Hello,

iocStats (aka devIocStats) version 3.1.3 is released and available from the EPICS Application project [1] on SourceForge:
http://epics.svn.sourceforge.net/viewvc/epics/applications/tags/iocStats/3-1-3/
SLAC Web Page: 
http://www.slac.stanford.edu/grp/ssrl/spear/epics/site/devIocStats/

This release is a combination of effort by Ralph Lange, Eric Norum, and myself and includes these changes:
(1) Support for system CPU load and number of CPUs for Linux, Solaris, and MacOS.
(2) Change to IOC CPU utilization so that it returns 0%-100% of CPU load with respect to the system (divided by the number of CPUs where applicable).  BTW - None of the available methods returns a true value for CPU utilization for multi-threaded applications on multi-core systems. 
(3) Addition of scan monitoring based on Kukhee Kim's devScanMon developed during the Diamond code-a-thon.
(4) Removal of some unsupported files, renaming of a few files, reorganization of the test directories.

Some of the files that were removed include ones that came from the old LBL vxStats package - plus I see them in PSI iocmon too.  Does anyone know more about these files and if they are important enough to resurrect and make work on all host platforms?:
ioc_stats.c, rdbapplist.c, rdbls.c, BSLib.c, PVSvx.c

Thank you,
Stephanie Allison

iocStats contains device support collecting all kind of useful statistics and information for an IOC:
* General things: host name, uptime, BSP, OS, and EPICS versions, current directory, ...
* EPICS and Channel Access numbers: no. of records, no. of active clients, no. of connections, ...
* Usage numbers: Memory, CPU, file descriptors
* Network: MBUF statistics, network interface error counters
* Memory system: Cluster statistics
Almost all features are implemented on vxWorks and RTEMS, an increasing number
for softIOCs on Linux/Solaris/MacOS, some things work on Windows.
