Testing nagios log server

[fsodah]

I am in the process evaluating nagios log server comparing with other products.
I did the setup working perfectly, however how can I sniff for example all logs from my linux server under /var/log/, can you please give me a sample rsyslog.conf that capture all logs under linux, I am attaching my rsyslog.conf from a linux machine the one I am using now

Code: Select all

root@kali:/etc# more rsyslog.conf
# /etc/rsyslog.conf configuration file for rsyslog
#
# For more information install rsyslog-doc and see
# /usr/share/doc/rsyslog-doc/html/configuration/index.html

I would recommend using the setup-linux.sh script to send over the logs. This will create the proper rsyslog configuration under /etc/rsyslog.d/. It can be found on the NLS server by pointing your browser to http://nls-ip/nagioslogserver/configure ... inux-files.

I wouldn't recommend sending over all logs found here with a single configuration. The logs will have different formats and using separate configurations will allow you to add additional filtering easier if it is needed.

For example, I would run the script twice if I wanted to see both auth and boot logs in NLS:

Code: Select all

sudo bash setup-linux.sh -s 192.168.55.3 -p 5544 -f "/var/log/auth.log" -t auth_logs
sudo bash setup-linux.sh -s 192.168.55.3 -p 5544 -f "/var/log/boot.log" -t boot_logs
