Experimental Physics and Industrial Control System

Hi Matt,
I placed our iocStats (with network statistics for Linux and RTEMS 4.10, detection of not connected ca links and not connected PVs used by the seq programs) which we use currently in LBNL to my github with the intention to merge it with the official version of epics_modules/iocStats
Currently you can clone it from and then change the branch to network.
It is included the test ioc testIocNetStatsApp which you can use as a reference. Examine the testIocNetStatsApp/src/Makefile to see how to link the iocstats library when the sequencer is used.
Best Regards Mirek
[I have tried to send this mail already but it seems lost in cyberspace. If you you got it already, sorry for the
duplication.]
At PSI, we are not using IOCMON any more but iocStats. And yes, I have added support for disk space.
Our version is here: https://github.com/paulscherrerinstitute/iocStats
This is the template (instantiate once one per disk):
https://github.com/paulscherrerinstitute/iocStats/blob/master/iocStats/iocAdmin/Db/iocFsStats.template
And here are the implementations for posix, vxWorks and Windows.
https://github.com/paulscherrerinstitute/iocStats/blob/master/iocStats/devIocStats/os/posix/osdFileSystem.c
https://github.com/paulscherrerinstitute/iocStats/blob/master/iocStats/devIocStats/os/vxWorks/osdFileSystem.c
https://github.com/paulscherrerinstitute/iocStats/blob/master/iocStats/devIocStats/os/WIN32/osdFileSystem.c
It uses our PSI build system and several PSI internals but you may want to merge the changes with the "official"
iocStats.
