Heketi plugin for Rally [benchmarking] project

What is it?

This is plugin for Rally project.

With this tool you'll be able to generate load for Heketi or CNS, using various scenarios which create, expand and delete Gluster 'file' and 'block' volumes.

How to use this plugin

Run following command once to create DB instance for Rally project:

$ tox -e heketi -- rally db create

Then, create deployment for our Heketi plugin:

$ tox -e heketi -- rally deployment create --name heketi

Now, take some sample from 'samples/' dir, update it according to your needs and run it using following command:

$ tox -e heketi -- rally task start scenario-file-name.yaml

For running OCP scenarios you need to have kube config file on runner machine and specify it in scenario context. Default path is '~/.kube/config'. Usually, such config file available on master nodes where you run 'oc' commands. Path is the same.

For more details read Rally project docs.

       -e vcenter_username='someUserName' \
       -e vcenter_password='someCoolPassword' \
       -e vcenter_vm_names="nodename1,nodename2" \
       -e vm_downtime_in_seconds=13 \
       ansible-playbooks/vmware-vms-restart.yaml

2. Restart 'glusterd' services:

   $ tox -e ansible -- ansible-playbook \
       -i "username@hostname,hostname2" \
       -e downtime_in_seconds=3 \
       ansible-playbooks/glusterd-restart.yaml 

3. Disable Heketi node:

   $ tox -e ansible -- ansible-playbook \
       -i username@hostname, \
       -e heketi_server=http://hostname:8080 \
       -e heketi_user=admin \
       -e heketi_secret=admin \
       -e heketi_node_id=FooNodeID \
       ansible-playbooks/heketi-node-disable.yaml

4. Enable Heketi node:

   $ tox -e ansible -- ansible-playbook \
       -i username@hostname, \
       -e heketi_server=http://hostname:8080 \
       -e heketi_user=admin \
       -e heketi_secret=admin \
       -e heketi_node_id=FooNodeID \
       ansible-playbooks/heketi-node-enable.yaml

5. Disable Heketi device:

   $ tox -e ansible -- ansible-playbook \
       -i "username@hostname," \
       -e heketi_server=http://hostname:8080 \
       -e heketi_user=admin \
       -e heketi_secret=admin \
       -e heketi_device_id=FooDeviceID \
       ansible-playbooks/heketi-device-disable.yaml

6. Enable Heketi device:

   $ tox -e ansible -- ansible-playbook \
       -i "username@hostname," \
       -e heketi_server=http://hostname:8080 \
       -e heketi_user=admin \
       -e heketi_secret=admin \
       -e heketi_device_id=FooDeviceID \
       ansible-playbooks/heketi-device-enable.yaml
