Problem/Question

Suddenly out of nowhere uptime monitoring started to fail on my lxc node.

Example:

root@vps3073748:~# service wings status
● wings.service - Wings Daemon
     Loaded: loaded (/etc/systemd/system/wings.service; enabled; preset: enabled)
     Active: active (running) since Wed 2025-06-11 07:56:40 UTC; 31min ago
   Main PID: 229056 (wings)
      Tasks: 41 (limit: 76931)
     Memory: 165.8M (peak: 452.2M)
        CPU: 29.192s
     CGroup: /system.slice/wings.service
             └─229056 /usr/local/bin/wings --debug

In netdata API it returns

array(6) {
  ["name"]=>
  string(16) "app.wings_uptime"
  ["family"]=>
  string(6) "uptime"
  ["context"]=>
  string(10) "app.uptime"
  ["units"]=>
  string(7) "seconds"
  ["last_updated"]=>
  int(1749630575)
  ["dimensions"]=>
  array(1) {
    ["uptime"]=>
    array(2) {
      ["name"]=>
      string(6) "uptime"
      ["value"]=>
      float(0)
    }
  }
}

In netdata UI it’s not showing uptime for it.

My apps_groups.conf has

wings: *wings*

Relevant docs you followed/actions you took to solve the issue

Environment/Browser/Agent’s version etc

Netdata Agent:
v2.5.0-194-nightly
(Previsously I was using stable channel. tried nightly only now)

What I expected to happen

Uptime to show correct value in API and show in netdata UI

Every other uptime monitoring seem to work. Only this is failing.
I suspect it’s somehow related to lxc. As it’s my only lxc node. Everything else is bare metal.
