Stef, is there a way to adjust the memory so it can't exceed 100%? Does it make sense for actual memory usage to be more than 100%? The graph.cfg definition for [mem], [memory] and [ram] have "-u100" defined, which means xymon will likely not graph data points greater than 100. Also, I suspect the code that creates the RRD file will have set the upper value to 100, and will cause xymon to drop data points greater than 100. No, Actual memory on AIX is the amount of memory in use. And this can be more then 100% of the physical memory. If it does, swap will be used as memory. This is of course if you use the physical memory as the max for actual memory. If you take swap + physical as the max for actual, It can never exceed 100%. But that's normally not done. You want to know if the memory that's needed can fit in the physical memory.
For linux, bbwin, freebsd and irix the actual memory is processed. And I don't see why this can't exceed 100% on theses OS'es if you allocate too much memory. But I never had a case, except for AIX.
And for the code that generated the rrd, that's also changed in my patch.
And for the graph, indeed, that definition also needs to be updated.
