Cloud monitoring through monitoring the outgoing traffic, incoming traffic, the number of outgoing packets, incoming packets through the elastic public network IP four monitoring items, helps users monitor the running status of the service and enables users to set alarm rules on the monitoring items. User purchases elastic public network After the IP service, cloud monitoring automatically collects data for the above monitoring items.

Monitoring Services

  • Monitoring item description
    Monitoring items Meaning Dimensions Unit Minimum monitor Granularity
    Network inflows bandwidth Average flow to ECs via EIP per second Instance Bits/s 1 minute
    Network outgoing bandwidth The average flow of ECs out of EIP per second Instance Bits/s 1 minute
    Number of incoming packets The average number of packets that flow into ECs via EIP per second Instance Packages/s 1 minute
    Number of outgoing packets The average number of packets per second that ECs flows out through EIP Instance Packages/s 1 minute
  • Viewing Monitoring Data
    1. Log in to the cloud monitoring console.
    2. Enter the list of elastic network IP instances monitored by the cloud service.
    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 elastic  IP.

    • 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 within 15 minutes, when this average is greater than 80. Only when 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. Sum up the monitoring data collected during the statistical period with more than 80% results after the sum That is, the threshold is exceeded. 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: setting up the CPU The use rate is over 80% alarm, with a statistical cycle of 5 minutes and an alarm that exceeds the threshold three times in a row, the first time the CPU is detected When the usage rate exceeds 80%, no alarm notification is issued. If the CPU usage rate exceeds 80% again in the following 5-minute period, it still does not trigger an alert. An alert is reported only if the CPU usage rate exceeds 80% for a third time in the third period. That is, from the first time when the actual data exceeds the threshold to the time when the alert policy is triggered, the minimum time consumed is: the period*(the quantity of consecutive detection times-1) = 5\*(3-1) = 10 minutes.

  • Set alarm rules
    1. Log on to the CloudMonitor console.
    2. Enter the list of elastic network IP instances monitored by the cloud service.
    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.
