Can you share the metric name that was problematic?

[talhakabakus]

That's all the configuration I have done @brian-brazil, when I enter Prometheus -> Status -> Targets, I see the error I shared in the previous post.

[brian-brazil]

You application is producing an invalid metric name. This is a bug in the application, can you indicate which client library you're using?

[talhakabakus]

I use Payara application server that hosts a Java EE web app.

[brian-brazil]

So you're using https://github.com/prometheus/client_java ?

Ok @brian-brazil, just figured out the reason of the error - something related with my security restrictions. Thanks for your guidance.

Hello Brian-brazil,

This is my prometheus configuration file.

my global config

global:
scrape_interval: 15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.

scrape_timeout is set to the global default (10s).

Attach these labels to any time series or alerts when communicating with

external systems (federation, remote storage, Alertmanager).

external_labels:
monitor: 'codelab-monitor'

Load rules once and periodically evaluate them according to the global 'evaluation_interval'.

rule_files:

• "first.rules"
• "second.rules"

A scrape configuration containing exactly one endpoint to scrape:

Here it's Prometheus itself.

scrape_configs:

The job name is added as a label job=<job_name> to any timeseries scraped from this config.

• job_name: 'prometheus'

  metrics_path defaults to '/metrics'

  scheme defaults to 'http'.

  static_configs:

  • targets:
    • "10.93.1.134:9100"
    • "10.9.64.47:9100"

Issue: In prometheus dashboard i can see the target servers are showing DOWN not sure what would be the issue. I might be doing something wrong. Any help would be greatly appreciated. Please find attached screeen shot is what i'm facing
