Flux Power Monitor

The Flux Power Monitor is a lightweight telemetry module for the Flux resource manager designed to provide job-level power statistics. It aggregates power data over time for each node and its respective hardware components based on the provided jobId.

Dependencies

Flux Power Monitor depends on:

1. Flux-core: Must be installed on the system.

2. Variorum: For power data collection. Installation steps are available here.

3. Flux Python Bindings: Install with the command:

   pip install flux-python
   

The module is built using Autotools.

Building the Module

To build the Flux Power Monitor, follow these steps:

1. ./autogen.sh
2. Configure the build specifying the Variorum and Flux paths:

./configure --with-variorum=<path_to_variorum> --prefix=<path_to_flux>

3. make -j32

Usage

To utilize the Flux Power Monitor:

1. Load the module:

./scripts/load_power_monitor.sh -s <buffer_size> -r <sampling_rate>

• -s: Buffer size (amount of power data each node stores).
• -r: Sampling rate for data collection.

2. Confirm the module is loaded with:

flux module list

3. Retrieve power data for a specific job using:

python power_query.py -j {jobId}

4. To unload the module:

./scripts/unload_power_monitor.sh
