Nagios Log Server on RHEL 6

[krobertson71]

Just curious... your Primary size for your cluster is 287mb but when you look at /usr your /usr/local is 695m... where is the extra data coming from? Also noticed /usr/share was 290ish...

Just trying to understand for sizing.
.5
EDIT: I was just looking at mine and my /usr/share is 294m as well so must be from initial install as my cluster is only 5.5mb in size. Is all this extra 695 for /usr/local and 294 for /usr/share just part of the initial install or is there space set aside for the cluster/indexes to collect data into? If that make sense. Like you can make a db 100gb and the file will take that much space on the HD but the database itself may only have 100mb in it.. Hope that clarifies my question.

By default du actually lists block counts, not size, hence the -h flag. However that doesn't appear to translate to actual byte size as we really would like them. You should instead look at using the --apparent-size flag, which does appear to display correctly as it uses the size that would be transferred not ondisk size.

[root@localhost libexec]# du -sh /

Code: Select all

5.7G    /

[root@localhost libexec]# du -sh --apparent-size /

Code: Select all

9.8G    /

[root@localhost libexec]# du -sh --apparent-size /*

Code: Select all

7.5M    /bin
21M     /boot
7.8K    /dev
97M     /etc
9.5K    /home
301M    /lib
24M     /lib64
16K     /lost+found
4.0K    /media
0       /misc
4.0K    /mnt
0       /net
8.0K    /opt
5.1G    /proc
83M     /root
34M     /sbin
4.0K    /selinux
4.0K    /srv
143M    /store
153M    /sys
56K     /tmp
3.2G    /usr
776M    /var

Those numbers look much more correct when adding /usr and /var to match /.

I installed Log Server on the "CentOS 6.5 x86_64 minimal" server. I think I have installed a few additional packages.

I believe /usr/share is all "system" stuff, docs-n-stuff for installed packages. I do not believe Nagios installs anything in there, but when we install system packages, they install quite a bit of stuff there. It should not grow much (if any) unless you add more packages.

Investigating /usr/local,

Code: Select all

[@LogServer-centos65-64bit local]$ du -sh *
8.0K    bin
4.0K    etc
4.0K    games
4.0K    include
4.0K    lib
4.0K    lib64
4.0K    libexec
522M    nagioslogserver
4.0K    sbin
92K     share
4.0K    src
178M    vmware

You can see I have added the vmware tools, that is a chunk of the "extra" space.

From digging around with my Log server, there are source files taking up and additional 212M.

That leaves the data files at about 311M. Which I would believe gives us about 5% overhead for the files/data .
