after installation ping_exporter i had two problems

1. dont see and find commnad ping_loss_ratio and like this in grafana
2. cant config new target in prometheus.yml
   this is my config

`` - job_name: 'ping'
metrics_path: /ping
static_configs:
- targets:
- google.com # Target to ping
relabel_configs:
- source_labels: [address]
target_label: __param_target
- source_labels: [__param_target]
target_label: instance
- target_label: address
replacement: 127.0.0.1:9427 # This exporter's real hostname:port

show this error : expected a valid start token, got "<" ("INVALID") while parsing: "<"
