Measure ESP32 CPU Utilization - cpu-usage

Question

I am communicating two ESP32 boards which are connected to a Wifi Network. One ESP32 board is the Server and the other is the client. I want to measure the ESP32 CPU utlization on the client ESP32. I have no idea how to do it and have not yet found any useful resources on the internet. Can someone help me with this?
This is the code on server
#include <WiFi.h>
#include <ESPAsyncWebServer.h>
const char* ssid = "XXXXX";
const char* password = "XXXX";
AsyncWebServer server(80);
void setup() {
Serial.begin(115200);
WiFi.begin(ssid,password);
while (WiFi.status()!= WL_CONNECTED){
delay(200);
Serial.println("Connecting to Wifi...");
}
Serial.println("Connected to Wifi");
Serial.println(WiFi.localIP());
server.on("/test", HTTP_GET, [](AsyncWebServerRequest *request){
Serial.println("Request received from esp32client");
request->send(200, "text/plain", "Hello from ESP32Server to ESP32Client");
});
server.on("/test1", HTTP_GET, [](AsyncWebServerRequest *request){
Serial.println("Request received from PC-Client");
request->send(300, "text/plain", "Hello from ESP32Server to PC");
});
server.begin();
}
void loop() {
// put your main code here, to run repeatedly:
}
This is the code on Client
#include <WiFi.h>
#include <HTTPClient.h>
const char* ssid = "XXXXX";
const char* password ="XXXXX";
void setup() {
Serial.begin(115200);
WiFi.begin(ssid,password);
while (WiFi.status()!= WL_CONNECTED){
delay(500);
Serial.println("Connecting to Wifi...");
}
Serial.println("Connected to Wifi Network...");
Serial.println(WiFi.localIP());
}
void loop() {
HTTPClient http;
http.begin("http://192.168.43.35/test");
int httpCode = http.GET();
if (httpCode > 0) {
String payload = http.getString();
Serial.println(httpCode);
Serial.println(payload);
}
else {
Serial.println("Error on HTTP request");
}
http.end();
delay(30000);
}

Use this function to get CPU load
vTaskGetRunTimeStats(char *buffer);
It tells CPU utilization by currently running task on esp32.
API documentation here.
