Stack Samples Count by Thread State (Default report)\n2. Average CPU Usage of Threads (using both thread dump and `ps` output)\n\nThe first report also supports detecting Java level deadlocks.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fwso2%2Fperformance-troubleshooting-tools","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fwso2%2Fperformance-troubleshooting-tools","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fwso2%2Fperformance-troubleshooting-tools/lists"}
