well,without any personal experience, what I heard about Munin was that it was quite easy to setup, and did a lot for you, but it was not 'light weight' by any stretch.

I use Munin.

If you intend to monitor many hosts, that will lead to tons of charts to draw periodically. This is very I/O consuming, and you have to make sure you have enough for that, or spend some time to reconfigure the nodes to reduce monitored resources.

Munin is easy to setup because it has configuration suggestions: it might monitor ressources that are useless for you.

Thanks Mihamina. I only want o monitor these 5 vms and nothing more ...

I've heard Munin is easier to setup.

Personally, I like OpenNMS but it is probably even bigger. But RAM is cheap these days and it is nice to start with something that will scale up if you need it later.

Hi all,

I have a test lab installed over an ESXi 5.1 host that contains 5 CentOS vm guests. I would like to monitor CPU, RAM and Network for these vm and ESXi host. Zabbix and Nagios are too to accomplish this task. Does anyone know any lightweight openosurce soft to do this??

Thanks.

Hello, This might end up being off-topic if the answer is in some kind of php or other client-server script. So, here is what I wanted to ask... I can use Samba to share things on my local network with Windows even. I can get a view of my desktop from Windows using tightvncviewer with vino running on the Centos box. Here is what I was curious about doing... One is to have a filesync and backup like Dropbox for sharing and accessing files from anywhere. There would need to be a client app that ran on a Windows device, or even a tablet/smartphone that automatically synced a certain folder or folders that you identify. On Dropbox you select one top folder/directory. Or perhaps there could be like a virtual drive (on windows we deal in drives instead of the unix file system). This might already be doable to create a map to a network drive. I don't know if that would work over the internet if one had the laptop outside the local network and you wanted to see certain files. Not sure if the network drive would show up in this scenario. I'm looking for options for non-techie people like my wife and many of my clients - the latter often need to get me images and other assets. The other issue is streaming media to devices like my tablet, or other devices, pcs, from the Linux Centos box. Not sure if a Node.js solution is best or a php solution and/or if there are linux apps for Centos that do this. Thanks, Bruce

This is a great tool. Thanks. What is a bit frustrating is that some of the modules do not seem to work for some reason. For example, it finds the music files and there is an enabled music player but I never get the files to play. On my Ipad, it wants to download everything, also. Instead of streaming it (both on the Windows Desktop and the iPad) it will not stream. Actually, I get something that looks like a player in the web interface, but clicking on Play does nothing.

       The other issue is streaming media to devices like my 

tablet, or other devices, pcs, from the Linux Centos box. Not sure if a Node.js solution is best or a php solution and/or if there are linux apps for Centos that do this.

Any opinion on whether these things can be integrated with ownCloud? If anyone else has an opinion let me know. I'm guessing that many folks on this list are very familiar with php. It was amazing that owncloud did everything with just php. I had some other issues but perhaps I need to take that to an owncloud forum. Like why I ran into problems installing an app. I tried one that was supported. I downloaded it and uploaded it to my Centos box, inside the apps folder on owncloud. First I get an error when I tried to do anything as admin. It says that the folder doesn't have write access - the apps folder. Inside the httpd.conf file, I setup the user/group to be apache:apache. So, I first made sure the folders had that user/group setting for ownership (using chown). Then I ran the command: chmod +w -R apps from inside /path/to/domain/public_html/owncloud/ So, even after doing this, first: chown -R apache:apache apps and chmod +w -R apps, it was still showing that error message and telling me I had to change ownership and make things writable. I think I had to logout of the site from Chrome browser and log back in to get this to work again. My copy of firefox is not working too well with this which may be a larger firefox issue. Thanks, Bruce

Hello, I do have virtual hosts setup. I registered one domain and used a second service that allowed me to use a subdomain on their domains and have it point to my IP for my server (the external IP). This might let me give permissions to someone to help me if I get stuck. This might be off-topic on a Centos list, although some issues do seem to relate to setting permissions, ownership, virtual hosts and etc. For example, I have the registered domain setup as the first virtual host and this is done inside the httpd.conf file. So, it's basically inside ./html/public_html/ Then my second domain is setup in a vhosts.d config file. But I didn't associate a user with that. Therefore both domains seem to require that the owner is apache:apache, which is set in the httpd.conf file. How do I setup domain2.com as a second (or third) virtual host *and* setup a username/pw for accessing that domain and others.

Apache is infinitely configurable. And web login users normally don't have anything to do with the permissions on the underlying files and directories. See http://httpd.apache.org/docs/2.2/howto/auth.html. You'll have to decide how you want to store the passwords and set up the restrictions on the top-level directory for each site. http://httpd.apache.org/docs/2.2/howto/auth.html

It's just saying the records don't match from your parent nameserver.

As you can see, the parent server returns two NS records. But here is the NS records from your server.

[root@janus ~]# dig ns maca.li

You don't specify these two NS records from your parent. Just need to add these two, you will be fine then.
