Connect to host error using php client - any ideas?


(Rsmarshall) #1

At what seems like random intervals I am seeing the following error in my application logs:

RROR: exception 'Elasticsearch\Common\Exceptions\Curl\CouldNotConnectToHost' with message 'couldn't connect to host'

It's in vendor/elasticsearch/elasticsearch/src/Elasticsearch/Connections/AbstractConnection.php:320.

I can't find anything else in the logs, so any pointers on where to look for the problem are greatly appreciated.

php version info:

PHP 5.3.10-1ubuntu3.18 with Suhosin-Patch (cli) (built: Apr 17 2015 15:11:25)
Copyright (c) 1997-2012 The PHP Group

I know it's an old version, old server we are trying to get the client to ok the upgrade. It's Ubuntu 12.04 LTS, Elastic search client v1.3.4

The search method is"

/**
 * Returns an array of products IDs for products matching the search query
 *
 * @param string $query
 * @return array
 */
public function search($query)
{
    if (is_numeric($query)) {
        $return = $this->_client->search(
            array(
                'index' => self::INDEX,
                'type'  => self::TYPE,
                'body'  => array(
                    'query' => array(
                        'multi_match' => array(
                            'query'  => $query,
                            'fields' => array('id', 'barcodes'),
                        ),
                    ),
                    'size' => '5000',
                ),
            )
        );
    } else {
        $search = array(
            'index' => self::INDEX,
            'type'  => self::TYPE,
        );

        $words = explode(' ', $query);
        foreach ($words AS $word) {
            $search['body']['query']['bool']['must'][] = array('wildcard' => array(
                    '_all' => array(
                        'value' => $word.'*',
                    ),
                )
            );
        }

        $search['body']['size'] = 5000;

        $return = $this->_client->search($search);
            
    } 

    $productIds = array();

    if (!empty($return['hits']['hits'])) {
        foreach ($return['hits']['hits'] as $hit) {
            $productIds[] = $hit['_id'];
        }
    }

    return $productIds;
}

In the elasticlog file all I have is:

About 15 mins after a restart my cluster health is:

{"cluster_name":"elasticsearch","status":"yellow","timed_out":false,"number_of_nodes":1,"number_of_data_nodes":1,"active_primary_shards":5,"active_shards":5,"relocating_shards":0,"initializing_shards":0,"unassigned_shards":5}

Thanks
