Proactive Performance Management helps by –
Identifying performance issues early in the design
Validate suitability of your application architecture for your documented NFR’s
Validate your application capacity requirements for the documented NFR’s
Advocates early SVT to identify potential bottlenecks early in the build and development cycle
Reduces potential for major rework later in the program
Advocates using modelling techniques to predict performance impact for growing workload
Txn Performance
- Response Times, etc.
Application Performance – Operations/Sec, Messages/Sec,
Transactions/Sec, etc.
Infrastructure Performance – CPU Utilization, Memory Utilization, Disk IOPS, etc.
Network Performance – Packet Loss, Jitter, Packet Re-ordering, Delay, etc.
Holistic View of Performance
What Is Performance Monitoring
Monitoring can be defined as a set of processes whose objectives is to proactively track various relevant metrics so as to prevent breach of agreed Service Level Agreements
Monitoring is generally achieved using a combination of process, tools and people capability (Required to efficiently deliver the monitoring service)
Monitoring can be looked at from different perspectives:
Infrastructure Monitoring
Application Monitoring
Application Diagnostics
Business Transaction Monitoring
End User Monitoring
Real User Monitoring
Monitoring requires the capture and correlation of relevant performance metrics across the different application, infrastructure and network tiers
Like everything else in Performance Engineering, an effective monitoring strategy requires a combination of tools, processes and people capability
Why Is Performance Monitoring Important
Performance Monitoring is important for the following reasons –
If you don’t measure performance you can’t manage it and if you don’t manage it you probably don’t care
Monitoring is essential to help you capture relevant performance metrics across the various different tiers which then helps you track your SLA’s
Monitoring of relevant performance metrics across the various tiers (application, infrastructure, network) helps you correlate performance issues across the various tiers and identify performance bottlenecks
Monitoring helps you measure your applications ability to meet your defined Non Functional Requirements
Monitoring helps capture relevant business workload metrics & infrastructure workload metrics for purposes of Performance Modelling & Capacity Management
Monitoring generates performance metrics which can then be used for root cause analysis when things go pear shaped in production
What is Application Performance Management
Performance Monitoring Process
Understand Business Objectives & Program
Goals
Understand Non Functional Requirements
Understand the Application Stack
Identify relevant Monitoring tools for
Infrastructure, Network, Application &
Transaction monitoring
Identify relevant Infrastructure & Network
Performance Metrics
Identify relevant Application Performance
Metrics
Identify relevant Transactional
Performance Metrics
Configure and store Performance metrics
data in a CMDB
Configure Single Pane of Glass View to provide
Real Time View of Performance across
Tiers
Collect & store relevant metrics for purposes of Modelling & Capacity
Management
Analyse monitoring data in real time & correlate
performance across different tiers
Report Application Performance in terms of Business Metrics & IT
Metrics
Challenges involved in Performance Monitoring
Glut of tools combined with numerous vendor buzz words that ends up confusing customers
Lack of mature processes within the enterprise to measure, track and manage performance
Lack of understanding of relevant performance metrics to measure, track and manage performance
Challenge convincing the application teams on the importance of measuring and tracking Business Workload
Challenges capturing relevant infrastructure performance metrics for virtualized applications
Challenges capturing Business Workload data from production since applications are rarely designed to log Business Workload metrics
Providing a single pain of glass by correlating performance metrics across different tools (network, infrastructure, application) and application tiers
Finding tools that can help you track application performance from the client browser down to the database server
Deliverables – Performance Monitoring
Performance Monitoring Approach that defines -
Infrastructure Performance Metrics
Metrics for Business Workload
Application Performance Metrics
Transactional Performance Metrics
Tools required for monitoring relevant performance metrics across different application tiers
Integration between existing tools to provide a Single Pane of Glass view
Frequency of data collection for Performance Modelling & Capacity Management
