Packet Capture Export

Simple, Powerful Packet Capture And Retrieval

Network, IT operations and security teams need fast access to packet captures on-demand. These teams need a quick and intuitive GUI that requires no training or support but enables multiple different uses of packet captures.

Corvil appliances store packets after processing to deliver real time business, application, security and infrastructure analytics. The stored packets are retrieved with a simple GUI with filtering options and syntax familiar to network, IT operations and security teams.

Corvil’s simple GUI means people can get the packets they need quickly and easily without becoming product experts.

Corvil Capture - Packet Capture Export

Corvil Appliances

Our range of appliances offer reliable glitch-free packet capture with many additional capabilities, including:

  • Guaranteed high-rate capture to disk with accurate hardware time stamping for up to 40G traffic rates
  • Deep buffering which lowers capital costs while ensuring peak rate capture
  • Maximized use of onboard storage with real- time data compression
  • Support for sub-microsecond synchronization to external sources using Pulse Per Second (PPS) and Precision Time Protocol (PTPv2 / IEEE 1588).
  • Detection of missing TCP data which speeds identification of packet loss issues upstream of the Corvil appliance and ensures you have high quality data.

Corvil also enables you to leverage existing investments in aggregation infrastructure leveraging our remote data streaming feature. We support for all network packet brokers (NPB) port tagging and time- stamping capabilities, including Apcon, Arista, Cisco, cPacket, Gigamon, Ixia, Netscout and VSS.

Packet Capture Export

When you need immediate access to captures, the Packet Capture Export screen provides a simple yet powerful interface. Select a time period, optionally choose physical ports and filtering, and press the export button to download pcap to your desktop. Optionally filter the packets with a familiar syntax:

  • Berkeley Packet Filtering (BPF)
  • Wireshark™ syntax
  • Corvil filtering extensions, such as filtering on upstream network packet broker ports.

Power Users

For power users, a command-line interface provides access to all export and filtering options. The CLI also provides access to the industry-standard tshark utility to assist in troubleshooting and targeted export, for example:

  • Identify all HTTP traffic with TCP zero-window alerts
  • Identify top-conversations before doing a filtered export

API Support

Corvil Capture offers comprehensive APIs access to retrieve stored packet data such as:

  • PCAP files, with support for all the filtering available at the GUI
  • A text file of packet headers
  • A timeseries of microburst for all traffic to a particular host
