Install Loki

Loki is an open platform for collecting, indexing, and storing logs. It enables debugging and problem detection in the system based on log data analysis and monitoring.

Beforehand, install the monitoring tools.

The installation of Loki consists of five steps:

When installing Loki + Tempo, start with the Loki addon. This allows preserving cross-linking settings, as they are initially configured in the Datasource settings.

Step 1: Download the Helm chart and the configuration file

To install over the internet, obtain the configuration file values- loki.yaml by executing the command:

helm repo add elma365 https://charts.elma365.tech
helm repo update
helm show values elma365/loki > values-loki.yaml

Getting configuration file for installation in a closed environment without internet access,

Step 2: Create buckets and set lifecycle rules in MinIO

1. Create alias for MinIO:

mc alias set my_alias http://minio.local accessKey secretKey

2. Create buckets with the names admins, chunks and rules:

mc mb -p my_alias/admin --region=ru-central-1
mc mb -p my_alias/chunks --region=ru-central-1
mc mb -p my_alias/rules --region=ru-central-1

3. Set lifecyle for chunks, deleting objects older than 60 days:

mc ilm import my_alias/chunks <<EOF
{
  "Rules": [
      {
          "Expiration": {
          "Days": 60
          },
          "ID": "Delete objects from the Loki bucket older than 60 days",
          "Status": "Enabled"
          }
  ]
}
EOF

Step 3: Fill in the configuration file

Fill in the values-loki.yaml configuration file to install Loki
