Configuring telemetry collectors

In privileged EXEC mode, enter configure terminal.
```
device# configure terminal
```
Enter the telemetry collector command, specifying a collector name.
```
device(config)# telemetry collector collector_1
```
Enter the ip port command, specifying the IPv4 address and port of the collector.
```
device(config-collector-collector_1#) ip 10.168.112.10 port 1
```

Enter the profile command to add one or more telemetry profiles.

device(config-collector-collector_1)# profile system-profile  default_system_utilization_statistics
device(config-collector-collector_1)# profile interface-profile default_interface_statistics

To specify a VRF context other than mgmt-vrf, enter the use-vrf command.

Enter the encoding command to specify the encoding format.

device(config-collector-collector_1)# encoding ?
Possible completions:
  gpb    Google protobuf encoding
  json   JSON encoding
device(config-collector-collector_1)# encoding json

Enter the activate command to activate the collector.
```
device(config-collector-collector_1)# activate
```

To confirm the configuration, enter the show running-configuration telemetry collector command.

device(config-collector-collector_1)# do show running-configuration telemetry collector
telemetry collector <collector-profile-1>
  ip <ipv4address1> port <portNum>
  profile system-utilization default_system_utilization_statistics
  profile interface default_interface_statistics
  use-vrf mgmt-vrf
  encoding json
  activate

To display the status of a telemetry collector, enter the show telemetry collector command.

device(config-collector-collector_1)# do show telemetry collector collector_1 
Telemetry data is streamed to collector_1 on 10.128.116.10 and port 1, with transport as tcp.

Profiles Streamed                      Interval   Uptime      Last Streamed
-------------------                    ---------  ----------  ---------------
default_interface_statistics           120 sec    05/10:23    2017-01-15: :05:07:33
default_system_utilization_statistics  300 sec    05/10:23    2017-01-15: :05:07:33
!

To display the status of active telemetry collector sessions, enter the show telemetry collector summary command.

device# show telemetry collector summary
Activated Collectors:
--------------------
Name              IP Address:Port       Streaming/Connection Status
-------------     --------------------  ---------------------------

The following example configures and activates a telemetry collector.

device# configure terminal
device(config)# telemetry collector collector_1 
device(config-collector-collector_1)# profile system-profile default_system_utilization_statistics
device(config-collector-collector_1)# profile interface-profile default_interface_statistics
device(config-collector-collector_1)# ip 10.168.112.10 port 1
device(config-collector-collector_1)# encoding json 
device(config-collector-collector_1)# activate
