dmtri

dmtri is a command-line tool designed to trigger metadata and data refresh simulations across EIDA nodes using Ansible automation.

• seedpsd
• wfcatalog
• availability

It uses .dmtri_jobs.json per host to track async job state and integrates with uv and ansible for CLI automation.

Installation & Setup

1. Install or Run

You can run dmtri directly or install it as a tool:

Run without installing (via uvx)

uvx dmtri <command>

Install as a global tool

# Using uv (recommended)
uv tool install dmtri

# Using pip
pip install dmtri

2. Configure

Once installed, set up your local configuration directory:

dmtri init

This creates a config folder (e.g., ~/.config/dmtri/ on Linux) with a template hosts.ini and all standard playbooks.

Edit your Inventory

Use nano (or any text editor) to fill in your EIDA server details:

nano ~/.config/dmtri/hosts.ini

Verify Connectivity

Check if your servers are reachable:

dmtri doctor

Usage

Run Refresh Jobs

Trigger refresh playbooks across your nodes:

dmtri refresh --network HL --station ATH --starttime 2024-01-01

Track Job Status

Monitor the status of asynchronous jobs:

dmtri track

Fix Inconsistencies

Automatically repair the inconsistencies found in an eida-consistency report. A report lists streams where the availability view and dataselect disagree; dmtri fix reads that report and, for each affected stream, re-runs the WFCatalog collector and rebuilds the availability view for the exact time window.

Point it at a report file or URL:

dmtri fix https://eida-oculus.orfeus-eu.org/consistency/NOA/2026/NOA_2026-06-07_140510.json

Fix only specific entries from the report (by their index):

dmtri fix report.json --index 2 --index 16

After a fix, the availability service keeps cached answers for ~20 minutes, so a stream may still look unfixed for a short while. Re-check once the cache expires — this only verifies, it changes nothing:

dmtri fix --verify-only report.json

Prerequisite: the eida-consistency CLI

dmtri fix reads the report through eida-consistency (version 0.5.1 or newer, for its explore --json output). If it isn't already on the machine, install it any one of these ways:

uv tool install eida-consistency     # recommended — puts it on your PATH
pipx install eida-consistency
pip install eida-consistency

You don't strictly have to install it: if uv is present, dmtri fix will run it on demand via uvx eida-consistency. And if it's installed somewhere off your PATH, point dmtri at it:

export DMTRI_EIDA_CONSISTENCY='/full/path/to/eida-consistency'

If it's missing (or too old), dmtri fix stops before touching anything and prints the exact install/upgrade command to run.

Customization

Local Playbooks

dmtri init copies all playbooks to your config directory. You can edit them to change automation logic:

# Location: ~/.config/dmtri/playbooks/
nano ~/.config/dmtri/playbooks/refresh/availability_refresh.yml

dmtri prioritizes these local playbooks over the bundled defaults.

Inventory Overrides

Override the inventory at runtime:

dmtri doctor --inventory ./my_custom_hosts.ini

Operation Details

dmtri supports two main operations for both metadata and data: refresh and clean. These affect the following components:

🔄 Refresh

• Metadata

  • seedpsd: Scans for new metadata.
  • availability: Refreshes the view in MongoDB.

• Data

  • Identifies data files in the archive for the specified epoch (by NSLC and time range).
    • seedpsd: Recalculates seedPSD for new files.
    • wfcatalog: Runs the collector on new data files.

🧹 Clean

• Metadata

  • seedpsd: Removes the metadata entries.
  • availability: Refreshes the view in MongoDB.

• Data

  • Identifies data files in the archive for the specified epoch.
    • seedpsd: Removes associated seedPSD data (via CLI).
    • wfcatalog: Removes files using the --delete option in the collector.
