Enabling Loki¶

Introduction¶

Loki is a log aggregation system designed for storing and querying logs efficiently. Unlike traditional log management systems, Loki indexes only metadata instead of the full log contents, making it highly scalable and cost-effective. Stores logs in a compressed format with minimal indexing, reducing storage and operational costs.

Configure S3 for Loki¶

Ensure that the following prerequisites are met.

1. You will need a S3 bucket to save the application logs.
2. Your node IAM role should have permission to access the S3 bucket.

Process¶

To enable Loki in the Privacera monitoring stack, follow the steps below.

1. SSH into the instance where Privacera Manager is installed.
2. Navigate to the config directory using the following command:

   Bash
   1	cd ~/privacera/privacera-manager/config/

3. Copy vars.monioring.yml file from sample-vars folder to custom-vars folder.

   If this file already exists in custom-vars folder then you can skip this step.

   Bash
   1	cp sample-vars/vars.monitoring.yml custom-vars/

4. Open vars.monioring.yml.

   Bash
   1	vi custom-vars/vars.monitoring.yml

5. Uncomment the below variables in the file and save it.

   • Provide the S3 buckte name.

     Bash
     1	MONITORING_S3_BUCKET_NAME: "<YOUR_S3_BUCKET_NAME>"

   • Enable Loki

     Bash
     1	LOKI_DEPLOYMENT_ENABLED: "true"

6. Once done, redeploy the monitoring components.

   a. Go to privacera-manager directory.

   Bash
   1	cd ~/privacera/privacera-manager.

   b. Run setup to generate the required files.

   Bash
   1	./privacera-manager.sh setup

   c. Install the monitoring components.

   Bash
   1	./pm_with_helm.sh install-monitoring

   d. Once done, run post-install.

   Bash
   1	./privacera-manager.sh post-install
