The idea is to collect logs from all nodes

Prerequisites:

• Change Your Docker log diver to journald

kubectl apply -f namespace.yaml
kubectl apply -f roles.yaml
kubectl apply -f influxdb.yaml
kubectl apply -f telelog.yaml
kubectl apply -f chronograf.yaml
kubectl apply -f kapacitor.yaml
kubectl apply -f stress.yaml

or if you're a one liner:

kubectl apply -f namespace.yaml -f roles.yaml -f influxdb.yaml -f telelog.yaml -f chronograf.yaml -f kapacitor.yaml -f stress.yaml

Finally to access Chronograf from within our local browser we need the following port forward.

kubectl port-forward svc/chronograf -n logging 8888:80

Go to localhost:8888 now!

Developing the Kapacitor UDF

File docker-compose.yaml is useful during the development and debugging of the Kapacitor UDF.

To make it working do not forget to forward the port of the influxdb within minikube.

kubectl port-forward svc/influxdb -n logging 8686:8686

Then run

docker-compose up -d

Other suitable docker log drivers

It is possible to use this with syslog docker log driver with following log options:

• syslog-format=rfc5424micro
• syslog-address=udp://1.2.3.4:1111 (telegraf syslog plugin)

In such case:

• there is not need for rsyslog
• telegraf syslog plugin in UDF mode (at the moment in TCP/TLS mode there is not way to disable octet framing requirement - ie., RFC5425)
• syslog facility will be fixed (depending on the syslog-facility option)
