[Lognorm] log classification with liblognorm

[Castillo, Jose Contractor]

Rainer,

I was able to get an extra field in the output file using "annotate" in the rule file, but when I use more than one tag in one rule rsyslog process die (Program terminated with signal 11, Segmentation fault).

I sent detailed information about this issue to rsyslog list (thread:  "log classification with lognorm issue")

Thanks in advance for any help.

Jose

David made me aware of this thread. Sorry for not responding further, I've been very busy and probably overlooked it. More inline...

David,

I modified the template:
template(name="testFormat" type="string" string="%$!all-json%,tag='%$!mytag%'")

I also modified the rule to include mytag as a tag:
rule=mytag:%date:word% %host:ipv4% : %%ASA-%number0:number%-%number1:number%: Denied ICMP type=%number2:number%, code=%number3:number% from %origin:ipv4% on interface outside

And now I getting :
{ "origin": "77.2.2.2", "number3": "0", "number2": "8", "number1": "313001", "number0": "3", "host": "0.0.0.0", "date": "2013-06-26T10:47:42+01:00" },tag=''

No tags are being written to the output file.

What am I doing wrong?

I need to check the code, but I think you are doing everything right. IIRC, tags were meant as classification method for rsyslog's engine (if-stmts). I think outputting them was not at the table when this was written. I am 90% sure, and will try to verify the rest within this week.

Thanks,

Jose

the tags are accessed in rsyslog by $!<tag name>

so where you would have done %hostname% you could do %$!mytag%
