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

h1. Monitoring the transporters

h2. Monitoring the local transporter

{anchor:localTransporter_DeliveredMsg}
h3. Delivered messages

!petals-local-transporter-delivered-messages.png|align=center!

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.sh \-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|How to create a graph with Cacti#Creating a graph using a data query]:
** the data query definition to put in a file:

h2. Monitoring the remote transporter

h3. Delivered messages (incoming or outgoing messages)
