[rrd-users] RRDTool as a server in Solaris

[Jose Ignacio Gil Jaldo]

Hi Steve,

I will try what you suggest but there is a couple of things that are strange
to me in what you say.

1. I completely agree with except for the fact that when I run in
commandline: rrdtool - <directory> the process does not end (it waits until
I type commands). That's why it's so strange to me that the process exists
inmediately.
2. I know that stop method is not right (as I recognized in my first post)
but as I am not very proficient in Solaris/SMF/RRDTOOL I was trying to solve
the problem incrementally. So first of all I wanted to start the process.

I will try 1 option and see how it goes.

Thanks
