This is a quick Install How to Guide on How to install NSTI NSTI is the Nagios  SNMP Trap Interface. If you setup your Nagios to receive passive SNMP Traps, you did this most likely via snmptt then you have the option to store the SNMP traps in the MySQL Database. Due to the lack of Nagios to show only the last incoming trap there is no way (except of sending notifications via mail) to list all the incoming traps. Well now there is. NSTI You could find a few details about NSTI here http://exchange.nagios.org/directory/Addons/SNMP/Nagios-SNMP-Trap-Interface-%28NSTI%29/details Or in the Support Forum http://support.nagios.com/forum/viewforum.php?f=22 There is a Version 2.0 RC of which I would strongly advise to stay away simply cause it didn’t work. http://labs.nagios.com/2012/01/10/nagios-snmp-trap-interface-nsti-available/ So how do we install it.

(load of 40.x and I have no idea why) In general unless there are very good reasons for portability, security or snapshot features, I’m more a fan of Containers (OpenVZ or Zones for Solaris). They are simply more performant and don’t have that overhead KVM virtualization brings with. However one negative side-effect of Openvz is for example IPtables. IPtables under openVZ are a nightmare. When you know what you do, you secure the container from the Host and wont need IPtables on the CT. But my problem was that NagiosXI needs (kind of) Iptables for its automated install script. So I had to work around anbit to get it running on the CT and know what .. […]
