All STAT data are collected from standard Solaris or Linux programs (vmstat, iostat, etc.) or some special (like psSTAT for users/processes activity) and saved in MySQL database. Collected data are accessed via Web interface and can be presented in several manner (interactive or static graphs, text, HTML tables).dim_STAT can be used for On-Line monitoring one or several hosts on the same time. As well, data may be easily post loaded from output files of stat commands and analyzed in the same manner. At any time collecting from new stat commands may be added to the tool (via Add-On interface) and enlarge your view on application workload, RDBMS, your personal STAT program, etc.
