版本：6.7.3
categraf 指向 edge后，指标等数据可以正常采集，但在页面的机器列表中无对应主机，同时edge中出现报错：ERROR idents/idents.go:82 failed to update targets: unexpected status code: 401。
categraf 配置如下：
[[writers]]
url = "http://127.0.0.1:19000/prometheus/v1/write"
# Basic auth username
basic_auth_user = ""
# Basic auth password
basic_auth_pass = ""
......
[heartbeat]
enable = true
# report os version cpu.util mem.util metadata
url = "http://127.0.0.1:19000/v1/n9e/edge/heartbeat"
# interval, unit: s
interval = 10
# Basic auth username
basic_auth_user = ""
# Basic auth password
basic_auth_pass = ""
