Monitoring and alarm is an important part to ensure high reliability, high availability and high performance of CVM. This document provides an overview of the monitoring and alarm features provided for the CVM.
Overview
CVM monitoring and alarm is a management tool for real-time monitoring of CVMs. The monitoring and alarm feature can display the most comprehensive and detailed monitoring data, extracting key indicators from the CVM in real-time and presenting them in the form of monitoring charts.
To provide you with a comprehensive understanding of your CVM's resource usage, performance, and health status.
It also supports setting custom alarm thresholds and sending notifications based on your custom rules.
Basic Features
The console provides access to the following functionalities for CVM monitoring and alarm:
| Module | Capability | Main Feature |
|---|---|---|
| Monitoring Overview | View the overall monitoring status of cloud services. | Provide an overview of the overall situation, alarm situation, and overall monitoring information. |
| Alarm Management | Support for user custom alarm thresholds | Currently supports CVM alarm settings |
| Cloud Services Monitoring | View detailed monitoring status of cloud services. | Current CVM monitoring view |
| Custom Monitoring | View user-defined monitoring metric data. | Provide custom metric reporting and monitoring alarm services. |
| Traffic Monitoring | Monitor traffic usage. | View overall user bandwidth information. |
For more information, please see the Basic features of cloud monitoring.
Application Scenario
- Daily management scene: Log in to the cloud monitoring console to view the running status of each cloud monitoring.
- Timely handling of exception scene: When the monitoring data reaches the alarm threshold, an alarm message will be sent to notify you promptly, allowing you to acquire exception notification and check the cause of the exception.
- Timely scale-out scene: After the alarm rules for monitoring items such as bandwidth, connection counts, disk usage, etc. are set, you can conveniently understand the current status of your cloud service and receive timely alarm notifications to scale out your service capacity as the business volume increases.
Monitoring Content
To monitor instance performance benchmarks, you should monitor at least the following monitoring items:
| Monitoring Items | Monitoring Metrics |
|---|---|
| CPU Utilization | cpu_usage |
| Memory Utilization | mem_usage |
| Private Network Outbound Bandwidth | lan_outtraffic |
| Private Network Inbound Bandwidth | lan_intraffic |
| Outbound Bandwidth of Public Network | wan_outtraffic |
| Public Network Inbound Bandwidth | wan_intraffic |
| Disk Usage Rate | disk_usage |
| Disk I/O Waiting Time | disk_io_await |
Monitoring Data
- Monitoring interval: Currently, cloud monitoring provides multiple monitoring data statistical granularities of 1 minute, 5 minutes, 1 hour, and 1 day. The CVM can support 1 minute monitoring granularity, that is, data is counted every 1 minute, and the default interval is 5 minutes.
- Data storage: Monitoring data with 1 minute, 5 minutes and 1 hour granularity is stored for 31 days, and monitoring data with 1 day granularity is stored for half a year.
- Alarm display: The data is displayed in easy-to-read charts. The console integrates the monitoring data of all products, which is more conducive to users to obtain a holistic operation overview.
- Alarm settings: You can set threshold values for monitoring metrics, and when the conditions are met, alarm messages will be sent promptly to the concerned group.
