RE: Autosave -- debug output when field is updated

[Mark Rivers <rivers@cars.uchicago.edu>]

Hi Evan,

 

Note that the rate at which the PV updates and the rate at which the autosave file is written are quite different things.  I don’t think it would use a lot of CPU for the PV to update rapidly when the file is only being written every 30 seconds or so.  But perhaps I am wrong?

Subject: Autosave -- debug output when field is updated

 

Hello,

 

Apologies in advance if this is in the documentation somewhere, I was unable to find it.

We have an IOC which uses quite a lot of CPU when autosave is turned on. This is most likely the result of some inadvertently autosaved fields being updated at 100Hz. Is there a straightforward way, such as an IOC shell command, to print some debug output whenever an autosaved field is written?

 

Best,

Evan
