Free stop watch software for linux

loadwatch project allows a single child process to run only when the load on a machine is within certain bounds. When the machines load passes the high load mark, then the child process is stopped.

The process is only restarted when the machines load drops below the low load mark. The load is checked at a user definable interval. loadwatch is distributed under the GNU GPL.

Usage:

loadwatch [-d < time>] [-h < load>] [-l < load>] [-n < copies] [-p < pid>] [-- < command>]
-d < int> load sampling interval (10 seconds)
-h < float> high load mark (1.25)
-l < float> low load mark (0.25)
-n < copies> number of children to fork (1)
-u < filename> file that will be used to externally control a
loadwatch process.
-p < pid> pid of process to control (loadwatch will actually
send signals to the group containing this pid)
NOTE: -p and < command> are mutually exclusive, but one has to be
specified.

Example:

loadwatch -d 10 -h 1.25 -l .25 -- ./rc5des

which means: check the load every 10 seconds, stop rc5des when the load is
greater than 1.25 and restart rc5des when the load drops to .25.

lw-ctl < filename> < cmd>
< filename> is the control file, this corresponds to a unix domain
socket.
< cmd> is the command to send to the loadwatch process.
RUN -> put loadwatch into RUN mode, that is the child process
runs regardless of the load.
STOP -> put loadwatch into STOP mode, that is, the child
process will not run regardless of the load.
WATCH -> WATCH mode, the normal load watching mode.

Example:

lw-ctl ./fooey RUN

Causes the loadwatch process (if it was started with "-u ./fooey") to go
into RUN mode. you could put lw-ctl in a cron job that runs in the
morning to put the job in STOP mode and then again in the evening to put
the job back into WATCH mode.

The children which loadwatch forks are all part of the same process group.
loadwatch stops and starts the processes by signalling the process
group with SIGSTOP and SIGCONT respectively.

Send suggestions and bug reports to . if you do anything
interesting with loadwatch, let me know. i use it for controlling the
distributed.net clients, but i figure itd be good to control thinks like
crack as well.

K ADSL Watch is a universal ADSL monitor for KDE 3, and can be used with the AVM DSL/ISDN-Controller and the CAPI4Linux driver.
K ADSL Watch is an "open source" program: the complete source code is available under the GNU Public License. The program is based on the ISDN monitor "kimon", written by Markus Dahlweid for I4L and the HiSax driver. K ADSL Watch can be used in all Linux distributions.
Main features:
- Monitoring of all activities of the AVM DSL/ISDN-Controller including
- Status display for connection set-up and clear-down
- Throughput rate display (incoming and outgoing)
- Identification of the AVM DSL/ISDN-Controller in use
- Connection up-time and throughput display (incl. Log)
- Integration in the KDE panel

wmstpu is an stop watch dockapp.

Jnettop allows administrators of routers to watch online traffic coming across the network in a fashion similar to the way top displays statistics about processes.
jnettop is useful for quickly evaluating the state of the network.
Enhancements:
- added support for JNET protocol (used by jnettop-gui)
- minor refactorings

Upstart project is an event-based replacement for the /sbin/init daemon which handles starting of tasks and services during boot, stopping them during shutdown and supervising them while the system is running.
It is being developed for the Ubuntu distribution, but is intended to be suitable for deployment in all Linux distributions as a replacement for the venerable sysvinit package.
Main features:
- Tasks and Services are started and stopped by events
- Events are generated as tasks and services are run and stopped
- Events may also be generated at timed intervals, or when files are changed
- Events may be received from any other process on the system
- Services may be respawned if they die unexpectedly
- Bi-directional communication with init daemon to discover which jobs are running, why jobs failed, etc.
Enhancements:
- This release fixes an assertion error and an interaction bug between initctl stop and jobs that call it to stop themselves.

hldStart (HLDS Control Panel) is a PHP based web app to start and stop a Half-life1 and 2 dedicated server (hlds) and any of its mod games (CS, DOD) using a web browser.

There is also a steam web client for updating your games

gMUTOO is an elegant service launcher/stopper/monitor that resides in the window manager tray. gMUTOO has been mostly thought for the launch of daemons (ftpd, sshd, httpd and so on), but it can be used to start/stop pretty anything.

For each entry of its launch menu, a monitored file can be specified (usually a PID file). The status of this file (exists/doesnt exist) is monitored with Gamin (a FAM re-implementation); changes in the file status influence the behaviour of gMUTOO, that displays the status of the service and allows to quickly start it if the status is off and to stop it if the status is on.

gMUTOO can also be compiled without Gamin support, but the file monitor wont be available in this case (for each entry in its menu, gMUTOO will then provide start/stop buttons so the user can decide if a service should be started or stopped).
