- By identifying root causes for application performance using\u202fmachine learning<\/span>\u00a0techniques<\/span>,\u00a0<\/span>organizations\u00a0<\/span>can focus on the right set of areas in which\u202fto take action. Predictive analytics\u00a0<\/span>can then<\/span>\u202fstudy the characteristics of the various attributes within each cluster<\/span>\u00a0that\u00a0<\/span>can provide deep insights into what\u202f<\/span>changes need to<\/span>\u00a0<\/span>be\u00a0<\/span>ma<\/span>d<\/span>e to achieve ideal performance and avoid specific bottlenecks.<\/span>\u00a0<\/span><\/li>\n<\/ul>\n
\n- Monitor\u202fapplication health in real<\/span><\/b>–<\/span><\/b>time<\/span><\/b>\u00a0<\/span><\/li>\n
- Performing real-time monitoring of application health via multi-variate machine-learning (ML) techniques allows\u00a0organizations<\/span>\u00a0to catch and respond to\u00a0<\/span>the<\/span>\u202fdegradation of application health in a timely manner. Most applications rely on multiple services to\u202fcapture the true health of the application. The data might consist of configuration data, application logs, network logs, error logs, performance logs and more.\u00a0<\/span>Predictive analytics models can<\/span>\u00a0analyze the past data during a time in which the application was in a good state<\/span>\u00a0and subsequently\u00a0<\/span>identify whether the incoming data exhibits normal behavior or not.<\/span>\u00a0<\/span><\/li>\n<\/ul>\n
\n- Predict\u00a0<\/span><\/b>user load<\/span><\/b>\u00a0<\/span><\/li>\n
- Predictive analytics can help in predicting the user load by analyzing the past data. Organizations can use this data to better prepare in order to handle the predicted user load and provide experience\u00a0assurance\u00a0<\/span>which would help in reducing customer churn. This data can also help the organizations better plan their future IT infrastructure requirements and capacity utilization.<\/span>\u00a0<\/span><\/li>\n<\/ul>\n
\n- Predict application outages before they happen<\/span><\/b>\u00a0<\/span><\/li>\n
- Predicting application downtime or outages before they happen helps perform\u00a0the\u00a0<\/span>needed maintenance on th<\/span>e<\/span>\u00a0application without any downtime. This can save an organization time<\/span>,<\/span>\u00a0money<\/span>, and much more<\/span>. Before an application outage, the IT infrastructure leaves lots of indirect clues hours, or even days, before it dies. The\u00a0<\/span>predictive analytics\u00a0<\/span>model\u00a0<\/span>can\u00a0<\/span>learn those patterns and continue to monitor for similar occurrences, predicting future failures before they happen. With this type of predictive model in place, preventive action\u00a0<\/span>can be taken\u00a0<\/span>at the right time.<\/span>\u00a0<\/span><\/li>\n<\/ul>\n
Applying predictive analytics to forecast application performance<\/span><\/b>\u00a0<\/span><\/p>\nP<\/span>redictive analytics in the area of application performance improvement focuses on three main areas \u2013\u00a0<\/span>Forecasted<\/span>\u00a0User Load,\u00a0<\/span>Response<\/span>\u00a0<\/span>Time prediction<\/span>,<\/span>\u00a0<\/span>and\u00a0<\/span>I<\/span>nfrastructure\u00a0<\/span>A<\/span>ssessment.<\/span>\u00a0<\/span><\/p>\nUser Load<\/span><\/b>\u00a0Prediction<\/span><\/b>\u00a0<\/span><\/p>\nTraditionally organizations have relied on peak user traffic in the past in order to come up with the number of users that might access the application in the future. This model has its own limitations as it does not consider factors such as emergence o<\/span>f<\/span>\u00a0new technologies, change in user behavior and other disrupti<\/span>ve<\/span>\u00a0factors. By using\u00a0<\/span>AI\/ML\u00a0<\/span>predictive analytics<\/span>,<\/span>\u00a0businesses can avoid these pitfalls as\u00a0<\/span>forecasting\u00a0<\/span>models can be built\u00a0<\/span>by analyzing the user behavior in real time<\/span>.\u00a0<\/span>\u00a0<\/span><\/p>\nUsing the data provided by the APM we\u00a0<\/span>have built<\/span>\u00a0a model to predict the number of users who will access the application\u00a0<\/span>six<\/span>\u00a0months<\/span>\u00a0into the future.\u00a0<\/span>We used\u00a0<\/span>the hourly monitoring data from production monitoring for the past 2 years<\/span>\u00a0as input to the model.\u00a0<\/span>We found that the accuracy provided by the model was low\u00a0<\/span>when we used classification and regression models\u00a0<\/span>due to missing data and data imbalance.\u00a0<\/span>\u00a0<\/span><\/p>\nT<\/span>he data\u00a0<\/span>was normalized\u00a0<\/span>to handle missing data and data wrangling\u00a0<\/span>performed\u00a0<\/span>to mitigate the data imbalance and fed to a neural network<\/span>.
