Hi,
In our environment, we are collecting SAR files from Linux (SuSE-11/Redhat-5/Redhat-6) servers and using ksar to generate graphs. All the Linux servers are VM's that are hosted on the vmware infrastructure. The ksar graphs are put in the http doc root to be accessed via browser.
We have observed that the ksar utility does not show amount of CPU time spent on I/O wait in the graphs for some servers SUSE11-SP4 (SAR - sysstat version 8.1.5) & RHEL6.6 (sysstat version 9.0.4) . This is not an issue for the graphs generated for sar files of RHEL5(SAR - sysstat version 7.0.2) servers.
The kSar version that we are using is "kSar version: 5.0.6".
Also the Java version that we are using is:
java version "1.7.0_101"
OpenJDK Runtime Environment (rhel-2.6.6.4.el6_8-x86_64 u101-b00)
OpenJDK 64-Bit Server VM (build 24.95-b01, mixed mode)
If you have come accross this issue, please comment / suggest or point me in the right direction.
Thanks.
