• Connection count is displayed on homepage but on listing page they are always 0

Im working against nats-streaming server , Can't see the subject name on "Connections" table under "Subs List" column clearly,
Instead i see 3 subjects with prefix of : INBOX or STAN .
Ex:
_INBOX.CjRaiQ9Kn5sKhGTJyeuDyb,
_STAN.acks.CjRaiQ9Kn5sKhGTJyeuE91,
_INBOX.CjRaiQ9Kn5sKhGTJyeuEEE

Why is that ?

Is this something you'd be interested in having in this tool? Looks to me that this is a very interesting tool for monitoring but any large nats user will probably be using clusters.

In app.js, you could replace
content += '' + val.lang + ' / ' + val.version + '';
by
content += '' + val.name + '';

This could give a better client description with the name give on the client side.

This happens when you have removed all subscriptions before closing the connection.
Fix on app.js :
content += '' + val.subscriptions_list.join(', ') + '';
content += '' + val.subscriptions_list + '';

Fatih, first thanks for the dashboard, its very useful.

I'm not sure if your still developing against it, if you are would you consider adding support for visualizing the payload size? In our application the payloads can be variable based on the underlying components that were interacting with. It would be great to see the message payloads size to understand if we are getting close to the max_payload config setting, possibly as a graph in the dashboard?

Thanks,
Damian.

Would it be possible for this project to have a running log showing where a request has originated from and where it intends to go?

Example

ms1 subscribes to mstopic
ms2 subscribes to mstopic
ms3 subscribes to mstopic
ms1 publishes message to mstopic
ms2 retrieves message from mstopic
natsboard shows that a message was published by ms1 to mstopic and was retrieved by ms2

I have two apps: message generator and consumer.
I run this apps and don't see any connections in connections tab, but on dashboard tab I see two connections, messages tik and all other stuff. When I shutdown message generator the consumer appears on connections tab.

Would be great to have a Dockerfile for easy deployments! I want to try out the monitor but don't wanna setup a node env locally.

When overriding NODE_PORTWS on the command line, the client part is still trying to connect on NODE_PORT+1.

Please, add auto-update in connections tab like in nats-top

How can we secure access to nats dashboard?
