Cheers, Niki ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos Hi, The suggestions offered by other posters to install/use a monitoring/polling/graphing system is a fine idea. Using something like Cacti is great for collecting and viewing historical data. However for looking at what a server is doing _right now_, that kind of system falls short. I think your original idea is spot on! I do exactly what you suggest. I keep a minimal X install on most of my headless machines -- I still boot run level 3. This lets me ssh -X to a machine and execute graphical commands, and up the come on my local Linux workstation. Occasionally, this is very useful for me. For instance: I have some of these headless boxen scattered throughout the network. With this, I can launch firefox on a remote machine. This lets me test viewing resources from various points of the network; great for security policy testing. What you're talking about works great too. I have gkrellm installed on these machines too, as well as the servers. Cacti is great for looking at trending or historical data. But to see what a server is up to _right now_ I fire up gkrellm this way (along with things like tail 'cat /var/log/_something_' and htop) to see what the machine is up to right then and there. gkrellm is available from the wonderful rpmforge repo, but I'm sure Conky would work too.

You can take this one step further by picking an always-on host where you run freenx. Then connect with the NX client from www.nomachine.com and start a desktop where you can park long running jobs like monitoring tools (including remote X connections or a bunch of xterms with ssh connections elsewhere). Then you can disconnect the NX client and reconnect later with everything still running. The connection can be from any linux/windows/mac NX client and you get very good remote performance even over low bandwidth connections - and unlike normal X connections, losing the connection doesn't kill the processes. -- Les Mikesell lesmikes...@gmail.com ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Les Mikesell a écrit : If you use X remotely much, just take the whole desktop with freenx on the server and the NX client that you can download from http://www.nomachine.com. It is very efficient and lets you disconnect/reconnect with everything still running, even from a different client - or even platform. Yeah, I'm a happy user of FreeNX already... although I don't use it for the kind of problem at hand. I've been working for a small company recently who run Ubuntu 8.10 on a server, and all their desktops are in fact FreeNX clients connected to that one machine, so folks can work even from their homes. Works great. Niki ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Works great. You can run multiple NX sessions if you want your 'own' desktop plus one for monitoring/managing other systems. However they are likely to pick the same display number and conflict if you are the first connection to each freenx server. You can avoid this problem by changing the DISPLAY_BASE setting in /etc/nxserver/node.conf (after copying from node.conf.sample). It's also much nicer for interacting with VMware guests than the VMware console tool after the network is configured and working. -- Les Mikesell lesmikes...@gmail.com ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] Monitoring a remote server with Conky ?
Hi, I've been using Conky for some time, a nifty utility to monitor just about anything on the PC.

Re: [CentOS] Monitoring a remote server with Conky ?
One more vote for gkrellm. You can install gkrellm-daemon from the epel repo on the server and then monitor from your workstation.

Cheers, Niki You typically do not monitor servers with these kinds of tools. They are made for workstations that have real people sitting at them. What you want for servers is software that saves to a log file, and then you view the log files as you desire. One of the most common tools for this is 'sar', which is part of the systat package. There is an interesting GUI tool for it called kSar that can use the logs from sar and generate graphs. For realtime monitoring, one would typically look at snmp and cacti to generate graphs, send alerts, etc... ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Cheers, Niki Hi Niki, You could try a local script that gets values from a server that you would like to monitor... I might suggest looking into setting up snmpd on the server and using snmp walk to probe specific values (that relate to processes/free memory).

While you take suggestions - look also for collecd. It's very easy to setup, customise and interogate graphs.
