Thank You Dainel. I trying to create an alert for more than 90 days of records for my audit purpose.
I only see the "last" xx days in the option, but I need more than > 90 days old data. Could you please help me with how to set it up? I tried in-dev tools and got the expected result.

GET kafka-xxxx-xxxx.*/_search
{
"_source": ["data.xxxxxx.xxxx.xxxx","@timestamp"],
"query": {
"range": {
"@timestamp": {
"gte": "now-90d"
}
}
}
}

But unable to achieve in alerting part.
