15.5.2 TPC for Disk
TPC for Disk, formerly known as MDM Performance Manager, provides the following
functions:
Collect performance data from devices.
Configure performance thresholds.
Monitor performance metrics across storage subsystems from a single console.
Receive timely alerts to enable event action based on customer policies.
View performance data from the performance manager database.
Enable storage optimization through identification of the best performing volumes.
TPC for Disk collects data from IBM or non-IBM networked storage devices that implement
SMI-S. A performance collection task collects performance data from one or more storage
groups of one device type. It has individual start and stop times, and a sampling frequency.
The sampled data is stored in DB2 database tables.
You can use TPC for Disk to set performance thresholds for each device type. Setting
thresholds for certain criteria enables TPC for Disk to notify you when a certain threshold has
been exceeded, so that you can take action before a critical event occurs. You can also
specify actions to be taken automatically. These may be just to log the occurrence or to trigger
an event. The settings can vary by individual device.
You can view performance data from the performance manager database in both graphical
and tabular forms. This is shown in Figure 15-4.
