# These are automated notification scripts for the APC UPS
|
|
|
|
### Steps to setup are here: https://www.pontikis.net/blog/apc-ups-on-ubuntu-workstation
|
|
|
|
|
|
|
|
# How to setup
|
|
|
|
1. Install `sudo apt-get install ssmtp`
|
|
2. Enter your SMTP creds: `nano /etc/ssmtp/ssmtp.conf`
|
|
|
|
```
|
|
root=changeme@example.com
|
|
mailhub=smtp.example.com:587
|
|
AuthUser=your_username
|
|
AuthPass=your_password
|
|
UseTLS=YES # OR UseSTARTTLS=YES
|
|
|
|
```
|
|
3. Go to `/etc/apcupsd/` and edit the onbattery file. `nano /etc/apcupsd/onbattery`
|
|
|
|
it should look something like this:
|
|
|
|
```
|
|
#!/bin/sh
|
|
#
|
|
# This shell script if placed in /etc/apcupsd
|
|
# will be called by /etc/apcupsd/apccontrol when the UPS
|
|
# goes on batteries.
|
|
# We send an email message to root to notify him.
|
|
#
|
|
|
|
HOSTNAME=`hostname`
|
|
MSG="$HOSTNAME UPS $1 Power Failure !!!"
|
|
#
|
|
(
|
|
echo "$MSG"
|
|
echo " "
|
|
/sbin/apcaccess status
|
|
) | $APCUPSD_MAIL -s "$MSG" $SYSADMIN
|
|
exit 0
|
|
|
|
```
|
|
|
|
you'll want yours to look like this:
|
|
|
|
```
|
|
#!/bin/sh
|
|
#
|
|
# This shell script if placed in /etc/apcupsd
|
|
# will be called by /etc/apcupsd/apccontrol when the UPS
|
|
# goes on batteries.
|
|
# We send an email message to root to notify him.
|
|
#
|
|
|
|
HOSTNAME=`hostname`
|
|
MSG="$HOSTNAME UPS $1 Power Failure !!!"
|
|
#
|
|
(
|
|
echo "$MSG"
|
|
echo " "
|
|
/sbin/apcaccess status
|
|
) | $APCUPSD_MAIL -s "$MSG" $SYSADMIN
|
|
./etc/apcupsd/scripts/onbatt.sh
|
|
exit 0
|
|
|
|
```
|
|
|
|
4. Run these commands: `cd /etc/apcupsd/ && mkdir scripts && nano onbatt.sh`
|
|
|
|
then fill the `onbatt.sh` file with the contents from this github repo
|
|
|
|
5. Run these commands to grant permissions to the script and run it: `chmod +x ./onbatt.sh && ./onbatt.sh` and it should run some commands and send you the email! (it'll only send the email if the UPS has no power!)
|
|
|
|
# Setting up the battery alerts
|
|
|
|
1. Run these commands `nano /etc/apcupsd/scripts/lowbatt.sh` and fill it with the desired contents (do the same with the /etc/apcupsd/scripts/critlowbatt.sh).
|
|
2. Make sure to grant the right perms for the scripts: `chmod +x /etc/apcupsd/scripts/lowbatt.sh && chmod +x /etc/apcupsd/scripts/critlowbatt.sh`
|
|
3. Run this: `crontab -e` and scroll all the way to the bottom and paste these lines:
|
|
|
|
```
|
|
*/1 * * * * /bin/bash /etc/apcupsd/scripts/lowbatt.sh
|
|
*/1 * * * * /bin/bash /etc/apcupsd/scripts/critlowbatt.sh
|
|
|
|
```
|
|
and then `systemctl restart cron`
|
|
|
|
this will save the crontab file and start running the crons.
|
|
|
