The Ravica Airflow Sensor is designed for systems that generate heat in the course of their operation and a steady flow of air is necessary to dissipate this generated heat.  System reliability and safety could be jeopardized if this cooling airflow stops.  Airflow Sensors monitor the circulation of air around critical equipment where a constant air-flow is required to maintain a consistent temperature and humidity status and reliable continual performance.

Airflow SensorThe Airflow Sensor is placed in the air stream path, allowing users to monitor the status of the flowing air.  This device measures the presence or absence of air flow, then the sensorProbe environmental monitor displays the measurement using a graphical display via its web interface.

NetFlow-Lite (NFlite) Exports Using the nProbe and a NetFlow Collector

This month’s Cisco Live show in London allowed for some great opportunities.  We mentioned that we met up with Luca Deri, developer of the nProbe.  Our friends at Plixer International also attended the show where Cisco demonstrated the abilities of their new Catalyst 4948E NetFlow-Lite (NFlite) exports using Plixer’s Scrutinizer NetFlow Analyzer with the nProbe.  NFlite is a sampling technology using NetFlow v9.

Plixer’s Product Manager, Michael Patterson, recently blogged about its features, explaining how the NFlite samples are sent to the nProbe, sending one sample per NetFlow datagram.  He also included a screen capture of their Scrutinizer NetFlow collector demonstrating the integrated view of NetFlow data from N7k and NetFlow-lite from the 4948E.

Latency using NetFlow from the nProbe- Part 2

December 20, 2010 by · Comment
Filed under: NetFlow probes 

As we discussed in our recent blog about the benefits of using a NetFlow probe, the nProbe is an open source network software application developed by Luca Deri which allows admins to get latency from flows on networks.  Through Luca’s partnership with Plixer International, Plixer has also been offering insight on how to get latency from network flows through their collector called Scrutinizer NetFlow Analyzer.

Latency from the nProbe comes in the following formats:

·       APPL_LATENCY  (Application Latency)
·       CLIENT_NW_DELAY  (Client Network Delay)
·       SERVER_NW_DELAY  (Server Network Delay)

Application Latency and Client Network Delay are determined when the NetFlow probe observes the TCP flags in a transaction.  Below we captured the TCP packets in a connection initiated by client (10.1.15.20) to web server (10.1.7.18).

Latency using NetFlow from the nProbe- Part 1

Determining the causes of application slowness has long been a study of both traffic volume and latency within the transaction.  Administrators had to determine if there was too much traffic on the connection which caused the slowness, or if there was sluggishness caused by the response time of an involved end system.  Perhaps it was even the application itself causing the slowness.

If you have an nProbe, you can get latency from network flows captured by the probe.  Read more
