我正在尝试通过nagios监视gearman，因为我正在使用脚本check_gearman.sh。

Localhost是Gearman服务器运行的地方。

当我运行时

./check_gearman.sh -H localhost -p 4730 -t 1000

结果是:



有人可以帮我这个忙吗？

下面是脚本

#!/bin/sh

# gearman check for nagios

最佳答案

如果您下载mod_gearman软件包，则该软件包包含Nagios更好，功能更强大的check_gearman插件。

使用您当前的插件，错误消息显示检查脚本无法连接到gearman守护程序。

您应该验证端口4370在本地主机上侦听，并且没有本地防火墙阻止连接。您可能已将Gearmand安装在其他端口上，或仅在网络接口(interface)上侦听，而不是在本地主机上侦听。也许它根本没有运行，或者与运行检查的服务器不在同一台服务器上...
