Nagios Support Forum

I have recently downloaded the 64-bit CentOS - NagiosXI VMWare Virtual Machine and noticed it was quite small in size. I was wondering if Nagios had any recommendations
for disk size, memory requirements, for a production system. I have modified the VMWare image to use 4GB of RAM, and upgraded the NIC driver to the VMXNET3 driver as it provides better performance than the flexible driver, however I noticed it has a rather small disk of like 8GB for the (/) partition.

So in short I guess my question is what is the best method assuming we are going to continue using NagiosXI and plan to monitor anywhere from 250-500 hosts, with a few thousand services? Should i just install a VM from scratch and install the software via Source code? or just modify the VM provided and move Postgres and some other directions to a new partition?

Thanks much for your advise? Also is it possible to backup/restore all the configuration from one nagiosXI instance to a new one later down the road?

Whatever you decide to do, keep in mind that hard drives fill in fast. We've seen it way too often, when customers run out of disk space, because they didn't think ahead. If you run out of space, this can cause a database corruption, which is something you what to avoid...

Hope this helps!
