Мониторинг UPS APC и EATON на PHP

Мониторинг UPS APC и EATON на PHP

Не секрет, что ПО для мониторинга состояния UPS тяжеловесно и не бесплатно. Установка Zabbix только для этой задачи громоздка

Ниже представлен скрипт мониторинга APC и EATON, оснащенных сетевыми платами посредством SNMP.

Требуется установленный Apache и PHP с модулем php-snmp.

Отредактируйте массивы $urls для еатонов и $urls2 для APC, разрешите SNMP-1 public на чтение и настройте крон для отправки ежедневных писем.

На всякий случай оставляю тут протокол работы Smart APC.

Есть идея, сделать нештатную плату управления и мониторинга через COM с использованием ESP8266, так как платы управления недёшевы.

Используется специальный (с хитрым распаем) кабель.

Скорость соединения 2400.

Compare this to the nominal battery voltage

C

Internal temperature

036.0

Units are degrees C

D

Runtime calibration

!, then $

Runs until battery is below 25% (35% for Matrix)

This updates the j values - only works at 100% battery charge

Can be aborted with a second "D"

E

Automatic selftest intervals

336

Writable variable

Values:

  • 336 (14 days)

  • 168 (7 days)

  • ON (at power on) (note extra space)

  • OFF (never)

F

Line frequency, Hz

60.00

If this varies much, have a word with your local electrician

O

Writable variable

Values:

  • R (unacceptable utility voltage rate of change)

  • H (high utility voltage)

  • L (low utility voltage)

OK

Send twice with > 1.5s delay between chars

Older units may send "*" instead of "OK"

Also see grace period

L

Input line voltage

118.3

Does not necessarily read 000.0 on line failure

M

Maximum line voltage

118.9

This is the max voltage since the last time this query was run

N

Minimum line voltage

118.9

Like the one above, this one also resets itself on every query

Q

Status flags

UPS must receive command to enter smart mode continue communications after sending this

S

Soft shutdown

OK

Command executes after grace period

UPS goes online when power returns

Only works when on battery

U

Simulate power failure

!, then $

See async notifier section for info on ! and $

V

Tests battery, like pushing the test button on the front panel

Also see test results entry

X

SM

This must be sent before anything else on this page will work.

Also see turn dumb command to exit smart mode

Z

Shutdown immediately

n/a

Send twice with > 1.5s delay between chars

UPS switches the load off immediately (no grace period)

a

Protocol info

Returns three main sections:

Sections are separated with a period

b

c

UPS local id

UPS_IDEN

Writable variable

Up to 8 letter identifier for keeping track of your hardware

  • 02 = 25%

  • 03 = 90%

This prevents excessive cycling during multiple power failures

g

Nominal battery voltage

024

The battery voltage that’s expected to be present in the UPS normally

Compare to the actual voltage reading

042.4

Percentage

Only works on models with the Measure-UPS SmartSlot card

i

Measure-UPS: Dry contacts

00

  • 20 = contact 2

  • 40 = contact 3

  • 80 = contact 4

j

Estimated runtime

0

Writable variable

Values:

  • 0 = 5 second delay after power failure

  • T = 30 second delay

  • L = alarm at low battery only

  • N = alarm disabled

Does not affect low battery warning
