Re: disk space / network monitor in iocStats?

[Tynan Ford via Tech-talk <tech-talk at aps.anl.gov>]

There is IOCMON from PSI that contains some network statistic support for VXWorks: http://epics.web.psi.ch/software/iocmon/ 

We at ALS are using a similar idea from this to monitor network statistics on our linux servers. A colleague worked on that and we can discuss that more or share the code. We don't have disk space stats but that would be interesting.

To address the PV duplication, we ended up separating the existing iocStats database into 2 separate files. An "IOC-specific" stats database and a "System-specific" database. Then for each of our soft IOC servers, we have one dummy soft IOC that simply loads the system stats database.

Best,

Hi,

Has anyone thought about adding disk space (or, rather, file system mount point) statistics and network statistics to the iocStats module? Or, is there another module that can already do this? Or, is this a sensible idea?

This may only be relevant for soft IOCs. Also, it would be redundant for multiple soft IOCs to all be monitoring disk/network use if they are running on the same machine. I am thinking about a single 'system IOC' that could monitor things like:

Overall CPU load
Overall memory
Overall file system use (Size, %Used)
Overall network use (In/Out Bytes/s)

Not really aiming to replace dedicated system monitoring tools, but getting a few of these important parameters into EPICS can be useful.

I know iocStats is already providing overall CPU and memory use, but not network or disk space.

Cheers,
Matt
