Re: disk space / network monitor in iocStats?

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.
