CakePHP : Monolog package throw runtime exception and application stop working - php

Question

composer.json packages as below,
"monolog/monolog": "~1.25.4",
"newrelic/monolog-enricher": "^1.0",
Below file is throwing run time exception,
vendor/monolog/monolog/src/Monolog/Handler/Curl/Util.php
<?php
namespace Monolog\Handler\Curl;
class Util
{
private static $retriableErrorCodes = array(
CURLE_COULDNT_RESOLVE_HOST,
CURLE_COULDNT_CONNECT,
CURLE_HTTP_NOT_FOUND,
CURLE_READ_ERROR,
CURLE_OPERATION_TIMEOUTED,
CURLE_HTTP_POST_ERROR,
CURLE_SSL_CONNECT_ERROR,
);
/**
* Executes a CURL request with optional retries and exception on failure
*
* #param resource $ch curl handler
* #throws \RuntimeException
*/
public static function execute($ch, $retries = 5, $closeAfterDone = true)
{
while ($retries--) {
if (curl_exec($ch) === false) {
$curlErrno = curl_errno($ch);
if (false === in_array($curlErrno, self::$retriableErrorCodes, true) || !$retries) {
$curlError = curl_error($ch);
if ($closeAfterDone) {
curl_close($ch);
}
throw new \RuntimeException(sprintf('Curl error (code %s): %s', $curlErrno, $curlError));
}
continue;
}
if ($closeAfterDone) {
curl_close($ch);
}
break;
}
}
}
if a runtime error occurs, we don't want to stop application execution to add a log.
How can I handle such a situation?
I tried to overwrite class vendor/monolog/monolog/src/Monolog/Handler/Curl/Util.php
add the below code in the composer.json file
"autoload": {
"psr-4": {
"Monolog\\Handler\\Curl\\" : "lib/MonologCurl",
}
}
created the same Util.php class in lib/MonologCurl directory to use modified code
and run composer dump-autoload
it is throwing an error as below
Fatal error: Uncaught Error: Class 'Monolog\Handler\Curl\Util' not found in /test/instances/fd/local/vendor/newrelic/monolog-enricher/src/Handler.php:138 Stack trace: #0 /test/instances/fd/local/vendor/newrelic/monolog-enricher/src/api1/Handler.php(53): NewRelic\Monolog\Enricher\AbstractHandler->sendBatch('[{"message":"St...') #1 /test/instances/fd/local/vendor/monolog/monolog/src/Monolog/Handler/BufferHandler.php(92): NewRelic\Monolog\Enricher\Handler->handleBatch(Array) #2 /test/instances/fd/local/vendor/monolog/monolog/src/Monolog/Handler/BufferHandler.php(108): Monolog\Handler\BufferHandler->flush() #3 [internal function]: Monolog\Handler\BufferHandler->close() #4 {main} thrown in /test/instances/fd/local/vendor/newrelic/monolog-enricher/src/Handler.php on line 138
what should be best solution?
