Install the package.
After that you can Enable and start the
grafana service and access the application on localhost, e.g.: http://127.0.0.1:3000 . The default username is
admin and password
admin to access the web frontend.
*:3000so make sure to change the configuration or enable the relevant firewall rules.
In case of scaleable server monitoring in combination with Grafana and InfluxDB, one could choose software like collectd or statsd. More generally any measurement data can be aggregated with InfluxDB and displayed with Grafana. There are modules and libraries for several programming languages to interact with InfluxDB and one could even store data with a simple http post command using the program curl.
Herefore, create a database named
curl -G http://localhost:8086/query --data-urlencode "q=CREATE DATABASE example"
Post data into the example database:
curl -i -XPOST 'http://localhost:8086/write?db=example' --data-binary 'cpu_load_short,host=server01,region=us-west value=0.64 1434055562000000000'
Creating Grafana dashboard
- Before creating a dashboard, we have to add a data source. So first click on
Data sourcesin the left menu and then on
- Name can be something like
influxdband the type should be set to
InfluxDB 0.9. In this example, the url for the Http settings is
http://localhost:8086. Note that the port is not the same as the one of the web interface! Database name corresponds to the one earlier choosen, e.g.
example. If not changed, username and password are
- Click on
Test connectionto see everything is working and then on
- Next, back at the front page, click
Homein the left-upper corner and then on
- Now this might be a bit counter-intuitive, but to add a new dashboard you have to hover and click over the little green box on the left side and then, for example, choose:
- Click on the title of the new graph and select
- In the graph settings in
influxdbas data source in the lower-right corner.
- Create a query by selecting your aggregated data. Click on
select measurementwhich is located beside
FROM. In the dropdown menu should appear a list of "tables" in your database, e.g. the table named
localhost. If no suggestions comes up, your connection to InfluxDB might be broken or no data has been aggregated yet.
- Beside the bold text

- To save changes, click
Back to dashboard, then the floppy disc icon.
