Post-Mortem analysis

What's inside the VMs ?

Each virtual machine (VM) offer a toolbox to analyse various datas from the experimentation made with kolla-g5k. The datas themselves are also located inside the VM during the creation of the VM.

You'll find :

  • Nginx exposed on port 8000. It allows you to browse Rally reports, confs and logs.
  • Grafana exposed on port 3000. It gives access of all the metrics collected during the experimentation
  • Kibana exposed on port 5601. It let you explores the logs.

List of provided experimentation

  • idle : todo wiki url
  • load-ded : todo wiki url
  • load-default : todo wiki url
  • load-clust-rabbit
  • concurrency : todo wiki url

Accessing the results

Start a specific virtual machine :

vagrant up <experimentation>

Shutdown the virtual machine

vagrant halt <experimentation>

Creating new results

todo

Known limitation

  • The current implementation is tight to Grid'5000.
  • When creating a new set of result, indexing all the logs in elasticsearch will take some time.
  • From time to time VMs root filesystem goes read-only. Manually fsck the root partition and reboot may solve the issue fsck /dev/vg0/lv_root.
