Session Objective Understand What is Useful To Us Let’s Go Beyond Conventional Tools

Answer the following questions: Which CPU resources are causing performance issues? How much are we wasting on storage? Can we identify memory issues before it escalates? Is disk throughput problems creating VM problems?

What do we monitor? Availability Configuration Performance Capacity

Availability Monitoring Status Monitor Cluster Status Migration issues Connectivity Hardware issues (Power supply, temperature, fan, RAID)

Monitoring Configuration Best Practice Analyzers System Center Advisor Central Monitoring via SCVMM

Key concepts for monitoring virtualization You need a map Track relationships & dependencies Visualize as you virtualize Dashboards & Reports. Context is key Everybody has to share Understand resource sharing and over-commitment Look to the future Use forecasting, trending, modelling Knowledge is power KB guidance is essential for lower time-to-resolution

1. Map - Storage topology view Map VMs and Apps to the storage they depend on

2. Visualize - Storage heatmaps Graphical views of Datastore usage and performance Click and drill-down into the ‘hot spots’

3. Sharing – Memory Pressure Dash Relate Host memory pressure to VM memory consumption, and view in-context alerts

4. Futures - Capacity Planning Reports For Clusters and Storage Forecast resource limits Predict capacity and plan for growth

5. Knowledge base

Key metrics : Over-commitment CPU Pressure # of running VM vCPU per Host Core High ratio can impact vSphere CPU Scheduler Absolute maximum = 25 Best practice 4 - 8

Key metrics : Over-commitment CPU Pressure Memory Pressure Memory allocated versus physical RAM available vSphere shares very efficiently (TPS) – but: High values can cause ballooning, or even swapping

Key metrics : Over-commitment CPU Pressure Memory Pressure Memory allocated versus physical RAM available vSphere shares very efficiently (TPS) – but: High values can cause ballooning, or even swapping

Key metrics : Over-commitment CPU Pressure Memory Pressure Disk Pressure Disk space allocated versus capacity No real performance impact – but: If VMs start to use their allocation – physical capacity can fill quickly

Key metrics : Compute CPU CPU Usage CPU Used, <90% CPU Ready, <15% CPU Co-Stop, <15 % Relate Host usage to VMs usage

Key metrics : Compute Memory Memory Usage Memory Used, <90% Memory Balloon, <50% Can cause high disk I/O in-VM due to paging Memory Swapping, = 0! Swapfile use is last resort for the Host Relate Host usage to VMs usage

Key metrics : Storage Storage space Disk Pressure is a factor! Minimum free space >100 MB At this point VM corruption will occur Also track ‘garbage/unknown’ files Also track Snapshots Relate VMs to Datastores

Key metrics : Storage Storage space Storage Latency Kernel Latency within Host ~0ms Device Latency on backend <20ms Find the hotspots of high I/O Relate VMs to Datastores

Key events: Availability and configuration Availability and Status VMs Hosts Storage Network Hardware
