Network Telemetry in LMOS 7.2.53 provides the traffic visibility you need to stay on top of network events.
Today, Kemp is excited to announce the introduction of Network Telemetry with Load Balancing as a key feature in the LoadMaster product family.
As a Product Manager at Kemp, I hear from LoadMaster customers about the things that keep them up at night. Like application performance and security. Application providers want to be able to understand how their clients experience the services they offer through LoadMaster and be able to assess that experience across complex network configurations.
LoadMaster has a central role in providing a positive application experience for clients accessing the applications hosted behind it. While LoadMaster offers traditional telemetry tools like access to system information via SNMP (the Simple Network Management Protocol) and packet captures taken by the Loadmaster. Some customers have requested the ability to export the entire application traffic stream via one of its network ports for central collection and analysis.
With the addition of Network Telemetry via the Flowmon Probe on LoadMaster, Kemp now makes available to its LoadMaster customers the power of the Flowmon Probe and Collector to fill this need.
LoadMaster + Flowmon = Powerful Modern Network Telemetry
Network Telemetry is statistical data generated from analysis of the traffic in your network. Many of us are already familiar with the network data we can access via facilities. These include SNMP (Simple Network Management Protocol) and packet capture tools (like WireShark). Leveraging both can give you a lot of detailed information about your network.
The problems come with the “a lot” and “detailed” bits of that statement above. Analyzing all that detailed data is time-consuming and requires lots of data storage. Modern network telemetry data, on the other hand, is generated based on the underlying data transfers abstracted from packets. The subject of the communication itself as distilled from the traffic (packet payloads are not stored). These statistics represent the flow data in the network, which can be thought of like a list of telephone calls. From this we can gain an understanding of who communicates with whom, when, how long, and how often.
The Flowmon Probe on LoadMaster examines the traffic flowing through LoadMaster and extracts data such as IP addresses, data volumes, time, ports, and protocols. Along with latency measurements and application layer data for a variety of protocols.
When a request from a client to the server, the probe looks into the packet header and creates a flow record.The flow record contains information about the source & destination IP addresses and ports, protocol number, number of bytes and packets, and all other information from layer 3 and 4. Individual data network communications are identified by source & destination IP addresses, ports, and protocol number.
When the server responds to the client, IP addresses and ports in the packet header are reversed and another flow record is created. Subsequent packets with the same attributes update the previously created flow records (e.g.: number of bytes, duration of communication). When the communication is over, flow records are then exported for further analysis.
LoadMaster Network Telemetry improves both your visibility into network performance and security as well as your ability to respond to customer needs and security issues before they become a problem. This applies whether you have a network telemetry appliance on your network already or not:
The Flowmon Collector, as shown above, can be completely customized to reflect your LoadMaster application estate. Combined dashboards that describe the overall traffic flow through LoadMaster as well as Virtual Service specific dashboards that focus on specific applications. Collector opens up an entirely new dimension of actionable insights:
