Adviced filesystem sizes for nagiosxi server

[junkertf]

Hello,

We had some incident about the filesystem sizes of our prod nagiosXi server.

Regarding that i want ask that what FS sizes is adviced for a NagiosXi server for 1000 hosts and over 10k services?

Currently we have the following sizes:

Filesystem Size Used Avail Use% Mounted on
/dev/mapper/vgsystem-lvroot 2.0G 399M 1.5G 22% /
/dev/mapper/vgsystem-lvusr 4.9G 2.5G 2.2G 54% /usr
/dev/sda1 488M 108M 345M 24% /boot
/dev/mapper/vgsystem-lvvar 15G 3.2G 11G 23% /var
/dev/mapper/vgsystem-lvtmp 2.0G 39M 1.8G 3% /tmp
/dev/mapper/vgsystem-lvhome 976M 2.8M 906M 1% /home
/dev/mapper/vgsystem-lvopt 2.0G 388M 1.5G 22% /opt
/dev/mapper/vgsystem-lvapp 148G 22G 119G 16% /app

Here are the specs for a system that doesn't have the partitions you have

https://assets.nagios.com/downloads/nag ... ements.pdf

So you would be looking at wanting total space of around 500GB

In a standard install the bulk of the data ends up being split between the following directories

Code: Select all

/usr
/var
/store

Thank you!

I had found that spec also, but need a bit more detailed spec to split the FS sizes.
Acutally the application use the /app FS to store application related files, so way that /usr/local/nagios* is linked to under /app.
Also the mentioned /store is located (linked from) here under the /app FS.

Only the /var is separated to other FS from /app.

So way can you give me a bit more detailed spec how i that two FS size?

Thanks, Best regards,

I would give /app about 40%, /var 30% and / 30% which (will pick up /store where backups are held).

But this is a bit of a guess because every installation and setup is different.
