Problem/Question
Hello everyone,
I am trying to export metrics from a Netdata agent to a Gnocchi server. To achieve this, I have created an exporting.conf file, the contents are as follows:
[prometheus_remote_write:gnocchi_instance]
enabled = yes
destination = x.y.z.w:8041
remote write URL path = /v1/prometheus/write
data source = average
prefix = netdata
hostname = myhost
username = admin
#password = admin
update every = 10
buffer on failures = 10
timeout ms = 20000
send names instead of ids = yes
send charts matching = *
send hosts matching = *
My Gnocchi server uses basic authentication, and it is not required to set a password when sending requests to the Gnocchi API. I did not observe any new metrics.
When I checked the Gnocchi logs, I saw the following entry:
[pid: 14|app: 0|req: 13877/27765] 10.204.189.1 () {32 vars in 430 bytes} [Thu Feb 29 13:46:10 2024] POST /v1/prometheus/write => generated 358 bytes in 166 msecs (HTTP/1.1 401) 3 headers in 109 bytes (2 switches on core 19)
T
This entry shows that the netdata agent is sending metrics, but something is preventing them from being received by Gnocchi.
I have attempted to comment and uncomment the “user” and “password” sections in the exporting file, but it did not make any difference.
Additionally, I have installed a Prometheus server and configured it to send its metrics to the Gnocchi server for testing. All the metrics were received correctly!
Here is my prometheus.yaml file:
global:
scrape_interval: 5s
remote_write:
- url: "http://gnocchi-api:8041/v1/prometheus/write"
basic_auth:
username: admin
password: admin
scrape_configs:
- job_name: prometheus
static_configs:
- targets: ['localhost:9090']
Can anyone help me troubleshoot this issue? Thank you.
