COVID-19 Tracking Using Telegraf and InfluxDB Dashboards

A group of interns at InfluxData developed a platform that tracks real-time COVID-19 data from across the United States. The project aimed to make critical information about COVID-19 more accessible, including vaccination rates and the number of positive cases for a given location. They used Telegraf to ingest data systematically and in a repeatable fashion, and InfluxDB Cloud free service to query and visualize their data. The interns created three dashboards for their graphs and maps, showing statistics on COVID-19 cases and deaths alongside the percentage of fully vaccinated people, number of deaths and confirmed cases in each county, and vaccination rates of each state. They also set up four different Telegraf configurations to pull in data from various API endpoints. The project faced challenges such as cardinality and query write limit issues, but they were able to overcome them with effective communication and help from mentors.
