Here's what I'm using with dwm - probably good for dzen as well:
dwm-mystats.sh
#!/bin/zsh
# vim:ft=zsh ts=4

# Date format as recognized by standard system 'date'
SDATE_FORMAT='%Y-%m-%d %H:%M'
sdate() {
date +${SDATE_FORMAT}
sdfree() {
print -n `df -h / /home` | awk '{verf1=$11; part1=$13; verf2=$17; part2=$19}; END {print "["part1"] -"verf1" [~] -"verf2}'
smemused() {
awk '/MemTotal/ {t=$2}; /MemFree/ {f=$2}; END {print t-f " " t}' /proc/meminfo | dbar -w 6 -s '='
swapused() {
awk '/SwapTotal/ {t=$2}; /SwapFree/ {f=$2}; END {print t-f " " t}' /proc/meminfo | dbar -w 6 -s '='
sload() {
print -n ${(@)$(</proc/loadavg)[1,3]}
scpu() {
vmstat | awk '/0/ {print 100-$15}' | dbar -w 6 -s '='
snetabs() {

if [ $iface != "" ] ; then
print -n "$iface: `mesure -l -i $iface -avK -c 2`||"
fi
snetbar() {
mesure -aK -c 2 -l -i `ifconfig | grep "Ethernet" | awk '{print $1}'` | dbar -nonl -w 6 -s '=' -min 0 -max 270
sac() {

print -n "no"

sbatt() {

You can play around a bit with the functions that get called/displayed in the main loop. It depends on zsh and makes use of this cronjob (in /etc/cron.hourly/pacsync):
#!/bin/dash
pacman -Syup --noprogressbar > /var/log/updates.log
