Which CTID for a PID ? [message #44790]

Hi, I'm having freeze problems in a server with CentOS 6

tested with 2.6.32-042stab039.11 and 2.6.32-042stab044.11

server blocks and not any error in secure o messages logs.

I have started a console with "htop" command running, and in all downtimes I see a httpd process with 60% of CPU load.

How can I see what VM is running this httpd command?

I try to install vztop, but seems dont run with CentOS6, only with CentOS5.

Any idea to find the malicious CTID ?

Thanks!!

Which version of htop do you have?

htop can show the CTID of processes, you have to configure htop to do that. Inside htop, go to Setup -> Columns -> Add CTID from the "Available Column" to the "Active Column".

'man vzpid' is your friend too even if you do not have htop.

Hi, thanks for your response, I use:
htop-0.9-1.el6.rf.x86_64.rpm

I think is the latest version, but in available colums, I dont see CTID

It's possible I dont use the correct version?
Thanks!

The problem is that opevz support needs to be enabled at compile time and most of the htop rpms I've seen don't have it. You'll need to either rebuild the rpm and change the switch or build from source.

Trying to install in CentOS 6, I get error running the ./configure

checking for refresh in -lncursesw... no
configure: error: You may want to use --disable-unicode or install libncursesw.

I do ./configure --disable-unicode
and I get this error:

checking for refresh in -lncurses... no
checking for curses.h... (cached) no
configure: error: missing libraries:  libncurses

# rpm -Uhv ncurses-libs-5.7-3.20090208.el6.x86_64.rpm
Preparing...                ########################################### [100%]
        package ncurses-libs-5.7-3.20090208.el6.x86_64 is already installed

Any idea to compile htop in CentOS 6 ?

Thanks.

So you have built it with, if I remember correcty, --enable-openvz switch?

If so, than you need to enable VPID in htop setup. Run htop, press F2, go to "columns" and add VPID.
