Telegraf troubleshooting
telegraf is an open source collector written in GO.
Telegraf collects data and writes them into a database.
It is plugin-driven (it has input plugins, output plugins, ...)
Heathbot uses telegraf to collect data using SNMP (SNMP input plugin) and write the data collected to influxdb (influxdb output plugin).
If you are looking for healthbot configuration examples to collect data using SNMP, you can refer to these demos described in the wiki page Healthbot CLI and Healthbot REST calls with Python
This section can be useful for troubleshooting purpose.
ssh to healthbot and run this command to list telegraf containers
$ docker ps | grep telegraf
Start a shell session in an telegraf container
$ docker exec -it <container-id> bash
