Logging Configuration
=====================

.. note::
   Default logging level of "logging.level.org.onap.cps" is set to "INFO".

.. code-block:: bash

   logging:
    level:
        org:
            springframework: INFO
            onap:
                cps: INFO

CPS Log pattern
---------------

.. code-block:: java

   <pattern>
	   {
	     "timestamp" : "%timestamp", // 2022-01-28 18:39:17.768
	     "severity": "%level",   // DEBUG
	     "service": "${springAppName}",  // cps-application
	     "trace": "${TraceId}", // e17da1571e518c59
	     "span": "${SpanId}", // e17da1571e518c59
	     "pid": "${PID}", //11128
	     "thread": "%thread", //tp1901272535-29
	     "class": "%logger{40}", .// o.onap.cps.aop.CpsLoggingAspectService
	     "rest": "%message" // Execution time ...
	   }
   </pattern>

Change logging level
--------------------

- Curl command 1. Check current log level of "logging.level.org.onap.cps" if it is set to it's default value (INFO)

.. code-block:: java

    curl --location --request GET 'http://{cps-service-name:cps-management-port}/manage/loggers/org.onap.cps' \
    --header 'Content-Type: application/json; charset=utf-8'

    Response body : HTTP Status 200

    {
        "configuredLevel": "INFO",
        "effectiveLevel": "INFO"
    }

- Curl command 2. Change logging level of "logging.level.org.onap.cps" to "DEBUG"

.. note::
   Below-mentioned endpoint  will change the log level at runtime. After executing the curl command "effectiveLevel" will set and applied immediately without restarting CPS service.

.. code-block:: java

    curl --location --request POST 'http://{cps-service-name:cps-management-port}/manage/loggers/org.onap.cps' \
    --header 'Content-Type: application/json; charset=utf-8' \
    --data-raw '{
                    "configuredLevel": "DEBUG"
                }'

    Response body : HTTP Status 204

- Curl command 3. Verify if log level of "logging.level.org.onap.cps" is changed from 'INFO' to 'DEBUG'

.. code-block:: java

    curl --location --request GET 'http://{cps-service-name:cps-management-port}/manage/loggers/org.onap.cps' \
    --header 'Content-Type: application/json; charset=utf-8'

    Response body : HTTP Status 200

    {
    "configuredLevel": "DEBUG",
    "effectiveLevel": "DEBUG"
    }

Location of log files
---------------------
By default, Spring Boot will only log to the console and will not write log files.

Measure Execution Time of CPS Service
-------------------------------------

.. note::
   Make sure effective log level of "logging.level.org.onap.cps" is 'DEBUG'. This can be verified by executing curl command 3.

Execute CPS service that you want to calculate total elapsed time and log as shown below

Logging & Diagnostics
=====================

General Guidelines
------------------
CPS-Core logs are sent to `STDOUT` in order to leverage the Kubernetes logging architecture.

These logs are available using the following command:

.. code:: bash

    kubectl logs <cps-core-pod>

The default configuration for CPS logs is the INFO level.

This architecture also makes all logs ready to be sent to an Elastic-search Log-stash and Kibana (ELK) stack or similar.

Enabling tracing for all executed sql statements is done by changing hibernate
loggers log level

Logger configuration is provided as a chart resource :

Health
------

Cps-Core health status and state can be checked using the following endpoint.
This also includes both the liveliness state and readiness state.

.. code::

    http://<cps-component-service-name>:8081/manage/health/

Metrics
-------

Prometheus Metrics can be checked at the following endpoint
