What does this mean, what are we confirming? I missed this.&lt;BR /&gt;&lt;STRONG&gt;A: &lt;/STRONG&gt;The Virtual Proxy must have an Engine attached in order to process data. The setup for this is in the VP config of QMC&lt;BR /&gt;&lt;BR /&gt;&lt;STRONG&gt;Q: &lt;/STRONG&gt;Are there good strategies in troubleshooting outages or QS Engine slowness by looking in the Operations Monitor?&amp;nbsp;&lt;BR /&gt;&lt;STRONG&gt;A: &lt;/STRONG&gt;Yes, the Ops Monitor will show you trends over time and you can correlate that to system usage. Keep in mind that the Ops Monitor only pulls from Archived Logs&lt;BR /&gt;&lt;BR /&gt;&lt;STRONG&gt;Q: &lt;/STRONG&gt;Are 10000 users to much for QlikSense? Accessing the hub is quit slow.&lt;BR /&gt;&lt;STRONG&gt;A: &lt;/STRONG&gt;Largely depends on the size of your system, but that's on the high end of what I've seen in the field. Are all users active on the system? If not, I would use an LDAP filter to only include the ones you need. Or use the option to only sync the users that are active.&lt;/I&gt;&lt;BR /&gt;&lt;BR /&gt;&amp;nbsp;&lt;/P&gt;</description>
