Input.http in xml to output Prometheus no data in /metrics from input

1

i wanted migrate to telegraf from msi afterburner exporter to prometheus.

msi afterburner remote server uses XML by http://x.x.x.x:82/mahm

so i have :

# Read formatted metrics from one or more HTTP endpoints
[[inputs.http]]
  ## One or more URLs from which to read formatted metrics.
  urls = ["http://192.168.0.101:82/mahm"]
data_format = "xml"

## Multiple parsing sections are allowed
  [[inputs.http.xpath]]
    ## Optional: XPath-query to select a subset of nodes from the XML document.
    metric_selection = "//HardwareMonitorEntry | //HardwareMonitorHeader | //HardwareMonitorGpuEntry"

    ## Optional: XPath-query to set the metric (measurement) name.
    metric_name = "string('afterburner')"
  
    ## Field specifications using a selector.
    field_selection = "child::*"
  
# Configuration for the Prometheus client to spawn
[[outputs.prometheus_client]]
  listen = ":9892"
  ## Only metrics whose measurement name matches a pattern in this list are emitted.
  namepass = ["afterburner*"]

telegraf --config --test --debug

/etc/telegraf $ telegraf --config /etc/telegraf/telegraf.conf --test --debug 2>&1 | grep -Fi afterburner

/etc/telegraf $

also i can get to http://192.168.0.199:9892/metrics but here no data from input

is i missed some step ?

i was able to make output but not what i need :
