Hello all I have some existing rrdfile with some data in them. I was reading about the VDEF capabilities of the rrdgraph command. I am using the c library functions to manipulate the rrd files. I want the MAX and LAST from a graph, but I don't want the graph. At the command line I would do: rrdtool graph xy.png -aPNG DEF:curclientconns=/var/rrd/connections:curclientconns:AVERAGE VDEF:connsmax=curclientconns,MAXIMUM VDEF:connslast=curclientconns,LAST PRINT:connslast:"last=%12.0lf" PRINT:connsmax:"max=%12.0lf" This prints to stdout. If I am calling rrd_graph() C function, how do I get this data? Is there a better way to do this? I m very open to suggestions, but I have to stick with the C library calls. Ok, one more question: I dont see any API docs for theC library on the web site. Are there any? Thanks again
