Metric Monitoring

The Metric Monitoring page displays metric data of each resource. You can monitor metric values and trends in real time, and create threshold rules for desired metrics. In this way, you can monitor services in real time and perform data correlation analysis.

Procedure

In the navigation pane, choose Monitoring > Metric Monitoring.
Select metrics.
- CN North-Beijing1, CN North-Beijing4, CN East-Shanghai1, CN East-Shanghai2, CN South-Guangzhou, CN Southwest-Guiyang1, CN-Hong Kong, AP-Bangkok, and AP-Singapore: Click Add Metric and select up to 12 metrics by dimension or resource.
  
  A maximum of 100 metric data records can be displayed in a metric graph. If the number of displayed data records exceeds 100, no metrics can be added.
- AF-Johannesburg, LA-Mexico City1, LA-Mexico City2, LA-Sao Paulo1, and LA-Santiago: Search for a component or host and then select metrics, or directly select up to 12 metrics from the resource tree.

Set metric parameters according to Table 1, view the metric graph in the upper part of the page, and analyze metric data from multiple dimensions.

**Table 1** Metric parameters
Parameter	Description
Statistical Mode	Method used to measure metrics. Options: Average, Minimum, Maximum, Sum, and SampleCount. NOTE: The number of samples equals to the count of data points.
Statistical Cycle	Interval at which metric data is collected. The statistical cycles that are available for you to select vary according to the time range.
Time Range	Time range in which metric data is collected. Options: Last 30 minutes, Last 1 hour, Last 6 hours, Last 1 day, Last 1 week, and Custom.
Refresh Frequency	Interval at which the metric data is refreshed. Options: Refresh manually, 30 seconds auto refresh, 1 minute auto refresh, and 5 minutes auto refresh.

Operation	Description
Adding a metric graph to a dashboard	Select a metric and click Add to Dashboard to add the metric graph to the dashboard.
Adding a threshold rule for a metric	After selecting a metric, click in the Operation column to create a threshold rule for it.
Exporting a monitoring report	Click Export Report to export a metric graph as a CSV file to your local PC.
Setting an interpolation mode	Click Interpolation Mode to set a mode for aggregating metric data. By default, AOM uses null to represent breakpoints in a metric graph. However, a metric graph with breakpoints is not suitable for reporting or presentation. To solve the problem, set Interpolation Mode to 0 or null to interpolate values. In this way, you can replace the missing metric data and avoid breakpoints. You can set Interpolation Mode to null, or 0. null: Breakpoints are represented by null by default. See the following figure. Figure 1 Graph when Interpolation Mode is null 0: Breakpoints are indicated by 0. See the following figure. Figure 2 Graph when Interpolation Mode is 0
Deleting a metric	Click in the row where the metric is located.
