Monitoring and Alarm
Monitoring and alarm management
After clicking "Instance Name" in the "Instance List" and selecting "Monitoring" on the left-hand side of the page, you can see this Baidu AI Cloud database RDS instance's machine-level and database instance-level monitoring trend chart.
Baidu AI Cloud database RDS Monitoring trend chart includes CPU occupancy rate, disk usage rate, memory usage rate, network interface card (NIC) traffic, number of requests, number of links, and maximum transaction execution time.
Add alarm policy and alarm action
Click "Alarm Details" on the figure above to enter the "Alarm Management" page, where you may click "Add Policy" to add an alarm policy.
On this page, you may add policy name and select monitoring items, statistical cycle, statistical method, and threshold, in addition to setting "Alarm after User-defined Repetitions". Also, you may add an alarm action to select the response actions in case of anomalies, insufficient data, and the system's return to normal. For details on alarm management, see BCM Operations Guide Manage Alarm
Monitoring items and implications
Baidu AI Cloud database RDS supports monitoring of the following resources. See table below for details:
| Monitoring Items | Description | Monitoring Frequency | Monitoring Cycle |
|---|---|---|---|
| CPU occupancy rate | CPC usage rate of the instance (excluding the occupancy by the operating system). | Frequency: 60s/time, cycle: 1 hour, 6 hours, 1day, 7 days, 14 days, and 40 days | 40 days |
| Disk usage rate | Percentage of disk space for instance to total disk space | Frequency: 60s/time, cycle: 1 hour, 6 hours, 1day, 7 days, 14 days, and 40 days | 40 days |
| Means the memory usage rate | Percentage of memory for instance to total memory | Frequency: 60s/time, cycle: 1 hour, 6 hours, 1day, 7 days, 14 days, and 40 days | 40 days |
| NIC traffic | Including inflow traffic and outflow traffic. Unit Byte | Frequency: 60s/time, cycle: 1 hour, 6 hours, 1day, 7 days, 14 days, and 40 days | 40 days |
| Number of requests | Including query request times, updating request times, and all SQL times, | Frequency: 60s/time, cycle: 1 hour, 6 hours, 1day, 7 days, 14 days, and 40 days | 40 days |
| Number of connections | Including client links and active threads. | Frequency: 60s/time, cycle: 1 hour, 6 hours, 1day, 7 days, 14 days, and 40 days | 40 days |
| Maximum transaction execution time | Maximum SQL transaction execution time | Frequency: 60s/time, cycle: 1 hour, 6 hours, 1day, 7 days, 14 days, and 40 days | 40 days |
| Slow query | Number of slow queries by users | Frequency: 60s/time, cycle: 1 hour, 6 hours, 1day, 7 days, 14 days, and 40 days | 40 days |
| Master-slave delay | Master-slave instance delay time, unit: s | Frequency: 60s/time, cycle: 1 hour, 6 hours, 1day, 7 days, 14 days, and 40 days | 40 days |
