RTT on gateway status



  • Hi all!

    See screenshot of gateways monitor and actual pfSense ping results.
    Is this OK or not?

    And if it is, somebody care to explain why?

    Thanks!

  • It's not clear what you are asking after. If you are asking about the difference between the average reported by ping and the average shown by the gateway monitor, then it's important to keep in mind that these are averaging over different sample sets. Ping is looking at 10 samples over the 10 seconds you running the command, whereas by default, the gateway monitor is looking at 120 samples over the preceding 30 seconds. It's easy to have a high latency spike that has an extended effect on the 30 second average.



  • Thanks man!
    Exactly what I needed to know and your answer explains it :)
