Hello, it's me again.. it seems I really can't get a hang of being a system administrator and I need some really good advice. At the momment my boss is asking me to do report metrics on the performance of our servers and workstations. Any suggestions what should I include and how will I get the data, for example, to report the disk space I need to use df -k, and vmstat data, In short, what other stastics can I get out of the systems.
and last thing is there any faster way to get the filesize of a folder than du. cause I also need to report the size of a particular folder, weekly, it's located in the T3 disk with the size of 250 GB.
