During the course of a NetEye installation, a wide range of performance data is collected. From latency metrics of ping checks, to the saturation data of disks and memory units, to the collection of utilization metrics of various kinds. For all of this data we’ve adopted the open source time series database InfluxDB. The time-aligned…

How to Drop a Tag in InfluxDB

If  you’ve ever had cardinality problems with InfluxDB, you might have discovered that a tag is the likely culprit.  Well done!  But now your next step is getting rid of that tag, and that’s when you’ll realize that in a time series database, tags play an important role in indexing.  Because dropping tags is rather complicated,…

Into the Flows: Collecting Data with nProbe and nTop

The role of these two components is pretty clear: nProbe has the role of collecting traffic data, while nTop makes that data visible and easily analyzable. There is something, however, that needs to be explicitly stated, which is to decide whether it’s ntopng that should contact nProbe or vice versa, and as we’re in a…

Grafana for nTop: Realizing a Dashboard

A customer with a NetEye installation to which I had added the nTop module asked me if I could integrate nTop’s Grafana Dashboards, so they could view them by consulting NetEye’s ITOA Menu. The installation and configuration of nTop for this client, a task I had already conducted some time ago, was a matter of…

Performance Metrics Collection from NetEye to Elastic

Today my objective is to collect the performance metrics from various NetEye Icinga checks and write them out to Elasticsearch so I can apply Machine Learning (ML) algorithms to identify potential anomalies. This is a task that’s not possible with the open-source version of InfluxDB installed in NetEye. Moreover, this data in Elastic is used…
