PVEAPI: rrddata replies sometimes with time only

[devzero]

Hi,

I am querying the rrddata for a specific vm:


"https://$APINODE:8006/api2/json/nodes/$TARGETNODE/qemu/122/rrddata?timeframe=hour&cf=MAX" |jq


generally it works fine, however sometimes it ends with a single time response in the whole array:

    {
      "disk": 0,
      "maxmem": 2147483648,
      "maxcpu": 1,
      "diskread": 0,
      "maxdisk": 34359738368,
      "netout": 0,
      "mem": 1219237106,
      "netin": 0,
      "time": 1754050980,
      "diskwrite": 0,
      "cpu": 0.0125752520266843
    },
    {
      "diskread": 0,
      "maxcpu": 1,
      "maxmem": 2147483648,
      "disk": 0,
      "netin": 0,
      "mem": 1219237106,
      "cpu": 0.0126159918156209,
      "diskwrite": 0,
      "time": 1754051040,
      "netout": 0,
      "maxdisk": 34359738368
    },
    {
      "time": 1754051100
    }
  ]
}

What is the reason why this happens? I tried to find a relation to it, but it seems completely random, however if it happens it is always the last one.

thanks Martin
