I was able to set up riemann with SMTP. Riemann appears to send the email out when the condition is met but I observe an exception (copied below) - any insight on how to troubleshoot/fix this will be appreciated.
Config
(def email (mailer {:host "xxx.xxx.xxx.xxx"
:port "xxxx"
:user "user@somewhere.com"
:pass "user12345"
:from "user@somewhere.com"}))
(streams
(where (and (service #"^riemann netty execution-handler"))
(email "user@somewhere.com")))
Error:
#riemann.codec.Event{:host "ubuntu-3", :service "riemann netty execution-handler threads active", :state "ok", :description nil, :metric 0, :tags nil, :time 348380111059/250, :ttl 20000}
