Improved cgroups information collection when mounted in a different location
When using Logstash within a container the cgroups information was mounted in a different location causing Logstash to not collect the information (#6797). A similar issue was affecting other parts of the stack so a fix has been merged to Logstash (#9999) that applies the same strategy as implemented in Elasticsearch (#22757) and beats (#3692).
Improved compliance to CEF spec with new "reverse_mapping" option
Currently, the Logstash cef codec, when decoding a payload, will use as keys the long name form of the CEF specification fields. However, this same spec advises that the short form should be used instead. A new boolean option called "reverse_mapping" has been introduced (PR #51) to perform this conversion. This option is disabled by default as it would introduce a breaking change but will very likely be flipped in the next major version of Logstash.
- Make cgroups more robust and provide the override similar to ES #9999
