Re: disk space / network monitor in iocStats?

[Miroslaw Dach via Tech-talk <tech-talk at aps.anl.gov>]

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

https://github.com/mirek23/iocStats.git

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

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.
