here is a short description how this plugin works and how it can be installed/configured. I have also attached a screen shot which shows the current state of development.

This looks great.

One question: There are tags of the form

<value> 1.2596666368e+09 </value>

What are the T_* tags meant to mean? Is this a time stamp? In this case it would probably be better to make in an attribute of the value element and use the ISO format to make it more readable. The T_* tags are unix timestamps. It is possible to request a time

If there is data in the tag itself it makes parsing a bit harder. So I would suggest to just use a series of value tags with the datetime as attribute:

<value dateTime="2009-07-13T18:01Z">8.9377540389e+08</value> <value dateTime="2009-07-14T18:01Z">9.9377540389e+08</value>

Thank you for the suggestion.

This raises the general question if XML and REST are good encapsulations for such data. I very much doubt it.

The resource should be used to configure and manage the monitoring service. Transfering (possibly) huge amounts of data should be done by other means.

This shouldn't be a general problem. To reduce the amount of data, it can be compressed. It's possible to do this transparently. Or it could be transferred in an alternative format like JSON or something else which is more efficient. -- Cornelius Schumacher -- To unsubscribe, e-mail: yast-devel+unsubscribe@opensuse.org For additional commands, e-mail: yast-devel+help@opensuse.org
