1. Im having an issue with snmptraps in Librenms.
2. Im using Huawei equipment that generates Dying gasps on power failure. I want these traps in the event log but in a more human friendly format. I already set this up and it worked for a while but last few months it hasnt. Ive now set up a new blank Librenms to test but to no avail. I cant figure out where the problem is. Any suggestions based on the following?
3.  
4. Snmptrapd is working as expected. Logs confirum that i receive all traps, but seems there is something wrong with my handler.
5. My handler:
6. /opt/librenms/LibreNMS/Snmptrap/Handlers/HuaDG.php
7.  
8.  
9. <?php
10.  
11. namespace LibreNMS\Snmptrap\Handlers;
12.  
13. use App\Models\Device;
14. use LibreNMS\Interfaces\SnmptrapHandler;
15. use LibreNMS\Snmptrap\Trap;
16. use Log;
17.  
18. class HuaDG implements SnmptrapHandler
19. {
20.         public function handle(Device $device, Trap $trap)
21.         {
22.                 $dyinggasp = $trap->getOidData($trap->findOid('HUAWEI-BASE-TRAP-MIB::hwEntityDyingGasp'));
23.                 Log::event("Dying Gasp received", $device->device_id, 'trap', 5);
24.         }
25. }
26. ?>
27.  
28.  
29. Added the following to /opt/librenms/config/snmptraps.php:
30. 'HUAWEI-BASE-TRAP-MIB::hwEntityDyingGasp' => \LibreNMS\Snmptrap\Handlers\HuaDG::class,
31.  
32.  
33. /opt/librenms/logs/librenms.log shows the following:
34.  
35. production.ERROR: Call to undefined method Monolog\Logger::event() {"exception":"[object] (Error(code: 0): Call to undefined method Monolog\\Logger::event() at /opt/librenms/vendor/laravel/framework/src/Illuminate/Log/Logger.php:308)"}
36.  
37. Contents of that file line 308 is return "$this->logger->{$method}(...$parameters);".
38.  
39.     public function __call($method, $parameters)
40.     {
41.         return $this->logger->{$method}(...$parameters);
42.     }
43. }
44.  
45. Event is no longer a method?
