Cisco model-driven telemetry (MDT)
Cisco model-driven telemetry (MDT) is an input plugin that consumes
telemetry data from Cisco IOS XR, IOS XE and NX-OS platforms. It supports TCP & GRPC dialout transports.
RPC-based transport can utilize TLS for authentication and encryption.
Telemetry data is expected to be GPB-KV (self-describing-gpb) encoded.
The GRPC dialout transport is supported on various IOS XR (64-bit) 6.1.x and later, IOS XE 16.10 and later, as well as NX-OS 7.x and later platforms.
The TCP dialout transport is supported on IOS XR (32-bit and 64-bit) 6.1.x and later.
Configuration:
[[inputs.cisco_telemetry_mdt]]
## Telemetry transport can be "tcp" or "grpc". TLS is only supported when
## using the grpc transport.
transport = "grpc"
## Address and port to host telemetry listener
service_address = ":57000"
## Grpc Maximum Message Size, default is 4MB, increase the size.
max_msg_size = 20000000
## Enable TLS; grpc transport only.
# tls_cert = "/etc/telegraf/cert.pem"
# tls_key = "/etc/telegraf/key.pem"
## Enable TLS client authentication and define allowed CA certificates; grpc
## transport only.
# tls_allowed_cacerts = ["/etc/telegraf/clientca.pem"]
## Define (for certain nested telemetry measurements with embedded tags) which fields are tags
# embedded_tags = ["Cisco-IOS-XR-qos-ma-oper:qos/interface-table/interface/input/service-policy-names/service-policy-instance/statistics/class-stats/class-name"]
## Define aliases to map telemetry encoding paths to simple measurement names
