Once you have NetSaint up and running, you may need to stop the process or reload the configuration data "on the fly". This section describes how to do just that.
Stopping And Restarting With The Init Script
If you have installed the sample init script to your /etc/rc.d/init.d directory you can stop and restart NetSaint easily. If you haven't, skip this section and read how to do it manually below. I'll assume that you named the init script netsaint in the examples below...
Desired Action | Command | Description |
Stop NetSaint | /etc/rc.d/init.d/netsaint stop | This kills NetSaint and deletes the current status log |
Restart NetSaint | /etc/rc.d/init.d/netsaint restart | This kills NetSaint, deletes the current status log, and then starts NetSaint up again |
Reload Configuration Data | /etc/rc.d/init.d/netsaint reload | Sends a SIGHUP to the NetSaint process, causing it to flush its current configuration data, reread the configuration files, and start monitoring again |
Stopping, restarting, and reloading NetSaint are fairly simple with an init script and I would highly recommend you use one if at all possible.
Manually Stopping and Restarting NetSaint
If you aren't using an init script to start NetSaint, you'll have to do things manually. First you'll have to find the process ID that NetSaint is running under and then you'll have to use the kill command to terminate the application or make it reload the configuration data by sending it the proper signal. Directions for doing this are outlined below...
Finding The Process ID
First off, you will need to know the process id that NetSaint is running as. To do that, just type the following command at a shell prompt:
ps axu | grep netsaint
The output should look something like this:
netsaint 6808 0.0 0.7 840 352 p3 S 13:44 0:00 grep netsaint netsaint 11149 0.2 1.0 868 488 ? S Feb 27 6:33 ./netsaint netsaint.cfgFrom the program output, you will notice that NetSaint was started by user netsaint and is running as process id 11149.
Stopping NetSaint
In order to stop NetSaint, use the kill command as follows...
kill 11149
You should replace 11149 with the actual process id that NetSaint is running as on your machine.
Restarting NetSaint
If you have modified the configuration data, you will want to 'restart' NetSaint and have it re-read the new configuration. If you have changed the source code and recompiled the main netsaint executable you should not use this method. Instead, stop NetSaint by killing it (as outlined above) and restart it manually. Restarting NetSaint using the method below does not actually reload NetSaint - it just causes NetSaint to flush its current configuration, re-read the new configuration, and start monitoring all over again. To restart NetSaint, you need to send the SIGHUP signal to NetSaint. Assuming that the process id for NetSaint is 11149 (taken from the example above), use the following command:
kill -HUP 11149
Remember, you will need to replace 11149 with the actual process id that NetSaint is running as on your machine.
