I've made different scripts already to be able to monitor daemon stuff through cacti, and was planning on making on one side some nice graphs about load and memory and such, and otherwise an overview page with all the info on it. I would suggest you look at collectd : http://collectd.org/ It collects system information every 10 seconds and writes it into an RRD database. It is implement in C and seems to consume almost nothing in term of ressources on the host. It can monitor vservers too! And it is dead simple to configure. It comes with a simple Perl CGI script to display the graphs. Have a look at these examples : http://tokkee.org/cgi-bin/collection.cgi http://tokkee.org/cgi-bin/collection.cgi/vserver-42097 http://zethradon.no-ip.org:36987/cgi-bin/collection.cgi The first two links point to the server of the author of collectd (Sebastien Harl). The second is an example of vserver monitoring. The third link is my personnal machine. I plan to integrate collectd to vsmon eventually. -- Guillaume Pratte Recherche et développement Révolution Linux Toutes les opinions et les prises de position exprimées dans ce courriel sont celles de son auteur et ne répresentent pas nécessairement celles de Révolution Linux.

Still planning to do that when time permits though ;/ -- the hard part is looking up where to find all that info without having to parse vserver-stat etc :) let me chime in here and add a few thoughts to this: on recent kernels (means current devel, soon to be stable branch) we have (almost all) interfaces to provide guest status and overview directly from the kernel, without parsing proc interfaces and doing a lot of calculations (as vserver-stat currently does and often gets wrong) although I hope that in this process, the vserver-stat will get an overhaul too, it would be a good idea to have a look at the direct API and the derived libraries (contact Hollow, phreak``? and maybe daniel_hozac for more details) the interesting part here is that those interfaces provide fast and unambiguous data about guests like - current status and uptime - number of processes - various accounting data including sockets - current limits, max/min and hits - uts information - load and time virtualizations and much more ... also note that we will change the proc interfaces slightly in the future, as we will switch from ticks (jiffies) to the more comprehensible ms (milisecond) unit best, Herbert Thanks, Tom ___ Vserver mailing list Vserver@list.linux-vserver.org http://list.linux-vserver.org/mailman/listinfo/vserver ___ Vserver mailing list Vserver@list.linux-vserver.org http://list.linux-vserver.org/mailman/listinfo/vserver
[Vserver] Virtual server monitor
Hello, I would like to have the opinion of the mailing list about a tool I just released called 'Virtual server monitor' or 'vsmon' for short : http://vsmon.revolutionlinux.com/ It is a web-based interface with the primary feature to list all vservers running on all hosts visible by the interface. It also displays some basic statistics such as uptime, memory usage, number of process, etc. Basically, it is a distributed vserver-stat on steroids :-) It was developed to answer the question Where the heck is that vserver running?, and thus offer a web page where it is possible to use the find dialog of the web browser to trace back on which host a particular vserver guest is running. It is developped entirely using Python. The web frontend uses Django [1], one of the best Python-based web framework currently available. Communication between the backend and the frontend is assured by Pyro [2]. [1] http://www.django-project.com/ [2] http://pyro.sf.net/ I am aware of the existance of OpenVCP, but I chose to write my own application, one reason being that I wanted to develop using Python all the way and not C and PHP. For now, the only easy way to install vsmon is by running Mandriva 2006, but I hope to support Debian also in the future. Installing by source is possible, but not easy. However, I will provide support to people posting on the vsmon mailing list (https://lists.sourceforge.net/lists/listinfo/vsmon-users). Feedback is appreciated :-) Thanks, Guillaume Pratte Software engineer Revolution Linux http://vsmon.revolutionlinux.com/ -- Any views and opinions expressed in this email are solely those of the author and do not necessarily represent those of Revolution Linux. ___ Vserver mailing list Vserver@list.linux-vserver.org http://list.linux-vserver.org/mailman/listinfo/vserver
