Performance Observations

Performance Observations

1. Function Overview

This product provides a mechanism for constantly observing the system’s performance.
An overview of the function is given below.

This product constantly observes the following three types of data.

  1. Resource usage amount: CPU and memory usage amount

  2. Traffic volume: The volume of communication port bandwidth used (transmission/reception)

  3. Power consumption: Estimated based on the link speed, PoE power supply level, and fan RPM

Based on the results of observation, one year’s worth of the following change data is accumulated inside this product.

  • Hourly change: Change for each hour (e.g. 0:00, 1:00, ...)

  • Daily change: Change for each day of each month (e.g. 1/1, 1/2, ...)

  • Weekly change: Change for each day of the week (e.g. SUN, MON, ...)

  • Monthly change: Change for each month (e.g. Jan, Feb, ...)

The accumulated data can be backed up to an SD card. *
By accessing this product via the Web GUI, the maintenance personnel can view the various types of change data including live data in the dashboard, and can also acquire the accumulated result in a PC.
Since the acquired data is in *CSV format
, it can also be manipulated using spreadsheet software on a PC.
Maintenance personnel can use this functionality for the following purposes.

  • Determine the short-term communication status

  • Predict long-term network equipment demand

  • Notice wasteful power consumption by determining current power consumption levels

3. Function Details

3.1. Resource and traffic usage observation

Starting immediately after boot, this device automatically observes the CPU and memory and the transmit/receive throughput of each port every second. *
The observed data is *normalized using a moving average
, and one year of data is saved in RAM.

3.2. Observation data backup

Backup of observation data can be specified only in the Web GUI.
Backup of observation data assumes that an SD card is inserted in this device.
If backup is enabled, the most recent hour of observation data every hour starting at the point it was enabled (e.g., 1:00, 2:00 ...) is saved on the SD card.
The saved data is dedicated binary data of this device.
The save-destination on the SD card and the file name of the backup data file are as follows.
