Logging properties#
Примечание
Ниже приведена оригинальная документация Trino. Скоро мы ее переведем на русский язык и дополним полезными примерами.
log.annotation-file
#
Type: string
An optional properties file that contains annotations to be included with each log message. This can be used to include machine-specific or environment-specific information into logs which are centrally aggregated. The annotation values can contain references to environment variables.
environment=production
host=${ENV:HOSTNAME}
log.format
#
Type: string
Default value:
TEXT
The file format for log records. Can be set to either TEXT
or JSON
. When
set to JSON
, the log record is formatted as a JSON object, one record per
line. Any newlines in the field values, such as exception stack traces, are
escaped as normal in the JSON object. This allows for capturing and indexing
exceptions as singular fields in a logging search system.
log.path
#
Type: string
The path to the log file used by Trino. The path is relative to the data
directory, configured to var/log/server.log
by the launcher script as
detailed in Running Trino. Alternatively, you can write logs to separate
the process (typically running next to Trino as a sidecar process) via the TCP
protocol by using a log path of the format tcp://host:port
.
log.max-size
#
Type: data size
Default value:
100MB
The maximum file size for the general application log file.
log.max-total-size
#
Type: data size
Default value:
1GB
The maximum file size for all general application log files combined.
log.compression
#
Type: string
Default value:
GZIP
The compression format for rotated log files. Can be set to either GZIP
or NONE
. When
set to NONE
, compression is disabled.
http-server.log.enabled
#
Type: boolean
Default value:
true
Flag to enable or disable logging for the HTTP server.
http-server.log.compression.enabled
#
Type: boolean
Default value:
true
Flag to enable or disable compression of the log files of the HTTP server.
http-server.log.path
#
Type: string
Default value:
var/log/http-request.log
The path to the log file used by the HTTP server. The path is relative to the data directory, configured by the launcher script as detailed in Running Trino.
http-server.log.max-history
#
Type: integer
Default value:
15
The maximum number of log files for the HTTP server to use, before log rotation replaces old content.
http-server.log.max-size
#
Type: data size
Default value:
unlimited
The maximum file size for the log file of the HTTP server. Defaults to
unlimited
, setting a data size value limits the file size
to that value.
