Thanks for pointing out OSW!
We've always used tools to match the OS ("collect" for Tru64, "nmon" for
AIX, a home-grown sampler of /proc for Linux), then created .csv files,
built external tables off the .csv files, then loaded the data into an
Oracle db for historical analysis of the stats.

Subject: heavyweight OS monitoring as standard
I'm at Collaborate right now, and we just finished the RAC SIG
bird-of-a-feather session (it's a group discussion, and was quite good).
Had an interesting point come up - we were discussing troubleshooting
and asked how many people ran OSW as a standard practice on their
clusters. (Metalink note 301137.1) I think about half the room raised
their hands.
OSW is also included in RACDDT. (Metalink note 301138.1) And there's
also a new tool from Oracle called IPD which seems to gather similar
information into a little Berkeley DB (running processes, runqueues,
etc):

ad_homepage.html
How many people on this list install OSW as a standard practice on their
database servers? Do you install some other heavy-weight monitoring tool
as a standard? I always thought that most people only installed
light-weight monitoring tools by default, would only install something
like OSW and if there were problems since it captures so much data. But
maybe this should become a standard practice for us; it would make
troubleshooting machine crashes after the fact a *lot* easier.
Any thoughts?
