[rrd-users] Re: rrdgraph using mysql

[Felipe Piccirilo]

Thanks Alex, but for sure, I *KNOW* it as musch as I know that i'm terrible in english. :)

What I was trying to ask is if this modifications, that I copied below, this is like create a rrd-database file in mysql.

Somewhere I can find more about using mysql as source database instead the cyclical rrd database?

For me, and in some applications, there's some cases that I could use mysql as source to calculate and display time-series data.

Maybe Mr. Greg tell something about it, can't you Mr. Greg?

Sorry about any mistakes in english.

best regards,

Felipe Piccirilo.
