Nagios
 

I like Nagios because I can monitor my whole machine as well as network usage. Plus it has the easiest quickstart guide for most common linux flavors.

I've not seen much else that captures netflow data like ntop.

For a full network monitoring Solution I like Zenoss. Zenoss also has direct support for all the Nagios plugins..

Hi folks,


Thanks for your advice.


Just found ntop/Nmon on Internet googling. Neither I have knowledge on this package. I'm prepared to test it. However before injecting effort on it I expect to know whether there are better alternatives avoiding spending time and effort on secondary tool.

it really depends on the data you are looking to monitor, as to what is the right tool for the job.

Farslayer has pretty much hit it on the head. ntop was very useful when I needed in depth analysis of a specific network link. For instance I needed to see all network traffic hitting the default gateway to find which boxes were the top talkers on the network. ntop enabled me to evaluate all network traffic and find which hosts were causing the issue.

On the other hand if you are looking for up/down monitoring and machine specific statistics some of the other tools mentioned will be a better choice.

Ditto; if you are looking for system up/down/avail etc also checkout OpenNMS, zabbix

Thanks for your advice.


Ubuntu server 7.04 amd64 (Host OS)
VMWare server
CentOS 5 (Guest OS)


On Internet browsing Just found follow:-

NMS on a VMWare
http://www.opennms.org/index.php/NMSVmwareImage

Put together a VMWare Image which includes a ready-to-roll OpenNMS Installation.


Have you had any idea whether it is similar to "CentOS 5 images"? I just download

CentOS 5 images zip file on;
http://dev.centos.org/~tru/vmware/centos-5/


decompress it as images. Start VMWare server console. Create a link to the images then I can run "CentOS 5" on VMWare server immediately without going through all steps to install the OS from source.


Advice would be appreciated. TIA
