[jira] [Created] (SOLR-12463) Search rate trigger should check
metrics less often
Varun Thacker created SOLR-12463:
------------------------------------
Summary: Search rate trigger should check metrics less often
Key: SOLR-12463
URL: https://issues.apache.org/jira/browse/SOLR-12463
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Components: AutoScaling
Reporter: Varun Thacker
I created a search rate trigger by running this command
{code:java}
curl -X POST -H 'Content-type:application/json' --data-binary '{
"set-trigger": {
"name" : "search_rate_trigger",
"event" : "searchRate",
"collection" : "gettingstarted",
"rate" : 1.0,
"waitFor" : "1m",
"enabled" : true,
"actions" : [
{
"name" : "compute_plan",
"class": "solr.ComputePlanAction"
},
{
"name" : "execute_plan",
"class": "solr.ExecutePlanAction"
}
]
}
}' http://localhost:8983/solr/admin/autoscaling
{code}
As soon as I add this by logs start getting spammed with these every 1 second
{code:java}

....{code}
Does 1 second seem to aggressive ?
Maybe the waitFor could be taken into account and query the metrics at waitFor/2 or something ?
