home-of-linux.org>
* proclist.c: (glibtop_get_proclist_s): Support GLIBTOP_KERN_PROC_PPID.
1999-10-19 Martin Baulig <martin@home-of-linux.org>
* uptime.c (glibtop_get_uptime_s): Don't cast uptime and idletime
to float as suggested by John Kodis.
1999-09-28 Radek Doulik <rodo@praha.eridan.cz>
* proclist.c (glibtop_get_proclist_s): fixed idle processes filtering
1999-07-29 Martin Baulig <martin@home-of-linux.org>
* proctime.c (glibtop_get_proctime_s): Don't provide `rtime'
any longer since we must not use `rtime = utime + stime'.
1999-02-20 Martin Baulig <martin@home-of-linux.org>
* netload.c: Don't include <linux/ip_fw.h> for libc5 systems
since it is no longer required and makes trouble on Slakware.
1999-01-06 Martin Baulig <martin@home-of-linux.org>
* netload.c (glibtop_get_netload_s): Use `server->os_version_code'
instead of GLIBTOP_LINUX_VERSION_CODE.
1999-01-06 Martin Baulig <martin@home-of-linux.org>
Unconditionally enable SMP support for linux.
* open.c (_glibtop_open_s): Always determine the number of CPUs
we have here, not only when SMP support was enabled.
* cpu.c, proctime.c: Use `server->ncpu' to determine whether to
enable SMP support.
1998-12-28 Martin Baulig <martin@home-of-linux.org>
* netload.c: When using glibc, don't include <netinet/ip_fw.h>
any longer but all headers that were included there; we only
needed this file to get those headers.
1998-12-09 Martin Baulig <martin@home-of-linux.org>
* procargs.c (glibtop_get_proc_args_s): Added implementation
for this function.
1998-12-03 Martin Baulig <martin@home-of-linux.org>
* netload.c: No longer include <linux/version.h>, but use
GLIBTOP_LINUX_VERSION_CODE which is set by configure instead.
Define _GLIBTOP_IP_FW_ACCTIN and _GLIBTOP_IP_FW_ACCTOUT here
and use them instead of IP_FW_F_ACCTIN and IP_FW_F_ACCTOUT.
1998-11-30 Martin Baulig <martin@home-of-linux.org>
* netload.c: Use correct header files both for libc5 and glibc.
With Linux >= 2.1.114 we no longer use IP accounting since it
already has byte counts in /proc/net/dev.
1998-11-22 Martin Baulig <baulig@merkur.uni-trier.de>
* netload.c (glibtop_get_netload_s): Added implementation
for this function.
The code here is smart enough to use /proc/net/ip_acct if
IP accounting is enabled in the kernel and activated on the
requested device and /proc/net/dev if not.
To get separate statistics for received and transmitted
packets you need to use two accounting rules:
ipfwadm -A in -a -P all -W eth0
ipfwadm -A out -a -P all -W eth0
But before you activate IP accounting, please have a look
at /proc/net/dev - if if already contains byte counters,
then don't use IP accounting.
1998-10-28 Martin Baulig <martin@home-of-linux.org>
* ppp.c: Added code for ISDN here.
1998-10-26 Martin Baulig <martin@home-of-linux.org>
* netload.c: New file. Currently empty.
1998-10-26 Martin Baulig <martin@home-of-linux.org>
* procargs.c: New file. Currently empty.
1998-10-25 Martin Baulig <martin@home-of-linux.org>
* ppp.c: New file. Currently empty.
1998-10-11 Martin Baulig <martin@home-of-linux.org>
* procdata.c: Removed this obsolete file.
1998-10-02 Martin Baulig <martin@home-of-linux.org>
* proclist.c (glibtop_init_proclist_s): You can now also use the
`GLIBTOP_EXCLUDE_*' flags for the `which' parameter.
1998-10-01 Martin Baulig <baulig@Stud.Informatik.uni-trier.de>
* proclist.c (glibtop_init_proclist_s): Honor the `which' parameter
to select which processes to fetch.
1998-09-12 Martin Baulig <martin@home-of-linux.org>
* sysinfo.c: New file.
1998-09-09 Martin Baulig <baulig@Stud.Informatik.uni-trier.de>
* proctime.c (glibtop_get_proc_time_s): Added SMP support.
* open.c (glibtop_init_s): Initialize `ncpu' on SMP systems.
* cpu.c (glibtop_get_cpu_s): Added SMP support.
* ChangeLog: New file.

*
* ------------------------------------------------------------
* This is from the manpage of isdninfo(4):
*
* DESCRIPTION
* /dev/isdninfo is a character device with major number 45
* and minor number 255. It delivers status information from
* the Linux ISDN subsystem to user level.
*
* DATA FORMAT
* When reading from this device, the current status of the
* Linux ISDN subsystem is delivered in 6 lines of text. Each
* line starts with a tag string followed by a colon and
* whitespace. After that the status values are appended sep-
* arated by whitespace.
*
* flags is the tag of line 5. In this line for every driver
* slot, it's B-Channel status is shown. If no driver
* is registered in a slot, a ? is shown. For every
* established B-Channel of the driver, a bit is set
* in the shown value. The driver's first channel is
* mapped to bit 0, the second channel to bit 1 and so
* on.
* ------------------------------------------------------------
*
* So we open /dev/isdninfo, discard the first four lines of text
* and then check whether we have something that is not `0' or `?'
* in one of the flags fields.
*
* Sounds complicated, but I don't see any other way to check whether
* we are connected. Also, this is the method some other ISDN tools
* for Linux use.
*
* Martin
