Doris Monitoring Metrics (such as query latency, throughput, and node health status)
What are Monitoring Metrics?
Monitoring metrics are a set of important data points used to describe the performance and stability of a system or application. These metrics typically include query latency, throughput, and node health status.
Query Latency
Query latency is a component of the time taken to execute a query within the system. It reflects the efficiency and speed at which the system processes requests. Higher query latency may indicate insufficient system resources, necessitating an increase in computing or storage resources.
Throughput
Throughput refers to the number of requests that can be processed per unit of time. Higher throughput indicates better system availability and processing capability.
Node Health Status
Node health status refers to the operational condition of a single node (such as a server or database). This metric reflects whether the node is functioning normally and whether it requires a restart or replacement.
Monitoring Tools
Doris provides various monitoring tools that can be used to collect system performance data, including query latency, throughput, and node health status.
Monitoring Results
By using these monitoring tools, system performance data can be collected, analyzed, and processed. This data helps development and operations teams identify and resolve issues, thereby improving system availability and efficiency.
Implementation Methods
Doris offers several methods for implementing the collection of monitoring metrics, including:
- Scheduled Tasks: Use cron jobs or scheduled tasks to optimize routine system operations.
- Real-time Data Streams: Utilize message broker options such as Kafka and RabbitMQ, employing stream events and topics to handle events.
- Monitoring Plugins: Use third-party monitoring plugins (such as Prometheus, New Relic) to collect system performance data.
Comprehensive Analysis
Comprehensive analysis of these metrics can help development and operations teams identify and resolve issues. This can be achieved by utilizing various monitoring tools and methods.
