p404 opened a new issue, #10584:
URL: https://github.com/apache/apisix/issues/10584
### Current Behavior
When setting up the DataDog plugin globally with this configuration:
``` code json
{
"_meta": {
"disable": false
},
"constant_tags": [
"source:apisix",
"service:custom"
],
"host": "10.26.0.21",
"namespace": "ingress-apisix",
"port": 8125
}
```
The plugin still attempts to send data to 127.0.0.1, as indicated by this
error message:
```log
apisix-66f8859c6b-mnsdc apisix 2023-12-01T17:40:43.927546706-07:00
2023/12/02 00:40:43 [error] 50#50: *732097 [lua] datadog.lua:172:
send_metric_over_udp(): failed to report req body size to dogstatsd server:
host[127.0.0.1] port[8125] err: connection refused, context: ngx.timer, client:
10.24.0.5, server: 0.0.0.0:9443
```
Despite the specified host being "10.26.0.21", the plugin incorrectly
targets "127.0.0.1".
### Expected Behavior
Despite being configured to target the host "10.26.0.21", the DataDog plugin
incorrectly attempts to send data to "127.0.0.1"
### Error Logs
```log
apisix-66f8859c6b-mnsdc apisix 2023-12-01T17:40:43.927546706-07:00
2023/12/02 00:40:43 [error] 50#50: *732097 [lua] datadog.lua:172:
send_metric_over_udp(): failed to report req body size to dogstatsd server:
host[127.0.0.1] port[8125] err: connection refused, context: ngx.timer, client:
10.24.0.5, server: 0.0.0.0:9443
```
### Steps to Reproduce
1. Configure the DataDog Plugin globally.
2. Send a request to a route.
3. Inspect error logs to check whether ApiSix is trying to connect to
127.0.0.1 for sending metrics to DataDog.
