 ### Prerequisites

 1. **Clone the repository:**
 
-    ```bash
+```bash

-### Log Analyser
 
-1. **Add your log files:**
+2. **Update Jitsi Meet Docker Compose Configuration:**
 
-   Place your log file in the `log-analyser/jitsi-logs` directory. Update the `otel-collector-config.yaml` file with the correct file path to start ingesting the logs. This setup allows OpenTelemetry to read logs from the file and forward them to Loki.
+To enable log collection and analysis, you need to modify the `docker-compose.yml` file for Jitsi Meet components. Add the following configuration to each Jitsi service within the `docker-compose.yml` file:
 
-2. **Update the otel-collector-config.yaml file:**
+```yaml
+    logging:
+      driver: "json-file"
+      options:

+```
 
-   Update the file path to point to your log file for ingestion by OpenTelemetry.
+This configuration ensures that logs are collected in JSON format and tagged with service labels, which is essential for Loki to properly ingest and index the logs.
 
 3. **Start the Docker containers:**
 
-   ```bash
+   To start all necessary services, including Jitsi Meet components, Grafana, Loki, and OpenTelemetry, run:
-   docker-compose -f docker-compose.yml -f log-analyser.yml up -d
-    ```

-### Grafana

-1. **Start the Docker container:**
 
     ```bash
-   docker-compose -f docker-compose.yml -f grafana.yml up -d
+    docker-compose -f docker-compose.yml -f log-analyser.yml -f grafana.yml up -d
     ```
 
-2. **Access Grafana:**
+   - This command will start the Jitsi Meet components from `docker-compose.yml`, the log analysis tools from `log-analyser.yml`, and Grafana from `grafana.yml`. The logs from Jitsi Meet components will automatically be sent to Grafana through Loki.
+   - **Note:** To use only Grafana for visualization without log analysis, you can use just `grafana.yml` alone. However, for the complete log analysis project, you need both `log-analyser.yml` and `grafana.yml`.

-The dashboard setups are available as JSON files in the `log-analyser/grafana-dashboards` directory. You can import these JSON files into Grafana to use the pre-configured dashboards. In the future, we plan to automate this import process.
