title: EventLogQuery: How to form query string?
body: <p>I have the following code:</p>
  
  <pre><code>string query = "???";
  
  EventLogQuery elq = new EventLogQuery("Application", PathType.LogName, query);
  elq.Session = new EventLogSession("x.x.x.x");
  EventLogReader elr = new EventLogReader(elq);
  </code></pre>
  
  <p>I'm trying to figure out what I need to set query to in order to look for all entries with a source of "SQLSERVERAGENT".</p>
