Hi Timothy - we do actually have an enterprise license and would appreciate more details on how to use those operators. Thanks!
Thank you, Ilya Ganelin -----Original Message----- From: Timothy Farkas [[email protected]<mailto:[email protected]>] Sent: Thursday, September 03, 2015 12:15 AM Eastern Standard Time To: [email protected] Subject: Re: Visualize custom metrics in the dashboard Hi Ilya, I believe the overall approach is correct. Is {"type":"data", "topic":"c1.citadel.latencies", "data":[{"Elapsed":"3987"}, {"Max (30s)":"3987ms"}, {"Avg (30s)":"257.00ms"}, {"Msgs/sec":"48"}]} the JSON that you are seeing output by the PubSubWebsocketOutputOperator? Also is the receiver of the message sending a {"type":"subscribe", "topic":"c1.citadel.latencies"} message? A quick way to debug whether your messages can be sent or received properly is to use Simple Websocket https://chrome.google.com/webstore/detail/simple-websocket-client/pfdhoblngboilpfeibdedpjgfnlcodoo?hl=en -You can use it to connect to ws://your.gateway/pubsub -Then enter {"type":"subscribe", "topic":"c1.citadel.latencies"} -Then enter {"type":"data", "topic":"c1.citadel.latencies", "data":[{"Elapsed":"3987"}, {"Max (30s)":"3987ms"}, {"Avg (30s)":"257.00ms"} This will not echo the result back to you - If you enter {"type":"publish", "topic":"c1.citadel.latencies", "data":[{"Elapsed":"3987"}, {"Max (30s)":"3987ms"}, {"Avg (30s)":"257.00ms"} This will echo the result back to you Note that if you have a fresh connection and you don't send the subscribe message, you will not get the result echoed back to you. There is an easier way. Datatorrent already has operators which serve data to the UI and Widgets which display the data in the UI, but that is in the Enterprise edition. Hope this helps, please keep us posted Tim On Wed, Sep 2, 2015 at 8:17 PM, Ganelin, Ilya <[email protected]> wrote: > Hi Timothy - the idea was to surface our own metrics to the DataTorrent > UI.
