はじめに
意気揚々と sensu-client for Windows をセットアップしようとしたらハマったのでメモ。まだ、解決していませんのでご注意下さい。
以下のようなエラーが出て sensu-client が起動しません

原因や議論
まだ、解決されていないようです。そもそも、問題なのかも不明です。
取り急ぎの対処
sensu-em を修正する
ここでも書かれていますが、ここを下記のように修正することで回避は可能です。
EventMachine::set_tls_parms(@signature, priv_key || '', cert_chain || '', verify_peer, (use_tls ? true : false), cipher_list || '')
を
EventMachine::set_tls_parms(@signature, priv_key || '', cert_chain || '', false)
ちょっと現実的ではないようです。。。
0.12.6 を利用する
取り急ぎ
引続き、こちらに関しては追っかけていきます。
