ntopng – Display Multiple Metrics in One Graph

After my last ntopng trainings, which I taught as an instructor, I noticed that many ntopng users were not familiar with the display of multiple time series charts overlapping in one graphic.

Enable DNS Caching on RedHat 8

I was recently with a customer when he pointed out to me that his NetEye 4 system with its RedHat 8 operating system was sending an extremely large number of DNS queries to the DNS servers. After quickly analyzing the situation I found that RHEL does not cache DNS queries by default. Obviously the customer…

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…

The background to this is that the NetEye Master is located in Italy, which controls various satellites in other European and African countries. It’s therefore a strategic decision that alarms are sent from…
