I have multiple child nodes streaming to a parent node. So it is essentials to know which child triggered the alert. But its seems I do not have any useful variables to use in info or summary message.

template: vps_down
      on: netdata.streaming_inbound
    lookup: average -10s of stale disconnected
   units: nodes
   every: 10s
    warn: $this > 0
   delay: up 10s down 1m
    info: A permanent VPS has disconnected from the parent
      to: sysadmin

I see that the chart supports only these lables:

        "labels":["time","local","virtual","loading","stale archived","stale disconnected","waiting","waiting replication","replicating","running"],
        "data":[
            [1768216649,1,0,0,0,0,0,0,0,1],

So is there no way for me to know which node got disconnected/reconnected and triggered the alert?
The default streaming_disconnected alert also doesn't tell which node was disconnected.

The notification subject/heading metions hostname of the parent node:
parent needs attention, parent recovered
