2.6. Debugging and Logging¶
You can set PI_LOGLEVEL
to a value 10 (Debug), 20 (Info), 30 (Warning),
40 (Error) or 50 (Critical).
If you experience problems, set PI_LOGLEVEL = 10
restart the web service
and resume the operation. The log file privacyidea.log
should contain
some clues.
You can define the location of the logfile using the key PI_LOGFILE
.
Usually it is set to:
PI_LOGFILE = "/var/log/privacyidea/privacyidea.log"
2.6.1. Advanced Logging¶
In the advanced logging you can use the Python logging configuration to define in a fine graded way which information should be logged where. For more details see python logging config.
You can also define a more detailed logging by specifying a
log configuration file. By default the file is /etc/privacyidea/logging.cfg
.
You can change the location of the logging configuration file in The Config File like this:
PI_LOGCONFIG = "/path/to/logging.yml"
Since Version 3.3 the logging configuration can be written in YAML 1. Such a YAML based configuration could look like this:
version: 1
formatters:
detail:
class: privacyidea.lib.log.SecureFormatter
format: '[%(asctime)s][%(process)d][%(thread)d][%(levelname)s][%(name)s:%(lineno)d] %(message)s'
handlers:
mail:
class: logging.handlers.SMTPHandler
mailhost: mail.example.com
fromaddr: privacyidea@example.com
toaddrs:
- admin1@example.com
- admin2@example.com
subject: PI Error
formatter: detail
level: ERROR
file:
# Rollover the logfile at midnight
class: logging.handlers.RotatingFileHandler
backupCount: 5
maxBytes: 1000000
formatter: detail
level: INFO
filename: /var/log/privacyidea/privacyidea.log
syslog:
class: logging.handlers.SysLogHandler
address: ('192.168.1.110', 514)
formatter: detail
level: INFO
loggers:
# The logger name is the qualname
privacyidea:
handlers:
- file
- mail
level: INFO
root:
handlers:
- syslog
level: WARNING
Different handlers can be used to send log messages to log-aggregators like splunk 2 or logstash 3.
The old python logging config file format is also still supported:
[formatters]
keys=detail
[handlers]
keys=file,mail
[formatter_detail]
class=privacyidea.lib.log.SecureFormatter
format=[%(asctime)s][%(process)d][%(thread)d][%(levelname)s][%(name)s:%(lineno)d] %(message)s
[handler_mail]
class=logging.handlers.SMTPHandler
level=ERROR
formatter=detail
args=('mail.example.com', 'privacyidea@example.com', ['admin1@example.com',\
'admin2@example.com'], 'PI Error')
[handler_file]
# Rollover the logfile at midnight
class=logging.handlers.RotatingFileHandler
backupCount=14
maxBytes=10000000
formatter=detail
level=DEBUG
args=('/var/log/privacyidea/privacyidea.log',)
[loggers]
keys=root,privacyidea
[logger_privacyidea]
handlers=file,mail
qualname=privacyidea
level=DEBUG
[logger_root]
level=ERROR
handlers=file
Note
These examples define a mail handler, that will send emails to certain email addresses, if an ERROR occurs. All other DEBUG messages will be logged to a file.
Note
The filename extension is irrelevant in this case
