h1. Introduction

All components based on the Petals Component Development Kit provide following metrics:

** service provider invocation response times per operation and execution status,
* consumer side:
** no metric.

h1. Monitoring the provider side

h2. Monitoring the message exchange acceptor thread 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 thread 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-thread-pool \-- \-n <component-id>}}
* Output fields of the script/command:
|| Name || Description || Type ||
| {{ActiveThreadsMax}} | The maximum number of active threads | GAUGE |
