# 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.

- Performance Observations

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 is stored in the ROM of this product.
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 usage, traffic usage, and power consumption observation

Starting immediately after boot, this device automatically observes the CPU, memory, transmit/receive throughput of each port, and power consumption 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

The backup of observation data is automatically saved in ROM of this device.

### 3.3. Observation data export

Observation data can be exported to a computer only via the web GUI.
Data is exported as *multiple CSV files compressed in zip format. *
The structure of the compressed files are given below.
