title: How to subscribe to "+odown", "+sdown", "+switch-master" in Redis command line?
body: <p>I want my redis-cli client to subscribe to sentinel notifications like &quot;+odown&quot;, &quot;+sdown&quot;, &quot;+switch-master&quot;, here is what i tried:</p>
  <pre><code>$ redis-cli
  127.0.0.1:6379&gt; subscribe &quot;+odown&quot;
  </code></pre>
  <p>nothing... I triggered a failover, still nothing.</p>
  <p>To make sure my connection is good, I tried <code>psubscribe *</code> and triggered another failover, I only see a bunch of:</p>
  <pre><code>3) &quot;__sentinel__:hello&quot;
  4) &quot;127.0.0.1,5001,ece169c208d80543b07a18ead87c53eb4bd87e4a,30,mymaster,127.0.0.1,6380,30&quot;
  1) &quot;pmessage&quot;
  2) &quot;*&quot;
  3) &quot;__sentinel__:hello&quot;
  4) &quot;127.0.0.1,5001,ece169c208d80543b07a18ead87c53eb4bd87e4a,30,mymaster,127.0.0.1,6380,30&quot;
  1) &quot;pmessage&quot;
  2) &quot;*&quot;
  3) &quot;__sentinel__:hello&quot;
  4) &quot;127.0.0.1,5000,060d95f0255ca3a70fa33b5caa5dbba787c3af55,30,mymaster,127.0.0.1,6380,30&quot;
  </code></pre>
