<div dir="ltr"><div><div><div><div>Hi,<br><br></div>Thanks for the compliments :) Right now syslog-ng doesn't really support arrays, although we had plans about those in the past, but nothing concrete yet.<br><br></div>
syslog-ng has builtin support for tags (e.g. the tags() option for various sources and the db-parser()/patterndb configuration files), but those can also be limited a bit. Can you elaborate about your usecase? What part of your setup would associate the tags with the message?<br>
<br></div>To add arrays to syslog-ng, one would need to add the appropriate logic to $(format-json), we've figured that the flat name-value pairs structure of syslog-ng would simply be formatted to be an array. Given the following set of name-value pairs:<br>
<br></div><div>tags[0] = 'foo'<br></div><div>tags[1] = 'bar'<br></div><div>tags[2] = 'baz'<br><br>Would become an array automatically, when formatted via format-json, e.g.<br><br></div><div>tags = [ "foo", "bar", "baz" ]<br>
</div><div><br>The only part missing is basically the recognition that a specific name has brackets at the end and sorting the elements properly. (right now we iterate in alphabetical order, which wouldn't work with numerical indices).<br>
<br></div><div>Once this is in place, we would only need to add some rewrite operations to "append"/"pop" on an existing array.<br><br></div><div>Such a contribution would be absolutely appreciated.<br>

<div><br></div><div>My question is about adding an array to a JSON document. What I'm trying to do is to send a message like this:</div>
<div><br></div><div>@cee: {"message": "test message", "tags":["test", "message"]}</div><div><br></div><div>My template looks a like this:</div><div><br></div><div>template("@cee: $(format-json --pair message=\"$MSG\" --pair tags="test")\n")<br>
</div><div><br></div><div>This works fine for a single tag, but how can I add multiple ones?</div><div><br></div><div>The broader use-case is that I want to add tags to logs matching a specific filter. For example:</div>
<div>
----------------------</div><div><div>filter user_tests { facility(user) and message(test) };</div><div><br></div><div>destination logsene_tests {</div><div> syslog("<a href="http://logsene-receiver-syslog.sematext.com" target="_blank">logsene-receiver-syslog.sematext.com</a>"</div>
<div> transport("tcp")</div><div> port(514)</div><div> template("@cee: $(format-json --pair message=\"$MSG\" --pair tags=\"test\")\n")<br></div><div> );</div><div>
};</div></div><div><br></div><div>log { source(all_syslog); filter(user_tests); destination(logsene_tests); flags(final); };<br></div><div><div>----------------------</div><div></div></div><div><br></div><div>If there's a better way to add multiple tags to a log, please tell me - I'm good with making big changes if it leads to a cleaner/better config.</div>
