<ul>
<li>Because we always want this to work we use the raw Gauges built in <tt>general-admin-system.xml</tt>. If we didn't then the deployer could filter out the results. Of course that might be what they want, but if they did why would then then be using this page and not the general admin page?</li>
<li>The current status code will report about every known sub-service (Metadata Resolver or Data Connector). The Gauges only record non null dates. so
<ul>
<li>We only report Data Connectors that have ever failed (saying "No Data Connector has ever failed" if none have). This means that static data connectors are never reported.</li>
<li>We only report Metadata Resolvers that have tried at least once to refresh (saying "No Metadata Resolver has ever attempted a reload" if none have)</li>
</ul> </li>
<li>The rest of the reporting is done from the services interface not via the gauges (even for attribute resolution and metadata resolution where we have the info in a gauge).</li>
<li>It would be possible to recode the whole thing using the deployer specified registry and gauges and nothing else, but would that bring any benefit over and above what we have ? Apart from being jsp code to duplicate the existing admin flow - Remember that the only motivation here is to stop us exposing an impl class in our jsp (which we have achieved).</li>
</ul> <p style="margin: 10px 0 0 0">I can be argued out of any of the above positions. If no counter arguments occur I'll close this in a week or so.</p> </td>
