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.
