Importance of GCP Stackdriver Logging & Monitoring
GCP (Google Cloud Platform) Stackdriver Logging & Monitoring is a crucial component of the GCP ecosystem that provides important benefits for monitoring and troubleshooting applications and infrastructure deployed on Google Cloud.
Here are some key reasons why Stackdriver Logging & Monitoring is important:
- Centralized Logging: Stackdriver Logging allows you to collect, search, analyze, and store logs from various services and resources across your Google Cloud environment. It provides a centralized location for all your logs, making monitoring and troubleshooting your applications and infrastructure easier.
- Real-time Monitoring: Stackdriver Monitoring lets you monitor your applications and infrastructure’s performance and health in real-time. It offers various metrics, including CPU usage, memory usage, network traffic, and custom application metrics. With real-time monitoring, you can detect issues promptly and take appropriate actions to maintain system stability.
- Alerting and Notification: Stackdriver Monitoring allows you to set up custom alerts based on predefined conditions or metrics thresholds. When an alert is triggered, you can receive notifications through various channels such as email and SMS or even trigger automated actions using Google Cloud Pub/Sub. This proactive alerting mechanism helps you address issues before they impact your users or services.
- Dashboards and Visualization: Stackdriver Monitoring provides customizable dashboards and visualization tools that allow you to create intuitive and informative displays of your metrics and logs. You can build interactive charts, graphs, and widgets to gain insights into the performance and behavior of your applications. This helps you understand trends, identify anomalies, and make informed decisions based on data.
- Diagnostics and Troubleshooting: Stackdriver Logging & Monitoring offers advanced diagnostic capabilities to investigate and troubleshoot issues. You can analyze logs and metrics together, correlate events, and identify patterns or anomalies that may indicate the root cause of problems. This helps reduce the time to diagnose and resolve issues, improving system reliability and minimizing downtime.
- Integration with Google Cloud Services: Stackdriver Logging & Monitoring seamlessly integrates with other Google Cloud services, such as Google Kubernetes Engine (GKE), Compute Engine, and Cloud Functions. It provides native support for these services, enabling you to gain deeper insights and monitor their specific metrics and logs without additional configuration.
Exploring Stackdriver Monitoring
- Stackdriver Monitoring complements Logging by providing comprehensive monitoring capabilities for your GCP resources.
- It enables real-time visualization, analysis, and alerting of various metrics.
- Dashboards offer a customizable view of your system’s health and performance.
- Code snippet for creating a custom metric and submitting data points using the Stackdriver Monitoring API:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 |
from google.cloud import monitoring v3 client = monitoring v3.MetricServiceClient() project_name = client.project_path(“your-project-id") descriptor = monitoring_v3.MetricDescriptor() descriptor. type = ‘custom. googleapis. com/my_custom metric’ descriptor.metric_kind = monitoring v3.MetricDescriptor.Metrickind. GAUGE descriptor.value type = monitoring v3.MetricDescriptor.valueType.DOUBLE descriptor.description = ‘My-custom-metric’ descriptor = client.create_metric_descriptor(project_name, descriptor) series = monitoring_v3.TimeSeries() series.metric.type = ‘custom.googleapis.com/my_custom metric’ series. resource. type = ‘global’ point = series.points.add() Point.value.double_value = 123.45 now = time. time() point.interval.end_time.seconds = int (now) point.interval.end_time.nanos = int((now - point.interval.end_time.seconds) * 10**9) client.create_time_series(project name, [series]) |
Creating Custom Metrics
- Custom metrics offer flexibility to monitor specific aspects of your applications.
- They allow you to track application-specific error rates, user engagement metrics, or custom resource utilization.
- Code snippet for creating a custom metric in Prometheus format using the Stackdriver Monitoring API:
|
1 2 3 4 5 6 7 8 9 10 11 12 |
from google.cloud import monitoring_v3 client = monitoring_v3.MetricServiceClient() project_name = client.project_path(‘your-project-id') descriptor = monitoring_v3.MetricDescriptor() descriptor. type = ‘custom. googleapis.com/my_prometheus_metric’ descriptor.metric_kind = monitoring_v3.MetricDescriptor.Metrickind. GAUGE descriptor.value type = monitoring_v3.MetricDescriptor.valueType.DOUBLE descriptor.description = ‘My custom Prometheus-style metric’ descriptor. labels. append( Monitoring_v3.LabelDescriptor(key=’label_key’, value type='STRING') ) descriptor = client.create_metric_descriptor(project_name, descriptor) |
Conclusion
With Stackdriver Logging, you can easily centralize and analyze logs, while Stackdriver Monitoring offers real-time visualization and analysis of metrics. By integrating code snippets and practical examples, we’ve highlighted the power of custom metrics in enhancing observability.
