The value in this file is used when an application calls inotify_init(2) to set an upper limit on the number of events that can be queued to the corresponding inotify instance. Events in excess of this limit are dropped, but an IN_Q_OVERFLOW event is always generated. 可以监控事件的最...
/proc/sys/fs/inotify/max_queued_events 默认值: 16384 该文件中的值为调用 inotify_init 时分配给 inotify instance 中可排队的 event 的数目的最大值,超出这个值得事件被丢弃,但会触发 IN_Q_OVERFLOW 事件 /proc/sys/fs/inotify/max_user_instances 默认值: 128 指定了每一个 real user ID 可创建的 ino...
inotify 使⽤⽰例 使⽤场景 监听⽂件或者⽬录的变更，最终⽬的⼀定是基于不同的变更事件采取相对应的处理措施。⽐较常见的使⽤场景如下:配置⽂件热加载,当配置⽂件发⽣变化时进程可以⾃动感知并重新 reload 配置⽂件，如 golang 的明星项⽬-- 配置保持功能,当我们需要保持服务器上某些...

调用inotify_init时分配到inotify instance中可排队的event数的最大值,超出值时的事件被丢弃,但会触发队列溢出Q_OVERFLOW事件。 max_user_instances 每一个real user可创建的inotify instances数量的上限 max_user_watches 每个inotify实例相关联的watches的上限,即每个inotify实例可监控的最大目录、文件数量。如果监控的...

其中max_queued_events这个文件记录inotify事件队列最大长度,如值太小会报Event Queue Overflow 错误,默认值:16384,当然这个值是可以更改的,临时更改可以用echo 命令加上值给重定向到这个文件中。永久修改需要修改编辑/etc/sysctl.conf 1 2 3 4 5 6 7
max_queued_events:inotify 事件队列最大长度,如值太小会出现 Event Queue Overflow 错误,默认值:16384, 生产环境建议调大,比如:327679 max_user_instances:每个用户创建inotify实例最大值,默认值:128 max_user_watches:可以监视的文件的总数量(inotifywait 单进程),默认值:8192,建议调大 ...
