>
> Identify which Catalog and Statestore instance is active from the web debug
> endpoint.
> For the HA, we should improve the label on catalog and statestore web
> response to indicate "Active" instance.
> On the main page we could indicate "Status: Active" or "Status: Stand-by". We
> could probably add the status at the top of the main page before *"Version"*
> . The current details as output of a curl request on port 25020:
> {code:java}
> <h2>Vers<span id="v">i</span>on</h2>
> <pre id="version_pre">catalogd version 4.0.0.2024.0.18.0-61 RELEASE (build
> 82901f3f83fa4c25b318ebf825a1505d89209356)
> Built on Fri Mar 1 20:13:09 UTC 2024
> Build Flags: is_ndebug=true cmake_build_type=RELEASE
> library_link_type=STATIC </pre>
> <!-- The space after is necessary to add a space between each flag when

> Corresponding curl request on statestored on 25010:
> {code:java}
> <h2>Vers<span id="v">i</span>on</h2>
> <pre id="version_pre">statestored version 4.0.0.2024.0.18.0-61 RELEASE
> (build 82901f3f83fa4c25b318ebf825a1505d89209356)

> library_link_type=STATIC </pre>
> <!-- The space after is necessary to add a space between each flag when

> <h2>Process Start Time</h2>
> {code}
> Catalogd active status can be figured out using the catalogd metric:
> "catalog-server.active-status"
> Statestored active status we probably don't have a metric so should add a
> similar metric and use that to determine status.
