FlashPool harvest graphs issue

[LORENZO_CONTI]

Hello,

I have noticed that for clusters monitored via harvest 1.4.2 flash pool graphs are showing no data.
The issue is not present where the poller is 1.3.

Is it possible something was wrong when we updated harvest?

Thank you

Hello,
the problem seems related to a template I added to start monitor a wafl parameter, here's the conf file

%poller = (
'wafl' =>
{
counter_list => [ qw(node_name node_uuid
inode_cnt
) ],
graphite_leaf => 'node.{node_name}.wafl',
enabled => '1'
},
);

Graph restarted to work when I removed the entry in harvest.conf.  What I'm doing wrong with templating?

Thank you
