eMQ dashboard implementation

[preriasusi]

Let's keep this as a epic. To be splitted into tasks.

[marla-singer]

@preriasusi Will you add a description for the issue?

[preriasusi]

Tomorrow to choose technologies and split into taks

@phanimahesh I've got questions about behaviour of MQTT rules

ACL page

1. The previous version of ACL rules that are available in APInf platform right now it allows to set Allow/Deny options.

Current version of ACL

Future version of ACL

Is it still needed options and they're missed or it will be gone?

2. What fields are required? Based on the existing version of ACL, it supposes that one of three fields (Username, ID, IP) is filled. Is it still so? What fields are required?

MQTT Dashboard How can I fetch data for Incoming/Outgoing Bandwith chart?

[phanimahesh]

The wireframe needs a couple of updates. I'll talk to Illya and get back to you. Regarding bandwidth, I still don't have a eaasy way of extracting it, will let you know once I have it. Expect to have a url returning json, with the bandwidth values in response.

@marla-singer we had a call with @phanimahesh, I will apply discussed changes, confirm them and then add to mockup for implementation.

@phanimahesh I found some problem with "Delivered messages" 🤔

The table "Wildcards" has the column "Delivered messages" then supposes to display a count of delivered messages for a particular topic. But the fetched data from Elasticsearch doesn't contain any field "topic" so I can't associate that with particular topic value. The same stuff is for chart Delivered Messages on the particular Topic view.

Fetched data

"_source" : {
          "client_id" : "mosqsub|4263-frozenlake",
          "event" : "message_delivered",
          "id" : "AAViz+71xm/EsgAABWq/mg==",
          "timestamp" : 1516020090390
        }

Wireframes

What to do? Rethink "Delivered messages" or another thing?

[phanimahesh]

Sorry about that, looks like we weren't including topics in logs. I'll include it and redeploy. It's just a one line config change.

[marla-singer]

1. Charts (1) display data for ALL topics at all or for the starred topics that are shown in the "Starred Wildcards" table below?

2. Table "Starred wildcards". Is data updated every 5 seconds when "Last 24 hour" time frame is selected?

3. When the date range picker is changed to another value then chart data is updated to the related timeframe as well or not?

4. Topics page. Is table data updated every 5 seconds when "Last 24 hour" time frame is selected?

@marla-singer

1. Yes, for all topics, not only starred.
2. No updates needed, just a data for 24 hours, week, month.
3. Chart and table are not connected.
4. Same here, no updates, only data for selected period.

@phanimahesh @ilarimikkonen What do you think about real-time? Is it from 00:00 to right now or something else?

[ilarimikkonen]

@marla-singer @55 on points 1-4 I agree with Illya.

[ilarimikkonen]

about real time, IF i got this right I propose 24 hrs. reasoning being that if you look at the real time stats at 00.01, then you are screwed if it's from 00.00-00.01

[marla-singer]

@55 @ilarimikkonen If "Real time" and "Outgoing Bandwith" are selected then are other values must be updated every 5 seconds as well or not?

[55]

@marla-singer correct. When you click on number (and it gets highlighted) it changes chart, other numbers still have to be updated every 5 sec.

[phanimahesh]

Bandwidth updates every 5 seconds are not currently possible. We calculate bandwidth in a very roundabout way, the actual stats we have access to are the number of packets, and estimates from the monitoring server (nagios/reimann).
