title: How can I enable the DevArt performance counters in Resource Monitor?
body: <p>I'm using the <a href="https://www.devart.com/dotconnect/oracle/docs/PerformanceCounters.html" rel="nofollow noreferrer">DevArt dotConnect for Oracle performance counters</a> in my dev/test environment. By adding <code>Use Performance Monitor=True</code> to my database connection string, I can capture useful information such as number of connections, etc.</p>

  <p>However, on my production box, I cannot see the DevArt performance counters in Resource Monitor:</p>

  <p>I believe that the performance counters are installed, since they appear in the registry:</p>

  <p>...and I imagine that adding <code>Use Performance Monitor=True</code> to my database connection string would cause an error if the relevant DLLs etc. were not present.</p>
  <p>What else do I need to do to make the performance counters appear in Resource Monitor?</p>
