InfluxDB is the database used in NetEye for saving performance data. It guarantees graphic visibility of the data (thanks to the Grafana frontend) and it is very important that the data stored is useful. I’ll give you an example of how simple it can be to produce obsolete data in Influx: Suppose I create a…
Read MoreWhen designing complex systems with a multitude of services, more often than not some of them logically form loosely coupled units. Usually these services should remain independent to a degree, i.e. free to be started or stopped independently. However, we also wanted a mechanism to command the loosely coupled unit as a whole. Sometimes however…

Read MoreWith SIEM we ensure maximum security in the management of sensitive data Even the safest bulwarks require permeable zones. The same applies to the security systems we use to protect our data from unauthorized access. But every system, no matter how meticulously monitored, contains security gaps. When these become known, it is the task of…
Read MoreIn the previous blog post in our #devops series, we discussed how to automatically provision a NetEye cluster with virtually zero hassle. Thanks to Ansible, in fact, we dramatically reduced the amount of manual effort needed to generate a fully working cluster. This, in turn, opened up an opportunity to boost our cluster testing infrastructure…
Read MoreA common issue in cluster environment is the split brain condition. A split brain occurs when some nodes of the cluster are not able to communicate properly, but instead continue to work like two separate, distinct clusters leading to data or service inconsistency. To prevent this situation a common solution is to introduce the concept…
Read MoreUse case : I want to send a PDF with services problems by email. Let’s suppose a client wants to receive an email containing a file with a list of all service problems. Unfortunately, the SLM module doesn’t have the ability to specify the filter service_state on the object field, so I modified the export_csv_export.php…
