3 SmartCloud Monitoring: Why is it important

4 Monitoring the VMware environment with IBM SmartCloud Monitoring - Why it is important? VCenter provides monitoring of hypervisor; static alarms & events that can be sent to an event management system. Which is fine if your infrastructure is static and you only care if performance exceeds a certain capacity or performance limit SmartCloud Monitoring provides in ONE tool: Dynamic thresholding Predictive Analytics Capacity planning Storage and Network monitoring Reporting for performance trends OS Monitoring Monitoring across servers, storage phys & virt view Integrated monitoring for Virtualization, Applications, Middleware, and more. Easy Integration into other parts of the Tivoli portfolio

5 Operational Health Dashboard

6 SmartCloud Monitoring Health Summary Dashboard: Great tool for Operations team

7 Health Dashboard Dashboards with holistic view of health of whole environment Out of the box contextual views of health (availability, performance and capacity) in the complete context of the virtual environment to include physical and virtual server, storage and network resources. Integrates across our tool set to merge physical & virtual data Storage, Network, ITM, TADDM & VMware Views with performance and capacity reports for assessment of environment and long term trend analysis.

8 Best Practices for SmartCloud Monitoring of VMware

9 Monitoring a Traditional VMware Environment ESX/ESXi servers managed by vcenter Best Practice Deployment is to deploy 1 Agent per vcenter VMotion between similar hardware IBM Tivoli Monitoring with vcenter Server: An Agent is installed on Windows or Linux The VMware VI Agent is configured to monitor remotely through vcenter Multi-Instance Agent Spare Remote TEMS Agent-less OS Monitors Windows/ Windows/ Linux Windows/ Linux Windows/ Linux Linux HUB TEMS TEPS Remote TEMS Remote TEMS OS OS OS Agents OS Agents Agents Agents VI Agent VI Agent vcenter Server vcenter Server ESX/E ESX/E ESX/E ESX/E SXiESX/E SXiESX/E SXiESX/E SXiESX/E SXiESX/E SXiESX/E SXiESX/E SXiESX/E SXiESX/E SXiESX/E SXi SXi SXi SXi

10 Deployment Scalability/Sizing Virtual Center/vCenter For Virtual Center 2.5 the maximums are 200 ESX hosts or 2000 virtual machines. For VCenter 4.1 & 5.0 the maximums are 1000 ESX hosts or 10,000 virtual machines. If vcenter has capacity, Agent can be run on vcenter Disk Space 200 Meg for Agent Short Term History Data: 85 Meg for 10 ESX servers 415 Meg for 50 ESX servers 1.6 Gig for 200 ESX servers 4 Gig for 500 ESX servers

11 Deployment Scalability/Sizing Unless vcenter environments are small, recommend 1 vcenter per Agent instance Multiple Vmware VI Agent instances may run on a server Vcenter Failover: Agent installed on VCenter- automatically will monitor the VCenter as it fails over. Agent installed on another machine - Install 2 VMWare VI Agent instances and then create situations and automation to stop the instance that is monitoring the inactive VCenter and start the other VMware VI instance.

12 Monitoring Recommendations Out-of-the-box Best Practice Situation to monitor Resource Pool CPU and Memory utilization Disk and Network I/O ESX/ESXi utilization VM utilization including CPU Ready Data Store utilization Cluster Utilization (CPU, Effective CPU, Memory, and Effective Memory) Clone the out-of-the-box Situations In addition to the out-of the box Situations, monitor: Monitor to ensure VM Tools are installed and up to date Use TCR Reports or OMNIbus to monitor high VMotion rates for specific servers and clusters Key workspaces include Top 5/Bottom 5 report shown

13 Top 5 / Bottom 5 Clusters Links provided for drilldown Top 5/Bottom 5 Cluster for CPU and Memory

14 Link from VMware Agent to OS Agent Link from VMware Agent to OS Agent

15 TCR Report: Balanced Clusters Unbalanced Can t move workload to this cluster because it s almost out of datastore space On one screen, I can check all of the key resources to see if my workload is balanced

16 Other Monitoring Considerations Other Key Attributes: Percent Ready should never be above 10%. Recommend WARNING at 5% and CRITICAL at 10% sustained utilization Hyper-threading CPUs can drive Percent Ready higher can be disabled in BIOS. Disk Latency including queue, device, and kernel latency Balloon Usage should be low. In order to use Balloon memory, you must have VMtools installed. Guest Swap Used should be zero or performance will degrade Resource Pool CPU Usage Percentage takes into account reservation Resource Pool Memory Percentage takes into account reservation Percent Effective CPU and Memory Utilization for Clusters

18 Additional Integrations

19 Additional Integrations NetApp Storage Agent: TADDM DLA discovers the vcenter environment/topology TADDM provides change data to VMware Health Dashboard ITM Agent provides integration with the Director Server Allows for Management of VMware resources Historical Collection of HW data Agent provides storage metrics in TEP Integrates into Health Dashboard Warehouse storage metrics for reporting and analysis Network Monitoring Agent Monitor switches used by Vmware Integrate Network Events into Dashboard ITM VI Agent TPC Tivoli Storage Productivity Center: TADDM DLA IBM Director Integration Provides Monitoring data in ITM Integrates into Health Dashboard TADDM Integration Health Dashboard NetApp Agent DFM IBM Storage Hitachi EMC NetApp NetApp vcenter Server Network Switches Network Switches ESX/ ESX/ ESXi ESX/ ESXi ESX/ ESXi ESX/ ESXi ESX/ ESXi ESX/ ESXi ESXi

20 Capacity Planning IBM SmartCloud Monitoring A Deeper Look at Capacity Analytics

21 Why is Capacity Management Important? Helps consolidate and reduce costs o Reduces HW and labor costs o Reduces number of physical servers required to run workloads o Reduce number of required licenses o Increase VM density and increase Cloud ROI o Predict how many more customers / VMs can be serviced Helps ensure application availability and reduce risk o Are any resources overloaded? When will physical resources reach their limits? o Have there been any significant changes in my environment between two weeks? o Identify trends to predict bottlenecks or free space and balance workloads o Ensure supply can meet demand o Ensure technical and business policies are met to reduce risk Helps optimize resource utilization o Right size virtual machines and allocate based on usage, over-commit within known risk limits o Pack VMs on the infrastructure to optimize resources

22 Planning Analytics Benchmarking data Business and Technical policies Plan Recommendation Optimization Engine to size and place VMs (minimize systems, license, balance) Usage profiles, workload relationships Workload Characterization - Establish patterns using historical data - Capture workload attributes to enable optimization policies Custom Tags enhance Config Profiles and workload relationships Capacity Planning Database Copy, Federate Storage Hypervisors Network Platforms Servers

23 Planning Scenarios 1. An IT Admin wants to consolidate an existing environment and optimize the use of physical resources 1. A Capacity Planner performs what-if analysis to accommodate future VM requests 2. A Capacity Planner applies business and technical best practices to create a plan
