2 OVERVIEW Providing the right level and depth of monitoring is key to ensuring the effective operation of IT systems. This is especially true for ecommerce systems like Magento, where downtime and poor performance have immediate and profoundly negative impacts on revenues and brand perceptions. Even more disturbing is the fact that these impacts can be far reaching, impacting customer purchase behavior for months or even years as the following statistics indicate : 47% of consumers expect a website to load in 2 seconds or less. 40% will abandon a website that takes more the 3 seconds to load. A 1 second delay (or 3 seconds of waiting) decreases customer satisfaction by 16%. 79% of shoppers who are dissatisfied with website performance are less likely to buy from the same site again. 44% of online shoppers will tell their friends about a bad experience online. Given the direct and immediate correlation between ecommerce website performance, business performance and customer lifetime value, the level of monitoring of ecommerce websites must go far beyond the monitoring of system vitals. It must go deep enough to uncover issues that may affect the customer experience and ideally uncover these issues before they ever impact customers. Tenzing is a managed hosting provider that specializes in ecommerce hosting solutions for Magento. Our position in the Magento ecosystem gives us a unique vantage point on the impacts of performance on ecommerce success. The range of customers that we serve and our experiences with our customers have impressed upon us the importance of advanced monitoring, so much so that we have invested in technologies and developed specific best practices to ensure the success of our customers ecommerce initiatives. This whitepaper describes our approach to advanced monitoring, one we hope you will find valuable in your ecommerce initiatives. 79 % of shoppers who are dissatisfied with website performance are less likely to buy from the same site again.

3 A Success-Based Approach to Monitoring A Success-Based Approach to Monitoring Monitoring, at its heart, is an exercise in transforming system data into critical insights, providing those insights to key stakeholders, at which point those key stakeholders take action to deliver measurable customer value. In our experience failures usually arise from a few key missteps: Poor data collection. This key driver of failure can take several forms, from collecting too little data to collecting too much data to collecting the wrong data. All lead to the same result, namely erroneous insights that lead to bad business decisions. Inaccurate insights. Inaccurate insights can be driven by a variety of sources, including observer bias and lack of proper context. Wrong stakeholder. Even the most insightful, impactful observation can become meaningless in the hands of the wrong stakeholder. Getting insights into the right hands must be a top priority. Our approach to monitoring Magento ecommerce environments is rooted in an approach that ensures that we re continually collecting the right information (i.e. data that accurately reflects the customer experience), drawing the right conclusions from that data (typically in partnership with our customers) and delivering these insights to the right business stakeholders to deliver measurable benefits. We ll discuss each of these elements of our approach in some detail, describing best practices designed to ensure optimal performance of the Magento platform. 3 Dallas Kelowna London Toronto Vancouver

4 Proper Data Collection for Managing User Experience As alluded to earlier, to properly track impacts to the customer experience one must be prepared to go beyond just checking for system vitals like memory, CPU, and I/O consumption. These indicators are necessary, but at best serve to rapidly indicate when a problem is already occurring. One must go deeper and collect performance data at the platform level (i.e. Magento and the underlying MySQL or Percona Server database) and at the code level. One must also marry these performance statistics to approaches rooted in measuring the customer experience through techniques like synthetic and business transaction monitoring. When combined with other approaches like periodic load testing, these monitoring techniques provide a holistic view of ecommerce website performance from the customers perspective. Most importantly, they enable organizations to identify and remediate performance bottlenecks before they ever impact customers. Figure 1 illustrates how these different types of monitoring work together to proactively deliver a remarkable customer experience. 7 Global Intrusion Monitoring 1 System Vitals Monitoring Basic system availability and performance monitoring (i.e. memory, CPU, and storage consumption.) 3 Platform Monitoring Application monitoring of the Magento platform and MySQL or Percona database. 5 Synthetic /Real User Monitoring Monitoring the customer experience. Layers of monitoring required to deliver a remarkable customer experience. Customer Experience 4 Code Level Monitoring Code level monitoring of PHP based classes. 6 Load Testing External load that mimics customer behavior to test thresholds of performance degradation. 2 Critical Systems Protection Host IDS/IPS + critical OS file monitoring/protection. Figure 1: Layers of monitoring required to deliver a remarkable customer experience What follows is a detailed description of each of these types of monitoring and performance management tools, how each is used to deliver value individually, and finally how the combination of monitoring and load testing techniques drive proactive system performance on the Magento platform. It is important to keep in mind that, while the following solutions serve specific functions, the end goal of a holistic monitoring strategy is to ensure the solution performs consistently, supporting an excellent customer experience across endpoints. Gaining insight into events that affect user experience before they occur, and preventing experience degradation is the key objective in a solid monitoring strategy.

5 System Vitals Monitoring System vitals monitoring is the most basic layer of monitoring, providing insight into server availability, performance and capacity. At Tenzing, we utilize technology from Uptime Software, Inc. to provide realtime system monitoring of your Magento environment, along with a single pane of glass interface in which to manage and review this data. This system provides critical alerting for a variety of system resources and keeps your internal teams and your Tenzing support team informed of any changes to the status of your servers that might impact the availability and performance of your Magento solution. In addition, it also assists with capacity planning by collecting and trending historical performance data. Monitoring Dashboard and Charts Tenzing leverages Uptime Software s graphical system monitoring interface to deliver a comprehensive dashboard view of system performance. Uptime has a unified, comprehensive, and scalable IT dashboard for monitoring that is easy to use and fast to deploy.the dashboard intuitively delivers a snapshot of the health of your systems. It proactively monitors all physical servers, virtual machines, network devices, applications, and services. Using Uptime, the Tenzing operations and support teams are able to quickly see and react to core performance issues with regard to resources that may compromise the availability of your system. This enables you to save time and money and keep your business running smoothly. Figures 2-4 provide examples of the variety of charts and views that are available into system performance.

6 Critical Systems Protection In addition monitoring system vitals at the host level, Tenzing also leverages full hostbased intrusion detection and prevention technologies. At this level, critical operating system files are monitored for changes in real-time, including who made the change and what changed with the file. Granular intrusion protection policies are implemented, providing protection against server incursion and compromise, including zero day threats, while providing real-time visibility into compliance. Magento Application Monitoring Magento application monitoring consists of sets of custom monitors that were developed by Tenzing for monitoring key vitals of a Magento system. Magento application monitoring alerts on different application components on your Magento system such as Apache and Nginx web server performance, PHP processes, and interserver communications. Database Monitoring The MySQL or Percona Server database is at the heart of your Magento solution. Optimal performance takes careful consideration, scrupulous oversight and highly specialized expertise in a variety of areas including storage management, backup and recovery management and data management. parameters, we also review these key metrics with customers on a monthly basis. During these meetings we discuss and plan mitigation strategies that ensure that our customers database environments performance at peak performance. Synthetic Transaction Monitoring Synthetic monitoring proactively tests your web, non-web, mobile, streaming and cloud-based applications to validate user action/ response functionality across the user experience. Transactions can be executed matching the profile and perspective of your end users, including: Geographic distribution Browser and device types (Chrome, IE, Firefox, mobile devices/ browsers) Internet connection types (i.e. broadband, dial-up, mobile, etc.) Content types (i.e. static web content, dynamic web content, and streaming media) The goal of synthetic transaction monitoring is to accurately gauge the true customer experience generated by your system under a variety of real-world conditions from your customers perspective. To this end, synthetic transaction monitoring runs automated synthetic transactions against your ecommerce site from multiple geographic locations, and monitors the health and performance of these transactions against baseline goals that you define. Any observed failure or unacceptable slow response time is then logged and reported, allowing us to identify and help address failures that may affect customer experience while on the site. Customers are provided with a detailed dashboard to analyse and help manage service levels and resources as measured against our customers customer experience goals. The following is a list of key performance metrics that should be tracked and analyzed on an ongoing basis to ensure the optimal performance of your underlying database: Database Availability Error log monitoring Database failed jobs Database performance: Inefficient SQL Blocking locks Database backup assurance Partition monitoring Replication monitoring Cluster monitoring Log shipping monitoring Figure 4: Synthetic transaction overall performance view indicating 100% uptime In addition, it is critically important to periodically review these metrics with your hosting provider to ensure you stay ahead of issues. For example, at Tenzing apart from daily monitoring of the data base Figure 5: Individual transaction performance over time Monitoring Best Practices for Magento 6
