VNA Fortimanager plugin load

Issue/Introduction

As we need to add a fortimanager plugin to our VNA environment, the customer wants to know what load this will give on their environment.

They fear the VNA API requests might overload the fortimanager, or even worse, the API request cascade to the end devices overloading these devices.

 

Please confirm
enabling the plugin will not overload the fortimanager?
API requests are limited to the fortimanager only and do not trigger API requests to the end devices?

 

Environment

23.3.x 24.3.x

Cause

Questions on the load and api calls.

Resolution

API requests are limited to the fortimanager only and do not trigger API requests to the end devices?

Answer)
Plugin will connect to the fortimanager only to collect the data

 

Enabling the plugin will not overload the fortimanager?

Answer)
The load is contingent upon the live environment; therefore, a thorough evaluation is necessary.
To potentially mitigate the load, you might consider increasing the poll rate within the plugin configuration.

Example:

Default:
"INVENTORY_POLL_RATE": "0 */15 *"
"PERFORMANCE_POLL_RATE": "0 */5 *",

Suggested:
"INVENTORY_POLL_RATE": "0 */60 *",
"PERFORMANCE_POLL_RATE": "0 */20 *",

Based on the system stability you can decrease as per your environment
