Hi Vladimir,
It's exactly as you were citing from the Release Notes:
EPICS Base itself does not provide this ability, but only the hook
needed by such a facility.
This new hook facility is described in more detail in the 3.14
Application Developer's Guide, in chapter 8.8 ("Trapping Channel Access
Writes").
Documentation on the DESY "CA Put Logging" module, which can be hooked
into this facility, can be found on the DESY page that can be reached
from the "Extensions" page of the EPICS Web (section "Other Tools or
Libraries").
There are no plans to include such plug-in modules into EPICS Base.
Hope this helps,
Ralph

Hi,
Can anyone answer the following
question: is mechanism to log ca write activity implemented in 3.14
base epics release? According to documentation, it is supposed to
( http://www.aps.anl.gov/asd/controls/epics/EpicsDocumentation/ReleaseNotes/ReleaseNotes3.13.4.html :
"The purpose of
this new facility is to allow things like logging Channel Access
writes. Epics base itself does not provide this ability but only the
hook needed by such a facility. DESY has developed a facility that logs
CA puts. The trap writes feacure allows the DESY facility to be
implemented without any changes to epics base. In addition it allows
the user to decide what should be logged. This new facility will be
described in more detail in the 3.14 version of the Application
Developer's Guide."
but if I just look for the presence
of environmental name EPICS_IOC_CA_PUT_LOG_INET or as was suggested by
V.Korobov name which is supposed to be used in later CA_PUT release:
EPICS_IOC_LOG_CONFIG_FILE_NAME, then both are missing in src directory
of the epics base 3.14.6
Does anyone use such tools? And how?
Thanks,
Vladimir
