[mapguide-internals] Server status/Ping API

[Bruce Dechant]

A ping is supposed to be fast - adding overhead to generate a map image could be slow, but having this optional would get around that. What about security risks of being able to render a map without credentials? Obviously if it is a tiny thumbnail of the map it is not very useful at all - other than to see if the server is there and can render it.

Thanks,
Bruce

No problem on the performance metrics.

Martin's suggestion of doing a lightweight render is a good idea.  Perhaps we can make this an optional item with the render only occurring if a map definition resource id is supplied as an input parameter.  We could just render a small image at the map extents.  The various pieces - API version, offline/online, and image could be returned as an xml document with the image returned as a base64 blob.  Something like this perhaps:

<Ping>
  <Status>Online</Status>
  <ApiVersion>2.2</ApiVersion>
  <ImageSize>8061</ImageSize>
  <Image>[8061 base64 encoded bytes]</Image>
</Ping>

Thanks,
Trevor

The API version would be nice to have.

I have to agree that performance metrics without credentials I'm not sure I like.

I think it would be cool to return API version (2.1, 2.2, etc) as part
of this, but not rev/build.

Would be hesitant to return performance metrics through a non-authenticated api.
