Configure app loggers#

App loggers can be configured to define where the logs will be redirected and what is the level the logs should be displayed.

Supported redirect target:

  • STDOUT
  • FILE

Supported level:

  • FATAL
  • ERROR
  • WARN
  • INFO
  • DEBUG
  • TRACE

The following key-value pairs are the defaults:

{
    "scim_log_target": "STDOUT",
    "scim_log_level": "INFO",
    "persistence_log_target": "FILE",
    "persistence_log_level": "INFO",
    "persistence_duration_log_target": "FILE",
    "persistence_duration_log_level": "INFO",
    "script_log_target": "FILE",
    "script_log_level": "INFO"
}

To enable prefix on STDOUT logging, set the enable_stdout_log_prefix key. Example:

{"scim_log_target":"STDOUT","persistence_log_target":"STDOUT","enable_stdout_log_prefix":true}

Hybrid mapping#

As per v1.0.1, hybrid persistence supports all available persistence types. To configure hybrid persistence and its data mapping, follow steps below:

  1. Set CN_PERSISTENCE_TYPE environment variable to hybrid

  2. Set CN_HYBRID_MAPPING with the following format:

    {
    "default": "<sql>",
    "user": "<sql>",
    "site": "<sql>",
    "cache": "<sql>",
    "token": "<sql>",
    "session": "<sql>",
}

    Example:

    {
    "default": "sql",
    "user": "sql",
    "site": "sql",
    "cache": "sql",
    "token": "sql",
    "session": "sql",
}

Exposing metrics#

As per v1.0.1, certain metrics can be exposed via Prometheus JMX exporter. To expose the metrics, set the CN_PROMETHEUS_PORT environment variable, i.e. CN_PROMETHEUS_PORT=9093. Afterwards, metrics can be scraped by Prometheus or accessed manually by making request to /metrics URL, i.e. http://container:9093/metrics.

Note that Prometheus JMX exporter uses pre-defined config file (see conf/prometheus-config.yaml). To customize the config, mount custom config file to /opt/prometheus/prometheus-config.yaml inside the container.
