CloudStack Tuning

Sign up or log in to save this to your schedule and see who's attending!

CloudStack performs well with default configuration for most of the deployment. But every system has a limit, beyond which the performance degrades. To get rid of these performance issues we have to tune the management server by tweaking some configurations. In this presentation, Sudhansu will discuss various cloudstack configurations and the load that will make management server exhausted. We will also discuss common issues and solutions.
Ex: A cloudstack Simulator based environment with 4K hosts, 4K accounts, 12K Vms, 8K router Vms, 2 management server nodes, 8G heap size started showing hosts in alert and disconnected state after 20 minutes of operation. The root cause was found to be less number of database connections.The configuration that determines the maximum active connection is 'db.cloud.maxActive'. To address this issue the we configured this to 1000 (default 250).
