Text of the page (random words):
ture none a fixed concurrency of 1 only one request can be outstanding at any given time default adaptive request headers optional object additional http headers to add to every http request request headers required string literal an http request header and its value both header names and values support templating with event data examples accept text plain x event level level x event timestamp timestamp x my custom header a value request rate_limit_duration_secs optional uint the time window used for the rate_limit_num option default 1 seconds request rate_limit_num optional uint the maximum number of requests allowed within the rate_limit_duration_secs time window default 9 223372036854776e 18 requests request retry_attempts optional uint the maximum number of retries to make for failed requests default 9 223372036854776e 18 retries request retry_initial_backoff_secs optional uint the amount of time to wait before attempting the first retry for a failed request after the first retry has failed the fibonacci sequence is used to select future backoffs default 1 seconds request retry_jitter_mode optional string literal enum the jitter mode to use for retry backoff behavior enum options option description full full jitter the random delay is anywhere from 0 up to the maximum current delay calculated by the backoff strategy incorporating full jitter into your backoff strategy can greatly reduce the likelihood of creating accidental denial of service dos conditions against your own systems when many clients are recovering from a failure state none no jitter default full request retry_max_duration_secs optional uint the maximum amount of time to wait between retries default 30 seconds request timeout_secs optional uint the time a request can take before being aborted datadog highly recommends that you do not lower this value below the service s internal timeout as this could create orphaned requests pile on retries and result in duplicate data downstream default 60 seconds retry_strategy optional object configurable retry strategy for http based sinks for more information about error responses see client error responses retry_strategy status_codes required uint retry on these specific http status codes relevant when type custom retry_strategy type optional string literal enum the retry strategy enum enum options option description all retry on all http status codes except for success codes 2xx custom custom retry strategy default default strategy see retrystrategy retry_action for more details none don t retry any errors including request timeouts default default tls optional object tls configuration tls alpn_protocols optional string sets the list of supported alpn protocols declare the supported alpn protocols which are used during negotiation with a peer they are prioritized in the order that they are defined tls ca_file optional string literal absolute path to an additional ca certificate file the certificate must be in the der or pem x 509 format additionally the certificate can be provided as an inline string in pem format examples path to certificate_authority crt tls crt_file optional string literal absolute path to a certificate file used to identify this server the certificate must be in der pem x 509 or pkcs 12 format additionally the certificate can be provided as an inline string in pem format if this is set and is not a pkcs 12 archive key_file must also be set examples path to host_certificate crt tls key_file optional string literal absolute path to a private key file used to identify this server the key must be in der or pem pkcs 8 format additionally the key can be provided as an inline string in pem format examples path to host_certificate key tls key_pass optional string literal passphrase used to unlock the encrypted key file this has no effect unless key_file is set examples key_pass_env_var password1 tls server_name optional string literal server name to use when using server name indication sni only relevant for outgoing connections examples www example com tls verify_certificate optional bool enables certificate verification for components that create a server this requires that the client connections have a valid client certificate for components that initiate requests this validates that the upstream has a valid certificate if enabled certificates must not be expired and must be issued by a trusted issuer this verification operates in a hierarchical manner checking that the leaf certificate the certificate presented by the client server is not only valid but that the issuer of that certificate is also valid and so on until the verification process reaches a root certificate do not set this to false unless you understand the risks of not verifying the validity of certificates tls verify_hostname optional bool enables hostname verification if enabled the hostname used to connect to the remote host must be present in the tls certificate presented by the remote host either as the common name or as an entry in the subject alternative name extension only relevant for outgoing connections do not set this to false unless you understand the risks of not verifying the remote hostname uri required string template the full uri to make http requests to this should include the protocol and host but can also include the port path and any other valid part of a uri note this parameter supports vector s template syntax which enables you to use dynamic per event values examples https 10 22 212 22 9000 endpoint input types the following table lists all

would indicate a completely idle component that is simply waiting for input a value of 1 would indicate a that is never idle this value is updated every 5 seconds component_id the vector component id

it works buffers and batches this component buffers batches data as shown in the diagram above you ll notice that vector treats these concepts differently instead of treating them as global concepts vector treats them as sink specific concepts this isolates sinks ensuring services disruptions are contained and delivery guarantees are honored batches are flushed when 1 of 2 conditions are met the batch age meets or exceeds the configured timeout_secs the batch size meets or exceeds the configured max_bytes or max_events buffers are controlled via the buffer options health checks health checks ensure that the downstream service is accessible and ready to accept data this check is performed upon sink initialization if the health c...
