Senior System Administrator at Interactive Group
Monitoring solution provides comprehensive visibility across IT infrastructure
The good thing about Nagios Core is it covers everything. Everything in the IT domain, you can monitor anything. You can even monitor printers, the ports of printers, Core workstations, and storage. You can monitor the workflow Core and the utilization of computes. If you want to grasp everything of your IT equipment on a single interface, you can use Nagios. It's the best one. It provides dashboards, and you can also configure your emails and alerts with it. If something is critical, you can configure it to notify via emails. It has a very handy dashboard, providing live alerts and visibility for everything.

Network analytics have delivered lightweight, integrated visibility for search, observability, and security
Packetbeat analyzes specific protocols and is not suitable for full capture of all network traffic and network flows. I recall that Packetbeat can cover a limited number of protocols including ICMP, but not as deeply as other solutions. It covers NetFlows and these types of flows, but not at the level of a deep packet capture that you can find in the market where it taps every single packet in the network. Packetbeat is more about bringing statistics about the packets, but it doesn't capture these packets. The development intention of Packetbeat appears to be to provide a window for application monitoring and performance analytics, and for that purpose, it is doing sufficiently well. However, if the vendor has another goal to build a similar network monitoring solution that exists in the market, which is outside of Elastic's business nature, Packetbeat is a sensor that needs to be improved to the level of deep packet capture where it loses no packets in the network. That improvement would take Elastic to another level.

Questions from the Community

What is your experience regarding pricing and costs for Nagios Core?
Nagios Core is a free and open-source product. We don't charge for the product itself, but we charge for the man-hour costs related to installation, configuration, ongoing operation, and maintenance.
What needs improvement with Nagios Core?
The dashboard should be improved. It's very simple. I don't have a very clear or specific suggestion. You can change the skin of the dashboard, however, it's good for me.
What is your primary use case for Nagios Core?
I was a senior system administrator. I've been using Nagios Core for more than ten years now. It can be used to monitor hosts, such as machines, and monitor services of any kind. I'm using it to mo...
What is your experience regarding pricing and costs for Packetbeat?
Elastic is pretty cheap for large enterprises but unaffordable for small ones.
What needs improvement with Packetbeat?
I think that the scalability of the agent itself could be improved. It is also a bit limited in terms of capabilities. When a customer needs to customize the collection, I think it's tougher there.
What is your primary use case for Packetbeat?
I've been using Packetbeat ( /products/packetbeat-reviews ) for call centers, for logs, for observability, network monitoring, and some search engine optimization.
