Question

我正在尝试正确配置FreeBSD 10.1中安装的collectd（5.4.2）插件。我希望根据下面的配置来实现请参阅由rsyslog管理的/ var / log / messages文件中的警告事件它为在警告级别及以上级别报告的任何设施写入此文件。

我没有收到任何阈值警告。我使用过像＃34; stress -c＆＃34; 迫使闲置＆＃34; jiffies＆＃34;。

我似乎成功收集了基于使用rrdtool lastupdate显示的信息

/var/db/collectd/rrd/localhost/cpu-average/cpu-idle.rrd
/var/db/collectd/rrd/localhost/tail-messages/counter-os.rrd

我怀疑这是关于插件，类型和实例关键字的尾部，聚合，链或阈值的配置声明我不太正确。

我正在寻找各种设施的问题认为GaugeInc将是更合适的DSType，但事实并非如此我当前的收集版本支持。

欣赏有关设置问题的任何见解。

Answer 1

阈值最常见的错误是过滤限制过多。尝试删除func startApp(){ let difference = self.currentBackgroundDate.timeIntervalSinceDate(NSDate()) self.handler(difference) //update difference self.start() //start timer }，Host等部分，直到您看到通知为止。此外，您可以使用Instance插件来unixsock假值，而不是尝试刻录您的系统。

收集Theshold插件而不是警告rsyslog
