@lucasponce What do you think about have the alerts of DataSource mw_ds_average_get_time, mw_ds_average_creation_time and mw_ds_max_wait_time like a Rate type instead threshold?

It might sense to use a rate or threshold, as behaviour are different in any case, I woud ask in the JIRA linnking the PM to confirm requeriment.

@lucasponce John told me in JIRA that we have to do with threshold. Can you review this PR? We need to request the merge in the UI ManageIQ/manageiq-ui-classic#2309

[aljesusg]

@miq-bot assign @abonas

@miq-bot add_label alerts, enhancement

[aljesusg]

@lucasponce ManageIQ/manageiq#16125 was merged, we need this to continue and for UI.

[lucasponce]

Minor PR, I see it correct, but I haven't tested locally.
