Hello , After upgrading the system from CentOS 7.2.1511 to CenOS 7.3.1611 I see that the average processing time has increased from 5-7% to 12-15% (doubled). Not critical but it is not pleasant. Server as KVM with 5 virtual machines. Someone noticed something similar? If so, how to fix that? Thx.

Hi -- I'm running a server which is usually stable, but every once in a while it hangs. The server is used as a file store using NFS and to run VMware machines. I don't see anything in /var/log/messages or elsewhere to indicate any problem or offer any clue why the system was hung. Any suggestions where I might look for a clue? -- Michael Eager eager at eagercon.com 1960 Park Blvd.,

We are currently running CentOS 5 update 4 on a Dell R910 server 16 cores/32 hyperthreaded with 64GB of memory. It is our main Oracle 11g DB server for one of our customers and is attached to an MD 3000 storage array. We are having a load averaging around 5 but see no swap in use, CPUs are pretty much idle and no I/O wait. We have Oracle dataguard turned on in transactional mode. I've checked

Is there a package I can get that will graph system resources such as CPU and disk I/O to an html file or something? Matt

Both tools response time are good but if we connect through application like Web browser, database,

Hi, I've been using Conky for some time, a nifty utility to monitor just about anything on the PC.
