[collectd] Apache plugin error messages

[antonio.exposito at ono.com]

Hi all,

I have configurated properly the Apache plugin, and it worked quite 
well during months until I started to get this messages in the 
collectd.
log:

[2010-12-21 18:41:33] plugin_dispatch_values: Dataset not found: 
apache_idle_workers
[2010-12-21 18:41:33] plugin_dispatch_values: Dataset not found: 
fork_rate

I have collectd 4.10.1 and Apache/2.2.14 (Ubuntu).

any body knows what's the problem?

Thank you in advance,

Antonio
