How to blacklist events from monitored logs


I have 3 different event types :

2017-02-08T08:55:32,704 [host;app1;http-bio-8115-exec-5;[[xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx] (git:stuff) text                                                       WARN  -  message1
2017-02-08T08:55:30,262 [host;app2; Pitt][generic][T#1];[[xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx] (git:stuff) text                                              WARN  -  message2
2017-02-08T08:55:29,227 [host;app3;AsyncTaskExecutor-10;[[xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx] (git:stuff) text                                                        WARN  -  message3

inputs.conf contains

disabled = false
sourcetype = log4j
blacklist = /\S[WARN]/g

Events still get indexed. Please help with some direction.

Thank you in advance.

Re: How to blacklist events from monitored logs


The blacklist attribute in a monitor stanza acts against files within the path and not individual events within a file. The inputs.conf documentation states

blacklist =
* If set, files from this input are NOT monitored if their path matches the specified regex.

To filter at the event level for a file monitor you can add settings to the props.conf and transforms.conf. It's documented here
