    VMware monitoring must haves VMware monitoring must haves Presentation Transcript

    • VMware performance monitoring - The Must Haves
      • OpManager Marketing Team
    • Agenda
      • About ManageEngine
      • Virtualized vs. Physical Server Monitoring
      • VMware Performance Monitors
      • Performance Management – the Essentials
      • OpManager’s VMware Monitoring
      • Discussion
    • About ManageEngine ManageEngine Software is used by over 40,000 customers including 3 out of every 5 Fortune 500 companies Vendor Landscape
    • ManageEngine – IT Management Portfolio ManageEngine is the only IT management vendor focused on bringing a complete IT management portfolio to the mid sized enterprise
    • Virtualized vs. Physical Server Monitoring Pros Cons Shared Resources Ideal resource utilization, quickest ROI Problem in one VM might affect the other VMs in the Host Dynamic Servers 100% server uptime Tracking of VMs to corresponding Host Easy Provisioning Server provisioning within minutes VM Sprawl – Zombie VMs eating-up resources
    • Performance Monitoring – the Fundamentals
    • VMware Performance Monitors
      • CPU
      For Hosts & VMs : CPU Utilization (%), CPU Usage(MHz) On Individual VMs : CPU Used (ms), CPU Ready time (ms), CPU Wait time (ms)
      • CPU Ready time : VM ready-to-run but no physical CPU free
      • CPU Wait time : VM blocked on I/O
      • Rule of thumb: CPU ready time >20%, needs investigation
      • High %ready + high %used, very probable CPU over-commitment
      • EMA benchmark report – Avg. performing enterprise has physical CPU utilization of 45%, best performing enterprise has it at 70%
      • Memory
      For Hosts & VMs - Memory Utilization (%)/ Usage (KB), Memory Active (KB), Used (KB) & Overhead (KB) On Hosts - Swap In/ Out (KB), Swap used (KB), Swap in/ Out rate (KB/s), memory shared (KB), shared common(KB) On individual VMs - Memory Balloon (KB), Shared(KB) & Swapped (KB)
      • Rule of thumb: >1MB/s swap in or swap out rate, memory over-commitment, reallocation needed
      • Memory shared – shared common = machine memory savings (KB)
      • EMA report benchmark – Avg. performing enterprise has memory utilization of 60%, best performing enterprise 80%
      VMware Performance Monitors
      • Hard Disk
      For Hosts & VMs - Disk I/O Usage (KBps), Disk Read & Write Speed (KBps)/ Disk Read & Write Speed Requests (number), Disk Bus Reset On Hosts - Disk Read/ Write Latency (ms), Disk Command Abort, Device, Kernel & Command Latency (ms)
      • When Command Latency (total latency for one command) > 50 ms, high latency, needs investigation
      • If Kernel Latency (Average latency in vmkernel) very low ~0, command is not queuing in the kernel. If also Device Latency (Average latency at device) is 0, disk has connectivity issues.
      • Study Reads and Writes, CPU usage side-by-side
      VMware Performance Monitors
      • Network Interface Card
      For Hosts & VMs - Packets Received/ Transmitted (packets/sec), Network Usage (KBps), Network Received/ Transmitted Speed (KBps)
      • Are packet rate/ bandwidth at expected levels?
      • Are the VMs sharing one physical NIC?
      • EMA benchmark report – Avg. performing enterprise has NIC utilization of 30-40%, best performing enterprise have it at 70-90%
      VMware Performance Monitors
    • Performance Management – the Essentials
      • Quick views - of problem areas e.g. top VMs by CPU Ready time
      • Thresholds - assigned by default for important metrics
      • Notifications & Alarm Management - should easily gel with the existing IT mgmt procedures
      • Side-by-side reports – a single dashboard having multiple metrics; VMware specific and those of the physical hardware for quick troubleshooting
      • History Reporting
    • OpManager’s VMware Monitoring
      • Supports ESX 3.5, ESX3.5i, ESX4 & ESX4i
      • Uses native VMware APIs: Agent-less, in-depth monitoring, zero configurations
      • Over 70 deep metrics, with daily/weekly/monthly history reports; 15+ monitors with default thresholds
      • Automatically maps VMotioned VMs to the corresponding Hosts
      • Inbuilt with OpManager – no extra plug-in or download required
      • Exclusive dashboards & monitors for MS SQL, MS Exchange & Active Directory
