Updating system configuration
(Handles MOSIX cluster) This tool is outstanding for monitoring, adjusting nice values (priorities), issue signals to the process, view files the process is using, the memory, environmnet variables and sockets the process is using. It is so simple to use, no instructions are necessary.It can monitor a program to make sure it isn't doing something bad.
Configuring QPS to run applications against a process: Select "Command" + "Edit Commands..." + "Add..." Multi-tasking operating systems executes processes in a time slice fashion sharing the processing resources base on their current privilege.Privileges are not constant and elevate if they have not received an execution allocation in the processor after a given time.This is to ensure that all processes get executed regardless of priority although a process can get squeezed out of the time allocation alltogether if the system is overloaded.Higher priority processes may get more time allocated on the processor than a lower priority process but it is likely that the lower process will get some processor allocation.The basic Linux monitoring commands such as In the previous example, the HUP signal was sent to the process.The software was written to trap for the signal so that it could respond to it.
If the software (command) is not written to respond to a particular signal, then the sending of the signal to the process is futile.
Identify all known signals: Also see the GUI tool QPS.
After installation, Linux requires configuration and systems administration.
Corporate systems need monitoring, backups, updates, as well as system and user management.
Ubuntu (apt), Cent OS, Fedora and Red Hat (rpm/YUM) Linux server administration and desktop systems adminstration are covered in this tutorial.
Processes execute within their own process environment, they have their own memory, current working directory, priority, process ID, parent process ID and the file access privileges of the user ID under which they execute.
