SNMP error: (noSuchName) There is no such variable name in this MIB.
Иногда, в Zabbix можно увидеть ошибку "SNMP error: (noSuchName) There is no such variable name in this MIB.", обычно на discovery правилах. Проблема связана с тем, что по-умолчанию Zabbix использует bulk-зарпосы, которые не всегда работают для некоторых устройств. Чтобы избежать этой ошибки, достаточно в настройках интерфейса SNMP в Zabbix у хоста снять галочку с ``Use bulk requests'.
