Sensu 报告 'require'： 无法加载此类文件 -- net/ping

Question

我已经在3台机器上安装了sudo gem install net-ping，相同的设置。但是有一个服务器拒绝接受net-ping的安装。我错过了什么?

我正在尝试配置使用check-ping.rb的传感器

以下是sensu报告的内容

Answer 1

你可以使用"gem environment"来查找你的gem的安装路径:

# /opt/sensu/embedded/bin/gem environment
RubyGems Environment:
  - RUBYGEMS VERSION: 2.0.14
  - RUBY VERSION: 2.0.0 (2015-04-13 patchlevel 645) [x86_64-linux]
  - INSTALLATION DIRECTORY: /opt/sensu/embedded/lib/ruby/gems/2.0.0
  - RUBY EXECUTABLE: /opt/sensu/embedded/bin/ruby
  - EXECUTABLE DIRECTORY: /opt/sensu/embedded/bin

在本例中是/opt/sensu/embedded/lib/ruby/gems/2.0.0。然后你可以在那里搜索，如果你有"net-ping"，并验证权限。

# ls -1 /opt/sensu/embedded/lib/ruby/gems/2.0.0/gems/ | head -3
amqp-1.5.0
amq-protocol-1.9.2
amq-protocol-2.0.1

别忘了使用"/opt/sensu/embedded/bin/"里面的二进制文件
