![17 - 1Wireless Controller and Service Platform System Reference Guide17WiNG EventsWiNG outputs an event message for configuration changes and status updates to enable an administrator to assess the success or failure of specific configuration activities. Use the information in this chapter to review system generated event messages and their descriptions. Each listed event can have customized notification settings defined and saved as part of an event policy. Thus, policies can be configured and administrated in respect to specific sets of client association, authentication/encryption and performance events. Once policies are defined, they can be mapped to device profiles strategically as the likelihood of an event applies to particular devices. By default, there's no enabled event policy and one needs to be created and implemented.For more information on the UI’s descriptions of events, refer to Fault Management on page 13-1.17.1 Event MessagesTo review event history messages:1Select Configuration > Diagnostics > Fault Management > Event History to display the Event History screen.2Select Fetch Historical Events to display the diagnostic events in the Event History table.3 Refer to the following (read only) information to assess logged diagnostic events.ADOPT-SERVICESNMP_SUCCESS6 SNMP framework successADOPT-SERVICESNMP_FAILURE6 SNMP framework failureADOPT-SERVICETUT_TEMPERATURE_ALARM_RAISED ([str])Temperature alarm raised on sensorADOPT-SERVICETUT_TEMPERATURE_ALARM_CLEARED([str])Temperature alarm cleared on sensorADOPT-SERVICETUT_TEMPERATURE_ALARM_CLEARED([str])Temperature alarm cleared on sensorADOPT-SERVICETUT_FAN_ALARM_CLEARED5IPX ([str])Fan alarm cleared on IDADOPT-SERVICETUT_PWRCTRL_ALARM_RAISED5IPX ([str])Power controller alarm raisedADOPT-SERVICETUT_PWRCTRL_ALARM_CLEARED5IPX ([str])Power controller alarm clearedADOPT-SERVICETUT_LINE_POWER_ALARM_RAISED5IPX ([str]) Line power alarm raised on id [str]Line power alarm raisedADOPT-SERVICETUT_LINE_POWER_ALARM_CLEARED5IPX ([str]) Line power alarm cleared on id [str]Line power alarm cleared ADOPT-SERVICETUT_WLAN_CLIENT_ASSOC6IPX ([str]) Client [str] on interface index [str] associatedClient associated](https://usermanual.wiki/Extreme-Networks/AP3917E.WiNG-5-9-1-System-Reference-Guide-Part-4/User-Guide-3831160-Page-7.png)

![PUBLICLY AVAILABLE SOFTWAREAccess Point, Wireless Controller, and Service Platform System Reference Guide A - 31[This is the first released version of the Lesser GPL. It also counts as the successor of the GNU Library Public License, version 2, hence the version number 2.1.]PreambleThe licenses for most software are designed to take away yourfreedom to share and change it. By contrast, the GNU General Public Licenses are intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users.This license, the Lesser General Public License, applies to some specially designated software packages--typically libraries--of the Free Software Foundation and other authors who decide to use it. You can use it too, but we suggest you first think carefully about whether this license or the ordinary General Public License is the better strategy to use in any particular case, based on the explanations below.When we speak of free software, we are referring to freedom of use, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish); that you receive source code or can get it if you want it; that you can change the software and use pieces of it in new free programs; and that you are informed that you can do these things.To protect your rights, we need to make restrictions that forbid distributors to deny you these rights or to ask you to surrender these rights. These restrictions translate to certain responsibilities for you if you distribute copies of the library or if you modify it. For example, if you distribute copies of the library, whether gratis or for a fee, you must give the recipients all the rights that we gave you. You must make sure that they, too, receive or can get the source code. If you link other code with the library, you must provide complete object files to the recipients, so that they can relink them with the library after making changes to the library and recompiling it. And you must show them these terms so they know their rights.We protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you this license, which gives you legal permission to copy, distribute and/or modify the library.To protect each distributor, we want to make it very clear that there is no warranty for the free library. Also, if the library is modified by someone else and passed on, the recipients should know that what they have is not the original version, so that the original author's reputation will not be affected by problems that might be introduced by others.Finally, software patents pose a constant threat to the existence of any free program. We wish to make sure that a company cannot effectively restrict the users of a free program by obtaining a restrictive license from a patent holder. Therefore, we insist that any patent license obtained for a version of the library must be consistent with the full freedom of use specified in this license.Most GNU software, including some libraries, is covered by the ordinary GNU General Public License. This license, the GNU Lesser General Public License, applies to certain designated libraries, and is quite different from the ordinary General Public License. We use this license for certain libraries in order to permit linking those libraries into non-free programs.When a program is linked with a library, whether statically or using a shared library, the combination of the two is legally speaking a combined work, a derivative of the original library. The ordinary General Public License therefore permits such linking only if the entire combination fits its criteria of freedom. The Lesser General Public License permits more lax criteria for linking other code with the library.](https://usermanual.wiki/Extreme-Networks/AP3917E.WiNG-5-9-1-System-Reference-Guide-Part-4/User-Guide-3831160-Page-54.png)
