I'll dig around in the ommongodb output plugin in the meantime and see
what I can learn - I know that one was updated recently so it's probably
a good one to reread. Thanks!

Hi Radu! Thanks for the link, but I already know how to work with list
templates from a conf perspective. I'm looking for good examples of
accessing that data from code in an output plugin. Currently my plugin
simply does this in CODESTARTdoAction:
CHKiRet(writeHiredis(ppString[**0], pData));
This passes the entire output from the template as a string to redis.
This works ok when I want to construct redis commands from templates using
individual properties straight to hiredis's redisAppendCommand function,
such as:
"HINCR progcount %programname% 1"
But it does not work when I want to send whole messages to redis
(whitespace in the syslog message be interpreted as delimiters in the
command, causing errors).
hiredis has another function however, redisAppendCommandArgv, that is
variatic. In order to use this I would like to construct a list using the
list templates, and then access each individual member of the list from the
output plugin code so I can construct the array to pass to
redisAppendCommandArgv. So, let's say I construct the following template:
template(name="redisPushQueue" type="list") {
constant(value="LPUSH")
constant(value="queue_key")
property(name="msg")
}
From the output plugin code, how do I then access each member of this list
individually with the new template code?
Make sense?

Hello Brian,
Just to make sure we're not missing the obvious:

Besides that, there are a couple of examples here:

I've been working on some improvements for the omhiredis output plugin
this
week. I think I've come up with a better way of combining templates with
redis command formatting. In order to do this, I need to, given a list
style template, get the number of elements in the list and the length of
each element.
I've only worked with string templates (from a plugin perspective) with
my
output plugins so far. Is there a good example somewhere for dealing
with
list templates?
On other fronts, I now omhiredis working with batch dequeue in
conjunction
with hiredis' pipeline commands. In local tests this let me push around
250,000 redis commands per second to a redis instance (I was getting
around
50k commands of the same type with the same test before the changes).
Rainer - I'm hoping to wrap up this next round of improvements in a few
days and get a patch your way!
Brian
