telegraf log wrangling see https://www.influxdata.com/time-series-platform/telegraf/ for more details on teleraf

Quick Start

create env file

cp .env.sample .env

edit .env values. This to check are

• LOG_FILE - this should point to the nginx or apache log folder. not directly to a file.
• HOST_URL - hostname to report in plausible with protocol
• DOMAINS - keys used by plausible to route events see https://plausible.io/docs/events-api#request-body-json-parameters
• PLAUSIBLE_URL - url to plausible instance
• SENTRY_URL - url to sentry project for monitering up time

review telegraf/telegraf.conf. the most important one being

• files under [[inputs.tail]]

find the group that has read access to the log files

stat -c '%g' /var/log/apache2

use the resulting number to set the group in the telegraf container by editing the docker compose and adding

user: telegraf:4

where 4 is the gid of the group

Start the container

sudo docker-compose up -d

TODO

• create a telegraf conf for nginx
• log file name is hard coded i.e. catalogue-ssl-access.log. it would be nice to make it based on an environment variable.
