(Read more...)Recently I posted some speculation about where HP is going with their Comware and ProCurve networking lines. But what about the wireless gear? Where’s that going? As before, I have no inside information on this, and I’m just speculating based upon public information: Do your own research and thinking before making major purchasing decisions.
(Read more...)HP acquired 3Com in 2009. This added a large range of routing, switching and wireless networking to HP - but they already had existing ProCurve wired and wireless hardware. Clearly there’s overlap, so what’s the future of HP Networking? Where do they go with hardware and software? Here’s some speculation on my part.

HP has made some changes to the way Network Node Manager (NNMi) is licensed. These changes are a Good Thing, as they address two key pain points - license calculation, and access to extra features.
(Read more...)I have come to realise that I’ve tried to take part in too many communities, and it’s getting me down. Too many forums filled with too much noise, too many people not doing basic research. Too much time on my part to scroll through various RSS feeds & email lists. Time to re-evaluate what I’m doing, and why.
(Read more...)Recently I’ve been converting a network from an agent-based monitoring system to an agentless system. One challenge was handling custom application logfiles. Most agent-based monitoring systems make it very easy to add logfile encapsulators, to read a custom file, and react to specific patterns. But now I needed to convert the logfile into syslog, so it could be directed to my NMS, which would parse the syslogs, and raise alerts as required.
(Read more...)HP has been laying out their SDN vision over the last few months. They want to develop a complete SDN ecosystem, including an Open Standards-based network that can integrate with common overlay models, development resources to help 3rd parties to develop applications, test & validation tools, right through to an “App Store” that will deliver applications to end-users.
(Read more...)Network monitoring systems poll devices periodically, and then calculate average rates across the poll interval. Selecting the right polling interval is important - too frequently, and low-end devices can’t keep up. Too long an interval, and we might miss spikes, will lose detail, and will increase our time to detect & respond to incidents. We may choose to sample some specific values, or devices, more frequently - e.g. 1-minute status polling of our core devices, 5-minute polling for edge devices. But what about the collector - how does it decide when to run those polls?
