Enabling Tempo¶

Introduction¶

Tempo is a distributed tracing backend designed to ingest and store traces efficiently without requiring indexing. It allows developers to troubleshoot and analyze request flows across microservices. It stores traces in an efficient manner, reducing infrastructure and operational costs. Also, it is designed to handle high volumes of trace data with minimal overhead.

Prerequisites¶

Ensure that the following prerequisites are met.

1. You will need a S3 bucket to save the log traces.
2. Your Node IAM role should have permission to access the S3 bucket.

Process¶

To enable Tempo 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 Tempo.

     Bash
     1	TEMPO_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
