We will want to monitor liberty, to make sure everything is working properly, and have it alert [[ServerPeople][us]] if that's not the case. ---++ Internal monitoring Both the hardware and the software have the capability to check and report on various conditions. We should make use of this, and send mail if things are out-of-range. Things to monitor this way might include: * Load average * Free disk space * Temperature and fan speed * Hard disk health (SMART) * RAID status * Unusual firewall/service activity ---++ External monitoring We also want some monitoring done externally -- that is, running on computers *other* than liberty. For one, to really be sure everything is working, you need to check things from off the system. More importantly, a really serious problem (kernel crash, power loss, network down, etc.) will prevent liberty from notifing us in the first place. Things we might want to monitor this way: * ping response * TCP response (simple "Can I connect?" probes) * SMTP banner (connect, make sure you get the proper identification) * HTTP page request (make sure we can fetch some known URL) * SMTP mail flow (will mail forwarded through the system make it to the other end?) ---+++ Monitoring hosts Anyone doing any external monitoring, please record your IP address and host name, and what you're monitoring: * 192.0.2.69 - somebox.example.com * ping * TCP probes of HTTP, SSH, SMTP * requesting www.gnhlug.org home page * Bill's Intermapper on adelphia * ping * TCP probes of HTTP, SSH, SMTP, HTTPS, DNS
