%W Trap description

%q Trap sub-type (numeric, in decimal)

%P Security information from the PDU (community name

for v1/v2c, user and context for v3)

%v list of trap's variables

In addition to these values, you may also specify an

optional field width and precision, just as in printf, and

a flag value. The following flags are legal:

- left justify

0 use leading zeros

# use alternate form

The "use alternate form" flag changes the behavior of some

format flags. Normally, the fields that display time

information base it on the local time, but this flag tells

them to use GMT instead. Also, the variable list is nor

mally a tab-separated list, but this flag changes it to a

comma-separated one. The alternate form for the uptime is

similar to "3 days, 0:14:34.65"

Examples:

To get a message like "14:03 TRAP3.1 from humpty.ucd.edu"

you could use something like this:

snmptrapd -P -F "%02.2h:%02.2j TRAP%w.%q from %A\n"

If you want the same thing but in GMT rather than local

time, use

snmptrapd -P -F "%#02.2h:%#02.2j TRAP%w.%q from

%A\n"
