Hello,
First of all I discover ELK a bit late but I am very enthusiastic about these products.
I am starting to play with it but I face a weird issue : impossible to do a simple if / else
in my logstash filter
block.
I try to split grok filters between different log streams coming from docker containers. All my log events contains the docker.image
field, I plan to use it for that.
filter { if [docker.image] == "nginx:1.9" { mutate { add_field => { "matched" => "nginx" } } } else { mutate { add_field => { "matched" => "no" } } } }
No matter how I do this if
, all my logs have the field matched
set to no
. I tried with if [docker.image]
, if ["docker.image"]
, if [docker\.image]
.
I bet this is something simple but I can't figure it out. Any hint ?
Best regards,
Karim
