7.2.3 Setting monitoring intervals

Enter the interval at which performance information is secured in the ETERNUS Disk storage systems and Fibre Channel switch common settings. You can specify 5, 10, 30, 60, 300, or 600 seconds as the interval. However, intervals that can be specified vary depending on device models and the number of Logical Volumes indicating performance level being maintained.

Point

In LAN traffic or cross-subnet (where there is a gateway between the performance monitoring target device and the Management Server) situations, it may not be possible to obtain the performance information inside the monitoring interval that was set. Please change the monitoring interval when you cannot acquire performance information on each monitoring interval.

Note

  • The Fibre Channel switch and Fibre Channel switch blade as shown in the table below, set a monitoring interval according to the FC transfer rate. If this setting is incorrect, it might not be possible to obtain the correct performance value from the device.

  • On the performance information for the number of active disks, power consumption and temperature, the performance monitoring interval sets 60 seconds if its interval is set to shorter than 60 seconds.

Since the performance management unit is started as a daemon of the Management Server, the unit continues obtaining performance information while the Management Server is active, without starting the Web Console.

The logical configuration of the storage device is recognized, and the obtaining of performance information starts. At the start of obtaining performance information of the selected storage system, an amount of time (tens of seconds to several minutes) is spent to obtain the logical configuration before any performance information is actually obtained.
