Xen Dom0 performance reporting/monitoring
...gies if this has been covered many times before, but I''m unsure how to go about this. I want to obtain stats from my dom0, IO, cpu etc over time to see if I''m getting any load peaks or if my hardware could handle more domU''s. I''m thinking of something similar to sar which gives you 15 minute averages across the day. I have read that the sar stats should actually show in the dom0 just like it''s a normal machine, is that the case? When I''ve watched a dom0 and domU running top at the same time, the spikes in domU are never reported back at the...

XenServer 5.6 FP1 - CPU utilization using sar
Hi all, Using XenServer with a RHEL6 beta VM, I have sar installed on the hypervisor and VM. If I do a ''md5sum < /dev/urandom'' to spike CPU usage on the VM, I see the indication on the XenCenter performance graph on CPU 0. It does increase quickly. Neither sar output gives any sort of indication that the CPU is being loade...

Huge amount of used inode handlers reported by sar -v (inode-sz)
...concerning this problem (no reply) and looked through the Redhat errata, and google etc. I''ve also checked the proc filesystem and can''t find any large numbers in inode-nr etc. The only way I''ve found to get rid of the problem is a reboot.

cpu load monitoring
Hi, I have a server running Centos 5.2 and am implementing a GIS mapserver app. I have some sample logs from another implementation that give me an idea of bandwidth requirements but I would like to check the cpu load. I can not be at the server during the test and am interested in knowing if there is logging of cpu load available. Anyone have experience with this? Recommendations? Dave --

strange sar statistics: total CPU 90% in userspace, but CPU 0 and 1 only 1%
Hi Centos Users The server (ProLiant DL380 G5, Centos 4.3) was not responsible anymore (SSH), fans rotated at full power and the console was blank. After restart it seems to be fine. Now I am analyzing sar statistics (in system logs nothing special, unusual). The hardware monitoring with HP tools didn''t work. # sar -P ALL Linux 2.6.9-34.ELsmp (cent061) 01/15/2008 12:00:01 AM CPU %user %nice %system %iowait %idle 12:10:01 AM all 90.43 0.0...

sar -n DEV does not show bonded interfaces
Anyone know how to get statistics on bonded interfaces? I have a system that does not use eth0-3, rather we have bond0, bond1, bond2. The members of each bond are not eth0-3, rather they are eth6, eth7, etc. I didn''t see anything in the man page about forcing sar to collect data on specific network interfaces.

(Note that it would NOT work if we omitted library(RH2) since the default sqlite back end does not have date types and does not know that an R date -- which is sent to sqlite as the number of days since 1970-01-01 -- corresponds...
