TECHNICAL DATA

Trends and
thresholds

ENA eases the burden of managing large networks with powerful trending and dynamic threshold functionality.

Trend lines show the local shape of your data, and help you identify long-term upwards and downwards movements in series data. Because ENA has been designed to suit the way you work and manage your network, you can set a trend on any chart at any time.

    Set trends when
    creating a chart

    Create charts with trends based on the series data for the previous 2, 4, 8 or 16 weeks. Complement this information by adding a prediction in the legend that forecasts the future value of the series at a specified date.

    Set trends as you
    navigate your network

    As you navigate around your network in the ENA UI, set a 4-week trend to any existing series data chart (on both system and custom dashboards), anywhere across the UI, for immediate insight into that series’ long-term behavior.

    Apply trends to enhance
    network management

    Capacity planning

    Plan for network growth based on a range of trending data, and understand how the changes you make will affect network utilization.

    Anticipate network traffic

    Proactively provision for changes in CPU, port and memory utilization, using all available data from a specified period to display underlying patterns all whilst removing the noise. 

    Identifty network problems

    Use trend lines to detect issues and outliers based on abnormal behavior, e.g. when studying fault discards or SurePath path latency. This gives you a faster and more accurate idea of where the problems lie than if you were to simply use manual thresholds that require regular observation and tweaking.

    DYNAMIC THRESHOLDS

    MANAGE ALERTS ON A
    VOLATILE NETWORK

     

    You might manage hundreds of devices and objects on your network, all producing data necessary for creating accurate and appropriate insight into the workings of your network, but at volumes far beyond the ability of humans to monitor. ENA helps you efficiently organize this data into meaningful and actionable events and incidents.

    Static and dynamic thresholding is one part of this toolset, enabling you to prevent events and incidents being raised in unnecessary circumstances unless those thresholds are exceeded.

    Static thresholds

    You can enable static thresholds that, when crossed, cause ENA to raise events. These can be set against the following:

    • an individual event.
    • a managed device/object or View.
    • all objects on an Entuity server.

    Dynamic thresholds

    Dynamic thresholds bring greater agility to thresholding, and allow you to configure thresholds so that alerts are raised upon deviations from previous normal behavior across a time period.

    This means that even when you know that device behavior changes within acceptable restrictions over time, you can still maintain a dynamic threshold on attributes that reflect this, saving you the effort of manually altering your thresholds across potentially hundreds of devices.

    Normal behavior (known as the baseline) is established for a given attribute on a given port by maintaining the last 4 weeks’ worth of polled data, and then applying an averaging algorithm.

    You then specify a tolerance against the baseline, representing the dynamic threshold over which an event can be raised.

    For example, if the historical baseline of an attribute is 10, and you set a tolerance of 20, then the dynamic threshold at which ENA will raise an event is 30.

    CAPACITY REPORTING

    SEE WHERE INCREASING
    TRAFFIC IMPACTS SERVICE

    In an always-on world, customer requirements and SLAs place ever greater demands on your network. This makes capacity management a crucial part of network management and essential to business success. Planning for growth and expansion can mean the difference between hitting a ceiling and taking your business to the next level.

    Capacity Planning Reports

    Take advantage of ENA’s comprehensive capacity planning reports to identify areas in your network where increasing load may impact service delivery. Planning reports come in two forms: heat map reports and trend reports.

    The reports are based on customizable critical (red) and warning (yellow) thresholds, so that you can immediately spot where problems are arising.

    Planning Heat Map reports

    These reports give you a time vs date colored heat map of CPU utilization, memory utilization, bandwidth utilization or port discards, based on customizable critical (red) and warning (yellow) thresholds, so that you can immediately spot the red and yellow zones indicating when and where capacity problems are arising.

    Device Memory Capacity Planning Heat Map report

    Port Bandwidth Capacity Planning Heat Map report

    Port Discards Capacity Planning Heat Map report

    Planning Trend reports

    These reports provide a device vs metric colored table for CPU utilization, memory utilization, bandwidth utilization or port discards over a specified time period. These reports measure against mean inbound, outbound, percentile and 6 month projection metrics. Red and yellow warnings notify you about the devices and ports that face capacity issues.
