OpenTSDB + Grafana

This setup requires OpenTSDB, which in turn requires Hbase, and Grafana. Instructions provided are for a Debian-based system.

OpenTSDB + Hbase

First, set up Hbase according to https://hbase.apache.org/book.html#quickstart

Start it with

JAVA_HOME=/usr ./bin/start-hbase.sh

Then, get an OpenTSDB release from https://github.com/OpenTSDB/opentsdb/releases

Create the necessary tables via e.g.

env COMPRESSION=NONE HBASE_HOME=/home/hendriksl/hbase-1.2.6 /usr/share/opentsdb/tools/create_table.sh

and start the opentsdb service.

Grafana

Get the latest release from http://docs.grafana.org/installation/debian/ , install and start the grafana-server service.

Cronjob to insert new datapoints from collected flow data

The script called fbit_to_rrd.py updates both the RRD files as well as the opentsdb database. An example cronjob to update every 5 minutes:

2,7,12,17,22,27,32,37,42,47,52,57 * * * * cd /home/hendriksl/ipfix-rrd && python3 /home/hendriksl/ipfix-rrd/fbit_to_rrd.py auto > /dev/null

Connect Grafana and OpenTSDB

In the Grafana web-interface, click on the Grafana logo in the upper left corner and choose 'Data sources' from the dropdown menu. Click 'Add data source'. Set 'Type' to 'OpenTSDB' and configure the URL to be http://localhost:4242 and set 'Access' to 'Proxy'. Further configuration might depend on specific versions of OpenTSDB used.

Now, new dashboards with custom plots can be created via 'Dashboards' in the dropdown menu, where the datapoints from the OpenTSDB database should appear when defining a new graph.

Web ui

  • activate venv
  • FLASK_APP=main.py flask run

Update RRD files via cron

2,7,12,17,22,27,32,37,42,47,52,57 * * * * cd /home/hendriksl/ipfix-rrd && python3 /home/hendriksl/ipfix-rrd/fbit_to_rrd.py auto > /dev/null
