Command
weka statsThe collected statistics can help analyze system performance and determine the source of issues that may occur during Content Software for File system runs. Statistics are divided according to categories. When selecting a category, a list of the possible statistics is displayed, from which you can select the specific statistics.
Note: Content Software for File averages all statistics over one-second intervals. Consequently, the total value or other aggregates relate to a specific minute.
Use the following command line to manage filters and read statistics:
weka stats [--start-time <start-time>] [--end-time <end-time>] [--interval interval] [--resolution-secs resolution-secs] [--category category][--stat stat] [--node-ids node-ids] [--param param] [--accumulated] [--per-node] [--no-zeros] [--show-internal] [--raw-units] [--UTC]
