The Sensu assets packaged from this repository are built against the Sensu Ruby runtime environment. When using these assets as part of a Sensu Go resource (check, mutator or handler), make sure you include the corresponding Sensu Ruby runtime asset in the list of assets needed by the resource. The current ruby-runtime assets can be found here in the Bonsai Asset Index.
bin/check-ssl-anchor.rb
Check that a specific website is chained to a specific root certificate (Let's Encrypt for instance). Requires the openssl
commandline tool to be available on the system.
./bin/check-ssl-anchor.rb -u example.com -a "i:/O=Digital Signature Trust Co./CN=DST Root CA X3"
bin/check-ssl-crl.rb
Checks a CRL has not or is not expiring by inspecting it's next update value.
You can check against a CRL file on disk:
./bin/check-ssl-crl -c 300 -w 600 -u /path/to/crl
or an online CRL:
./bin/check-ssl-crl -c 300 -w 600 -u http://www.website.com/file.crl
Critical and Warning thresholds are specified in minutes.
bin/check-ssl-qualys.rb
Checks the ssllabs qualysis api for grade of your server, this check can be quite long so it should not be scheduled with a low interval and will probably need to adjust the check timeout
options per the check attributes spec based on my tests you should expect this to take around 3 minutes.
./bin/check-ssl-qualys.rb -d google.com
bin/check-ssl-root-issuer.rb
Check that a specific website is chained to a specific root certificate issuer. This is a pure Ruby implementation, does not require the openssl cmdline client tool to be installed.
./bin/check-ssl-root-issuer.rb -u example.com -a "CN=DST Root CA X3,O=Digital Signature Trust Co."
To run the testing suite, you'll need to have a working ruby
environment, gem
, and bundler
installed. We use rake
to run the rspec
tests automatically.
bundle install
bundle update
bundle exec rake
bin/check-ssl-anchor.rb
and bin/check-ssl-host.rb
would be good to run in combination with each other to test that the chain is anchored to a specific certificate and each certificate in the chain is correctly signed.
