h1. Introduction
The probes available in the Petals internals and components are able to send JMX notifications when they detect a defect. These notifications can be sent to Nagios with a dedicated monitoring command of Petals CLI that receive JMX notifications and write them in the channel of Nagios passive checks.
{gliffy:name=Nagios passive checks|size=L|align=center|version=2}
The daemon *{{petals-cli-nagios}}* listen JMX notifications coming from Petals ESB nodes using a dedicated Petals CLI command. When it receives a JMX notification, it formats and prints an external command for Nagios. The host and service emitting the JMX notification are transformed into Nagios host and Nagios service through a mapping file.

h1. Installation
These integration of Petals ESB, Petals CLI and Nagios is available on Debian-based system and is packaged as a Debian package: {{petals-cli-cmd-monitoring-so-nagios}}.
{tip}To run on other operating system, we need your contribution to port the daemon script wrapping Petals CLI on this operating system.{tip}
See [Installing Petals CLI using the Debian packages] to get more information on this Debian package.
h1. Configuration
Once your Nagios installation is configured to accept external commands, you must verify in {{/etc/petals-cli/petals-cli-nagios}} that the expected Nagios pipe file is set according to your Nagios installation. The default value is the one associated to the Debian package of Nagios.
To add a new defect subscription to sent to Nagios:
# create a new file in the directory {{/etc/petals-cli/nagios-subscriptions-available}} from the template {{/etc/petals-cli/nagios-subscriptions-available/nagios-subscription-template}}:
{code}
# JMX connection information to the Petals ESB container
#
host=localhost
port=7700
username=petals
password=petals
# The subscription object and its arguments
#
subscription-object=petals-bc-soap
extra-args=-n petals-bc-soap -t file:///etc/petals-cli/nagios-mapping-rules.properties
{code}
where the first part is the required JMX connection information to establish a communication with a Petals ESB container, and the second part is dedicated to the wanted defect.
# configure the file {{/etc/petals-cli/nagios-mapping-rules.properties}} to map the hosts and services declared into Nagios with your Petals ESB installation,
# you can test your defect subscription using the script {{/usr/bin/petals-cli-nagios}}:
{code}
> sudo /usr/bin/petals-cli-nagios <your-defect-subscription-file>
{code}
# once your defect subscription is working, just create a link into the directory {{/etc/petals-cli/nagios-subscriptions-enable}}, and restart the service {{petals-cli-nagios}}.

h3. Petals BC SOAP
The defects of the BC SOAP are supported by the subscription object 'petals-bc-soap'.
The defect emitter identifier is based on the template: {{<component-id>@<hostname>}}, where <component-id> is the JBI identifier of the BC SOAP sending the defect from the Petals ESB container running on <hostname>.
The following defects can be notified:
|| Defect || Identifier ||
| HTTP thread pool exhausted | {{org.ow2.petals.bc.soap.httpserver.threadpool.exhausted}} |
| Web-service client pool exhausted | {{org.ow2.petals.bc.soap.serviceclientspool.exhausted}} |
