 # wordpress_exporter
 Prometheus exporter for WordPress
 
-# Install wordpress_exporter
-```sh
-$ go get github.com/kotsis/wordpress_exporter
-```
-
-# Usage of wordpress_exporter
-```sh
-$ wordpress_exporter -wpconfig=/path/to/wp-config
-```
-or
-```sh
-$ wordpress_exporter -host=127.0.0.1 -port=3306 -user=uuuu -db=dddd -tableprefix=wp_ -pass=xxxx
-```
-
-It starts serving metrics at http://localhost:8888/metrics
-
-# Prometheus configuration for wordpress_exporter
-For Prometheus to start scraping the metrics you have to edit /etc/prometheus/prometheus.yml and add:
-
-```sh
-  - job_name: 'wordpress'
-    # metrics_path defaults to '/metrics'
-    # scheme defaults to 'http'.
-    static_configs:
-    - targets: ['localhost:8888']
-```
-
-the above is valid if the exporter runs at the same host as prometheus service. If prometheus runs
-in a docker container perhaps you will need to change localhost with the IP of the host system, something like 172.17.0.1
-
-# WordPress service with docker-compose
-
-Here is provided a quick WordPress service setup with docker-compose for testing the wordpress_exporter.
-You can go in $GOPATH/src/github.com/kotsis/wordress_exporter and run:
-```sh
-$ sudo docker-compose up -d
-```
-
-Now a wordpress is being served at : http://localhost:8000 where you must visit and create a user with a password.
-Then you can login in WordPress and create posts, users etc.
-
-Next you must start the wordpress_exporter
-```sh
-$ wordpress_exporter -port=33306 -db=wordpress -user=wordpress -pass=wordpress1234
-```
-
-You will see the metrics from those actions.
-
-# Grafana
-You can find a WordPress dashboard in $GOPATH/src/github.com/kotsis/wordress_exporter/wordpress_grafana.json
-
-For it to work you must define in Grafana a new Prometheus data source as prom1
-This must be the Prometheus instance that is scrapin metrics from wordpress_exporter.
-Then you can import the above json file and start viewing the metrics.
