Controlling the performance collector
The following table describes the system parameters that control the performance collector:
Parameter | Description | Default |
|---|---|---|
SGP_MAXDSNS | Specifies the maximum number of data sets that could be referenced during a recording interval duration | 1000 |
SGP_MAXVOLS | Specifies the maximum number of volumes that could be referenced during a recording interval duration | 250 |
SGP_MAXJOBS | Specifies the maximum number of jobs that could be referenced during a recording interval duration | 200 |
SGP_MAXSCLS | Specifies the maximum number of storage classes that could be referenced during a recording interval duration | 100 |
SGP_MAXPOLS | Specifies the maximum number of pools that could be referenced during a recording interval duration | 100 |
SGP_MAXPTHS | Specifies the maximum number of channel paths that could be referenced during a recording interval duration | 256 |
SGP_MAXLCUS2 | Specifies the maximum number of logical control units that could be referenced during a recording interval duration If the value is set too low, the system does not set aside enough buffer space to handle all of the records. You must determine a value that provides enough buffer space for LCU records without causing a shortage of dataspace storage for other records. | 256 |
SGP_MAXCCUS | Specifies the maximum number of cache control units that could be referenced during a recording interval duration | 256 |
SGP_MAXDIRS | Specifies the maximum number of RAID EMC directors that could be referenced during a recording interval duration | 256 |
SGP_MAXPVLS | Specifies the maximum number of RAID EMC physical volumes that could be referenced during a recording interval duration | 250 |
START_SGP | Indicates whether to prevent the automatic startup of the performance collector | Y |
