IOS XR Telegraf testing

Getting started with Telegraf and IOS XR Streaming Telemetry.

Installing Telegraf

  • Install Go
wget https://dl.google.com/go/go1.12.7.linux-amd64.tar.gz
sudo rm -rf /usr/lib/go
sudo tar -C /usr/local -xzf go1.12.7.linux-amd64.tar.gz
export GOROOT=/usr/local/go
export PATH=$PATH:$GOROOT/bin

Validate with go version.

  • Install Dep
go get -d -u github.com/golang/dep 
cd $(go env GOPATH)/src/github.com/golang/dep
DEP_LATEST=$(git describe --abbrev=0 --tags) 
git checkout $DEP_LATEST
go install -ldflags="-X main.version=$DEP_LATEST" ./cmd/dep 
git checkout master
  • Build Telegraf
dep ensure -vendor-only
export GO111MODULE=on
export GOPROXY=https://proxy.golang.org
go build -mod=vendor ./cmd/telegraf

Config: telegraf.conf.

Run InfluxDB

  • Run it on a Docker Container
docker run -p 8086:8086 \
    -v $PWD:/var/lib/influxdb \
    influxdb

Modify $PWD to the directory where you want to store data associated with the InfluxDB container.

  • Create a DB
export MDT_DURATION=168
export MDT_SHARD=6
MDT_DB=`echo q=CREATE DATABASE mdt_db WITH DURATION ${MDT_DURATION}h SHARD DURATION ${MDT_SHARD}h`
curl -s -XPOST http://localhost:8086/query --data-urlencode "$MDT_DB"

Validate with: curl -s -XPOST http://localhost:8086/query --data-urlencode "q=show databases".

Run Grafana

docker run \
  -d \
  -p 3000:3000 \
  --name=grafana \
  -e "GF_INSTALL_PLUGINS=grafana-clock-panel,grafana-simple-json-datasource,briangann-gauge-panel" \
  -e "GF_SECURITY_ADMIN_PASSWORD=secret" \
  grafana/grafana

Grafana is now at: http://<host ip>:3000 (admin/secret). Need to add InfluxDB as a data source.

Run Telegraf

Execute this: ./telegraf --config telegraf.conf.

Create Dashboard

Use dashboard.json.

Querying the DB for troubleshooting

$ curl -G 'http://localhost:8086/query?pretty=true' --data-urlencode "db=mdt_db" --data-urlencode "epoch=ms"  --data-urlencode "q=SELECT max(\"total-cpu-one-minute\") FROM \"Cisco-IOS-XR-wdsysmon-fd-oper:system-monitoring/cpu-utilization\""
