watch-duck 1.0.0

Personal python toolbox to track progress of ecflow experiments

watch-duck

Toolbox to monitor the progress of ecflow experiments.

Installation

Install using pip:

$ pip install watch-duck

For some functionalities (see below), you need to install sitesctl from here.

Usage

Configuration

When running, watch-duck reads the config file ~/.config/watch-duck.toml. The file is organised in sections, each one being associated to a specific command, except for the main section, which is used in all commands to provide the working directory:

[main]
wdir = '/path/to/the/working/directory'

In the following, the path to the working directory will simply be called /wdir.

Commands

Get status

On the HPC, use the following command to get the state of a given ecflow suite in a log file:

ecflow_client --host=<host> --get_state=<suite> "/wdir/log/<suite>_$(date +%Y_%m_%d_%H_%M_%S).log"

where <suite> should be replaced by the suite (eg. daaf) that you want to monitor and <host> by the host of the given suite (eg. ecflow-pifs-rd-f-1).

You need to run this command at least once per hour to get a proper report. Note that if you do so using hpc-cron, you would need to run

source /etc/profile
module load ecflow

before you are able to use ecflow_client.

Parse

On the HPC, use the following command to parse the log files stored in /wdir/log/:

watch-duck parse

The progress and state of each experiment will be stored in dedicated zarr archives: /wdir/progress/<exp>.zarr and /wdir/state/<exp>.zarr.

For this command, you need to provide the following config:

[parse]
chunk_size_state = 128
chunk_size_progress = 128
suites = [
    'daaf',
]
exclude_experiments = [
]
exclude_experiment_types = [
    'fc50',
    'unknown',
]

where you can specify:

• the zarr chunk size (over time) of the progress and state archives;
• the list of suites that you want to monitor;
• the list of experiments to ignore;
• the list of experiment types to ignore.

Ideally, you should call this command each time you produced new log files, e.g. using hpc-cron.

Report

On the HPC, use the following command to produce a short report about the active experiments:

watch-duck parse

This will read the progress archive of each active experiment and write a short report of the progress over the last 10 days (subsampled to a 1-hour frequency) in /wdir/report.h5.

For this command, you don't need to provide further config.

Ideally, you should call this command each time you updated the progress archive, e.g. using hpc-cron.

Upload

On the HPC, use the following command to upload the latest report to the specified website:

watch-duck upload

For this command, you need sitesctl and you need to provide the following config:

[site]
space = '<space>'
name = '<name>'

where <space> and <name> correspond to the space and name of the website.

Ideally, you should call this command each time you updated the report, e.g. using hpc-cron.

Download

On any device, use the following command to download the latest report from the specified website:

watch-duck download

For this command, you need sitesctl and you need to provide the following config:

[site]
space = '<space>'
name = '<name>'

where <space> and <name> correspond to the space and name of the website.

Ideally, you should call this command before showing a summary.

Summary

On any device, use the following command to show a summary of the latest report:

watch-duck show

Use the help option to show all available options (in particular how to show the progress only for a given suite or experiment type).

For this command, you need to provide the following config:

[summary]
delta_t = '48h'
exclude_aborted = true
exclude_suspended = true
vref_fc = 25
vref_lw = 4
vref_elda = 4

where you can specify:

• some parameters to compute the instantaneous speed of the experiments (averaging period, and whether to excluded times where the experiment was aborted or suspended);
• the reference speed for each experiment type (used to set the upper limit of the colour scale).

Finished

On any device, use the following command to show the list of experiments that recently finished (from the latest report):

watch-duck finished

For this command, you don't need to provide further config.

Show

The show command is simply a concatenation of the download (optional), summary, and finished commands.

Iver

On the HPC, use the following command to compute the IVER scores of compatible fc experiments:

watch-duck iver

For each IVER configuration, this will use IVER to (1) download the forecasts of the compatible fc experiments that are still ongoing and (2) compute the IVER scores of the compatible fc experiments that recently finished.

For this command, for each IVER configuration, you need to provide the following config:

[iver.<profile>]
version = 3.17
date_start = '2025-01-01'
date_end = '2025-12-31'
date_freq = 48

where you can specify:

• the name of the IVER profile, as the name of the subsection;
• the IVER version;
• the start and end date of the forecasts;
• the frequency (in hours) between forecasts.

Ideally, you should call this command on a regular basis, typically once a day, e.g. using hpc-cron.

Clean

On the HPC, use the following command to clean old and temporary files:

watch-duck clean

For this command, you don't need to provide further config, but you need to provide the IVER configuration (see above) if you want to clean IVER's temporary files.

Ideally, you should call this command on a regular basis, typically once a day, e.g. using hpc-cron.

Summary

On the HPC, every hour you should call:

• ecflow_client to get the state of the suites;
• the parse command;
• the report command;
• the upload command;

and every day you shoud call:

• the iver command;
• the clean command.

NB: if you are only interested in the following suites: daaf, dae, dav, nemc, these are already covered by daaf, and you can skip this first step. Just make sure to set your /wdir to daaf's /wdir if you are on the HPC, or to use daaf's iver site if you are on any other device.

Then, on any device, you can call at any time:

• the download command (you don't need this if you are on the HPC);
• the summary command;
• the finished command.
