Dangers Of Free Simple Network Management Protocol (SNMP) Software

You've probably looked at a lot of options for a Free SNMP Manager - varying widely in price and functionality. But you're not sure what you're looking for yet. Before you commit to an SNMP monitoring system, you need to make sure it supports essential telemetry functions. You need a list that can tell you what you need, and more importantly what free downloadable SNMP software can't give you.

Your Free SNMP Software Probably Doesn't Include These 8 Mission-Critical Features:

  1. Complete, Precise Alarm Descriptions

    A Free SNMP manager may not record location, time, severity and descriptions of alarm events. To adapt an off-the-shelf SNMP manager to monitor these factors, you must create and maintain a master alarm list representing all the monitored points in your network - and then also create and maintain a database associating all the Traps that may be sent to the SNMP manager (ex. SMARTS InCharge) with the alarms on that list.

  2. Identify Cleared Alarms

    Even more work is required to identify whether a Trap represents an alarm or a clear condition. Creating this addition to the Trap association database often requires analyzing multiple variable bindings within the Trap packet.

  3. Maintain a History of Standing Alarms

    A Free SNMP manager may not maintain a list of standing alarms. Instead, the typical SNMP manager maintains an event log of newly reported Traps and a history log of acknowledged Traps. As soon as a Trap is acknowledged, it is considered cleared. Imagine what might happen to your network if a system operator acknowledges an alarm, and then, for whatever reason, fails to correct the alarm condition. Who would know the alarm is still standing? Look for an SNMP Manager that gives you valuable and detailed alarms so that nothing is over looked.

  4. Sort or Filter Alarms

    Most free SNMP managers don't have built-in functions for organizing alarms by logical category, posting the same alarm to multiple logical categories, or sorting which alarms the user wants to see. Look for an SNMP Manager that allows you to filter nuisance alarms and other alarm-sorting features.

  5. Graphical Alarm Display on Geographic Maps and Photos

    Most free SNMP managers don't come with graphical alarm display capabilities that provide you with more visibility over your whole network in a clear and logical way. Simultaneously displaying all of your remote sites and equipment on an easy-to-read graphical interface is far more advanced than basic text alarm displays that are usually limited to one remote site at a time.

  6. Identify System Operators

    Free SNMP managers may not record the identity of the system operator who acknowledges an alarm. In the example of the negligent system operator, it would be impossible to determine who had made the mistake or to assign responsibility for the resulting problems. When looking for an SNMP manager, look for one that allows you to track which operator made the changes. This makes accountability for mistakes a lot easier to manage.

  7. Security for Multiple Users

    The typical SNMP manager is not designed for multi-user security. All Traps are posted to one alarm list; all users may view all alarms, and all users may acknowledge all alarms. That is, if they support multiple users in the first place. You don't want just anyone to be able to see your alarms. Look for a manager that allows you to set varying security levels for different users.

  8. Monitor Your Whole Network

    If you're like most companies, SNMP compromises only part of your network. What about your switches, sonnet rings, environmental alarm and legacy gear? A good manager should be able to monitor SNMP as well as all of your other mission-critical gear. Why use multiple systems for different monitoring, when you can use one system to keep track of everything?
