First Look at RoseNMS screens

More work has gone into the various GUI screens for RoseNMS. While still early days, these screenshots give an idea of the final program.

Host Map

The maps have been updated and now just use CSS for layout, rather than hard calculating the coordinates using javascript. This gives a cleaner and more fluid look to the maps. Hovering over the map item will show more details about the item. There are maps for hosts (shown) as well as attributes.

Attribute View with information, graph and events
Attribute View with information, graph and events

Attribute details show some information about the attribute, the default graph and the events. Clicking on the more button above the graph takes you to the graph page for that attribute.

Graphs

Finally the graph handling is completely re-written with the concept of graph templates. These are basic types of graphs. The one shown is the basic “lines” template that shows… lines! Only things required are the RRD data source, the multiplier, the legend and how you want the units shown. From that the program builds all the required VDEFs and CDEFs.

What I learnt from LCA 2013

Well I’m back from LCA 2013 and what a great week it was. I learnt plenty of things over the week, including:

  • Cloud computing into the government will be coming but will be hard to do in a significant way
  • It wasn’t just me that found the GTK 2 to 3 API change hard going
  • OpenStack is the next cool kid on the block and there is a lot going on here
  • Try out novaprova for testing C programs
  • SELinux shouldnt slow my computer down and yes ill try it soon
  • git-annex looks very interesting, I’m just trying to find a use-case for it for me
  • The development methods for Free Software have come a long way since a decade ago
  • Test and release processes are important on large software projects
  • Pretty much everyone I knew has changed companies, at least once.
  • For multi-process communication, 0mq looks interesting

It was great to actually meet people who I’ve known for years (over 10 for some) only as emails or irc chats as well. I’ve not been to Mount Stromlo for almost as long and its somewhere I’d like to visit again.

Argh, the wordpress editor is still not fixed 🙁
