record-interval

Function

The record-interval command sets the number of performance statistics collection cycles after which the system generates a statistics file.

The undo record-interval command restores the default number of performance statistics collection cycles.

By default:

If a short performance statistics collection cycle (5, 10, 15, 30, or 60 minutes) is set, the system generates a statistics file after four cycles.
If a long performance statistics collection cycle (1440 minutes) is set, the system generates a statistics file after one cycle.

Format

Parameters

Parameter	Description	Value
interval	Specifies the number of performance statistics collection cycles.	The value is an integer.

Usage Guidelines

Usage Scenario

After you configure a performance statistics collection task, the system periodically saves collected performance data to statistics files. To set the interval at which the system generates statistics files, run the record-interval command. Then the system generates performance statistics files every cycle x interval minutes, and automatically saves the performance data in the files. The system generates a maximum of four statistics files for each performance statistics collection task, and saves performance statistics files to the path flash: /pmdata by default.

Prerequisites

The performance statistics function has been enabled using the statistics enable command.
The cycle has been set using the statistics-cycle command.

Example

# Configure the system to save performance data to a statistics file every three performance statistics collection cycles. If the performance statistics collection cycle is 5 minutes, the system saves a performance data to a statistics file every 15 minutes.
