    <p>I am using the <a href="https://github.com/adamvr/MQTT.js/" rel="nofollow">node.js mqtt library</a> to connect a internet mqtt service</p> <pre><code>var name = '/#'; var mqttclient = mqtt.createClient(1883, service.getHost(),{username:"" ,password: service.getKey() }); mqttclient.on('connect', function onConnect(){ winston.info('MQTT Connected'.green, '/'+service.getPattern()+name); mqttclient.subscribe('/'+service.getPattern()+name); mqttclient.on('message', handleMessage); }); mqttclient.on('disconnect', onConnect); mqttclient.on('close', onClose); mqttclient.on('error', onError); function onDisconnect(packet){ winston.info('MQTT MONITOR disconnect!'+packet); } function onClose(packet){ winston.info('MQTT MONITOR close!'+packet); } function onError(err){ winston.error('MQTT MONITORerror!'+err); } </code></pre> <p>when my internet connection disconnects or authentication username/password are wrong, mqtt library will emit the close event, as long as mqtt.end(), this event will be continuously triggered.</p> <pre><code>2013-12-07T18:36:53.835Z - info: MQTT MONITOR close!false 2013-12-07T18:36:54.835Z - info: MQTT MONITOR close!false 2013-12-07T18:36:55.832Z - info: MQTT MONITOR close!false 2013-12-07T18:36:56.833Z - info: MQTT MONITOR close!false 2013-12-07T18:36:57.831Z - info: MQTT MONITOR close!false 2013-12-07T18:36:58.847Z - info: MQTT MONITOR close!false 2013-12-07T18:36:59.842Z - info: MQTT MONITOR close!false 2013-12-07T18:37:00.833Z - info: MQTT MONITOR close!false 2013-12-07T18:37:01.832Z - info: MQTT MONITOR close!false 2013-12-07T18:37:02.847Z - info: MQTT MONITOR close!false </code></pre> <p>it seems to me the mqtt close callback can't tell me what kind of error is happening, such as authentication error or host can't reach error.</p> <p>Moreover, I assume there is a reconnect strategy. how can I control this reconnect strategy in mqtt code?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
