# Structured Logging
A structured logging system can be useful when your logs are destined for a
machine to parse and process. By maintaining its machine-readable characteristics,
it enables more efficient searching and aggregations when consumed by software
such as the "ELK stack".
Synapse's structured logging system is configured via the file that Synapse's
`log_config` config option points to. The file should include a formatter which
uses the `synapse.logging.TerseJsonFormatter` class included with Synapse and a
handler which uses the above formatter.
There is also a `synapse.logging.JsonFormatter` option which does not include
a timestamp in the resulting JSON. This is useful if the log ingester adds its
own timestamp.
A structured logging configuration looks similar to the following:
```yaml
version: 1
formatters:
structured:
class: synapse.logging.TerseJsonFormatter
handlers:
file:
class: logging.handlers.TimedRotatingFileHandler
formatter: structured
filename: /path/to/my/logs/homeserver.log
when: midnight
backupCount: 3 # Does not include the current log file.
encoding: utf8
loggers:
synapse:
level: INFO
handlers: [remote]
synapse.storage.SQL:
level: WARNING
```
The above logging config will set Synapse as 'INFO' logging level by default,
with the SQL layer at 'WARNING', and will log to a file, stored as JSON.
It is also possible to configure Synapse to log to a remote endpoint by using the
`synapse.logging.RemoteHandler` class included with Synapse. It takes the
following arguments:
- `host`: Hostname or IP address of the log aggregator.
- `port`: Numerical port to contact on the host.
- `maximum_buffer`: (Optional, defaults to 1000) The maximum buffer size to allow.
A remote structured logging configuration looks similar to the following:
```yaml
version: 1
formatters:
structured:
class: synapse.logging.TerseJsonFormatter
handlers:
remote:
class: synapse.logging.RemoteHandler
formatter: structured
host: 10.1.2.3
port: 9999
loggers:
synapse:
level: INFO
handlers: [remote]
synapse.storage.SQL:
level: WARNING
```
The above logging config will set Synapse as 'INFO' logging level by default,
with the SQL layer at 'WARNING', and will log JSON formatted messages to a
remote endpoint at 10.1.2.3:9999.
