Could anyone help me with the reason why logstash doesn't parse Laraver logs, please? Where is the core problem?

Interesting that access logs and some errors log are parsed well. I can't understand why Laravel access logs are parsed normally, also.

My logstash.conf

```auto
input {
        gelf {
        port => "${X_PORT}"
        type => gelf
   }
}

# Laravel errors are being delivered with the backslashes that cannot be processed by Logstash, therefore, they should be removed/replaced
filter {
  if "_jsonparsefailure" in [tags] {
    mutate {
      gsub => ["message", "[\\]", "/"]
    }
    mutate {
      add_field => { "[@metadata][X_STAGE]" => "${X_STAGE}" }
      add_field => { "[@metadata][X_PROD]" => "${X_PROD}" }
    }
    dissect {
      mapping => {
        "message" => "%{error}"
      }
    }

        if [source_host] == [@metadata][X_STAGE] {
          mutate { add_field => { "[@metadata][target_index]" => "laravel-x-stage" } }
        }
        else if [source_host] == [@metadata][X_PROD] {
          mutate { add_field => { "[@metadata][target_index]" => "laravel-x-prod" } }
        }
  }
}

# All logs from Laravel come with the tag "logstash-%{[tag]}", therefore, it is needed to filter them according to the source received
filter {
  if [type] == "Laravel" {

    mutate {
       add_field => { "[@metadata][X_STAGE]" => "${X_STAGE}" }
       add_field => { "[@metadata][X_PROD]" => "${X_PROD}" }
    }
    if [source_host] == [@metadata][X_STAGE] {
      mutate { add_field => { "[@metadata][target_index]" => "laravel-x-stage" } }
    }
    else if [source_host] == [@metadata][X_PROD] {
      mutate { add_field => { "[@metadata][target_index]" => "laravel-x-prod" } }
    }
  }
}

# Filtering of logs received from Nginx
filter {
  if [tag] == "nginx-x-prod" or [tag] == "nginx-x-stage" {
    dissect {
      mapping => {
        "message" => "%{time}; %{client-ip}; %{method}; %{request}; %{request_length}; %{status}; %{bytes_sent}; %{referer}; %{user_agent}.; %{upstream_addr}; %{upstream_status}; %{request_time}"
      }
    }
  }

output {
  if [tag] == "proxy-prod" {
    opensearch {
      hosts => ["${OPENSEARCH_HOST}"]
      ssl => false
      ssl_certificate_verification => false
      user => "${LOGSTASH_USER}"
      password => "${LOGSTASH_PASS}"
      index => "proxy-x-%{+YYYY.MM}"
    }
  }
  else {
    opensearch {
      hosts => ["${OPENSEARCH_HOST}"]
      ssl => false
      ssl_certificate_verification => false
      user => "${LOGSTASH_USER}"
      password => "${LOGSTASH_PASS}"
      index => "%{[@metadata][target_index]}-%{+YYYY.MM}"
    }
    opensearch {
      hosts => ["${OPENSEARCH_HOST}"]
      ssl => false
      ssl_certificate_verification => false
      user => "${LOGSTASH_USER}"
      password => "${LOGSTASH_PASS}"
      index => "%{[tag]}-%{+YYYY.MM}"
    }
  }
}

```

But, I still see this:

I tried to use JSON filter, but it's still not working ☹

```auto
filter {
  if "_jsonparsefailure" in [tags] {
# mutate {
# gsub => ["message", "[\\]", "/"]
# }
    json { source => "message" remove_field => ["message"] target => "[someField]" }
    json { source => "[someField][0][log]" target => "[someField][0][stuff]" }
    mutate {
      add_field => { "[@metadata][X_STAGE]" => "${X_STAGE}" }
      add_field => { "[@metadata][X_PROD]" => "${X_PROD}" }
    }
# dissect {
# mapping => {
# "message" => "%{error}"
# }
# }

        if [source_host] == [@metadata][X_STAGE] {
          mutate { add_field => { "[@metadata][target_index]" => "laravel-x-stage" } }
        }
        else if [source_host] == [@metadata][X_PROD] {
          mutate { add_field => { "[@metadata][target_index]" => "laravel-x-prod" } }
        }
  }
}

```

Can you put a textual log sample? Few lines.

Can you dump a raw gelf message? Without filter or from log files?  
Who provides/generates \_jsonparsefailure ?

Yeah, above I sent raw gelf message this log.  
The system works as follows :  
Laravel forms logs using the default library for logstash logs. After it, these logs have been sent from Laravel docker\_container to logstash docker\_container.

Probably the following logs may help you?

I see here a multiline pattern:  
[2022-11-24 16:40:26] local.ERROR: This field is required. (and 2 more errors) {"exception":{"code":0,"file":"/var/www/html/vendor/laravel/framework/src/Illuminate/Foundation/Http/FormRequest.php:144","message":"This field is required. (and 2 more

[**datetime**] **loglevel** : **msg** { **details**...

Are these fields OK?

Could you help with this, please?  
And would you mind if tell me how you were able to see this pattern, please?

If you need any additional info, let me know, please
