    retry_times: 10,
});

// Create a LogGroup instance
let logGroup = new LogGroup();
logGroup.setSource("1.XX.XX.XX"); // Replace with your IP address

// Create a Log instance
let log = new Log(Date.now());
log.addContent("hello", "hello world1");
log.addContent("world", "hello world2");

// Add Log to LogGroup
logGroup.addLog(log);

// Create a PutLogsRequest instance
let request = new PutLogsRequest("8bbfXXXXXXXXXXXXXXXXXXXXXXXXXXXXX", logGroup); // replace with your log topic ID

// Upload logs
async function uploadLogs() {
    try {
        let data = await client.PutLogs(request);
        console.log("Logs uploaded successfully:", data);
    } catch (error) {
        console.error("Error uploading logs:", error);
    }
}

// Call the log upload function
uploadLogs();
