# Akamas logs Akamas allows dumping log entries from a specific service, workspace, workflow, study, trial, and experiment, for a specific timeframe and at different log levels. ## Akamas CLI for logs Akamas logs can be dumped via the following CLI command: ```bash akamas log ``` This command provides many filters which can be retrieved with the following command: ```bash akamas log --help ``` which should return ``` Usage: akamas log [OPTIONS] [MESSAGE] Show Akamas logs Options: -d, --debug Show extended error messages if present. --page-size INTEGER Number of log lines to be retrieved NOTE: This argument is mutually exclusive with arguments: [dump, no_pagination]. --no-pagination Disable pagination and print all logs NOTE: This argument is mutually exclusive with arguments: [dump, page_size]. --dump Print the logs without pagination and formatting NOTE: This argument is mutually exclusive with arguments: [page_size, no_pagination]. -f, --from [%Y-%m-%d|%Y-%m-%dT%H:%M:%S|%Y-%m-%d %H:%M:%S|%Y-%m-%dT%H:%M:%S.%f|%Y-%m-%d %H:%M:%S.%f|[-]nw|[-]nd|[-]nh|[-]nm|[-]ns] The start timestamp of the logs -t, --to [%Y-%m-%d|%Y-%m-%dT%H:%M:%S|%Y-%m-%d %H:%M:%S|%Y-%m-%dT%H:%M:%S.%f|%Y-%m-%d %H:%M:%S.%f|[-]nw|[-]nd|[-]nh|[-]nm|[-]ns] The end timestamp of the logs -s, --study TEXT UUID or name of the Study -e, --exp INTEGER Number of the experiment --trial INTEGER Number of the trial -y, --system TEXT UUID or name of the System -W, --workflow TEXT UUID or name of the Workflow -l, --log-level TEXT Log level -S, --service TEXT Akamas service --without-metadata Hide metadata --sorting [ASC|DESC] Sorting order of the timestamps -ws, --workspace TEXT UUID or name of the Workspace to visualize. When empty, system logs will be returned instead --help Show this message and exit. ``` For example, to get the list of the most recent Akamas errors: ```bash akamas log -l ERROR ``` which should return something similar to: ``` timestamp system provider service message ============================================================================================================================================================================================================================================================== 2022-05-02T15:51:26.88 - - airflow Task failed with exception 2022-05-02T15:51:26.899 - - airflow Failed to execute job 2 for task Akamas_LogCurator_Task 2022-05-02T15:56:29.195 - - airflow Task failed with exception 2022-05-02T15:56:29.215 - - airflow Failed to execute job 3 for task Akamas_LogCurator_Task 2022-05-02T16:01:55.587 - - license 2022-05-02 16:01:47.426 ERROR 1 --- [ main] c.a.m.utils.rest.RestHandlers : has failed with returning a response: {"httpStatus":400,"timestamp":"2022-05-02T16:01:47.413638","error":"Bad Request","message":"The following metrics: 'spark.spark_application_duration' were not found in any of the components of the system 'analytics_cluster'","path":null} 2022-05-02T16:01:55.587 - - license 2022-05-02 16:01:47.434 ERROR 1 --- [ main] c.a.m.MigrationApplication : Unable to complete operation.
