Release Notes for iocStats
--------------------------
iocStats-R3-1-14: Apr 29, 2015
* Change to vxWorks osdFdUsage.c to not check the first 3 FDs by Scott Baily:
Unfortunately, the first 3 file descriptors on vxWorks are special
(standard in, standard out, and standard error). The pointers in
iosFdTable have the value FFFFFFFF. For 6.6 and above the reference
count isn't checked so there's no problem. But some of our systems use
6.3 and this code causes reads from page 0 of RAM.
* Change to add process ID and parent process ID records.
* Change to use github.
* Change to perform most statistics in a thread separate from record
processing.
iocStats-R3-1-13: July 13, 2014
* Bug fix in update period AO record initialization.
iocStats-R3-1-12: June 19, 2014
* Change by Eric Bjorklund:
Change devIocStatsGetClusterInfo(). The fundamental problem is that
vxWorks -- at least ours (6.8) -- does not fill in all of the entries
in the cluster table. In our example, only 8 of the 13 allocated table
entries are filled in, and when devIocStatsGetClusterInfo() tries to
process the 9th it gets a page fault exception from the null pointer.
* Change by Tim Mooney:
Add caQtDM displays, translated from the .adl files using caQtDM 3.7.8.
* Change by Stephanie Allison:
Added waveform support for epics version, startup script,
application directory, and bootline.
* Changes by Ben Franksen and Ralph Lange:
- Scan rates now floating point instead of integer.
- we have recently discovered some bugs in devIocStats in the vxWorks
implementation that measures the cpu load, which result in wrong
results to be displayed. I hacked away at the problem for some days
and ended up with a complete re-write. The solution considerably
reduces code size and complexity, is therefore much easier to
understand and maintain, and --most importantly--
works correctly. It also contains some additional features:
* A test procedure that measures how well the initial calibration
works by doing it for a number of times and gathering statistics
(min, max, avg). This was useful to determine how long initial
calibration should run (the default is 30 clock ticks which on a
mv2100 gives me a variation of less than 0.4%).
* Another test procedure (to be called from the shell) adds exactly
50% load to the IOC (it burns cpu for one clock tick, then sleeps
for one, and repeats that in a loop for the given duration), so one
can see whether the measured cpu load increases appropriately
(it does on my test machines).
* Experienced users can customize behaviour to a certain extent by
changing the values of some global variables.
* I moved the cpuBurnLoad50 test routine to a separate file, since
it is independent of the new implementation of osdCpuUsage; it gets
compiled to a stand-alone object file which you must link to your
IOC binary if you want to use it, e.g.
TESTIOC_OBJS_vxWorks += $(IOCSTATS_BIN)/osdCpuUsageTest.o
iocStats-R3-1-11: Dec 5, 2012
* Changes by Stephanie Allison:
Add LSV and LLSV for MEM_FREE and RAM_WS_FREE.
Add MEM_FREE to limits display.
Update RELEASE files for LCLS.
* Changes by Judy Rock:
Add START_CNT (ioc startup counter) to database and displays.
iocStats-R3-1-10: Jun 26, 2012
* Changes by Helge Brands:
- add ioc_stats_scanmon.adl
- add devIocStats/os/WIN32 files.
NOTE: For EPICS base 3.14.12.2 and below, this patch to rsrv.h
for casStatsFetch is required (and a rebuild of epics base):
http://epics.aps.anl.gov/epics/base/R3-14/12-docs/rsrv2.patch
- move epicsExport.h inclusion to later for WIN32 builds.
- bug fix for total memory more than 4GB.
* Changes by Stephanie Allison:
- Check for null pool pointers for vxWorks.
- Correct vxWorks 6 compiler warning.
- Correct epicsFindSymbol logic.
iocStats-R3-1-9: Mar 13, 2012
* add generalTime records to soft IOCs (database and display).
iocStats-R3-1-8: Dec 4, 2011
* improvements for non-posix targets.
iocStats-R3-1-7: Dec 1, 2011
* iocAdmin/srcDisplay/Makefile - use EDL file type.
* Changes by Tim Mooney:
- copy all devIocStats/os/Linux to devIocStats/os/cygwin32.
- add devIocStats/op/opi CSS/BOY display files.
* all src Makefiles - build only for
RTEMS, vxWorks, Linux, solaris, Darwin, cygwin32.
Mark Rivers reports that iocStats will not build for WIN32.
* add devIocStats/os/default/devIocStatsOSD.h dummy file.
iocStats-R3-1-6: Aug 11, 2011
* Change by Robert Henning and Stephanie Allison:
- Add medm displays to op/adl. Original displays by Robert
and brought up-to-date with the edm display by Stephanie. Could
use more work.
* Change by Eric Norum and Stephanie Allison:
- Add check for IOCSH_STARTUP_SCRIPT when setting startup script (after
all the other existing env vars).
- Support for RTEMS 4.10.
- Move ENGINEER and LOCATION records from general env vars back to
IOC stats support.
* Change by Judy Rock:
- iocAdmin/src/iocReleaseCreateDb.py - look for epics base version in 2nd
argument if not found in the first.
- configure/RULES_BUILD - add 2nd argument to iocReleaseCreateDb.py rule.
* Change by Sonya Hoobler:
- iocAdmin/srcDisplay/ioc_stats*.edl - correct READACF command. Add
confirm display for reloading the access security file.
* Change by Stephanie Allison:
- iocAdmin/Db - remove baseSecurity.acf, remove ASGs in templates.
Add TODFORMAT macro to TOD (time-of-day) records.
- Move common logic from os/*/osdBootInfo.c to devIocStatsString.c.
- Bug fix for RTEMS - initialize IF error counters before loop.
- Add CPUBURNSQRT compile switch use the sqrt burn instead of the
epicsTime burn in devIocStats/os/vxWorks/osdCpuUsage.c. The default
is epicsTime which gives a CPU load of 0% when ioc is not busy.
Add code to prevent double init of vxWorks osdCpuUsage.
iocStats-R3-1-5: Mar 31, 2011
* Change by Eric Bjorklund:
- devIocStats/os/vxWorks/osdMemUsage.c - correct vxWorks meminfo structure
update. vxWorks 6 has a completely different layout.
* Change by Stephanie Allison:
- devIocStatsAnalog.c - correction for 64 bit.
Note: iocStats releases above R3-1-3 require EPICS base 3.14.11 or above.
Edit the following files for EPICS base 3.14.8.2:
- iocAdmin/Db/iocAdmin*.substitutions - remove iocGeneralTime.template.
- iocAdmin/Db/ioc.template - remove alias line for IOC_CPU_LOAD and
give the record the desired name. Remove alias for SYSRESET.
- iocAdmin/srcDisplay and srcRestore - change IOC_CPU_LOAD in files to
the desired name.

creating a display with RELEASE module versions..
* configure/RULES_BUILD - Remove rule for building a display

iocAdmin-R3-1-0: July 7, 2009
* devIocStats - Ralph Lange made changes. Here are his notes:
Functionality is basically as before, the main work (quite a bit more
than I expected) being the split-up of all the devIocStatsOSD.c files
into functionally separate source files. (So that any single
functionality may be not implemented for an architecture and fall-back
to os/posix or os/default.) That split-up includes new names and APIs
between the generic part of the device support and the OSD parts,
which I tried to streamline, which allowed for some serious code
simplifications in the generic parts. I also made sure the new APIs
will make it a lot easier to support waveform records.
I fixed a few bugs in the code (IFerrors and uptime under vxWorks) and
added (in the attached version) kernel version and CPU usage info for
posix systems.
Added mem->total to the meminfo structure to create reasonable
information on soft IOC implementations with virtual memory
organization:
total: on this host - physically installed memory.
used: for this IOC - physical memory used at the moment (RSS)
free: on this host - physical memory that is available to
processes (free plus cache plus buffers)
Added memory implementation for Linux, FD usage implementations for
Linux and Solaris.
* iocAdmin/srcDisplay - LCLS display update.
* iocAdmin/src - Added python scripts by Dayle Kotturi for automatically
creating a database and display with RELEASE module versions..
* iocAdmin/Db - Add iocAdminSoft and iocAdminRTEMS databases for soft
and RTEMS IOCs. Add MEM_MAX. Process CLUST records only after MBUF_FREE
records are processed.
* iocAdmin/srcRestore - Add iocAdminSoft.cwConfig for soft IOCs.
* configure/RULES_BUILD - Add rules for building a database and display
with RELEASE module versions.
iocAdmin-R3-0-0: Apr 29, 2009
* Built against EPICS R3.14.8.2 and RTEMS 4.9.1 (base-R3-14-8-2-lcls3)
* devIocStats/os/RTEMS/devIocStatsOSD.h - change by Sue Witherspoon so that
bsp_reset is only used for PPC and uC5282.
