Monitoring Standards

Good management is essential when developing highly effective teams. DevOps Research and Assessment Research shows that monitoring solutions, alongside many other techniques, positively contribute to continuous development. Monitoring is tools and technical solutions that enable a company to monitor and understand the system state. Monitoring is a process of analyzing metric information. Observability means tools to debug systems in real-time. Observability involves looking at patterns or features which have not previously been identified.

To effectively monitor an application migration, you should

1. Establish a baseline of performance and activity before the migration. This will help you to determine whether there are any significant changes in performance or activity after the migration has been completed.

2. Document all steps taken during the migration process. This will help you to troubleshoot any issues that may occur during or after the migration.

3. Monitor the performance of the migrated application. This will help you to identify any issues that may have an impact on the end-user experience.

4. Log all errors that occur during or after the migration. This will help you to identify and address any potential issues with the migrated application.

5. Regularly review the logs generated by the monitoring tools in use. This will help you to identify any trends or issues that may need to be addressed.

By following these guidelines, you can ensure that your organization's monitoring standards are adhered to during application migration. This will help to minimize the impact of the migration on your IT infrastructure and operations.

Common pitfalls of implementing monitoring and observability

There are a few common pitfalls that can occur when implementing monitoring and observability into your DevOps practice. These include:

1. Failing to set up proper baselines for comparison. Without establishing accurate baselines, it can be difficult to determine whether any changes in performance or activity are due to the migration, or are simply normal fluctuations.

2. Failing to document all steps taken during the migration process. This can make troubleshooting any issues that may occur difficultly, and can also lead to confusion among team members.

3. Failing to monitor the performance of the migrated application. This can prevent you from identifying and addressing any issues that may have an impact on the end-user experience.

4. Failing to log all errors that occur during or after the migration. This can make it difficult to identify and address any potential issues with the migrated application.

5. Failing to review logs regularly. This can prevent you from identifying any trends or issues that may need to be addressed.

By avoiding these common pitfalls, you can help ensure that your organization's monitoring and logging standards are implemented effectively and efficiently. This will help to minimize the impact of the migration on your IT infrastructure and operations.
