1- I have an application wich is running on several servers.
2-This application provides a MIB with a lot of informations.
3-I want to collect informations from each instance (one per server) of that application using SNMP (via SNMP plugin).
Is it possible to realize this with only one telegraf agent ?
If not, is it possible to realize this with severals telegraf agents ?
You should be able to do this with one or many Telegraf agents. You could have a single Telegraf with either multiple snmp plugins or multiple agents defined. It would also be possible to run a Telegraf instance on the host with the SNMP server that collects all stats for the server.
