Alert checkers are not Working in 21.10.11633

A regression bug managed to make it into the CE release which prevents device_id being correctly set.

You can fix it by making a small change in includes/alerts.inc.php. Remove the /* */ lines around the code setting `devices`.`device_id` as `device_id` around line 2864:

	2864		/* hrm, already join with using
	2865	2869	if ($entity_type !== 'device') {     $sql .= ", `devices`.`device_id` as `device_id`";   }
	2868		*/

 Otherwise there'll be a new CE in a day or so.

Please make and attach additional information about the device:

• full snmp dump from device:

  snmpwalk -v2c -c <community> -t 3 -Cc --hexOutputLength=0 -ObentxU <hostname> .1 > myagent.snmpwalk

  snmpwalk -v2c -c <community> -t 3 -Cc --hexOutputLength=0 -ObentxU <hostname> .1.3.6.1.4.1 >> myagent.snmpwalk

  If device not support SNMP version 2c, replace -v2c with -v1.

• If you have problems with discovery or poller processes, please do and attach these debugs:

  ./discovery.php -d -h <device>

  ./poller.php -d -h <device>

• additionally attach device and/or vendor specific MIB files
