This project is developed as part of the HPE CPP 2025 initiative, focused on implementing log observability and visualization at scale for HPE's massive server infrastructure. Named HPCM Logs, the solution is designed to enable efficient collection, processing, aggregation, and querying of logs using open-source observability tools like Fluent Bit, Apache Kafka, Logstash, Grafana Loki, VictoriaLogs, and Grafana.
Logs from various sources are streamed through a pipeline of industry-standard tools to ensure scalability, reliability, and easy visualization:
- Fluent Bit – Lightweight log collector and forwarder
- Apache Kafka – Message queue for buffering and scalable distribution
- Logstash – Optional log processor and modifier
- Grafana Loki / VictoriaLogs – Log aggregation and storage backends
- Grafana – Dashboard for querying and visualizing logs
Make sure the following tools are installed on your Linux system:
Fluent Bit Apache Kafka Logstash Grafana Loki or VictoriaLogs Grafana
📝 Note: The exact paths may vary depending on where you've cloned or installed each tool. Adjust paths as needed.
🔹 Step 1: Start Fluent Bit: This step collects logs and forwards them to Kafka. fluent-bit -c ./fluentbit/fluent-bit.conf Make sure fluent-bit.conf is configured correctly with source paths and Kafka topic mappings.
🔹 Step 2: Start Apache Kafka
🔹 Step 3: Start Logstash: Logstash can modify logs, extract fields, or enrich data before forwarding to Loki or VictoriaLogs. logstash -f ./logstash/logstash.conf
🔹 Step 4: Start Log Aggregator: Choose one of the following:
- Option A: Grafana Loki ./loki -config.file=./loki/loki-config.yaml
- Option B: VictoriaLogs ./vmlogs-prod -config=./vmlogs/vmlogs.yaml
🔹 Step 5: Start Grafana: Visit http://localhost:3000 and: Add Loki or VictoriaLogs as a data source Import the dashboard provided in the repo and visualize
