      Hey Guys,
      I am creating a system to monitor our kopano cluster using dashboards. I am wondering about the meaning of the parameter rtt that the kopano-stats --top command prints out. What does it mean/represent?

      Thanks

        @genz ,

        The RTT(Round Trip Time) is the complete time that a request takes to get a response from the server.

        Regards Robin,

          hey @robing,
          I am monitoring the RTT value given by the kopano-stats script:

          0_1542890608202_a9dbd24e-7b94-4a16-b791-7a6315b54328-image.png

          • Our cluster has been up for 6 weeks and 3 days.
          • The avarage RTT value is: 11.5 ms
          • The highest RTT value we registered is: 3 795 ms

          To sum up: sometimes we see several spikes in the RTT value. These spikes can reach very high values. We do not have any clue about why this is happening.

          My questions are:

          • Is this normal?
          • Is a behaviour you would excpect or we need to change something in our setup?

          Thanks
