查询janusgraph时遇到问题
我查询了50个相同的请求，结果是：
请求计数50（OK = 11 KO = 39）
最小响应时间5391（OK = 5391 KO = 5697） 最大响应时间5902（OK = 5902 KO = 5883） 平均响应时间5740（OK = 5642 KO = 5768） 标准偏差98（OK = 158 KO = 42） 响应时间50％百分位数5760（OK = 5580 KO = 5761） 响应时间75th百分位数5801（OK = 5773 KO = 5801） 响应时间95th百分位数5835（OK = 5870 KO = 5828） 响应时间99％百分数5893（OK = 5896 KO = 5864） 平均请求/秒5.556（OK = 1.222 KO = 4.333） ----响应时间分布------------------------------------------- ----- t <800毫秒0（0％） 800毫秒
1200毫秒11（22％） 失败39（78％） ----错误--------------------------------------------- ----------------------- > status.find.is（200），但实际上找到了500 39（100.0％）
我使用加特林和dropwizard测试janusGrpah。
我在dropwizard中看到此错误
