Example A-4 on page 772 shows statistics for the two nodes members of cluster ITSO-SV1 . For each node, the following columns are displayed: 

GLYPH<SM590000> stat_name : The name of the statistic field 

GLYPH<SM590000> stat_current : The current value of the statistic field 

GLYPH<SM590000> stat_peak : The peak value of the statistic field in the last 5 minutes 

GLYPH<SM590000> stat_peak_time : The time that the peak occurred 

The lsnodestats  command can also be used with a node name or ID as an argument. For example, you can enter the command lsnodestats node1 to display the statistics of node with name node1  only. 

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: 

GLYPH<SM590000> Bandwidth: Sum of bandwidth 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> IOPS: Total IOPS of all nodes 

GLYPH<SM590000> CPU percentage: Average CPU percentage of all nodes 

Example A-5 shows the resulting output of the lssystemstats  command.
