logging - 为什么我的MongoDB日志中充满了 "getmore local.oplog.rs"？

这在我的MongoDB日志中一遍又一遍地重复。一些注意事项:

Ubuntu 11.04上的MongoDB 1.8.1

主副本集

64GB磁盘

5GB RAM

new Date(5610408224193773570)始终是相同的

verbose = true在配置文件

中被注释掉

可能是我的oplog太大了，所以每次辅助查询都需要4秒钟吗？

最佳答案

假设日期相同，则看起来辅助服务器正在查询新的oplog条目，却什么也没得到。您是否正在将任何数据写入主数据库？

该行为看起来有点不寻常。但是，我只是通过启动一个副本集而不是对其进行写操作就得到了相同的结果。您所看到的行为是预期的。
