Lab46 Wiki

monitor.offbyone.lan runs Zabbix, a distributed monitoring system.

monitor.offbyone.lan created on yourmambas on 10/29/2010. Created using the same methods I used to create lab46, irc, and db.

• Created monitor.offbyone.lan, updated DNS and DHCP on caprisun.

• offload MySQL to db.offbyone.lan
• look into offloading web-server related stuff to www.offbyone.lan (if possible)
• basically, look for ways to reduce overall memory usage (disk is not a problem, we could add more if need be)

The Xen config file for this VM is as follows:
