Remote reader do not support regex filtering in label

[dmitriy-lukyanchikov]

What did you do?

I run query like this
node_cpu_load{host_name=~".*"}

What did you expect to see?

metrics that stored on influxdb and prometheus local storage

What did you see instead? Under which circumstances?

Only metrics that stored locally inside Prometheus DB under its own retention policy

Environment

I run Prometheus with configured remote read and wright to influxdb 1.4

• System information:

Ubuntu 16.04.03
Linux 4.4.0-93-generic x86_64

• Prometheus configuration file:

# my global config
global:
  scrape_interval:     60s # By default, scrape targets every 15 seconds.
  evaluation_interval: 30s # By default, scrape targets every 15 seconds.
  scrape_timeout: 10s
  # 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).

# Load and evaluate rules in this file every 'evaluation_interval' seconds.

# 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.
  # Auto-discovery via consul tags by Registrator
  - job_name: 'federate_lr_metrics_node'
    scrape_interval: 30s

    honor_labels: true

@dmitriy-lukyanchikov Thanks for the report. You are saying you are using InfluxDB 1.4, but I don't think that version exists yet? (at least at https://github.com/influxdata/influxdb/releases, it only goes up to 1.3.7).

Are you using a version of InfluxDB that already has a built-in Prometheus remote read/write endpoint, or using an adapter?

[dmitriy-lukyanchikov]

@juliusv Hello! That version not released yet but you can build a docker image using this repository https://github.com/influxdata/influxdata-docker/tree/master/influxdb/nightly or use official site and download version named nightly, also in the link that you provide there is already 1.4 version https://github.com/influxdata/influxdb/releases/tag/v1.4.0

This version of InfluxDB already has built-in Prometheus remote read/write endpoint

[juliusv]

@dmitriy-lukyanchikov interesting, https://github.com/influxdata/influxdb/releases/tag/v1.4.0 just gives me a 404, and that tag also does not show for me in the list.

But I guess just checking with nightly would be sufficient.

[dmitriy-lukyanchikov]

hm strange indeed the error, ok try to use docker it works perfect for me, it builds in a minute without any problem

[AlekSi]

Can it be reproduced with released InfluxDB 1.4.x?

[brian-brazil]

Looks like this was resolved, and it would be an issue in InfluxDB rather than Prometheus anyway.
