  • Step or Sloping Graphs

    Even though the backend of Rosenberg NMS uses rrdtool RRD files, the front end graphs are created using jqPlot.  The idea is to have a set of templates for the different types of graphs and just apply them to the various data sets.  It makes things a lot simpler for new graphs because you just…

  • jqplot in Turbogears

      I’ve been working on the Rosenberg NMS graphs slowly migrating them from using rrdtool graph and using jqplot.  While there have been many false-starts and re-works, I now have a working set of graphs, two of which are shown on the page.

There should be a lot less warnings and errors from PHP when you set to a higher error level. Fixed error in syslog consolidator…
