Being a sysadmin has its share of joys, however, challenges abound in this digital world!
Thursday, April 24, 2014: A sysadmin is entrusted to constantly monitor the system. Sysadmins have to be aware of everything about the system starting from CPU load and network traffic statistics to how much free disk space is available. In addition, things go haywire from time to time, in which case it is better that the sysadmin finds out from the monitoring system than from an user. The following tools come in handy when such a case arrives.
