[Devices]: iRZ-RL01x - сбор информации по SNMP
Задача:
Такая же как в предыдущей заметке о iRZ RUH2x , только с использованием новой серии оборудования, указанной в теме.
Само устроство - это роутер с процессором MIPS, mini-PCIE радио-модулем QUECTEL EC20 и прошивкой Openwrt 15.05.1 с набором различных скриптов от производителя.
Скорее всего радио-модуль, установленный в устройство может отличаться от того, что используется в моем случае.

Quectel
EC20
Revision: EC20EQAR02A12E2G
Данная серия устройств уже может полноценно отдавать уровень GSM-сигнала и прочие нужные нам параметры по SNMP, т.е. фактически реализована поддержка скриптов в snmpd.
root@3gr0:~# opkg list-installed | grep snmp
irz-snmp-scripts - 1.0.0-1
libnetsnmp - 5.4.4-1
snmpd - 5.4.4-1
Этими скриптами я и постарался максимально воспользоваться для написания своих утилит, позволяющих единообразно собирать статистику работы совместно с устройствами серии iRZ RUH2x.
Для начала из /usr/libexec/snmp/irz-mobile-snmp.sh выбираем нужные функции, исключая код поиска ОID и помещаем в файл, который будем подключать в собственных скриптах.
