|
we had a bit of trouble with open network ports recently and I now think security of MIDAS RPC
ports needs to be tightened.

One thing coming to my mind is the interface binding. If you have a midas host with two networks
("global" and "local"=192.168.x.x), you can tell to which interface a socket should bind.
By default it binds both interfaces, but we could restrict the socket only to bind to the local

We finished running the DarkLight experiment and I am reporting accumulated bugs that we have run into.
1) history plots on 12 hrs, 24 hrs tend to hang with "page not responsive". most plots have 16-20 variables,

Now I had a similar case that the browser froze when showing 24h of data. Tuned out that 80k points are a bit much. I changed the code so that it starts
binning when showing 8h or more. This is not a perfect solution. The code should check at which interval data is written, then
automatically start binning when approaching 4000 points or more. That would however require more complicated code, so I leave it as it is right now. Feedback |

> BTW, it looks like we are parsing the whole JSON ODB dump (200k+) on every odbxx access. Can you parse it just once?
You are right. I changed the code so that the dump is only parsed once. Please give it a try.
