Cloud monitoring through the provision of analytic dB disk rated capacity, disk used capacity, disk usage 3 messages, help Users get analytic DB Service usage.

When users start using analytic dB services, cloud monitoring automatically begins to monitor them, analytic dB for cloud monitoring You can view monitoring details on the page. You can also set alarm rules on monitoring items so that you receive alarm information when the data is abnormal.

  • Viewing Monitoring Data
    1. Log in to the cloud monitoring console.
    2. Enter the list of analytical database instances that the cloud service monitors.
    3. Click the Instance name or the monitor chart in the operation to go to the monitor details page.
    4. Click the size chart toggle button to toggle the larger image display (optional ).

Alarm service

  • Parameter descriptions
    • Monitoring: Monitoring metrics provided by the analytical database.
    • Statistical Cycle: the alarm system checks if your monitoring data exceeds the alarm threshold for this cycle. For example, to set a memory usage alarm rule, the statistics cycle is 1 minute, an interval of 1 minute checks if memory usage exceeds the threshold.
    • Statistical Methods: Statistical Methods refer to settings that exceed the threshold range. You can set the average, maximum, minimum, count, and value in a statistical method.
      • Average: the average of the monitored data during the statistical cycle. The result is an average of all monitoring data collected in 15 minutes, when this average is greater than 80%, the threshold is exceeded.
      • Maximum: the maximum value of the monitor data during the statistics cycle. The maximum value of monitoring data collected during the statistical cycle exceeds the threshold of 80.
      • Minimum: the minimum value of the monitored data during the statistics cycle. The minimum value for monitoring data collected during the statistical cycle exceeds the threshold of 80.
      • Value: Sum of monitoring data during the statistics cycle. To sum up the monitoring data collected during the statistical period, after sum, more than 80% of results exceed the threshold. Such statistical methods are required for traffic-class metrics.
    • Alarm after several consecutive exceeds threshold: refers to a number of consecutive statistical cycle monitoring items whose values continue to exceed the threshold to trigger an alarm.

      Example: Set CPU usage to more than 80% alarm with a statistical cycle of 5 In minutes, alarm after 3 consecutive times exceeds the threshold, when the first time the CPU usage is detected exceeds 80, no alarm notification will be issued. The second time in 5 minutes to detect CPU usage exceeds 80% and no alarm will be issued. The third probe still exceeds 80% Alarm notification will be issued only when. That is, from the first time the actual data exceeds the threshold to the final alarm rule, the minimum time required is statistical cycle X (number of consecutive probes-1) = 5 x (3-1) = 10 minutes.

  • Set alarm rules
    1. Log in to the cloud monitoring console.
    2. Enter the list of analytical database instances that the cloud service monitors.
    3. Click the alarm rule in the instance List action to enter the alert Rule Page for the instance.
    4. Click new alarm rule in the upper-right corner of the alarm Rule Page to create an alarm rule based on the parameter.
