Nagios - setting up a new host

1. Location --> /usr/local/nagios/etc/objects/ --> Setup new host

(I normally just copy another setup)

2. sudo cp host.cfg newhost.cfg

3. Then you have to setup the new host in
/usr/local/nagios/nagios.cfg
/usr/local/nagios/etc/objects/hostgroups.cfg
/usr/local/nagios/etc/objects/templates.cfg

3.1 Install nsclient++ on the new server

4. verify the configuration
/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

5. Restart nagios
/etc/init.d/nagios restart

Yottabyte ~ 1 000 000 000 000 000 000 000 000 bytes



And the reasons for the names :
Kilo Greek khilioi = 1000
Mega Greek megas = great, e.g., Alexandros Megos
Giga Latin gigas = giant
Tera Greek teras = monster
Peta Greek pente = five, fifth prefix, peNta - N = peta
Exa Greek hex = six, sixth prefix, Hexa - H = exa
Remember, in standard French, the initial H is silent, so they would pronounce Hexa as Exa.
Zetta almost homonymic with Greek Zeta, but last letter of the Latin alphabet
Yotta almost homonymic with Greek iota, but penultimate letter of the Latin alphabet.

Splunk Indexes
When you add new data to Splunk it store it in an index

Indexes are stored here:

/opt/splunk/var/lib/splunk/

Splunk has been installed in:
/opt/splunk

To start Splunk, run the command:
/opt/splunk/bin/splunk start

To use the Splunk Web interface, point your browser at:
http://Your-SERVER:8000

SPlunk won't start after upgrade to 4.1.4
I ended up modifying the inputs.conf & indexes.conf to delete the references to splunklogger..
