A Petals ESB container is composed of several internal components. Each one can be monitored and provides several metrics:

• the transporters:
  • the local transporter:
    • delivered messages

Monitoring the transporters

Monitoring the local transporter

Delivered messages

The number of messages delivered by the local transporter can be graphed:

• by message exchange status, see Creating a graph using a simple data:
  • Script/Command of the data input method: petals_cli -h <petals_host> -n <petals_jmx_port> -u <petals_jmx_user> -p <petals_jmx_password> -c – monitoring -o local-transporter -f delivered-messages – -m
  • Output fields of the script/command:

    Name	Description	Type
    Active	Number of delivered message with status 'Active'	COUNTER
    Done	Number of delivered message with status 'Done'	COUNTER
    Error	Number of delivered message with status 'Error'	COUNTER

• by message exchange status and filtered for a dedicated endpoint, or a service, or an interface, see Creating a graph using a data query:
  • the query to put in a file:

    To filter by service, replace <arg_index>, <arg_query> and <arg_get> by:

            <arg_index>-- --list-services</arg_index>
            <arg_query>-- --query-services</arg_query>
            <arg_get>-- --query-services</arg_get>
    

    To filter by interface, replace <arg_index>, <arg_query> and <arg_get> by:

            <arg_index>-- --list-interfaces</arg_index>
            <arg_query>-- --query-interfaces</arg_query>
            <arg_get>-- --query-interfaces</arg_get>
