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

h1. Monitoring the transporters

h2. Monitoring the local transporter

h3. 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|How to create a graph with Cacti#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 |
