Lesson 3 gem not found

[tmonk42]

Working through the tutorial here: https://github.com/sensu/sandbox/tree/master/sensu-go/core

[sensu_go_sandbox]$ sensuctl version sensuctl version 5.0.1#af7d1d0, build af7d1d041092c130653cc8e2ca4b8aef479cb05a, built '2018-12-11T21:25:30+0000'

On Lesson 3, step 2 when I run the command by hand, it appears to work correctly: [sensu_go_sandbox]$ /opt/sensu-plugins-ruby/embedded/bin/metrics-curl.rb -u "http://localhost" sensu-go-sandbox.curl_timings.time_total 0.005 1545160704 sensu-go-sandbox.curl_timings.time_namelookup 0.004 1545160704 sensu-go-sandbox.curl_timings.time_connect 0.004 1545160704 sensu-go-sandbox.curl_timings.time_pretransfer 0.004 1545160704 sensu-go-sandbox.curl_timings.time_redirect 0.000 1545160704 sensu-go-sandbox.curl_timings.time_starttransfer 0.005 1545160704 sensu-go-sandbox.curl_timings.http_code 200 1545160704

Lesson 3, step 3 however is showing a gem error:

I was able to reproduce this issue as well:

"/opt/sensu-plugins-ruby/embedded/lib/ruby/site_ruby/2.4.0/rubygems.rb:270:in `find_spec_for_exe': can't find gem sensu-plugins-http (>= 0.a) (Gem::GemNotFoundException)\n\tfrom /opt/sensu-plugins-ruby/embedded/lib/ruby/site_ruby/2.4.0/rubygems.rb:298:in `activate_bin_path'\n\tfrom /opt/sensu-plugins-ruby/embedded/bin/metrics-curl.rb:22:in `<main>'\n",

Running the command as the Sensu user works too:

sudo -u sensu /opt/sensu-plugins-ruby/embedded/bin/metrics-curl.rb
sensu-go-sandbox.curl_timings.time_total 0.001 1545162358

thanks for the report.

Can you provide me the version of sensu-agent that is installed in the sandbox rpm -qa |grep sensu

[jspaleta]

I just commited a change that should help.

Can you retest against latest master branch and confirm that its working?

[tmonk42]

[sensu_go_sandbox]$ rpm -qa | grep sensu sensu-go-backend-5.0.1-1.x86_64 sensu-plugins-ruby-0.2.0-1.el7.x86_64 sensu-go-cli-5.0.1-1.x86_64 sensu-go-agent-5.0.1-1.x86_64

[tmonk42]

Updated against master, works now!
