monitoring

 visualize using Grafana:

  1. CPU Usage: Monitor the utilization of CPU resources across different hosts or containers to identify potential bottlenecks or performance issues.

  2. Memory Usage: Track the usage of memory resources to ensure optimal memory allocation and identify memory leaks or inefficiencies.

  3. Disk Usage: Monitor disk space usage on servers or storage systems to prevent disk space-related issues and plan for capacity expansion.

  4. Network Traffic: Visualize incoming and outgoing network traffic to identify network congestion, anomalies, or potential security threats.

  5. HTTP Requests: Monitor HTTP request rates, response times, and status codes to gauge the performance and availability of web services and applications.

  6. Database Queries: Track database query execution times, throughput, and error rates to optimize database performance and identify slow or problematic queries.

  7. Latency Metrics: Monitor latency metrics such as request/response times for different services or components to ensure acceptable performance levels and detect performance degradation.

  8. Error Rates: Visualize error rates and error counts for applications, services, or infrastructure components to identify issues and prioritize troubleshooting efforts.

  9. System Metrics: Monitor system-level metrics such as load average, uptime, and process counts to gain insights into overall system health and performance.

  10. Custom Application Metrics: Instrument your applications with custom metrics related to business logic, user activity, or specific application components to gain visibility into application performance and behavior.

  11. Container Metrics: Monitor container-level metrics such as CPU usage, memory usage, and network activity to optimize resource allocation and troubleshoot containerized applications.

  12. Service Health Checks: Visualize service health checks and availability metrics to ensure that critical services are running as expected and detect service outages or disruptions.

  13. Infrastructure Provisioning Metrics: Track metrics related to infrastructure provisioning, such as server provisioning time or cloud resource allocation, to optimize resource utilization and improve deployment processes.

  14. Security Metrics: Monitor security-related metrics such as failed login attempts, unauthorized access attempts, or suspicious network activity to detect and mitigate security threats.

  15. Business Metrics: Visualize business-related metrics such as sales revenue, customer acquisition rates, or user engagement metrics to track business performance and inform decision-making.



r Service Level Objectives (SLOs) and Service Level Indicators (SLIs) is crucial for aspiring Site Reliability Engineers (SREs). Here are some tips to help you learn and master these concepts:

  1. Understand the Fundamentals: Start by gaining a clear understanding of what SLOs and SLIs are and their significance in measuring system reliability and performance. Learn about the relationship between SLIs, SLOs, and Service Level Agreements (SLAs).

  2. Study Relevant Documentation: Familiarize yourself with industry-standard resources, such as Google's Site Reliability Engineering book, which provides comprehensive explanations of SLOs and SLIs. Additionally, explore documentation and case studies from other reputable sources.

  3. Practice with Real-world Examples: Look for real-world examples of SLOs and SLIs used by companies in various industries. Analyze how these metrics are defined, measured, and monitored to gauge system reliability and performance.

  4. Hands-on Experience: Gain practical experience by working on projects or simulations where you define and monitor SLOs and SLIs for different systems or applications. Experiment with different metrics and thresholds to understand their impact on system behavior.

  5. Use Monitoring Tools: Explore popular monitoring tools and platforms that support defining and tracking SLIs and SLOs, such as Prometheus, Grafana, Datadog, or Stackdriver. Practice configuring these tools to collect relevant metrics and set up alerts based on predefined thresholds.

  6. Collaborate with Peers: Engage with peers, mentors, or online communities specializing in SRE or DevOps practices. Discuss concepts, share experiences, and seek advice on defining and monitoring SLOs and SLIs effectively.

  7. Learn from Failure Analysis: Study post-mortem analyses of incidents or outages to understand how failures relate to SLO violations and SLI deviations. Analyze how improvements in monitoring and alerting could have prevented or mitigated these incidents.

  8. Continuous Improvement: Treat SLOs and SLIs as living documents that evolve over time. Continuously evaluate and refine your metrics based on changing business requirements, user expectations, and system behavior.

  9. Stay Informed: Keep up-to-date with advancements in SRE practices, monitoring tools, and industry trends related to reliability engineering. Attend conferences, webinars, or workshops to learn from experts and stay informed about best practices.

  10. Document Your Learnings: Document your experiences, lessons learned, and best practices for defining and monitoring SLOs and SLIs. Create guides or tutorials to share your knowledge with others and reinforce your understanding of the concepts.

Service Reliability Engineer (SRE): Primarily responsible for improving the reliability of services through collaboration with development, proactive monitoring, and optimization of redundancies in operations. SRE is an integral part of modern cloud development teams who are involved in proactive testing, observability, service reliability, and speed Shift left security – from DevOps to DevSecOps With a move from just a few releases a year to weekly feature releases, security can no longer be ensured manually. Security needs to be part of the DevOps pipeline and be automated. There are plenty of security tools out there from various vendors than can integrate with the pipeline. The key things to be addressed in a DevSecOps pipeline include security tools that address the following. Securing cloud-native development and operations Securing the DevOps pipeline involves catching security errors early in the cycle and addressing the vulnerabilities of deployable artifacts, as well as perfo...
