h1. Introduction

All components based on the Petals Component Development Kit provide following metrics:
* provider side:
** message exchange acceptor pool metrics,
** message exchange processor object pool metrics,
** message exchange processor thread pool metrics,
** message exchange counter
** message exchange processing response times,
* consumer side:
** no metric.

See [Creating a graph using a simple data|How to create a graph with Cacti#Creating a graph using a simple data] to graph the stats of the pool accepting message exchanges:
* 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 generic \-f mex-acceptor-pool \-- \-n <component-id>}}
* Output fields of the script/command:
|| Name || Description || Type ||

h2. Monitoring the message exchange processor object pool

See [Creating a graph using a simple data|How to create a graph with Cacti#Creating a graph using a simple data] to graph the stats of the object pool of message exchanges:
* 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 generic \-f mex-processor-object-pool \-- \-n <component-id>}}
