<MonitorCheckResult
>
Defined in: electron/services/monitoring/utils/portRetry.ts:78
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).
Returns
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);
