Enterprise edition

Swoole EnterpriseAs aSwooleAn official set of enterprise-class productsPHPAndSwooleAnalysis and debugging tools can be used free of charge but not open source.

  • Grasp the application architecture model at all times: discover the topology structure and display of application dependencies automatically, and grasp the application architecture model at all times
  • Distributed cross-application link tracking: supports non-invasive distributed cross-application link tracking, making each request clear at a glance, fully supports coordinated/non-coordinated environments, and visualizes data in real time
  • Comprehensive analysis and reporting of service status: statistics of call information reported by services in various dimensions, such as total traffic, average time consumption, timeout rate, etc., and comprehensive analysis and reporting of service status
  • It has a powerful debugging tool chain: the system supports remote debugging, and can be turned on remotely to detect memory leakage, blocking detection and code performance analysis.
  • Perfect system monitoring: support perfect system monitoring, zero-cost deployment, monitoring of machinesCPU, memory, network, disk and other resources can be easily integrated into the existing alarm system.
  • Zero cost access system:Swoole EnterpriseSystem client script one-click deployment, the server can be inDockerRun in the environment, simple and fast

Version update

  • Debugger Function: ThroughSwooleEnterprise backstagePHPA button in the process list that dynamically turns on/off onePHPThe memory leak detection, performance analysis and blocking detection of the process can export the requested function call performance analysis diagram and flame diagram.
  • Application tracking function: to track applications (trace) and performance analysis data and congestion detection data, can jump to each other, convenient multidimensional positioning performance problems
  • Alarm function: add monitoring alarm for disk /cpu/ memory usage rate, and send WeChat/SMS alarm automatically when system resources exceed threshold value
