Here is my event's raw data:
{"line":"level=info t=\"2019-01-29T18:19:42.999Z\" rt=2 method=GET path=\"/contentskus/5b7ee52a4f6b9c001b049ac3?dma=999\u0026itemsPerPage=25\u0026page=1\" sc=200 dma=999 apikey=DEFAULT amzn_trace_id=unknown enabledFeatures=recommendations,upcomingSearch,popularityQueriesPlatformSpecific,availabilityTimes,avoidDefaultQuery,useFavoritesExternalSchemaForD2C,useFavoritesV2ForFavoritesFilter,endCardRecommendations,cmsAuthFallback os=2 rid=\"6962240ed296c770\" mode=published","source":"stdout","tag":"ecs-uat_admin_v1sandbox_blue-35-uat-service-admin-d8d0a7a0c2dfe8ea6c00/503343765eaa","attrs":{"SERVICE_NAME":"admin","SERVICE_TAGS":"contentgroups,contentsettings,contentskus,metatags,settings,userroles,users,s3signurl","SERVICE_VERSION":"v1sandbox","com.amazonaws.ecs.task-arn":"arn:aws:ecs:us-west-2:776609208984:task/305f6e5a-d20d-4aa2-877d-1bba2d442a7b"}}
I'm trying to create a new field called service_name where I extract the highlighted portion in the above event. The regukar expression that I wrote is: \W\W\W[e][c][s]\S(?\w{1,})
Achieved result: uat_admin_v1sandbox_blue
Expected result: admin_v1sandbox_blue
Please help!!!
