APM¶
APM supports collectors using the Opentracing protocol to perform end-to-end link analysis of applications in distributed architectures. It also correlates with infrastructure, logs, RUM, quickly locates and solves faults, and improves user experience.
The best deployment plan is to deploy DataKit on each application server and hit the data to Guance through the DataKit of the server where the service is located. This can better gather metrics of application server hosts, application logs, system logs, application service link data, etc., and perform correlation analysis of various data.
Use Cases¶
Features¶
- Services: View service list, performance metrics and service call relationship map
- Overview: View the online services, P90 response time, maximum time-consuming service and other indicators
- Traces: Query and analyze all trace data reported based on tools such as flame graphs, etc.
- Error Tracking: View the historical trend and distribution of similar errors in the traces, quickly locating errors
- Profiling: View the application operation metrics, show the call relationship and efficiency in real time.
- APM Metric Detection: Discover abnormal link data in time by configuring application performance monitors
Data Storage and Billing¶
Guance provides three data storage durations for APM data: 3 days, 7 days, and 14 days. You can adjust in Management > Settings > Change Data Storage Strategy according to your needs.
For more data storage strategies, see Data Storage Strategy.
Based on the pay-as-you-go billing method, APM charges statistics the number of trace_id under the current space, and adopts the gradient pricing model.
