[Orca-users] intervals and RRDs

[Duncan Lawie]

From: Duncan Lawie <duncanl at demon.net>


Hi,

I have orca running for a set of systems.  orcallator is running on each

system with the default 300 second interval.  However, the data produced

is only rsynched to the web server every twenty minutes.  To avoid the
"file not current" message, I have set the interval in orcallator.cfg to

1200 i.e. 20 minutes.

I am now concerned about an earlier message concerning RRD and missing
data points.

Is this relevant to this case?

Am I better off setting the late_interval value to interval + 950?

Cheers,

Duncan.
