Do's and Don'ts for Monitoring and Investigating Issues with NDB

Task Do Not Do This (Incorrect Approach) Do This Instead (Correct Approach)
Set Up Alert Policies "Use generic alert policies that are too broad or not tailored to the specific needs of your NDB environment." "Define specific alert policies based on the critical components and operations of your NDB environment, such as database availability, performance, and storage usage."
Configure Notifications "Fail to configure notifications or set them to go to a single recipient, assuming that one person will always handle all alerts." "Configure notifications to send alerts to multiple recipients or distribution lists to ensure timely response, even if one person is unavailable."
Monitor Alerts Dashboard Regularly "Ignore the alerts dashboard, assuming that any critical issues will automatically be brought to your attention by users or external stakeholders." "Regularly monitor the alerts dashboard to proactively identify and address issues before they impact users or business operations."
Collect Logs Systematically "Collect logs only after a significant issue occurs, assuming that logs are not useful for routine monitoring and maintenance." "Implement a policy to regularly collect logs and use them for routine monitoring and analysis to detect potential issues early."
Use Alerts to Trigger Actions "Set alerts but fail to associate them with any follow-up actions, assuming alerts will automatically lead to resolution." "Create action plans for each alert type to ensure that there are clear steps to follow when an alert is triggered."
Investigate Issues Promptly "Delay investigation of alerts or issues, assuming that minor alerts will resolve themselves without intervention." "Investigate all alerts promptly, prioritizing based on severity and potential impact, to prevent minor issues from escalating."
Audit and Update Alert Policies Regularly "Set alert policies once and never review or update them, assuming that initial settings will always be sufficient." "Regularly review and update alert policies to ensure they remain effective and aligned with the current state and needs of the NDB environment."
Analyze Logs for Root Cause "Ignore logs after an issue is resolved, assuming there is no value in understanding the root cause once the problem is fixed." "Always analyze logs thoroughly to identify the root cause of issues, even after resolution, to prevent recurrence."
Document Alerts and Resolutions "Rely on memory or informal communication to track alerts and their resolutions, assuming that detailed records are unnecessary." "Maintain detailed documentation of all alerts, their analysis, and resolutions to support future troubleshooting, audits, and continuous improvement."
Enable Alert Escalation "Set all alerts to the same severity level or fail to set escalation policies, assuming that all alerts are equally critical." "Define escalation policies for different alert levels to ensure critical alerts receive immediate attention while less critical alerts are addressed appropriately."

Explanations for Correct Choices:

  1. Set Up Alert Policies:

    • Specific alert policies allow you to focus on the most critical components and operations, ensuring you monitor what matters most for your environment's health.

  2. Configure Notifications:

    • Properly configured notifications ensure that alerts reach the right people promptly, reducing response times and preventing potential issues from escalating.

  3. Monitor Alerts Dashboard Regularly:

    • Proactively monitoring the alerts dashboard helps you catch and resolve issues before they become major problems, minimizing the impact on users and business operations.

  4. Collect Logs Systematically:

    • Regular log collection allows for ongoing analysis, helping to identify potential issues early and maintain a historical record for future reference.

  5. Use Alerts to Trigger Actions:

    • Associating alerts with specific action plans ensures that there is a clear response protocol for every alert, improving efficiency and effectiveness in issue resolution.

  6. Investigate Issues Promptly:

    • Prompt investigation of alerts prevents minor issues from escalating into more significant problems, reducing downtime and service disruption.

  7. Audit and Update Alert Policies Regularly:

    • Regular reviews of alert policies ensure they remain relevant and effective as your environment changes over time.

  8. Analyze Logs for Root Cause:

    • Analyzing logs to identify the root cause helps prevent recurring issues and improves the overall stability and reliability of the NDB environment.
