In the example below, munin-limits? will send a warning if the number of pending packages is higher than (or, although improbable, lower than) 0 packages.

# munin-run apt config
graph_title Pending packages
graph no
pending.label pending
pending.warning 0:0
hold.label hold

Other values

To send a warning if the read value is below a given number, this munin.conf example - borrowed from a busy mail system which should never see no mails coming through - could be useful:

    postfix_mailstats.delivered.warning 1:
