I have two rrd files. One which was being updated to a certain point then stopped (by choice). The second starting being updated a short time later (by choice).
These represent a connection that was moved from one interface to another. The problem is I can generate graphs on the data for the entire month for data sources in either file. I can also generate graphs with different defs for each datasource in the two files into one graph. However which I attempt to generate a combined datasource (CDEF) with the two over the period which the first file wasn't updated I get no graph. I'm pretty sure at this point it's because the first file has not been updated past a certain date. e.g. Both files contain 1 month of 5 minute samples. File 1 updated until March 19th 23:55. File 2 starting updating on March 20th 00:35. Here's a snatch of the RRD scripting DEF:out1=/usr/local/bubba/data/mn/routers/cisco/c7206-1/interfaces/serial2_0/200303.rrd:out:LAST \ DEF:out0=/usr/local/bubba/data/mn/routers/cisco/c7206-1/interfaces/serial1_0/200303.rrd:out:LAST \ CDEF:out1_bits=out1,8,* \ CDEF:out0_bits=out0,8,* \ CDEF:out_bits=out0,out1,+,8,* \ out0_bits & out1_bits would generate a graph, but out_bits would not. Any suggestions. Only thing I can think of is to go back and update the first file to the end of the month with NaN or 0. BTW in looking through the archives I noticed mentions of 95th percentile calcs. That's one of the things my package was designed for. -- Todd A.
