Here's some basics. This is the statistics for one machine (so double would be our daily, approx):
March 31, 2009 TOTAL AUTHENTICATIONS: 47354 PER HOUR (00 == midnight, for the non 24-hour inclined): 1711 00 1043 01 639 02 339 03 213 04 179 05 288 06 659 07 1485 08 2422 09 2860 10 3254 11 3239 12 3199 13 3042 14 3042 15 2777 16 2417 17 2446 18 2320 19 2422 20 2634 21 2529 22 2195 23 These are just authentications, not proxying, service tickets, etc. On a normal day (which these stats are), you could barely even tell the machine was doing anything. I think normal usage is < 5% CPU utilization each on the new machines. I can get other stats if you're interested. Our portal is what drives most of our traffic to CAS. -Scott On Wed, Apr 1, 2009 at 2:21 PM, Johan Reinalda <[email protected] > wrote: > Scott, > could you give an idea of how many authenticated users you have ? > (Is there a way to monitor that with the regular memcache, or repcache > ticket registries ?) > > We are current plannin on rolling our for the fall semester at Thunderbird, > and are looking at scoping hardware also...
