Alert rules based on munin

I can’t figure out how to add alert rules based on munin graphs.
is it possible at all?

my munin script generates field - value output,:
load-kt.value 15553
load-2.value 14468
load-1.value 14841

and I suppose librenms should be saving this output somewhere in mariadb or not?

and if there is no data in database you cannot add alert, because you need entity.
So at this moment my graph are just nice to look? useless?

not sure?

actually there is no performance data in that table, I’m afraid there is no munin graph data in database at all.
