> Issue Type: Improvement
> Security Level: Public(Default Security Level. Issues are Public)
> Components: AutoScaling
> Reporter: Varun Thacker
> Priority: Major
>
> As soon as I create a search rate trigger I see that the metrics endpoint is being queried every 1 second . As discussed on SOLR-12463 we should change the default to be 10 seconds
> Example trigger
> {code:java}
> curl -X POST -H 'Content-type:application/json' --data-binary '{
> "set-trigger": {
> "name" : "search_rate_trigger",
> "event" : "searchRate",
> "collection" : "test_rate_trigger",
> "rate" : 1.0,
> "waitFor" : "1m",
> "enabled" : true,
> "actions" : [
> {
> "name" : "compute_plan",
> "class": "solr.ComputePlanAction"
> },
> {
> "name" : "execute_plan",
