Hello, Problem 1 =========
This may seem absurd but I have a need to specify --start 0 or some small number with rrdtool create. That is, I want it to start timing from 0 or 1 seconds after 1970. However if I specify 0 or 1, the start time defaults to now. If I specify 100 say, I get an error message asking if I meant month 100 instead, but I don't. (If you really want to know why I need to do this, I've included it at the end) Problem 2 ========= I would like to control rrdtool from a C program. The way I am doing it now is using rrdtool's remote control feature. I fork a process to exec rrdtool, and make a pipe from the controlling program to the rrdtool program's stdin. Then I use fprintf with the pipe to issue commands. While this is working for small amounts of data, I get a pipe error signal if I input a lot of data too fast, which I need to do. Is there a more efficient way to control rrdtool from C? If not, does anyone know how I can avoid this error? Problem 3 ========= I'd like to display seconds since 1970 on my x-axis, but no strftime format will let me do it. Is there a way? Thanks and regards, Cheng Hu (Reason: I am running of network stack monitoring program that I wrote that generates data on microsecond resolution, and generates a lot of data. I'd like to graph this using rrdtool (is there a better tool for this purpose?) so I convert microseconds to second, and seconds times 1000000. To avoid overflow, I need to start from time 0) -- Unsubscribe mailto:[EMAIL PROTECTED] Help mailto:[EMAIL PROTECTED] Archive http://www.ee.ethz.ch/~slist/rrd-users WebAdmin http://www.ee.ethz.ch/~slist/lsg2.cgi
