How to check if push server is online?

[luX0r-reload]

Hello,
thanks for your nice works!
I'm using your push server sample code and it works fine.
I need to send data to push server only if push server is up and running.

$context = new ZMQContext();
$socket = $context->getSocket(ZMQ::SOCKET_PUSH, 'my pusher');
$socket->connect("tcp://localhost:5555");
$socket->send(json_encode($entryData)); /* run this line only if socket is up and running */

How I can do it?

Thanks in advance

L.

@luX0r-reload Do you still need this information if you are switching off of ZMQ? (ratchetphp/Pawl#70)

I'm not switching. My hosting provider installed ZMQ on VPS and all works fine now.
So... yes, If possible I need this information for secure my application.

@luX0r-reload If you need to detect when the websocket server is up, consider connecting with a websocket client library.

Hi, i have the same problem. Websockets with pusher works fine but i would like to know if server is up when i cast: "$socket->send(json_encode($entryData))".

SEND always return an empty ZMQSocket Object.

Message stays in queue and were received when server runs.

If i convert it into a non persistent with: "$context = new ZMQContext(1, false);", then SEND returns same result but the page remains blocked until server is up and running.

Is there a way to know if the message sent is in queue or it's sent succesfully?

I have tried this: "$socket->send(json_encode($entryData),ZMQ::MODE_DONTWAIT)" but same result.

Thank you.
