Error: text format parsing error in line 1: invalid metric name

[sushan...@gmail.com]

My configuration:

global:
  scrape_interval:     15s
  evaluation_interval: 15s
  external_labels:
      monitor: "gatewaymonitor"

scrape_configs:
  - job_name: "gateway"
    metrics_path: "/public/metrics"

    static_configs:
      - targets: ["10.8.110.83:18888"]

I'm using spring cloud zuul/hystrix/ribbon all the netflix oss.
I'm able to see the hystrix metrics here>> http://10.8.110.83:18888/public/metrics

I'm not able to see any issue with my prometheus.yml.
The error I'm getting: https://ibb.co/hDXR5w
Please help.

Enable verbose logging and check the name of the problematic metric. 

Prometheus metrics and label names must adhere to certain rules outlined here in the documentation, namely the metric name must match the regex [a-zA-Z_:][a-zA-Z0-9_:]*.

Hope that helps,

Conor

The error is not in your Prometheus.yaml, it's in the data (metrics) coming from your target at 10.8.110.83:18888/public/metrics

Try curling that address and see what it gives you.

This is data I received after hitting /metrics >> http://jsoneditoronline.org/?id=26dbc05242d6f12bba63df3f31ece107

is this the correct prometheus metrics data ?

[Nicholas Capo]

That data is json, not the Prometheus text format [0].
I have a feeling you are not using a Prometheus client library [1].

I'm was hitting incorrect endpoint , now after hitting http://10.8.110.83:18888/public/hystrix.stream I'm getting correct hystrix data but the formatting is still an issue. Data that I'm getting >>(http://jsoneditoronline.org/?id=2f71c34ed76155ddb92d94743793cbac)

And the error is >> " text format parsing error in line 1: invalid label name for metric "data:" "

Currently I'm only using this library >>

<dependency>
    <groupId>de.ahus1.prometheus.hystrix</groupId>
    <artifactId>prometheus-hystrix</artifactId>
    <version>3.3.1</version>
</dependency>

[sushan...@gmail.com]

Today I integrated spring_boot_client and changed the endpoint to /prometheus so now after hitting http://localhost:18888/public/prometheus I'm getting this data >> http://jsoneditoronline.org/?id=5d1a431c7cd9c72fa07d16eb075f4267 but after adding this into prometheus getting this error >> text format parsing error in line 109: second HELP line for metric name "counter_servo_eurekaclient_transport_request".

can you please help ?

[Nicholas Capo]

That error means you have an extra help line for that metric.
You are only allowed one `HELP` line above the first occurrence of a metric.

Allowed:
# HELP metric_name
metric_name{label="exampleA"} 1
metric_name{label="exampleB"} 1
[...]

Not Allowed:
# HELP metric_name
metric_name{label="exampleA"} 1
# HELP metric_name
metric_name{label="exampleB"} 1
[...]

I'll explain in detail what I've done: 
I've this code >> http://jsoneditoronline.org/?id=44919d5633d2613e0931753e35e51af5 
which is exposing spring boot metrics(I guess) to prometheus endpoint. 
Then before actually starting the spring application I add this line >> 
HystrixPrometheusMetricsPublisher.register("Gateway"); 
For these to work I've prometheus-hystrix library added + simpleclient_spring_boot library 

Now I can see some data without any error on /prometheus endpoint but I'm not sure whether this is actually hystrix data. here>> http://jsoneditoronline.org/?id=44919d5633d2613e0931753e35e62e7e 

When I point my prometheus.yml file >> 

global: 
  scrape_interval:     15s 
  evaluation_interval: 15s 

scrape_configs: 
  - job_name: 'gateway' 
    scrape_interval: 90s 
    scrape_timeout: 90s 
    metrics_path: '/prometheus' 
    static_configs: 
      - targets: ['localhost:18888'] 

like above then I get status as UP but in graph section it says no data points found.
