Issue with grafana query

Hi All,
when i using Http_response plugin in telegraf.conf as below

[[inputs.http_response]]
name_override = “url_monitor”
urls = [“AV Rental & Production Equipment - PRG Gear” , “http://rel.com/” , “http://ver.com”]

and in grafana dashboard i’m using the influxdb query as below

SELECT last(“http_response_code”) FROM “http_response” WHERE $timeFilter GROUP BY time($__interval), “server” fill(null)

its showing the servers which are not in the list of plugin which i have mentioned .where i have done the mistake .
