RocketMQ Logger Configuration
Configuration reference for the RocketMQ Logger plugin (`rocketmq-logger`): the parameters and plugin metadata, each attribute with its type, whether it is required, its default and its accepted values.
Parameters
See plugin common configurations (opens in Apache APISIX docs) for configuration options available to all plugins.
nameserver_list — array[string] · required · since APISIX 2.12.0
List of RocketMQ nameservers.
topic — string · required · since APISIX 2.12.0
Target topic to push the data to.
key — string · optional · since APISIX 2.12.0
Key of the message.
tag — string · optional · since APISIX 2.12.0
Tag of the message.
log_format — object · optional · since APISIX 3.2.0
Custom log format using key-value pairs in JSON format. Values can reference built-in variables (opens in Apache APISIX docs).
In APISIX from 3.15.0, log format nested structures are supported up to five levels deep. In API7 Enterprise, only flat key-value structures are supported; nested structures are not yet supported.
You can also configure log format on a global scale using the plugin metadata (opens in Apache APISIX docs), which configures the log format for all rocketmq-logger plugin instances. If the log format configured on the individual plugin instance differs from the log format configured on plugin metadata, the log format configured on the individual plugin instance takes precedence. See the example for more details.
log_format_extra — object · optional · since APISIX 3.18.0 · API7 Gateway 3.9.15
Additional fields to add to the default log entry, using key-value pairs in JSON format. Values can reference built-in variables (opens in Apache APISIX docs). A configured field does not overwrite an existing default field. A plugin instance takes precedence over plugin metadata; setting an empty object on the instance disables the metadata value. When log_format is configured, log_format_extra is ignored. Introduced in API7 Enterprise 3.9.15 and 3.10.2, and APISIX 3.18.0.
timeout — integer · optional · default: 3 · since APISIX 2.12.0
Timeout for the upstream to send data.
use_tls — boolean · optional · default: false · since APISIX 2.12.0
If true, verify SSL.
access_key — string · optional · since APISIX 2.12.0
Access key for ACL. Setting to an empty string will disable the ACL.
secret_key — string · optional · since APISIX 2.12.0
Secret key for ACL. The value is encrypted with AES before being stored in etcd.
name — string · optional · default: rocketmq logger · since APISIX 2.12.0 · API7 Gateway 3.8.6
Unique identifier of the plugin for the batch processor. If you use Prometheus to monitor APISIX metrics, the name is exported in apisix_batch_process_entries.
meta_format — string · optional · default: default · since APISIX 2.12.0
Valid values: default or origin
Format to collect the request information. Setting to default collects the information in JSON format and origin collects the information with the original HTTP request. See the example for more details.
include_req_body — boolean · optional · default: false · since APISIX 2.12.0
If true, include the request body in the log. Note that if the request body is too big to be kept in the memory, it can not be logged due to NGINX's limitations.
include_req_body_expr — array[array] · optional · since APISIX 2.12.0
An array of one or more conditions in the form of APISIX expressions (opens in Apache APISIX docs). Used when the include_req_body is true. Request body would only be logged when the expressions configured here evaluate to true.
include_resp_body — boolean · optional · default: false · since APISIX 2.12.0
If true, include the response body in the log.
include_resp_body_expr — array[array] · optional · since APISIX 2.12.0
An array of one or more conditions in the form of APISIX expressions (opens in Apache APISIX docs). Used when the include_resp_body is true. Response body would only be logged when the expressions configured here evaluate to true.
max_req_body_bytes — integer · optional · default: 524288 · since APISIX 3.16.0 · API7 Gateway 3.10.3
Valid values: greater than or equal to 1
Maximum request body size in bytes to include in the log. If the request body exceeds this value, it will be truncated. Available in APISIX from 3.16.0.
max_resp_body_bytes — integer · optional · default: 524288 · since APISIX 3.16.0 · API7 Gateway 3.10.3
Valid values: greater than or equal to 1
Maximum response body size in bytes to include in the log. If the response body exceeds this value, it will be truncated. Available in APISIX from 3.16.0.
batch_max_size — integer · optional · default: 1000 · since APISIX 2.12.0 · API7 Gateway 3.8.6
Valid values: greater than 0
The number of log entries allowed in one batch. Once reached, the batch will be sent to the logging service. Setting this parameter to 1 means immediate processing.
inactive_timeout — integer · optional · default: 5 · since APISIX 2.12.0 · API7 Gateway 3.8.6
Valid values: greater than 0
The maximum time in seconds to wait for new logs before sending the batch to the logging service. The value should be smaller than buffer_duration.
buffer_duration — integer · optional · default: 60 · since APISIX 2.12.0 · API7 Gateway 3.8.6
Valid values: greater than 0
The maximum time in seconds from the earliest entry allowed before sending the batch to the logging service.
retry_delay — integer · optional · default: 1 · since APISIX 2.12.0 · API7 Gateway 3.8.6
Valid values: greater than or equal to 0
The time interval in seconds to retry sending the batch to the logging service if the batch was not successfully sent.
max_retry_count — integer · optional · default: 0 · since APISIX 2.12.0 · API7 Gateway 3.8.6
Valid values: greater than or equal to 0
The maximum number of unsuccessful retries allowed before dropping the log entries.
Plugin Metadata
log_format — object · optional · since APISIX 2.12.0
Custom log format using key-value pairs in JSON format. Values can reference built-in variables (opens in Apache APISIX docs).
In APISIX from 3.15.0, log format nested structures are supported up to five levels deep. In API7 Enterprise, only flat key-value structures are supported; nested structures are not yet supported.

A configured field does not overwrite an existing default field. A plugin instance takes precedence over plugin metadata; setting an empty object on the instance disables the metadata value. When log_format is configured, log_format_extra is ignored. Introduced in API7 Enterprise 3.9.15 and 3.10.2, and APISIX 3.18.0.
max_pending_entries — integer · optional · default: 8192 in APISIX 3.18.0 and in API7 Enterprise 3.9.19 and 3.10.6; none in API7 Enterprise 3.9.18 and 3.10.5 · since APISIX 3.15.0 · API7 Gateway 3.8.17
Valid values: greater than or equal to 1
Maximum number of entries waiting in the batch processor. New entries are discarded when the backlog reaches the limit.
Introduced in API7 Enterprise 3.8.17 and APISIX 3.15.0.
The default changed to 8192 in APISIX 3.18.0 and in API7 Enterprise 3.9.19 on the 3.9 line and 3.10.6 on the 3.10 line. In API7 Enterprise 3.9.18 and 3.10.5, and in earlier APISIX versions, omitting the parameter leaves the backlog unlimited.
