vmagent

Send data to Last9 via VictoriaMetrics vmagent using Prometheus Remote Write protocol

We make use of the VictoriaMetrics' vmagent remote-write to write to an external remote endpoint i.e. Last9's remote-write endpoint.

Prerequisites​

Create a Last9 cluster by following Getting Started.

Keep the following information handy after creating the cluster:

  • $levitate_remote_write_url - Last9's Remote write endpoint
  • $levitate_remote_write_username - Cluster ID
  • $levitate_remote_write_password - Write token created for the cluster

Sending data to Last9​

The information flow is as follows:

Sending metrics to Last9 via vmagent

Setup​

Here is a sampledocker-compose.yaml for the vmagent setup:

version: "3.5"
services:
  vmagent:
    container_name: vmagent
    image: victoriametrics/vmagent
    ports:
      - 8429:8429
    volumes:
      - vmagentdata:/vmagentdata
      - /var/tmp:/var/tmp
      - ./vmagent.yaml:/etc/vmagent/vmagent.yaml
    command:
      - "--promscrape.config=/etc/vmagent/vmagent.yaml"
      - "--remoteWrite.tmpDataPath=/var/tmp/vmagent/"
      - "--remoteWrite.maxDiskUsagePerURL=10737418240"
      - "--remoteWrite.url=$levitate_remote_write_url"
      - "--remoteWrite.basicAuth.username=$levitate_remote_write_username"
      - "--remoteWrite.basicAuth.password=$levitate_remote_write_password"
    restart: always
    network_mode: "host"
volumes:
  vmagentdata: { }

Create vmagent.yaml to add a sample scrape config. Replace this scrape config with your desired config:

global:
  scrape_interval: 1m
  scrape_timeout: 20s

# Check https://prometheus.io/docs/prometheus/latest/configuration/configuration for more details
scrape_configs:
  - job_name: "vmagent"
    static_configs:
      - targets: [ "localhost:8429" ]

This will run the vmagent container, scrape the desired targets, and remote write metrics to Last9.

Verification​

The Last9 Cluster will start showing a summary of ingested samples.
