linux - nagios 中的监控 gearman

Question

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

本地主机是 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:

CRITICAL: gearman: gearman_client_run_tasks : gearman_wait(GEARMAN_TIMEOUT) timeout reached, 1 servers were poll(), no servers were available, pipe:false -> libgearman/universal.cc:331: pid(613)

有人可以帮我解决这个问题吗？

下面是脚本

#!/bin/sh
#
# gearman check for nagios

如果您下载 mod_gearman 软件包，其中包含一个更好且功能更丰富的 Nagios 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 是否正在本地主机上监听，并且没有本地防火墙阻止连接。您可能已将 gearmand 安装在不同的端口上，或者仅在网络接口(interface)上监听，而不是在本地主机上监听。或者它根本没有运行，或者与运行检查的服务器位于不同的服务器上......
