# Telemetry

|
The Consul agent collects various metrics data at runtime about the performance
|
2014-02-08 00:41:03 +00:00
|
|
|
of different libraries and sub-systems. These metrics are aggregated on a ten second
|
|
|
|
|
interval and are retained for one minute.
|
|
|
|
|
|
2014-02-18 23:30:07 +00:00
|
|
|
To view the telemetry information, you must send a `USR1` signal to the Consul
|
2014-02-08 00:41:03 +00:00
|
|
|
process. Windows users must use the `BREAK` signal instead.
|
2014-02-18 23:30:07 +00:00
|
|
|
Once Consul receives the signal, it will dump the current telemetry
|
2014-02-08 00:41:03 +00:00
|
|
|
information to the stderr of the agent.
|
|
|
|
|
|
|
|
|
|
In general, the telemetry information is used for debugging or otherwise
|
2014-02-18 23:30:07 +00:00
|
|
|
getting a better view into what Consul is doing.
