Performance Data Report by the FW

This section describes the mechanism for the FW to report performance data to the cloud management platform.

After the cloud management platform brings the FW under its management, it acquires operation performance data of the FW as required. The cloud management platform delivers a performance data collection instruction to the FW. The FW collects performance data and reports the data to the platform accordingly. The detailed process is as follows:

Figure 1 Basic process for the FW to report performance data to the cloud management platform

The cloud management platform sends a performance data collection instruction to the FW through the NETONF channel.
The instruction specifies such fields as the type of data to be collected and collection period. The collectable performance data includes the device performance data, interface performance data, and device data. The performance data contains data of subtypes. For details, see Table 1.
The FW collects performance data as specified in the instruction.
The FW caches the collected performance data to the data buffer.
The data buffer submits the data to the data assembly module of the FW when the following two conditions are met:
- The buffer has over 5 KB performance data.
- The duration for which the performance data is kept in the buffer has exceeded the specified value.
If either condition is met, performance data in the buffer is submitted to the data assembly module of the FW.
The data assembly module reassembles performance data sent from the data buffer and sends the reassembled data to the cloud management platform through the HTTP2.0 channel.
The structure of the performance data collected by the FW varies with the data type. The data assembly module processes data of various types into a unified format for the data to be transmitted through the HTTP2.0 channel
