Hi, does the PHP API Version a PING Function has included? I know the PING Function from Solar, its to check if the server is available and if not you can make a Fallback. Or how is the best way to check if the elasticsearch server is reachable?

Stefan, If the TransportClient or NodeClient is set up as needed, then you can easily wait for the cluster to be ready to use and let Elasticsearch do the per-server discovery itself. At a high level (assuming this is part of some class that includes private Client client;). Error reporting is minimal; that can be easily adjusted depending on your needs: public void waitForYellowStatus(TimeValue timeout, boolean waitForNode) throws MyException { long startTime = System.currentTimeMillis(); TimeValue sleepTime = new TimeValue(2000); for (;😉 { try { client.admin().cluster().prepareHealth().setTimeout(timeout) .setWaitForYellowStatus().execute().actionGet(); return; } catch (NoNodeAvailableException e) { if ((!waitForNode) || ((System.currentTimeMillis() - startTime) \> timeout.getMillis())) throw new MyException("Cluster is not available: " + e); sleep(sleepTime); } catch (ElasticsearchException e) { throw new MyException("Cluster is not ready: " + e); } } } Anyway, this works well for me. Hope it helps you! Brian -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Just issue a HTTP HEAD request against port 9200 of the host you want to connect to and check for status 200 curl -I -XHEAD localhost:9200 HTTP/1.1 200 OK Content-Type: text/plain; charset=UTF-8 Content-Length: 0 Or, if you want version information, use a HTTP GET request curl -XGET localhost:9200 { "status" : 200, "name" : "Human Fly", "version" : { "number" : "1.1.0", "build\_hash" : "2181e113dea80b4a9e31e58e9686658a2d46e363", "build\_timestamp" : "2014-03-25T15:59:51Z", "build\_snapshot" : false, "lucene\_version" : "4.7" }, "tagline" : "You Know, for Search" } Jörg On Wed, Apr 23, 2014 at 5:47 PM, Stefan Kruse [info@all-around-shipping.de](mailto:info@all-around-shipping.de)wrote: > Hi, does the PHP API Version a PING Function has included?
