Metric descriptions
The main monitoring metrics are described in the following table:
Metric name | Description |
Call cache service - cal | Monitors metrics for application access to the cache. The configuration requirements are as follows: - The SOFA framework has no default log. - In a custom configuration, you can use your own log file. The log file must contain the data source, result, time consumed, and count. |
Call DB service - dal | Monitors metrics for application access to the database. The configuration requirements are as follows: - The SOFA framework uses |
Error - error | Monitors the number of error logs in the application and tracks error change trends. In Application Monitoring, you can click an error to view its related logs. The configuration requirements are as follows: - The SOFA framework uses the |
System monitoring - system | Monitors the resources of the virtual machine or ECS instance on which the application is running. This includes metrics such as CPU, Load, and Memory. The configuration requirements are as follows: - No log configuration is required. - You only need to enable this monitoring option. The monitoring agent automatically collects the data. |
PV - pv | Monitors the number of times pages in the application are called. The configuration requirements are as follows: - The SOFA framework uses |
Call external service - sal | Monitors metrics for calls made by the application to other services. The configuration requirements are as follows: - The SOFA framework uses |
Application service called - service | Monitors incoming calls to services within the application. The configuration requirements are as follows: - The SOFA framework uses |
SQL time consumed detection - sql | Monitors the execution status of SQL queries when the application accesses the database. This includes detecting slow SQL queries. The configuration requirements are as follows: - The default log file for the SOFA framework is `/home/admin/logs/tracelog/zdal-db-digest.log`. - In a custom configuration, you can use your own log file. The log file must contain the database, SQL statement, time consumed, and transaction ID. |
