These components are applicable only when the server and client are installed together. When installed individually, the contents of the directory vary, based on the component installed.

IMPORTANT: When a controller reboots, the connection between the client to the server must be reestablished.

The path failover feature, which provides a mechanism where, upon the failure of one communication path between the HP P6000 Performance Data Collector server and the storage system controller, there is an automatic failover to an alternate path for continued communication with the controller.

HP P6000 Performance Data Collector server side logging of performance and state data

This feature provides the functionality to collect the following data periodically and log it to a data store:

•EVA Performance information

•EVA Configuration and State change information

All of the collected data is organized under a root directory with one subdirectory for each EVA for which data is being collected.

Performance and state logs retrieval from HP P6000 Performance Data Collector client

Historical performance and state change data can be retrieved through the HP P6000 Performance Data Collector CLI.

Displaying historical state changes and performance data

The following command displays performance data and state changes for objects of a specified type within the specified time range. The syntax is:

evaperf hist wwn object_type start_time end_time [object_id], where wwn is the node WWN of the array.

Table 2 (page 71) shows the valid values for object_type and the information displayed in the output of the command.
