Configurationedit

While initializing the agent you can provide the following configuration options:

serviceNameedit

Your Elastic APM service name.

serverUrledit

The URL used to make requests to the APM Server.

serviceVersionedit

The version of the app. This could be the version from your package.json file, a git commit reference, or any other string that might help you pinpoint a specific version. Furthermore this option is used on the APM Server to find the right sourcemap file to apply to the stack trace.

activeedit

A boolean specifying if the agent should be active or not. If active, the agent will send APM transactions and track errors. This option can be used to deactivate the agent in your staging environment. It can also be used to sample a number of clients, here is an example to sample 10% of the page loads:

var options = {
  active: Math.random() < 0.1
}

logLeveledit

Set the verbosity level for the agent. Note that this does not have any influence on the types of errors that are sent to the APM Server. This option is useful when you want to report an issue with the agent to us.

Possible levels are: trace, debug, info, warn, error.

flushIntervaledit

The agent maintains two in-memory queues to record transactions and errors when they are added. This option sets the flush interval in milliseconds for these queues.

Error throttlingedit

To throttle the number of errors send to the APM Server, you can use the following options:

errorThrottleLimitedit

errorThrottleIntervaledit

By default the agent can only send (up to) 20 errors every 30000 milliseconds.

Transaction throttlingedit

transactionThrottleLimitedit

transactionThrottleIntervaledit

By default the agent can only send (up to) 20 transactions every 30000 milliseconds.
