Last time I looked there weren't any tools that did this in an accurate way. Admittedly, it has been a while. The approach I took was: On every global zone: 1) Enable task accounting. In 2005 Adrian Cockroft had a few blog posts about this. See http://perfcap.blogspot.com/ 2) Process task accounting records every 2 minutes, summing by zone 3) Send task accounting and various kstats related to memory, network, etc., and other data (vmstat, iostat, etc.) to a central server as soon as the data is gathered. This is over a TCP session. The central server (really a zone with adequate storage) 1) Read data from clients as it comes in 2) Store a copy of the raw data just in case you need to do other types of analysis (excel, R, etc.) 3) Update rrd files. There is then a simple CGI program that is able to present the RRD files. The beauty of this is that I never configure anything. The part that goes on every global zone is baked into the server installation procedure. New zones are picked up as soon as they first boot. I am able to store 2 minute resolution data for ~ 40 days, 10 minute resolution for ~6 months, and 30 minute resolution for 3 years in about 200 MB per global zone plus about 10 MB per zone. The CGI interface can tell me somewhat detailed data about activity that has happened in the past few minutes and any other period up to 3 years ago with a response time of a couple seconds or less. I would love to hear that there is a pre-baked tool out there that can have this level of simplicity, but have a prettier interface than the CGI interface that I came up with. The core of this tool was written (pre-S10 days) over the course of a weekend due to my dissatisfaction with the tool that I had to use that would page me all night long but took over 10 minutes to give me historical data (last 30 minutes, did it do the same thing last week?). Someone I was talking to recently appropriately tagged this as "software written out of spite." I like that. :) You might get other insights at sysadmin-discuss as well. -- Mike Gerdts http://mgerdts.blogspot.com/ _______________________________________________ zones-discuss mailing list zones-discuss@opensolaris.org
