One writer, multiple readers

by Jack Tavares :: Rate this Message:

Hello all

In my setup I have one program writing to my rrd files

using rrdtool executable.

I have, until now, only had one program reading my rrd files

using rrdgraph.

We are, in the future going to also use CGI to run rrtdump

on the rrd files.

It is likely that the 2 processes will try to read the same

file at the same time (eventually)

Do I need to worry about multiple readers? Do I need

to implement some sort of reader lock external to the

rrd tool processes?

Thanks

jack
