proxy_ip |
The IP on the connection, i.e. a proxy IP if the request has been proxied |
request_end |
The time the request was returned in ms since unix epoch |
status_code |
The HTTP status returned to the client |
handling_instance |
The product instance name the request was forwarded to |
handling_server |
The allocator IP address the request was forwarded to |
request_length |
The length of the request body, a value of -1 means streaming/continuing |
request_path |
The request path from the url |
instance_capacity |
The total capacity of the handling instance |
response_time |
The total time taken for the request in milliseconds ms. response_time includes backend_response_time. |
backend_response_time |
The total time spent processing the upstream request with the backend instance ({{es}}, {{kib}}, and so on), including the initial connection, time the component is processing the request, and time streaming the response back to the calling client. The proxy latency is backend_response_time - response_time. backend_response_time minus backend_response_body_time indicates the time spent making the initial connection to the backend instance as well as the time for the backend instance to actually process the request. backend_response_time includes backend_response_body_time. |
backend_response_body_time |
The total time spent streaming the response from the backend instance to the calling client. |
auth_user |
The authenticated user for the request (only supported for basic authentication) |
capacity |
The total capacity of the handling cluster |
request_host |
The Host header from the request |
client_ip |
The client IP for the request (may differ from proxy ip if X-Forwarded-For or proxy protocol is configured) |
availability_zones |
The number of availability zones supported by the target cluster |
response_length |
The number of bytes written in the response body |
connection_id |
A unique ID represented a single client connection, multiple requests may use a single connection |
status_reason |
An optional reason to explain the response code - e.g. BLOCKED_BY_TRAFFIC_FILTER |
request_start |
The time the request was received in milliseconds ms since unix epoch |
request_port |
The port used for the request |
request_scheme |
The scheme (HTTP/HTTPS) used for the request |
message |
An optional message associated with a proxy error |
action |
The type of elasticsearch request (e.g. search/bulk etc) |
handling_cluster |
The cluster the request was forwarded to |
request_id |
A unique ID for each request (returned on the response as X-Cloud-Request-Id - can be used to correlate client requests with proxy logs) |
tls_version |
A code indicating the TLS version used for the request - 1.0 769,1.1 770,1.2 771,1.3 772 |
instance_count |
The number of instances in the target cluster |
cluster_type |
The type of cluster the request was routed to (e.g. {{es}}, {{kib}}, APM) |
request_method |
The HTTP method for the request |
backend_connection_id |
A unique ID for the upstream request to the product, the proxy maintains connection pools so this should be re-used |
