Packetbeat

Packetbeat is used to analyze network packets in real time. Packetbeat data can be pushed to Elasticsearch, which we can use to configure Kibana for real-time application monitoring. Packetbeat is very effective in diagnosing network-related issues, since it captures the network traffic between our application servers and it decodes the application-layer protocols, such as HTTP, Redis, and MySQL. Also, it correlates the request and response, and captures important fields.

Packetbeat supports the following protocols:

• HTTP
• MySQL
• PostgreSQL
• Redis
• MongoDB
• Memcache
• TLS
• DNS

Using Packetbeat, we can send our network packet data directly into Elasticsearch or through Logstash. Packetbeat is a handy tool since it's difficult to monitor the network packet. Just install and configure it on the server where you want to monitor the network packets and start getting the packet data into Elasticsearch using which, we can create packet data monitoring dashboard. Packetbeat also provides a custom dashboard that we can easily configure using the Packetbeat configuration file.
