Here is a sample process of how to install and configure a 2DC (2 data-centers, each with 2 masters and 2 workers) and nagios for monitoring.

h2. Launch EC2 Instances

# Choose "onto-docker-X" instances (Tested with onto-docker-9).
!EC2 Management Console - Chromium_005.png|thumbnail,border=1,width=100!
# Choose the appropriate instance type (e.g. m3.medium).
!EC2 Management Console - Chromium_007.png|thumbnail,border=1,width=100!
# Open the instances for all communication.
!EC2 Management Console - Chromium_008.png|thumbnail,border=1,width=100!
# Select Number of instances: 8 in Configure Instance Details step.
!EC2 Management Console - Chromium_009.png|thumbnail,border=1,width=100!
# Launch\!

When the instances start, they pull the latest GraphDB docker image, along with LDBC 50 and start it (takes a few minutes).

h2. Configuration

Each instance can act either as a master or as a worker. For this scenario, configure them by first editing the following configuration file: [Test install of GraphDB on EC2^test.config].

Save the file either in the current folder or in the user home folder as "test.config". Just change the IP addresses for each box to one of the public IPs of the newly created instances:

# name/IP or hostname/OS user/contol JMX PORT

box1 - - 9999
box2 - - 9999
box3   - - 9999
box4 - - 9999
box5  - - 9999
box6  - - 9999
box7  - - 9999
box8  - - 9999

Be sure that the Amazon "Security groups" and instances firewalls have proper open ports.
The following assumes that you have installed (unzipped) the new-cluster-test project, provided by Ontotext as a separate ZIP file:
$ cd ~/new-cluster-test
$ ant amazon-configure
This process takes awhile, so we can now start deploying the nagios instance.

h2. Launch nagios instance

We'll need one more EC2 instance. This time choose 64-bit Amazon Linux AMI (tested again with t3.medium, though t1.micro may be enough). You'll need just SSH (22) and HTTP (80) ports open for this one.

After the instance is up, you'll need to SSH to it and run the following commands there:

$ sudo yum install docker
$ sudo service docker start
$ sudo docker login -u ontotext -p ontodocker -e
$ sudo docker pull ontotext/owlim-nagios
We're now ready to configure and run nagios. For this we need to make sure that the cluster is configured and running (that is, the previous step has finished). We'll need also one of the masters' URLs. E.g. the master in box1 above: []

$ sudo docker run -d -p 80:80 ontotext/owlim-nagios conf-and-run
{code}That's it\! The start script will read the cluster's configuration, generate one for nagios and run it. To view the results point your browser to [] or [] for graphs (you'll have to put the external IP of the nagios machine here). The credentials are nagiosadmin/nagio

h2. Run sample LDBC-based load test
This is run from the same project new-cluster-test:
- check settings in your test.config, the following parameters at the end are related to the load test
ldbc_aggregation_agents 16
ldbc_editorial_agents 2
ldbc_run_time 3600

- then start the tests
ant ldbc-run

* Note: ldbc_run_time
** LDBC benchmark required java 7
** The ldbc-run ant target depends on *Unix
