When defining the get_lag and get_lag_cache functions with the threshold, I get the above error.
`function get_lag_cache($wpdb) { try { // Create a new Redis instance $redis = new Redis(); $redis->connect('127.0.0.1', 6379); // Adjust host and port as needed
$lag_data = $redis->get($wpdb->lag_cache_key);
if ($lag_data === false || !isset($lag_data['timestamp']) || !isset($lag_data['lag'])) {
return false;
}
if ($wpdb->lag_cache_ttl < time() - $lag_data['timestamp']) {
return false;
}
return $lag_data['lag'];
} catch (Exception $e) {
return false;
}
}
function get_lag($wpdb) { // Query to get the replication lag $results = $wpdb->get_results("SHOW SLAVE STATUS", ARRAY_A); if (isset($results[0]['Seconds_Behind_Master'])) { error_log($results[0]['Seconds_Behind_Master']); return $results[0]['Seconds_Behind_Master']; } else { return false; } }`
@dd32 Can you please help with this issue? I am not able to enable a lag monitor because of these warnings.
