ViewBovis-stats

This repo provides code to visualise basic traffic and requests stats on APHA's ViewBovis web-app.

Installation

  • Requires at least python3, is tested on python3.10.
  • Recommend using a python virtual environment.
  • To install dependencies: pip install -r requirements.txt

Running

  1. Ensure that all stats files for each day you wish to visualise are downloaded to a single local directory. These files are .json format and saved on the ViewBovis server at /var/log/viewbovis/ with a naming convention like: viewbovis_requests_yyyy-mm-dd.json, you will need to copy these to your dev machine.
  2. In visualise.ipynb, update the variables stats_dir, start_date and end_date below to the location of where you have the stats, the start and end dates you wish to plot from and to respectively. Leaving start_date and end_date as None will plot the all dates that you have downloaded.
# set these values
stats_dir = "/home/nickpestell/tmp/viewbovis_stats/"
start_date = None
end_date = None
  1. To run the jupyter notebook:
jupyter nbconvert --execute visualise.ipynb --to markdown --output <your-outfile-name>

This will create a markdown that looks much the same as this readme.md

Output

This outputs a bar chart as seen below showing frequency of visits to ViewBovis and its associated API requests on a daily basis.

There are five suplots:

  1. "/" - homepage (i.e. the number of times the app was visited)
  2. "/sample" - cattle movement requests
  3. "/sample/related" - SNP distance map requests
  4. "/sample/matrix" - SNP matrix requests
  5. "/charon/getDataset" - Nextstrain searches

Code

import utils
def bar_chart(df_stats, start_date=None, end_date=None):
    if start_date==None:
        start_date = df_stats.index[0]
    if end_date==None:
        end_date = df_stats.index[-1]
    return df_stats.loc[start_date:end_date].plot.bar(figsize=(16, 10), subplots=True, rot=80)
df_stats = utils.build_stats_df(stats_dir)
axs = bar_chart(df_stats)
for ax in axs:
    for i, t in enumerate(ax.get_xticklabels()):
        if (i % 7) != 0:
            t.set_visible(False)
