Trending and baselining bring automation and proactive prediction that most other techniques miss. Using highly granular baselines (15 minutes or under) over predictable business intervals (seasons, months, weeks) can allow us to quickly spot deviations from norm before they affect the performance of applications and the quality of the user experience. Trending, on the other hand, lets us predict what may lie in the future, based on granular historical data. Generally, in order to have a meaningful prediction, a significant amount of historical data should be available-about six times the length of the interval we are trying to predict (e.g., for a one-month prediction, we need about six months of historical data). This data must be granular (preferably raw/non-aggregated) so that the statistical analysis can be as sophisticated as possible-accounting for peaks, valleys and repeating patterns.
Managing bandwidth needs and consumption is a discipline that has existed since the first 150bps modems connected computer systems together. Today, with multi-gigabit links becoming an everyday reality, we are still facing the same conundrums. Only the number of zeros has changed.
Vess Bakalov, CTO for SevOne Inc., says one thing to remember is that bandwidth and bandwidth management is a means to an end, and not an end in itself. We need adequate performance for our applications and users for the minimum expenditure. To do this effectively, we must first understand what “adequate” means for these users and applications. Only once this often-omitted step is completed can we effectively employ any bandwidth management techniques.
Check out this list of five quick tips on better bandwidth management.
SevOne provides a fast, easy, and scalable network appliance that combines granular performance data from NetFlow, SNMP, VoIP, IP SLA, NBAR and WMI into a single view. This enables IT staff to lower their total cost of ownership, assure service levels and increase productivity.
