It connects with SSH (using SSH public/private key auth) to several servers at once and vizualizes all server CPUs and memory statistics right next each other (either summarized or each core separately). Loadbars is not a tool for collecting CPU loads and drawing graphs for later analysis. However, since such tools require a significant amount of time before producing results, Loadbars lets you observe the current state immediately. Loadbars does not remember or record any load information. It just shows the current CPU usages like top or vmstat does. @@ -52,8 +60,6 @@ to = Total CPU usage, which is (100% - id) pk = Max us+sy peak of last avg. samples (extended) -avg = System load average; desc. order: 1, 5 and 15 min. avg. - 1px horizontal line: Maximum sy+us+io of last 'avg' samples (extended) =head2 Memory stuff |
