> [@Monitoring upgrade](https://community.ntppool.org/t/monitoring-upgrade/2770/17): > > Yeah, your server appears to do so well in the monitoring that it’s breaking the graph! 😃 May be the opposite, when there is high offset value (one sample enough)? Let’s compare the two graphs: ![image](https://us1.discourse-cdn.com/flex016/uploads/ntppool/original/2X/6/62cfc3beeb31b9a69007f31428293f411cfa597a.png) ![image](https://us1.discourse-cdn.com/flex016/uploads/ntppool/original/2X/1/148b1e1a2ccbf586267c56aa647f53eb87159cfd.png) The two servers are very similar. On the second image where the left side Y scaling is incorrect, the green dots are denser than on the first image. There is one bad offset sample, a red dot on the botom right side directly siting on the X axis. So the correct reading of the left Y axis would be: 0 ms, -100 ms, -200 ms … -700 ms. ---

Yeah, I saw you pointed that out in the other thread and updated [the GitHub issue](https://github.com/abh/ntppool/issues/223). 🙂
