Monitoring web app

Launch the monitoring web app locally

The main entry point to the monitoring app is the ~/.bts_tools/config.yaml file. You should edit it first and set the values to correspond to your delegate’s configuration. See the Format of the config.yaml file page for details.

If this file doesn’t exist yet, run the tools once (for instance: bts -h) and it will create a default one.

To run the debug/development monitoring web app, just do the following:

$ bts monitor

and it will launch on localhost:5000.

Setting up on a production server

For production deployments, it is recommended to put it behind a WSGI server, in which case the entry point is bts_tools.wsgi:application.

Do not forget to edit the ~/.bts_tools/config.yaml file to configure it to suit your needs.


We will run the monitoring tools using nginx as frontend. Install using:

# apt-get install nginx uwsgi uwsgi-plugin-python3

The tools will have to be run from a virtualenv, so let’s create it:

$ mkvirtualenv -p `which python3` bts_tools
$ pip3 install bts_tools

Edit the following configuration files:

/etc/uwsgi/apps-available/bts_tools.ini (need symlink to /etc/uwsgi/apps-enabled/bts_tools.ini)

uid = myuser
gid = mygroup
chmod-socket = 666
plugin = python34
virtualenv = /home/myuser/.virtualenvs/bts_tools
enable-threads = true
lazy-apps = true
workers = 1
module = bts_tools.wsgi
callable: application


The important, non-obvious, fields to set in the uwsgi config file are the following:

  • set enable-threads = true, otherwise you won’t get the monitoring thread properly launched
  • set lazy-apps = true, otherwise the stats object will not get properly shared between the master process and the workers, and you won’t get any monitoring data
  • set workers = 1, otherwise you will get multiple instances of the worker thread active at the same time

The virtualenv field also needs to be setup if you installed the tools inside one, otherwise you can leave it out.

/etc/nginx/sites-available/default (need symlink to /etc/nginx/sites-enabled/default)

server {
        listen 80;
        charset utf-8;
        location / { try_files $uri @bts_tools; }
        location @bts_tools {
                # optional password protection
                #auth_basic "Restricted";
                #auth_basic_user_file /home/myuser/.htpasswd;
                include uwsgi_params;
                uwsgi_pass unix:/run/uwsgi/app/bts_tools/socket;

After having changed those files, you should:

# service uwsgi restart
# service nginx restart

Monitoring multiple instances (ie: running on different hosts) at the same time, to have an overview while running backup nodes and re-compiling your main node:
