*** Keywords ***

Get Logging Entry List
    [Documentation]  Get logging entry and return the object list.

    ${entry_list}=  Create List
    ${resp}=  OpenBMC Get Request  ${BMC_LOGGING_ENTRY}list  quiet=${1}
    Return From Keyword If  ${resp.status_code} == ${HTTP_NOT_FOUND}
    ${jsondata}=  To JSON  ${resp.content}

    FOR  ${entry}  IN  @{jsondata["data"]}
        Continue For Loop If  '${entry.rsplit('/', 1)[1]}' == 'callout'
        Append To List  ${entry_list}  ${entry}
    END

    # Logging entries list.
    # ['/xyz/openbmc_project/logging/entry/14',
    #  '/xyz/openbmc_project/logging/entry/15']
    [Return]  ${entry_list}

    # In this example, all error logs with "Severity" fields that are neither Informational, Debug nor
    # Notice will be returned.

    # Description of argument(s):
    # quiet                         Indicates whether this keyword should run without any output to the
    #                               console, 0 = verbose, 1 = quiet.
    # filter_struct_args            filter_struct args (e.g. filter_dict, regex, etc.) to be passed directly
    #                               to the Filter Struct keyword.  See its prolog for details.

    #  The length of the returned dictionary indicates how many logs there are.

    # Use 'Print Error Logs' to print.  Example:

    # Print Error Logs  ${error_logs}  Message.
