Example 8-3 on page 304 shows statistics for the two node members of cluster ITSO_9100.  For each node, the following columns are displayed: However, the  lssystemstats  command lists the same set of statistics that is listed with the  lsnodestats  command, but representing all nodes in the cluster. The values for these  statistics are calculated from the node statistics values in the following way: Example 8-4 shows the resulting output of the  lssystemstats  command. Chapter 8. Hints and tips  305 GLYPH<SM590000> IOPS. Total IOPS of all nodes. GLYPH<SM590000> CPU percentage. Average CPU percentage of all nodes. GLYPH<SM590000> Latency. Average latency for the cluster, which is calculated by using data from the whole  cluster, not an average of the single node values. GLYPH<SM590000> Bandwidth. Sum of bandwidth of all nodes. GLYPH<SM590000> stat_peak_time . The time that the peak occurred. GLYPH<SM590000> stat_peak . The peak value of the statistic field in the last 5 minutes. GLYPH<SM590000> stat_current . The current value of the statistic field. GLYPH<SM590000> stat_name . The name of the statistic field.
