I have a server (LDAP and NFS) which occasionally seems to take a while to react. Load average is consistently high (10-12 for 4 CPUs, which AIUI means 2.5-3 per CPU); response may also be being affected by disk I/O.
I’d like to find out which processes in particular are causing the heavy load, and possibly also to track disk I/O activity over say a 24 hr period. Unfortunately, this has exposed a shocking lack in my knowledge, viz: I have no idea how to do this, what tools are out there, etc etc. (Obviously I am fortunate never to have encountered performance issues before; all my machines have previously either Worked or Not Worked.) Any suggestions?
(The other possibility is a network load issue, but as I’m not responsible for the network, tracking that might be tougher.)
Another, unconnected query: I have been asked to source quiet/silent keyboards for a couple of my colleagues who are noisy typers. Any recommendations? I’ve looked at the Saitek Eclipse but it sounds like it’s not very tough. Bonus virtual biscuit for recommendations which are actually available to buy in the UK (the IBM Quiet Touch appears not to be, for example). Real biscuit available to anyone able to implement a biscuit-over-IP protocol; failing that I shall just eat them all myself.
