      Thanks for your reply and provide the solution, is there any way to do the same on LTM Policy because we are migrating irule to policy, in irule traffic logs mentioned as below in the current configuration.


      when HTTP_REQUEST {

      #log local0. "Host: [HTTP::host], URI: [HTTP::uri]"
      # HTTP::header insert X-SSL-SECURE "true"
      # HTTP::header insert "X-FRAME-OPTIONS" "DENY"
      log local0. "Request HOST is [HTTP::host] URI is [HTTP::uri]"
      HTTP::header insert X-Forwarded-For [IP::client_addr]
      #HTTP::header insert X-SSL-SECURE "true"
      # Disable the stream filter for all requests
      # LTM does not uncompress response content, so if the server has compression enabled
      # and it cannot be disabled on the server, we can prevent the server from
      # sending a compressed response by removing the compression offerings from the client
      HTTP::header remove "Accept-Encoding"
      if {[string tolower [HTTP::host]] starts_with ""} {
      log local0. "Host starts_with"
      switch -glob [string tolower [HTTP::uri]] {

      "/searchclaimservice*" { pool /UAT_ISA/Tstacmepreprodocr }
      "/androidservice*" { pool /UAT_ISA/Tstacmepreprodocr }
      "/documentsviewe*" { pool /UAT_ISA/Tstacmestgjboss }
      "/claimsejb*" { pool /UAT_ISA/Tstacmestgjboss }
      "/*" { pool /UAT_ISA/Tstacmeliferay }

      is there any option to enable the local traffic logs via ltm policy

        Hi Vadivelan,

        I try to check F5 article but not found any information about local traffic policy can print access logs,

        Could you please create only irule for access logs and use another function on local traffic policy
