本次將利用QNAP上安裝並執行DOCKER後，利用ubuntu增加NUT服務，並在IFTTT上建立applet觸發TELEGRAM告警。
NUT部分安裝在Docker上面，Docker相關設定請自行google或是參考本篇，我安裝的是ubuntu 18.04
安裝NUT
apt-get install nut
設定
編輯nut.conf
vi /etc/nut/nut.conf
修改mode為netclient
# Since this MODE is opened to the network, a special care should be applied # to security concerns. # - netclient: this mode only requires upsmon. # # IMPORTANT NOTE: # This file is intended to be sourced by shell scripts. # You MUST NOT use spaces around the equal sign! #MODE=none MODE=netclient
編輯upsmon.conf
vi /etc/nut/upsmon.conf
修改以下資訊，以便連結QNAP的UPS。
...以上略 # password = blah # upsmon master (or slave) # # "master" means this system will shutdown last, allowing the slaves # time to shutdown first. # # "slave" means this system shuts down immediately when power goes critical. # # Examples: # # MONITOR myups@bigserver 1 monmaster blah master # MONITOR su700@server.example.com 1 upsmon secretpass slave # MONITOR myups@localhost 1 upsmon pass master (or slave) MONITOR qnapups@192.168.1.1 1 admin 123456 slave # -------------------------------------------------------------------------- # MINSUPPLIES <num> # # Give the number of power supplies that must be receiving power to keep # this system running. Most systems have one power supply, so you would # put "1" in this field. # # Large/expensive server type systems usually have more, and can run with # a few missing. The HP NetServer LH4 can run with 2 out of 4, for example, # so you'd set that to 2. The idea is to keep the box running as long # as possible, right? ....以下略
可以試著啟動看看
service nut-client restart
如果出現Communications with UPS qnapups@192.168.1.1 lost 或是 UPS qnapups@192.168.1.1 is unavailable 則表示你沒有把IP設定在QNAP的UPS通知列表內。
設定成功會出現以下訊息
Broadcast message from user (somewhere) (Fri Apr 10 21:33:33 20 Communications with UPS qnapups@192.168.1.1 established
可以使用 upsc 來擷取UPS的訊息
upsc qnapups@192.168.1.1

接下來設定upsmon.conf
vi /etc/nut/upsmon.conf
...前略 # RUN_AS_USER <userid> RUN_AS_USER nut ...中略... # NOTIFYCMD <command> NOTIFYCMD /sbin/upssched ...中略... # NOTIFYFLAG - change behavior of upsmon when NOTIFY events occur NOTIFYFLAG ONLINE SYSLOG+WALL+EXEC NOTIFYFLAG ONBATT SYSLOG+WALL+EXEC NOTIFYFLAG LOWBATT SYSLOG+WALL+EXEC NOTIFYFLAG FSD SYSLOG+WALL+EXEC # NOTIFYFLAG COMMOK SYSLOG+WALL # NOTIFYFLAG COMMBAD SYSLOG+WALL NOTIFYFLAG SHUTDOWN SYSLOG+WALL+EXEC NOTIFYFLAG REPLBATT SYSLOG+WALL+EXEC # NOTIFYFLAG NOCOMM SYSLOG+WALL # NOTIFYFLAG NOPARENT SYSLOG+WALL ...後略
與 upssched.conf
vi /etc/nut/upssched.conf
...前略 # CMDSCRIPT <scriptname> CMDSCRIPT /var/ups/upsifttt.sh ...中略... # PIPEFN <filename> PIPEFN /var/run/nut/upssched/upssched.pipe ...中略... # LOCKFN <filename> LOCKFN /var/run/nut/upssched/upssched.lock ...中略... # - EXECUTE <command> AT ONLINE * EXECUTE ups-back-on-line AT ONBATT * EXECUTE ups-on-batt AT LOWBATT * EXECUTE ups-lo-batt AT SHUTDOWN * EXECUTE ups-shutdown AT REPLBATT * EXECUTE ups-batt-fail AT FSD * EXECUTE ups-fsd
在EXECUTE的command可以自由命名。
IFTTT
申請IFTTT webhook applet ( if Webhook then IFTTT )
建立新的applet
選Webhooks，並設定Event Name，我設定為NUT。
再選一個Telegram action，並設定action的Message text。
其中的參數可以自行搭配使用，因為需要的不多，我只用了OccurredAt與Value1。
整體是這樣
然後你的Telegram必須加入@IFTTT這個機器人
完成後回到ubuntu執行命令，複製範例到CMDSCRIPT所定位置
rsync -a /bin/upssched-cmd /var/ups/upsifttt.sh
編輯CMDSCRIPT
vi /var/ups/upsifttt.sh
#! /bin/sh
#
# This script should be called by upssched via the CMDSCRIPT directive.
#
# Here is a quick example to show how to handle a bunch of possible
# timer names with the help of the case structure.
#
# This script may be replaced with another program without harm.
#
# The first argument passed to your CMDSCRIPT is the name of the timer
# from your AT lines.
event_name='你的webhooks event name'
webhook_key='你的webhooks key'
msg=''
case $1 in

esac
if [ "$msg" != "" ]
then
curl -l --data-urlencode "value1=${msg}" "https://maker.ifttt.com/trigger/${event_name}/with/key/${webhook_key}"
else
echo "NOMESSAGE \r"
fi完成後將upsifttt.sh +x
chmod a+x /var/ups/upsifttt.sh
測試，出現Congratulations! You’ve fired the NUT 就成功了
/var/ups/upsifttt.sh test Congratulations! You've fired the NUT event
重啟服務
service nut-client restart * Restarting NUT - power device monitor and shutdown controller nut-client [ OK ]
使用upsmon -c fsd驗證
upsmon -c fsd Network UPS Tools upsmon 2.7.4 Broadcast message from (somewhere) (Sat Apr 11 13:25:12 20 Executing automatic power-fail shutdown Broadcast message from (somewhere) (Sat Apr 11 13:25:12 20 Auto logout and shutdown proceeding
