prometheus

Hi,

first thanks for this awesome software. But I have some trouble and I don't know how to proceed. First I try to find out what else I could provide for this report to be a good bug report.

First, I use the latest version (v1.14.0) from openSUSE build Service. I know, I should compile it by my self to avoid any other causes for this behavior. But for now I still use this package from there

Steps to reproduce:

1. Try to tab through the home dashboard

Actual Result:

Question

• java agent support dubbo 3.0

Is your feature request related to a problem? Please describe.

my /var/log directory has files with different structures, which requires me to use different pipeline_stages for each set of different files.

Describe the solution you'd like

something like this would exclude all files that match the pattern /host/var/log/contained.*.log:

    static_configs:
      - 

This is a reminder for me or a task if anyone wants :P

Basically, The last two questions aren't really regex's questions.

To do:

• Move said questions to correct place.
• Add new regex questions (Python related!)?
• Maybe add a new ## Regex section, as it is a valuable skill

Currently those are only in our website. Let's at least add them to Readme as a link. (:

po-lint was useful when there was no tools like kubeconform (which we use in kube-prometheus project). And support for CRDs in kubernetes was at earlier stage. Right now po-lint seems like a largely unused code.

We would need to change docs at https://github.com/prometheus-operator/prometheus-operator/blob/master/Documentation/user-guides/linting.md

Current Behaviour

The flamegraph sorts the siblings in ascending order by frame's name.
The reference to code is here

Expected Behaviour

The siblings should appear in order of their start time.
This can be achieved according to library docs mentioned [here](https://github.com/spiermar/d3-fla

In this document, following sentence has a typo,

# Register the intrumentation handlers (/metrics etc).

intrumentation -> instrumentation

# Register the instrumentation handlers (/metrics etc).

What happened?
I wanted to configure my kubeadm-like cluster to get monitored by prometheus-operator. I started using the following file:

apiVersion: kubeadm.k8s.io/v1alpha1
kind: MasterConfiguration
api:
  advertiseAddress: 192.168.1.173 (I changed the IP from here)
  bindPort: 6443
authorizationModes:
- Node
- RBAC
certificatesDir: /etc/kubernetes/pki
cloudProvider:

What did you expect to see?

I'm expecting to be able to filter out the requests from blackbox exporter in my access logs.
So, please, add a user agent header that container the "blackbox exporter" string somewhere.

What did you see instead?

I see User-Agent: Go-http-client/1.1
Not easy to filter in the access logs...

It would be awesome if the metrics could include the node's topology.kubernetes.io/region & topology.kubernetes.io/zone (not sure what the non-AWS fields are called). That would help quickly identify patterns in the results. e.g., zone "a" is slower than zone "b" or that cross-zone traffic is what's causing a large spike in response times. Not sure if this is possible within the framework of this
