Function: performPortCheckWithRetry()

function performPortCheckWithRetry(
    host: string,
    port: number,
    timeout: number,
    maxRetries: number,
    signal?: AbortSignal
): Promise<MonitorCheckResult>;

Defined in: electron/services/monitoring/utils/portRetry.ts:81

Performs a TCP port connectivity check with retry logic and exponential backoff.

Parameters​

host​

string

Target hostname or IP address to check.

port​

number

Port number to test connectivity.

timeout​

number

Maximum time to wait for each connection attempt in milliseconds.

maxRetries​

number

Number of additional retry attempts after initial failure (0 = try once only).

signal?​

AbortSignal

Returns​

Promise<MonitorCheckResult>

A promise that resolves to a MonitorCheckResult containing port details, response time, and status. If all attempts fail, the result is a standardized error result.

Remarks​

This function wraps performSinglePortCheck with retry logic using withOperationalHooks. It attempts to connect to the specified host and port, retrying on failure up to maxRetries times (for a total of maxRetries + 1 attempts). Exponential backoff is applied between attempts. Debug logging is enabled in development mode. If all attempts fail, a standardized error result is returned via handlePortCheckError.

Example​

// Try once, no retries
const result = await performPortCheckWithRetry("example.com", 80, 5000, 0);

// Try 4 times total (1 initial + 3 retries)
const result = await performPortCheckWithRetry("example.com", 443, 3000, 3);
