Moneo is a distributed GPU system monitor for AI workflows. It orchestrates metric collection (DCGMI + Prometheus DB) and visualization (Grafana) across multi-GPU/node systems. This provides useful insights into workflow and system level characterization.

Moneo offers flexibility with 3 deployment methods:

1. The preffered method using Azure Managed Prometheus/Grafana and Moneo linux services for collection (Headless deployment)
2. Using Azure Application Insights/Azure Monitor Workspace(AMW) (Headless deployment w/ App Insights).
3. Using Moneo CLI with a dedicate headnode to host local Prometheus/Grafana servers (Local Grafana Deployment)

Moneo Headless Method:

• python >=3.7 installed

• OS Support:

  • Ubuntu 18.04, 20.04, 22.04
  • AlmaLinux 8.6

Note: Not applicable if using Azure Managed Grafana/Prometheus

• docker 20.10.23 (May work with other versions but this has been tested.)
• parallel-ssh 2.3.1-2 (May work with other versions but this has been tested.)
• Manager node must be able to ssh to itself

• Nvidia Architecture supported (only for Nvidai GPU monitoring):
  • Volta
  • Ampere
  • Hopper
• Installed with install script at time of deployment (If not installed):
  • DCGM 3.1.6 (For Nvidia deployments)
  • Check install scripts for the various python packages installed.

Get the code:

• Clone Moneo from Github.

      # get the code
      git clone https://github.com/Azure/Moneo.git
      cd Moneo
      # install dependency
      sudo apt-get install pssh

  Note: If you are using an Azure Ubuntu HPC-AI VM image you can find the Moneo in this path: /opt/azurehpc/tools/Moneo

The preffered way to deploy Moneo is the headless method using Azure Managaed Grafana and Prometheus resources.

Complete the steps listed here: Headless Deployment Guide

This method requires a deploying of a head node to host the local Prometheus database and Grafana server.

• The headnode must have enough storage available to facilitate data collection
• Grafana and Prometheus is accessed via web browser. Ensure proper access from web browser to headnode IP.

Complete the steps listed here: Local Grafana Deployment Guide

Moneo CLI provides an alternative way to deploy and update Moneo manager and worker nodes. Although linux services are preffered this offeres an alternative way to control Moneo.

• python3 moneo.py [-d/--deploy] [-c hostfile] {manager,workers,full}
• python3 moneo.py [-s/--shutdown] [-c hostfile] {manager,workers,full}
• python3 moneo.py [-j JOB_ID ] [-c hostfile]
• i.e. python3 moneo.py -d -c ./hostfile full

Note: For more options check the Moneo help menu

    python3 moneo.py --help

• For Azure Managed Grafana the dashboards can be accessed via the endpoint provided on the resource overview.
• For Moneo CLI deployment with a dedicated head node the Grafana portal can be reached via browser: http://master-ip-or-domain:3000
• If Azure Monitor is used navigate to the Azure Monitor Workspace on The Azure portal.

• NVIDIA exporter may conflict with DCGMI

  There're two modes for DCGM: embedded mode and standalone mode.

  If DCGM is started as embedded mode (e.g., nv-hostengine -n, using no daemon option -n), the exporter will use the DCGM agent while DCGMI may return error.

  It's recommended to start DCGM in standalone mode in a daemon, so that multiple clients like exporter and DCGMI can interact with DCGM at the same time, according to NVIDIA.

  Generally, NVIDIA prefers this mode of operation, as it provides the most flexibility and lowest maintenance cost to users.

• Moneo will attempt to install a tested version of DCGM if it is not present on the worker nodes. However, this step is skipped if DCGM is already installed. In instances DCGM installed may be too old.

  This may cause the Nvidia exporter to fail. In this case it is recommended that DCGM be upgrade to atleast version 2.4.4. To view which exporters are running on a worker just run ps -eaf | grep python3

1. For Managed Grafana (headless) deployment

   • Verify that the user managed identity is assigned to the VM resource.
   • Verify the the prerequisite configure file (Moneo/src/worker/publisher/config/managed_prom_config.json) is configured correctly on each worker node.
   • On the worker nodes verify functionality of prometheus agent remote write:
     • Check prometheus docker with sudo docker logs prometheus | grep 'Done replaying WAL' It will have the result like this:

       ts=2023-08-07T07:25:49.636Z caller=dedupe.go:112 component=remote level=info remote_name=6ac237 url="<ingestion_endpoint>" msg="Done replaying WAL" duration=8.339998173s

   • Check Azure Grafana's is linked to Azure Prometheus workspace.
     • This can be done by accessing settings in Grafana dashboard and ensuring the ingestion link for the Managed Prometheus is being used for the datasource url.
     • You can also verify The Managed Prometheus resource in the portal is linked with the managed Grafana resource

2. For deployments with a Headnode:

   • Verifying Grafana and Prometheus containers are running:
     • Check browser http://master-ip-or-domain:3000 (Grafana), http://master-ip-or-domain:9090 (Prometheus)
     • On Manager node terminal run sudo docker container ls

3. All deployments:

   • Verifying exporters on worker node:

     • ps -eaf | grep python3
