NOTE: HP recommends that you not use the remote logging feature for array performance logging. The HP P6000 Performance Data Collector client and server should be running on the same system to gather logging for performance and state data.

Configuration recommendations
HP recommends the following maximum configuration for HP P6000 Performance Data Collector:
•A maximum of 20 concurrent connections to the HP P6000 Performance Data Collector service, where a connection is a successful communication channel that can be established between the client and the HP P6000 Performance Data Collectorserver.
•A maximum of 16 arrays.
•A maximum active I/O on approximately 4,000 virtual disks in parallel across the 16 arrays.
•The polling interval for the HP P6000 Performance Data Collector service set to 60 seconds.
Connecting to HP P6000 Performance Data Collector remotely
Use the evaperf server command to configure the HP P6000 Performance Data Collector CLI to communicate with a remote HP P6000 Performance Data Collector service:
evaperf server host port [username] [-usessl]
where:
host | is the hostname or IP address of the server running the HP P6000 Performance Data Collector |
| service. |
port | is the TCP port from which the HP P6000 Performance Data Collector data collection service will |
| receive an RPC request (default is 860). |
