Summary overview dashboard - host pre-filter ineffective

[Guilhem Marchand]

There is an error in the Summary overview dashboard where the host pre-filter form is not actively filtering the list of available hosts.

Line 43:

                <query>search frameID=$frameID$ | stats count by host | dedup host | sort 0 host</query>

Should be:

                <query>search frameID=$frameID$ host=$host-prefilter$| stats count by host | dedup host | sort 0 host</query>
