I disagree with the proposed change to scale the HV current for a "nice" display. If values are scaled, the axis should be
scaled in the same way. Otherwise people might read the current from the plot, look at the axis, and again get the wrong
value (the factor of 25x you mention). Sure you can hover with the cursor over the graph, and see the right value, but think

One addition I would be in favour of is to remove the "Order" and replace it with drag&drop handles, because this is what people are more
used to today. Only the old guys like us remember the /etc/init.d/xx_yy scheme where one uses an integer number in the file name to
determine an order.

To limit the impact of the numerous crashes of mhttpd, I installed the monit tool at MEG at PSI
(https://en.wikipedia.org/wiki/Monit). It monitors mhttpd, and if it cannot connect to it for a certain
time, it kills the process and restarts it. This covers endless loops, simple crashes (caused by the

11 Oct 2021, Stefan Ritt, Info, Modification in the history logging system
|
A requested change in the history logging system has been made today. Previously, history values were
logged with a maximum frequency (usually once per second) but also with a minimum frequency, meaning
that values were logged for example every 60 seconds, even if they did not change. This causes a problem.

The short term solution would be to increase the logger timeout in the ODB under
