NETWORK AND SYSTEM MONITORING1
Abstract
A wide range of researches have proved the importance of UNIX or Linux shell commands
for the purpose of checking various system or even network specific information. Despite
these details also being available through GUI interfaces, shell scripts are found to provide
the complete details and aid in generating logs which automatically show output of shell
commands specified by the script and can be opened by admins any time. The report
concerns a script file mySysMonitor.sh which prints the output of different system based and
networking specific data in the mySysMonitor.log file. In performing this, the report uses
various UNIX based terminal commands and their respective extensions for printing the
desired results. The report then explains the use of these commands. After this different
screenshots are provided by the report showing contents of the script and log files. Thus the
report verifies the log output and ends with concluding notes.
