Nagios的报警信息CHECK_NRPE: Socket timeout after 10 seconds

Question

Nagios不稳定，检测的服务都是好的，但是有时会发警报信息。看了下详细日志，如下所示：

[03-19-2012 17:37:40] SERVICE NOTIFICATION: nagiosadmin;realhost2;Uptime;CRITICAL;notify-service-by-email;CRITICAL - Socket timeout after 10 seconds
[03-19-2012 17:37:40] SERVICE ALERT: realhost2;Uptime;CRITICAL;HARD;3;CRITICAL - Socket timeout after 10 seconds
[03-19-2012 17:36:40] SERVICE NOTIFICATION: nagiosadmin;realhost2;NSClient++ Version;CRITICAL;notify-service-by-email;CRITICAL - Socket timeout after 10 seconds
[03-19-2012 17:36:40] SERVICE ALERT: realhost2;NSClient++ Version;CRITICAL;HARD;3;CRITICAL - Socket timeout after 10 seconds

[03-19-2012 17:34:40] SERVICE ALERT: realhost2;NSClient++ Version;CRITICAL;SOFT;2;CRITICAL - Socket timeout after 10 seconds
[03-19-2012 17:33:40] SERVICE ALERT: realhost2;Uptime;CRITICAL;SOFT;1;CRITICAL - Socket timeout after 10 seconds
[03-19-2012 17:33:40] SERVICE ALERT: realhost2;Memory Usage;CRITICAL;SOFT;2;CRITICAL - Socket timeout after 10 seconds
[03-19-2012 17:32:40] SERVICE ALERT: realhost2;NSClient++ Version;CRITICAL;SOFT;1;CRITICAL - Socket timeout after 10 seconds
[03-19-2012 17:31:40] SERVICE ALERT: realhost2;Memory Usage;CRITICAL;SOFT;1;CRITICAL - Socket timeout after 10 seconds

以上信息说明都是“Socket timeout after 10 seconds”这个原因造成的，如何解决呢？

Answer 1

nrpe进程执行某些脚本可能是大于10秒钟，而默认的是10秒钟，所以会发报警信息。

解决的方法如下：

define command{
command_name check_nrpe
command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$ -t 30   # 加上一个 -t 30 指定时间为 30 秒
}
