relasticapm extracts sampled transaction documents from Elasticsearch, and reconstitutes
them into their original Elastic APM ND-JSON event format suitable for sending to Elastic APM
Server.
For each transaction event a configurable command is executed. The command's stdin will be fed
with an ND-JSON event stream containing the agent metadata and the single event. The default
command executed is a curl command to send the transaction events to a local APM Server. The
server URL can be configured with $ELASTIC_APM_SERVER_URL. The command can be overridden
using the -exec flag, for example -exec "jq .".
By default, events will be returned for the past hour. It is possible to specify an alternative
start time by passing -since with either a timestamp or Elasticsearch date math. Note that
relasticapm estimates the original sample rate by calculating the sampled-to-total transaction
ratio, so a short duration may lead to greater inaccuracy.
