Chapter 8 Performance Manager Flow Statistics Configuration Send documentation comments to [email protected] Figure 8-1 Baseline Threshold Example Weekly (option) Mon 1/3 8 weeks Mon 1/10 Mon 1/17 Two thresholds per throughput statistic - updated hourly Mon 2/21 @2 PM Threshold setting Average X Mon 2/28 @2 PM Percent over baseline (e.g. 130%) Daily (option) Mon 2/14 14 days Tues 2/15 Wed 2/16 Sun 2/27 @2 PM Threshold setting Average X Mon 2/28 @2 PM 130886 Percent over baseline (e.g. 130%) The threshold is set for Monday at 2 p.m. The baseline threshold is set at 130% of the average for that statistic. The average is calculated from the statistics value that occurred at 2 p.m. on Monday, for every prior Monday (for the weekly option) or the statistics value that occurred at 2 p.m. on each day, for every prior day (for the daily option). Flow Setup Wizards The Performance Manager Flow and Performance Manager Setup wizards greatly simplify configuration. All you need to do is select the categories of statistics to capture and the wizards provide a list of flows and links to monitor. You can remove entries if desired, or just accept the provided list and start data collection. Statistics for host and storage links are not associated with a specific port on a switch, so you do not lose long term statistics if a connection is moved to a different port. Flow Statistics Configuration Flow statistics count the ingress traffic in the aggregated statistics table. You can collect two kinds of statistics: • Aggregated flow statistics to count the traffic for a VSAN. • Flow statistics to count the traffic for a source and destination ID pair in a VSAN.
