Thefollowing listing shows the CellCLI command for reporting IORM metrics. These metrics are maintainedon each cell, so we’ll need to run this command on each storage cell and merge the results for furtheranalysis.CellCLI> spool iorm_enkcel01_metrics.datCellCLI> LIST METRICCURRENT -WHERE objectType LIKE 'IORM_.*'CellCLI> spool spool offAnalyzing the ResultsAfter cleaning up the output from cellsrv, we can load it into a table in order to run some queriesagainst it. The structure of this table is as follows:SYS:SCRATCH> desc iorm_metricsName Null?
