countryCode Client ISO alpha-2 country code. "ca"
host In this order of precedence: host name from the request line, or host name from the “Host” request header field, or the server name matching a request. Nginx $host variable. 192.168.0.103
listenerPort Port of the server which accepted a request. Nginx$server_port variable. "80"
request.httpVersion Request protocol, usually “HTTP/1.0”, “HTTP/1.1”, or “HTTP/2.0”. Nginx $server_protocol variable. "HTTP/1.1"
request.id Unique request identifier generated from 16 random bytes, in hexadecimal. Nginx$request_id variable. "f8860949459e94181e650d4049615a01"
request.method Request method, usually “GET” or “POST”. Nginx $request_method variable. “GET”
request.path Full original request URI (with arguments). Nginx $request_uri variable. "/console/css/%252e%252e%252fconsole.portal"
requestProtection.matchedData Data that triggered rule actions when the request was inspected. The string contains rule names that are separated by a semicolon. 'Test_data_1;Test_data_2;Test_data_3'
requestProtection.matchedIds String containing matched protection rule IDs and versions (for request inspection). When reporting, IDs are appended by 3 version symbols, so ID=123 and version=4 is reported as 123004. Entries are separated by a semicolon. "9301000_v001;9301100_v001;9301100_v001;9300000_v001"
requestProtection.matchedRules Rule names of request protection rules that matched when the request was inspected. The string contains rule names that are separated by a semicolon. 'Rule_name_1;Rule_name_2;Rule_name_3'
responseProtection.matchedData Data that triggered rule actions (in the response inspection). String containing rule names that are separated by semicolon. 'Test_data_1;Test_data_2;Test_data_3'
response.code Final response code sent to client. Nginx $status variable. "401"
response.size Full response size (headers + body) in bytes. Nginx $bytes_sent variable. "139"
requestAccessControl.matchedRules Rule names of request access rules that have matched. Strings contain rule names that are separated by a semicolon. 'Rule_name_1;Rule_name_2;Rule_name_3'
responseAccessControl.matchedRules Rule names of response access rules that have matched. Strings contain rule names that are separated by a semicolon. 'Rule_name_1;Rule_name_2;Rule_name_3'
backendStatusCode Keeps a status code of the response obtained from the upstream server. Status codes of several responses are separated by commas and colons. This is an Nginx$upstream_status variable. "200"
responseProtection.matchedIds String containing matched protection rule IDs and versions (for request inspection). When reporting, IDs are appended by 3 version symbols, so ID=123 and version=4 is reported as 123004. Entries are separated by a semicolon. '300_v004;25_v002;123_v001'
responseProtection.matchedRules Rule names of response protection rules that have matched. Strings containing rule names that are separated by a semicolon, for example: 'Rule name 1;Rule name 2;Rule name 3'. "Recomended Rules"
requestRateLimiting.matchedRules Rule names of rate limiter rules that have matched. String containing rule names that are separated by a semicolon. 'Rule_name_1;Rule_name_2;Rule_name_3'.
responseProvider
Contains information regarding where the response originates:
  • From backend (origin).
  • From some WAF module (module and rule name).
  • From LB HTTP IP access rule.
  • From LB HTTP method access rule.
  • From LB redirect rule.
 "requestProtection/Recomended Rules"
timestamp ES timestamp of when the request was received, local time in the ISO 8601 format. "2021-12-02T08:39:05Z"
