Example config file:
apm-server: hosts: ["localhost:8200"] rum: enabled: true output: elasticsearch: hosts: ElasticsearchAddress:9200 queue.mem.events: 4096 max_procs: 4
If you are using an X-Pack secured version of Elastic Stack, you need to specify credentials in the config file before you run the commands that set up and start APM Server. For example:
output.elasticsearch: hosts: ["ElasticsearchAddress:9200"] username: "elastic" password: "elastic"
Defines the host and port the server is listening on. Use "unix:/path/to.sock" to listen on a unix domain socket. Defaults to localhost:8200.
Maximum permitted size of a request’s header accepted by the server to be processed (in Bytes). Defaults to 1048576 Bytes (1 MB).
Maximum permitted duration for reading an entire request. Defaults to 30 seconds.
Maximum permitted duration for writing a response. Defaults to 30 seconds.
Maximum duration in seconds before releasing resources when shutting down the server. Defaults to 5 seconds.
Maximum permitted size of an event accepted by the server to be processed (in Bytes). Defaults to 307200 Bytes.
Configuration options: generaledit
Maximum number of TCP connections to accept simultaneously. Default value is 0, which means unlimited.
Authorization token for sending data to the APM server. If a token is set, the agents must send it in the following format: Authorization: Bearer <secret-token>. The token is not used for RUM endpoints. By default, no authorization token is set.
If true, APM Server captures the IP of the instrumented service and its User Agent if any. Enabled by default.
When set to true APM Server exposes golang expvar. Disabled by default.
Configure the url to expose expvar.
Enables self instrumentation of the APM Server itself. Disabled by default.
Loads pipeline definitions to Elasticsearch on APM Server startup. Defaults to false.
Overwrites existing pipeline definitions in Elasticsearch. Defaults to true.
Data is buffered in a memory queue before it is published to the configured output.
queue.mem.* settings modify the queue behavior.
Maximum number of events the memory queue can buffer. Read more about how this setting can be used for tuning data ingestion. Default value is 4096.
Hints the minimum number of events stored in the queue, before providing a batch of events to the outputs. A value of 0 (the default) ensures events are immediately available to be sent to the outputs.
Maximum duration after which events are available to the outputs, if the number of events stored in the queue is < min_flush_events. Default value is 1 second.
Sets the maximum number of CPUs that can be executing simultaneously. The default is the number of logical CPUs available in the system.
