BSM

BSM + Centreon Integration Benefits

BSM Stream Connector sends events related data from Centreon to Micro Focus BSM (Business Service Management).

How it Works

• Every time a service or a host's state is checked, the event passes through Centreon Broker, which uses the functions defined in the Stream Connector to send state changes to BSM.

Requirements

• Integration with BSM requires the ability to access a webservice on you BSM platform. Please contact your BSM expert for this part.
• A Centreon account is required with either admin privileges or Export configuration and Broker configuration menu access in the WUI.
• A root access in command-line interface on Centreon central server is required as well.

Support

If you need help with this integration, depending on how you are using Centreon, you can:

• Commercial Edition customers: please contact the Centreon Support team.
• Open Source Edition users or Centreon IT-100 users (free versions): please visit our community platform The Watch where our users and staff will try to help you.

Integration Walkthrough

Installation

Login as root on the Centreon central server using your favorite SSH client.

In case your Centreon central server must use a proxy server to reach the Internet, you will have to export the https_proxy environment variable and configure yum to be able to install everything.

export https_proxy=http://my.proxy.server:3128
echo "proxy=http://my.proxy.server:3128" >> /etc/yum.conf

Now that your Centreon central server is able to reach the Internet, you can run:

yum install -y lua-curl epel-release
yum install -y luarocks
luarocks install luaxml

This package is necessary for the script to run. Now let's download the script:

wget -O /usr/share/centreon-broker/lua/bsm_connector.lua https://raw.githubusercontent.com/centreon/centreon-stream-connector-scripts/master/centreon-certified/bsm/bsm_connector-apiv1.lua
chmod 644 /usr/share/centreon-broker/lua/bsm_connector.lua

The BSM StreamConnnector is now installed on your Centreon central server!

Broker configuration

1. Login to the Centreon WUI using an administrator account.
2. Navigate to the Configuration > Pollers menu and select Broker configuration.
3. Click on the central-broker-master broker configuration object and navigate to the Output tab.
4. Add a new Generic - Stream connector output.
5. Name it as you want (eg. BSM) and set the right path for the LUA script: /usr/share/centreon-broker/lua/bsm_connector.lua.
6. The parameter http_server_url has to be set according to your BSM platforms characteristics:

Name	Type	Value
http_server_url	String	https://<my.bsm.server>:30005/bsmc/rest/events/<my-webservice>/

7. Save your configuration, then navigate to the Configuration > Pollers menu and select Pollers.
8. Select the Central poller and click on Export configuration.
9. Keep Generate Configuration Files and Run monitoring engine debug (-v) checked and select Move Export Files and then click on the Export button.
10. Restart the cbd service:

systemctl restart cbd

Now your central server has loaded the BSM Stream Connector and has started to send data!

To make sure that everything goes fine, you should have a look at central-broker-master.log and stream-connector-bsm.log, both located in /var/log/centreon-broker.

Advanced configuration

Parameters table

Name	Type	Value example	Explanation
http_server_url	String	https://<my.bsm.server>:30005/bsmc/rest/events/<my-webservice>/	URL of your BSM platform
http_proxy_string	String	http://your.proxy.server:3128	Proxy string needed to reach the Internet in HTTP/HTTPS
source_ci	String	Centreon (default value)	Name used to identify the transmitter
log_level	Number	2 (default value)	Verbosity level for logs 0: errors only 1: +warnings, 2: +verbose, 3: +debug
log_path	String	/var/log/centreon-broker/my-custom-logfile.log	Log file full path and name
max_buffer_size	Number	1 (default value)	Number of events to enqueue in buffer before sending
max_buffer_age	Number	5 (default value)	Maximum number of seconds before sending an event when max_buffer_size hasn't been reached

Remarks

• The default value of 2 for log_level is fine for initial troubleshooting, but can generate a huge amount of logs if you monitor a lot of hosts. In order to get less log messages, you should tune this parameter.
• The default value of 1 for max_buffer_size works fine and ensures the best response times. You might want to tune it (ie. increase it) if you have an important amount of data to send to BSM.
