Versions:
Packetbeat 9.3.2, the eighteenth release from Elastic’s Beats family, is a lightweight, open-source network packet analyzer engineered for real-time, distributed visibility into traffic flowing across modern infrastructures. Positioned in the Network Monitoring category, the agent passively sniffs packets on selected interfaces, decodes Layer-7 protocols—including HTTP, HTTPS-TLS metadata, MySQL, PostgreSQL, Redis, MongoDB, Cassandra, Thrift and others—on the fly, and reassembles individual messages into time-correlated transactions. Each parsed transaction is converted into a structured JSON document that is shipped directly to Elasticsearch, where it is indexed and made available for search, aggregation and alerting; accompanying Kibana dashboards provide immediate, click-through access to top-talkers, response-time percentiles, error rates and flow volumes without manual packet dissection. Typical use-cases span DevOps teams troubleshooting micro-service latency, security engineers hunting anomalous lateral movement, SREs validating TLS cipher strength, and operators who need service-level maps automatically generated from live traffic. Because Packetbeat integrates seamlessly with the larger Elastic Stack, users can pivot from a slow SQL query to host logs to cloud metrics in a single pane, or feed the data to Elastic Machine Learning to baseline throughput and surface rare processes. Configuration is YAML-driven, supports BPF filters, GeoIP enrichment, Kubernetes autodiscovery, and cloud-vendor metadata, while policy-centralization through Fleet enables zero-touch rollouts to thousands of nodes. The software is available for free on get.nero.com, with downloads provided via trusted Windows package sources (e.g. winget), always delivering the latest version, and supporting batch installation of multiple applications.
