MP blades
The following table shows the file names and types of information in the Monitor Performance
window that can be exported to files using the Export Tool. The file contains statistics about usage
rates of MPs.
Table 18 MP usage rate of each resource allocated to MP blades
Data saved in the file CSV file ZIP file
The MP usage rate of each resource allocated to MP blades in short range
is output in the following formats: PHY_MPPK_x.y.csv PhyMPPK_dat.ZIP

Performance information of LDEVs
Kernel-type *;LDEV;LDEV-number;Usage-rate
• Performance information of journals
Kernel-type *;JNLG; Journal-number;Usage-rates
• Performance information of external volumes
Kernel-type *;ExG;External-volume-group-number;Usage-rate
You can view up to 100 of the most used items in order of use.
Caution: Use performance information as a guide to identify resources
that greatly increase the MP usage rate. Adding the performance items
together does not equal the total estimated capacity of the MPs. Likewise,
this performance information is not appropriate to estimate the usage of
a particular resource.
* The kernel type is any one of the following types:
Open-Target, Open-Initiator, Open-External, MF-Target, MF-External, BackEnd, or System.
Remote copy operations by Cnt Ac-S/Cnt Ac-S Z (whole volumes)
The following table shows the file names and types of information on the Usage Monitor tab in the
Cnt Ac-S and Cnt Ac-S Z window that can be exported to files using the Export Tool. These files
contain statistics about remote copy operations (whole volumes) by Continuous Access Synchronous
and Continuous Access Synchronous Z.
