"conn" field absent for some online devices

[kyl00h]

Hello, I'm trying to establish if certain devices are online/offline by calling certain actions on the websocket.
In particular I noticed that when a device is offline the conn field is absent from the response given by the actions getDeviceDetails and nodes, however there seem to be exceptions to this: there are certain devices that are currently online but still miss this conn field.

Why is that? Is there a more reliable way to establish the connection status of a device, preferably calling an action that returns a list of nodes/devices like getDeviceDetails and nodes do, instead of sending/receiving a message for each device?

can you share an example of what you mean?
and what it should be like so i can check?

i think this must be a bug because every ONLINE device SHOULD have conn as that tells meshcentral that the device is ONLINE
and if the conn is missing, then its OFFLINE

if you can provide access to your server, i could have alook and see if its a bug?
give me a fleemail/disc/whats/tele/sig/etc 👍

Unfortunately I can't provide access to the server right now, it seems to be a bug for me imo too, besides conn makes more sense for it to be 0 instead of completely missing if a device is offline

I have another question, how does the web client establish in the device list page if a device is online or offline (graying out the name and icon)?

no worries, unless you can provide sample FULL outputs of the getDeviceDetails
then i can look into what its giving out and maybe why its missing it

if you ever want to debug what happens etc in the web ui and its control websocket, add ?trace=1 to the url bar
then open up the browsers dev tools, and check the console output
it spits out what gets send and whats received

The ?trace=1 feature is really cool and has been really helpful, thank you

Not too sure yet, but my script did the matches using the device rname, and I found out that there were devices with the same rname, so the issue was probably due to the fact that i was looking at the conn field of a device that was in reality offline but had the same rname of another device that's online, can rname be enforced to be unique somehow (I thought it already was)?

[si458]

The rname and name are different things, if i remember the rnane is the OS NAME, where as name is the name u call it in meshcentral, as remember u can change the machine names in the Web ui to something u remember rather than the OS name

I've found the issue (I've edited my previous answer), thank you for your help
