Dear Ladies and Gentlemen, Please would you help me eliminate aberrant data from my RRDs ?
The data results in spikes in the graphs and is . always occurring at the same time each day (when the collector - ntop - was restarted. Dev versions of the collector [ntop < 2.2] were much less stable; restarting reduced the likelihood of failures) . characterised by large numbers - clipped by rrdcgi so I don't know exactly what the values are - that are however, the same vaue in the graph as genuine maxima. . stored in the RRD as COUNTER (byte counts of protocols etc) What I think I would like to do is replace all instances of the values at the restart time (23:59) with UNKNOWNs _or_ have the graph ignore those values while processing large values that occur at other times. I am going to follow Alex's suggestions about temporarily putting in a MAX value before restoring the previously saved contents but I wonder are there any other ways. Is simply editing the XML a possibility ? Yours sincerely. -- ------------------------------------------------------------------------ Stanley Hopcroft ------------------------------------------------------------------------ '...No man is an island, entire of itself; every man is a piece of the continent, a part of the main.
