Data Capture & Analytics

MetaWatch is a powerful application designed for Metamako's high performance K-Series devices which simplifies network data capture, monitoring and analytics.

It combines several components of a traditional network monitoring solution into one powerful device:

  • Tapping
  • Tap Aggregation
  • Precise Time Synchronisation
  • Nanosecond-resolution Timestamping
  • Deep Buffering


MetaWatch provides all of these features with virtually no impact on the monitored network performance, and enabling a seamless stream of timestamped frames to storage and analytics tools. MetaWatch is a pre-packaged, qualified, calibrated solution, giving customers confidence that they are capturing and timestamping all data on the network. MetaWatch replaces: 

  • 30 passive optical taps;
  • an aggregation and timestamping switch;
  • media converters, patch panels, and all other Layer 1 switch use cases.

MetaWatch is available on Metamako K-Series devices which have an embedded Xilinx Virtex 7 FPGA. Download the datasheet >

Deep Buffering

Dependable capture

Data flow is unpredictable, and relentless. Spikes in network traffic result in microbursts or longer peaks which are a perennial problem for most packet brokers or aggregation switches which, by their very design, are deliberately over-subscribed. Available buffer capacity can easily be overwhelmed, resulting in lost packets.

MetaWatch brings an aggregated 300Gbps ingress down to a 20 Gpbs (2x10GbE) egress rate. Incoming frames are buffered in up to 32GB of memory within the device before being aggregated and delivered to downstream capture devices. Moreover, MetaWatch implements industry-standard IEEE flow control on egress ports, allowing congested downstream capture appliances to leverage the deep buffering available and "push back" rather than drop frames thus regulating the rate at which frames are delivered to them. 

The MetaWatch application contains two 15:1 buffered, aggregated port group instances:

Deep Buffering


Benefits of MetaWatch deep buffering: 

  • absorb microbursts and over-subscription over an extended period;
  • allow downstream capture devices to mitigate packet loss when they are
  • increase over-subscription, reducing the number of expensive downstream capture ports
  • significantly reduce the probability of dropped frames
  • no need to continuously upgrade capture or analytics platforms to match growing data traffic demands.

Precision Timestamping

Dependable timing

Timing is critical in today's financial, cloud, security and HPC monitoring systems. It is important to be able to measure significant events as accurately as possible. MetaWatch's true 1ns timestamp resolution offers the best solution.

To give an example, timing and time synchronisation has been recognised as key to financial market transparency by regulators - be it in regards to the European MiFID II regulations or the US equivalent expected to move to similarly strict rules. ( >> Download our "MiFID II - Timestamping" Brief)

Nanoseconds are the difference between success and failure and understanding the timing of events in trading systems is critical to success. 
Optional high-stability oven-controlled Oscillator (OXCO) or Rubidium (Rb) atomic clock modules are available as an upgrade providing improvements in oscillator accuracy and holdover stability.
