Cannot load an invalid configuration in logstash.conf


(Aarish Ramesh) #1

I am trying to configure logstash for the following inputs - nginx access, nginx error & logs following a custom pattern & below is the logstash.conf

input {
    beats {
    port => 5044

codec => multiline {
  # Grok pattern names are valid! :)
  pattern => "^%{TIMESTAMP_ISO8601} "
  negate => true
  what => previous
    }
}
}

filter {

if [type] == "nginx-access" {
    grok {
    match => [ "message" , "%{COMBINEDAPACHELOG}+%{GREEDYDATA:extra_fields}"]
    overwrite => [ "message" ]
    }

    mutate {
            convert => ["response", "integer"]
            convert => ["bytes", "integer"]
            convert => ["responsetime", "float"]
    }

    geoip {
            source => "clientip"
            target => "geoip"
            add_tag => [ "nginx-geoip" ]
    }
      
    date {
            match => [ "timestamp" , "dd/MMM/YYYY:HH:mm:ss Z" ]
            remove_field => [ "timestamp" ]
    }
 
    useragent { 
            source => "agent"
    }

}  else if [type] == "nginx-error" { 
    grok {
    match => [ "message" , "(?<timestamp>%{YEAR}[./-]%{MONTHNUM}[./-]%{MONTHDAY}[- 
]%{TIME}) \[%{LOGLEVEL:severity}\] %{POSINT:pid}#%{NUMBER}: %
{GREEDYDATA:errormessage}(?:, client: (?<client>%{IP}|%{HOSTNAME}))(?:, server: %
{IPORHOST:server})(?:, request: %{QS:request})?(?:, upstream: \"%{URI:upstream}\")?(?:, host: 
%
{QS:host})?(?:, referrer: \"%{URI:referrer}\")"] 
    overwrite => [ "message" ]
    }

geoip {
            source => "client"
            target => "geoip"
            add_tag => [ "nginx-geoip" ]
    }

    date {
            match => [ "timestamp" , "YYYY/MM/dd HH:mm:ss" ]
            remove_field => [ "timestamp" ]
    }

} else {

  mutate {
  gsub => ["message", "\n", " "]
}
  grok {
match => [ "message", "%{TIMESTAMP_ISO8601:timestamp} \[%{NOTSPACE:uid}\] \[%
{NOTSPACE:thread}\] %{LOGLEVEL:loglevel} %{DATA:class}\-%{GREEDYDATA:message}" ]
overwrite => [ "message" ]
}
date {
match => [ "timestamp" , "yyyy-MM-dd HH:mm:ss" ]
target => "@timestamp"
}
if "_grokparsefailure" in [tags] {
         drop { }
}
}
}

output {

stdout { codec => rubydebug }
if [type] == "nginx-access" {
 elasticsearch { hosts => localhost }
 index => "nginx-access-%{+YYYY.MM.dd}"
} else if [type] == "nginx-error" {
 elasticsearch { hosts => localhost }
index => "nginx-error-%{+YYYY.MM.dd}"
} else {
 elasticsearch { hosts => localhost }
}

}

But on running it, I get the following error

ERROR logstash.agent - Cannot load an invalid configuration {:reason=>"Expected one of #, {
at line 84, column 9 (byte 1883) after output {\n \nstdout { codec => rubydebug }\nif [type] ==
"nginx-access" {\n elasticsearch { hosts => localhost }\n index "}

I am not sure what the error is. Can someone help me figure it out ?


#2

elasticsearch { hosts => localhost }
index => "nginx-access-%{+YYYY.MM.dd}"

Try:

elasticsearch { 
  hosts => ["localhost:9200"]  (or another port depending of your conf)
  index => "nginx-access-%{+YYYY.MM.dd}"
}

Index shall be in elasticsearch object, not outside
