[Condor-devel] Master ad tweak proposal

[Peter MacKinnon <pmackinn@xxxxxxxxxx>]

It would be nice to incorporate a few additional attributes into the 
Master daemon ad so that it could serve as a record of inventory for a 
pool. A management console (like Cumin) could then use this information 
to display host load average and current RAM/swap usage independent of a 
configured startd and its attendant slot breakout ads and attributes.

# from /proc/meminfo
    TotalMemory
    FreeMemory
    TotalSwap
    FreeSwap

# from /proc/loadavg
    LoadAverage

# from /proc/loadavg (threads)
    TotalProcs
    RunningProcs

Some of these have existing condor_sysapi generators like 
sysapi_swap_space and sysapi_load_avg. DetectedMemory is already present 
in the Master ad. The new free swap/memory attributes would need basic 
calculations if I'm not mistaken.

Appreciate your feedback.

Thanks,
\Pete
