below is my logstash.config file

input {
          file {
                path => "/Users/znrind-a0053/Downloads/logs/app-info.log"
                start_position => "beginning"
                sincedb_path => "/dev/null"
          }
    }
    filter {
          grok {
          separate => " "
          pattern => "%{TIMESTAMP_ISO8601:timestamp} %{AUDITLOGLEVEL:level} %{PROG:program} %{GREEDYDATA:message}"
          }
    }
    output {
            elasticsearch {
                hosts => "localhost"
                index => "logs"
                document_type => "collected_logs"
            }
            stdout{}
    }

Any help is appreciated. Thanks in advance.

There should be a more specific error message immediately preceding this. grok does not have a "separate" option, so try removing that.

Thank you for the solution. I modified the config file as per your comments it worked

input {
file {
path => "/Users/znrind-a0053/Downloads/logs/app-info.log"
start_position => "beginning"
sincedb_path => "/Users/znrind-a0053/Documents/elasticsearch/el_logs/elfile"
}
}
filter {
grok {
match => {"messages" => "%{DATESTAMP_EVENTLOG:timestamp}%{SPACE}%{LOGLEVEL:log_level}%{SPACE}%{WORD:method}%{SPACE}%{WORD:class_name}%{SPACE}%{GREEDYDATA:log_message}"}
}
}
output {

stdout{}
