OpenSRE integrates with Nextflow to provide step-level visibility into every process and container.
Once installed, it automatically detects all Nextflow processes and displays real-time metrics, performance traces, and cost data for each task.

​
Why use OpenSRE when running Nextflow pipelines

Many teams running Nextflow also rely on Seqera Platform to orchestrate and monitor workflows across different environments.
 Because both tools appear in the same setups, we’ve prepared an objective comparison that explains how OpenSRE and Seqera differ in focus and how they can complement each other effectively. You can read the full comparison here: OpenSRE vs Seqera Nextflow orchestrates complex scientific workflows efficiently, but it doesn’t provide full visibility into why certain tasks run slowly, stall, or waste compute. OpenSRE fills that gap:
  • Real-time insight into every process, container, and tool
  • Performance metrics (CPU, memory, I/O, GPU) per task
  • Automatic detection of idle or blocked tasks
  • AI-native logging for easy debugging and root-cause analysis
  • Works across local, HPC, or cloud environments without changes to your Nextflow code

​
Getting Started

​
Prerequisites

  • Nextflow installed and working (nextflow run hello test passes)
  • OpenSRE installed on your operating system

​
Just run your pipeline, OpenSRE will automatically attach

If OpenSRE is already installed on your operating system, you only need to enable the OpenSRE agent for pipelines that have not been run with OpenSRE before.
In that case, run the following command: 
sudo tracer init --token <your-token>
Go to our onboarding to get your own personal token
When running this command, you will be asked to name your pipeline for clear labeling in the dashboard.

​
Examples

Launch the OpenSRE demo workflow: 
sudo tracer demo
Or run any Nextflow pipeline as usual. Once the pipeline starts, open the OpenSRE dashboard, and you’ll see each Nextflow process as a timeline step updating in real time.
