My upgrade process for several full jails on a host:

for jail in $(jls name); do
echo "=== Updating jail: $jail ==="
jexec $jail freebsd-update fetch install
jexec $jail pkg upgrade -y
done

service jail restart

Works, gets the job done and is "good enough".

#freebsd #jails #automation #shell

Got #FreeBSD? Got #jails on FreeBSD?

Ever wonder how much resources a given jail consumes?

#LibreNMS has something for that: OS Level Virtualization

It's a FreeBSD port at net-mgmt/p5-OSLV-Monitor

Look at the following, which is testing database dumps to make sure they load. It is titled: CPU/System/User Time in secs/sec

New post: FreeBSD resource monitoring and accounting.

A practical tour of the base-system toolkit for figuring out *what is actually using my server*: top, vmstat, systat, gstat, netstat/sockstat, procstat, pfctl, and per-jail attribution with kern.racct and rctl.

No ports, no agents. Just FreeBSD.
