Application Real-Time Monitoring Service:QueryMetricByPage

Obtain the PID of an application

In the left-side navigation pane of the ARMS console, choose Application Monitoring > Application List or Browser Monitoring > Browser Monitoring. On the Application List or Browser Monitoring page, click the name of the application that you want to view.

The URL in the address bar contains the process ID (PID) of the application. The PID is indicated in the pid=xxx format. The PID is usually percent encoded as xxx%40xxx. You must modify this value to remove the percent encoding. For example, if the PID in the URL is eb4zdose6v%409781be0f44d****, you must replace %40 with an at sign (@) to obtain eb4zdose6v@9781be0f44d****.

Application Monitoring metrics that can be queried

NoteYou must set the pid and regionId filter conditions by specifying the Filters parameter. You must set all known filter conditions by specifying the Filters parameter to define the range of query results. If no filter conditions are known, you can specify one or more dimensions provided in the following table to narrow down the query range.

Browser Monitoring FAQ

• Why does an error about the RAM permissions occur when I call the API? This is because the RAM user does not have required permissions. You can grant the permissions to the RAM user. For more information, see Use a RAM role to access resources across Alibaba Cloud accounts.

• How do I obtain a list of data entries without specifying a time interval? Set the intervalInSec parameter to 2147483647.

• Why is 0 returned for all the queries?

  • Check whether the time interval that you set is too short. Make sure that the value of the intervalInSec parameter is greater than or equal to 60,000.

  • Check whether the value of the regionId parameter is valid. The value depends on the region where the server that receives logs resides, rather than the region where you reside. You can identify the region ID based on the URL of the log source.

    • URL of the log source in the China (Hangzhou) region: https://arms-retcode.aliyuncs.com/r.png?
    • URL of the log source in the Singapore region: https://arms-retcode-sg.aliyuncs.com/r.png?
    • URL of the log source in the US (Silicon Valley) region: https://retcode-us-west-1.arms.aliyuncs.com/r.png?

• Why does an error occur when I call the simulator or an API?

  • Check whether the regionId parameter is specified and whether the pid parameter is specified by using the Filters parameter.
  • Check whether you have specified a valid value of the Measures or Dimensions parameter for the metric. For more information, see the Browser Monitoring metrics that can be queried section in this topic.

• Error messages and solutions

  • Query error. Contact the administrator.

    • Check whether the value of the Metric parameter is valid.
    • Check whether the value of the Measures or Dimensions parameter is valid.
    • Check whether the pid parameter is specified by using the Filters parameter.

  • InvalidIntervalInSec Check whether the value of the intervalInSec parameter exceeds the maximum value 2,147,483,647.

  • MissingMeasures Check whether the Measures parameter is specified.

  • NonsequenceParameter.Dimensions

    • Check whether the value of the Dimensions parameter is valid.
    • Check whether the value of the Dimensions parameter contains extra spaces.

  • ServiceUnavailable Check whether the value of the regionId parameter is valid.

  • Invalid Region Check whether the value of the regionId parameter is valid. The value depends on the region where the server that receives logs resides, rather than the region where you reside. You can identify the region ID based on the URL of the log source.

    • URL of the log source in the US (Silicon Valley) region: https://retcode-us-west-1.arms.aliyuncs.com/r.png?

• Why are some Measures or Dimensions parameters missing from my dataset? This happens because you can specify a maximum of five Measures or Dimensions parameters. If more than five parameters are specified, no data can be returned.

• Why does the sum of some metrics significantly decrease after they are aggregated compared with when they were not aggregated? For example, when the values of the pv parameter for the webstat.index metric are aggregated, the sum of aggregated values is significantly less than the sum of all the individual values. The API gateway admits a maximum of 10,000 data entries at a time. Additional data entries are discarded. When you attempt to aggregate more than 10,000 data entries, only the first 10,000 data entries are aggregated and the rest are discarded. This causes the aggregated result to be far less than the result of individually adding all the values. You must make sure that no more than 10,000 data entries are returned for each request. This ensures that you can obtain an accurate aggregated value.
