Re: [Vserver] Wiki : HowTo graph vserver usage with cacti
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 hi, 2005/12/16, Herbert Poetzl [EMAIL PROTECTED]: in general, if there is real interest, and folks (at least 3 parties) are volunteering to test and add the required userspace tools/interfaces, please contact me with a wish list (i.e. what kind of information you would like to monitor) and we can probably get an implementation done ... (of course, funding such features migh be an alternative too :) Grzegorz Nosek wrote: Count me in for testing :) My wishes for vserver monitoring include: - loadavg and cpu% (somewhat faster than parsing /proc/virtual/*) - network traffic (again, somewhat faster than iptables stats, a'la /proc/net/dev maybe) - reliable memory usage (current implementation apparently doesn't account for shared memory, like libraries) - disk i/o - process-related stuff, like fork rate might be useful (ideally per-user but that'd be quite an overhead probably) Matt Gorecki wrote: I would be interested in all of the above. Particularly in network traffic, memory usage and cpu utilization. and me too! basically, will have a production environment of greater than 1 physical host and many vserver guests with which it would be great to be able to achieve some kind of balance across the physical hosts of the vservers, appropriate to their capabilities. i guess that, in particular, the interest would be: - cpu usage - memory usage - network/bandwidth information - hard disk usage all of these on a per-vserver basis (as well as monitoring the physical host, which it seems i can already do). currently, i am using munin [1], which gives good reports based on the physical host and also on all the vservers bunched together as a group, it seems. cacti has been recommended tho, and i don't know how they compare but first glances at the cacti[2] site seem encouraging.

[Vserver] Script testfs.sh on Reiser3
Group, I find differences between lsattr and showattr outputs which the script marks as errors. Background: Linux 2.6.14 on x86 with vserver 2.0.1 applied. util-vserver 0.30.209 ReiserFS 3.6.14 Distribution layout is basicly Debian Sarge Note 1: script expects a mkfs.reiserfs so I faked it with: ln -s /usr/sbin/mkreiserfs /sbin/mkfs.reiserfs Note 2: script calls lsattr (part of e2fsprogs) which means that versions prior to 1.37 will silently fail. I built e2fsprogs 1.38 to get past that one. Here is what I am seeing, all that I can tell is that the attributes reported are different: Without the (-o attrs) option to mount command [mount /dev/loop0 /mnt] # showattr /mnt ---bui- /mnt ui- /mnt/file_9079 ---bui- /mnt/dir_9079 # ./lsattr /mnt/ ./lsattr: Inappropriate ioctl for device While reading flags on /mnt/file_9079 ./lsattr: Inappropriate ioctl for device While reading flags on /mnt/dir_9079 (Which seems reasonable) Note 3: Some of the on-line documentation mentions an xattrs option to reiserfs - my 3.6.14 only understands attrs (correct in the script). Next, umount and mount the test file with the attrs option [mount -o attrs /dev/loop0 /mnt] Now we have (without any changes to the files) # showattr /mnt ---bui- /mnt UI- /mnt/file_9079 ---Bui- /mnt/dir_9079 (Notice the changes of case with the addition of attrs that is going to bite somebody running Reiserfs. ) # ./lsattr /mnt/ i /mnt/file_9079 - /mnt/dir_9079 Which translates as: # ./lsattr -l /mnt/ /mnt/file_9079 Immutable /mnt/dir_9079--- The only conclusion I can reach is either something is broke or incomplete in lsattr or Perhaps the script should not be expecting that the output of lsattr on a reiser3 filesystem to make any sense. PS: anyone tried this on reiser4? Mike ___ Vserver mailing list Vserver@list.linux-vserver.org http://list.linux-vserver.org/mailman/listinfo/vserver
