The ifname
plugin looks up network interface names using SNMP.
Telegraf minimum version: Telegraf 1.15.0
[[processors.ifname]]
## Name of tag holding the interface number
# tag = "ifIndex"
## Name of output tag where service name will be added
# dest = "ifName"
## Name of tag of the SNMP agent to request the interface name from
# agent = "agent"
## Timeout for each request.
# timeout = "5s"
## SNMP version; can be 1, 2, or 3.
# version = 2
## SNMP community string.
# community = "public"
## Number of retries to attempt.
# retries = 3
## The GETBULK max-repetitions parameter.
# max_repetitions = 10
## SNMPv3 authentication and encryption options.
##
## Security Name.
# sec_name = "myuser"
## Authentication protocol; one of "MD5", "SHA", or "".
# auth_protocol = "MD5"
## Authentication password.
# auth_password = "pass"
## Security Level; one of "noAuthNoPriv", "authNoPriv", or "authPriv".

## Context Name.

## max_parallel_lookups is the maximum number of SNMP requests to
## make at the same time.
# max_parallel_lookups = 100
## ordered controls whether or not the metrics need to stay in the
## same order this plugin received them in. If false, this plugin
## may change the order when data is cached. If you need metrics to
## stay in order set this to true. keeping the metrics ordered may
## be slightly slower
# ordered = false
## cache_ttl is the amount of time interface names are cached for a
## given agent. After this period elapses if names are needed they
## will be retrieved again.
# cache_ttl = "8h"
