Performing root cause isolation of impacted services in your environment
This use case describes how you can use BMC Helix AIOps to analyze service health and determine root cause isolation information for the impacted services.
Susan is an operator for the APEX Global IT Train Ticketing System. The train ticketing system provides a portal for booking and managing train reservations. The train ticketing system is based on a microservices architecture.
Susan plans to monitor a large number of services of the train ticketing system by using a single console. Susan faces the following challenges in her IT operations environment:
- Monitoring the health of a large number of services from different sources is time-consuming, tedious, and complex task.
- Viewing large number of events from multiple sources resulting in event noise.
- Meeting SLAs in a complex environment requires quick analysis of issues.
- Correlating data from a disparate set of solutions is difficult.
Therefore, Susan needs an effective solution to monitor services from all the sources by using a single console to quickly identify the impacted services, determine the probable causes of the impact, and diagnose and resolve the issues in a short time.
Susan can find answers to most of her challenges by using BMC Helix AIOps. Susan can determine the root cause isolation information for an impacted service by:
- Using a ranked list of the most likely events that caused the impact.
- Visualizing the relationship between a discovered business service and nodes of the service
- Analyzing the events and change requests that are causing the impact
- Viewing and understanding the anomalies or abnormalities from the metrics data associated with the causal events
Therefore, Susan decides to use BMC Helix AIOps to achieve her business goals.
Susan requests the tenant administrator Tim to complete the following activities so that she can start monitoring the train ticketing application:
- Register and activate a BMC Helix AIOps account.
- Create an operator role for Susan to log in to BMC Helix AIOps.
- Enable the AIOps root cause isolation feature. For more information, see Enabling the AIOps features.
