APM is the abbreviation of Application Performance Monitoring. Currently its core function is the performance diagnosis of distributed system, including call chain demonstration, application topology analysis, etc.

Sharding-Sphere Team work with SkyWalking Team to introduce an automatic monitor agent of Sharding-Sphere to send tracing data of Sharding-Sphere to SkyWalking.


Using SkyWalking

Please refer to SkyWalking Manual

Using OpenTracing

If user want to use other APM systems which support OpenTracing, just use sharding-sphere API to work with those APM systems.

Notices: When using SkyWalking’s OpenTracing monitor agent, disabling the original Sharding-Sphere monitor agent plugin is necessary to avoid conflicting with each other.
