这是我的mtail配置

progs = "/usr/local/n9e/categraf/current/conf/input.mtail/mtails.rules"

emit_metric_timestamp = "true"
gauge netcard_down_count by netcard
#网卡监控
/\w{3}\s\d{2}\s\d{2}:\d{2}:\d{2} \S+ \S+ \S+ \S+ \S+ \S+ (?P<netcard>\S+) NIC Link is (Up|Down)/ {

}
目前告警正常，cpu，内存什么的看起来也暂无影响，但想问问这个日志是为什么？是什么过期了？
