Coommunity - Allan McAleavy- Hunting noisy neighbours using VROPS & Grafana.
When hunting for noisy neighbour workloads from a high level storage viewpoint we can only drill down as far as an ESX Host or VMFS Volume. This initially led to the development of dashboards within VROPS to allow top-down (ESX Host to VM) and bottom-up (VMFS to VM) analysis to identify these workloads. This approach worked well however teams had to use different tools & different dashboards to correlate the data. In this talk I will show how we use the VROPS python API to gather I/O data and correlate this with array data using Grafana to hunt down noisy workloads from an ESX node and VMFS view. I will also show how we can use this methodology to Identify high CPU workloads and also help us look at overall ESX and VM performance using this data.
