Monitoring the provider side

See 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

AllocatedThreadsMax The maximum number of allocated threads GAUGE

AllocatedThreadsCurrent The current number of allocated threads GAUGE

See Creating a graph using a simple data to graph the stats of the object pool of message exchanges:
