This panel contains all automatic refresh options. The principle is all the same, check the box if you want to enable the auto refresh and choose a time between 1 and 999. You can find below a more thorough explanation of some of the options.
Rotating server banner
This option will send a message to the client that a new banner is available to be displayed. Some clients do not display banner and this will only generate unnecessary traffic. On client who display banners a low value will cause the client to stop displaying banners after a few message. I would suggest to put this value at around 30 minutes if you want to use such feature.
All automatic refresh option
There are various automatic refresh options, which will cause the server to refresh the panel at various time intervals. The time interval should be chosen as prime number but is not necessary. The time interval should also be reasonable, for example if the file statistics panel takes about 4 minutes to refresh then the time interval should be greater than 4 minutes. I find value around 30+ minutes and 5+ seconds for the file statistic refresh to work well.
