Hi All, Want to implement service request trace using http plugin of logstash in JSON Array format.
Getting the following error when trying to parse the JSON array: error: :message=>"gsub mutation is only applicable for Strings, skipping", :field=>"message", :value=>nil, :level=>:debug, :file=>"logstash/filters/mutate.rb", :line=>"322", :method=>"gsub"} :message=>"Exception in filterworker", "exception"=>#<LogStash::ConfigurationError: Only String and Array types are splittable. field:message is of type = NilClass> My json array is : { "data": [ { "appName": "DemoApp", "appVersion": "1.1", "deviceId": "1234567", "deviceName": "moto e", "deviceOSVersion": "5.1", "packageName": "com.tcs.DemoApp", "message": "testing null pointer exception", "errorLog": "null pointer exception" }, { "appName": "DemoApp", "appVersion": "1.1", "deviceId": "1234567", "deviceName": "moto e", "deviceOSVersion": "5.1", "packageName": "com.tcs.DemoApp", "message": "testing illegal state exception", "errorLog": "illegal state exception" } ] } my logstash config is : input { http { codec => "json" } } filter{ json { source => "message" } mutate { gsub => [ "message", "},\r\n\r\n{", "}shr{" ] } split { terminator => "shr" } } } output { stdout { codec => "json" } gelf{ host => localhost facility => "%{type}" level =>["%{SeverityLevel}", "INFO"] codec => "json" } file{ path => "/chroot/result.log" } } Any help would be appreciated. -- You received this message because you are subscribed to the Google Groups "Graylog Users" group.
