@ -6,9 +6,9 @@ analyzer-d4-log relies on redis to consume grokked loglines.
|
|||
|
||||
To grok the loglines, analyzer-d4-log relies on an external tool: both logstash https://www.elastic.co/logstash
|
||||
and nifi https://nifi.apache.org/ have been tested for this purpose (using this nifi template https://github.com/D4-project/d4-nifi-templates).
|
||||
These tools poll directly the d4 server'redis server for loglines and push the results into a specific redis queue that the analyzer consumes.

analyzer-d4-log polls this queue periodically to produce counts and statistics of the data. At the moment, only sshd logs are supported but more will come in the future.
