Apache2 wont start due to PiHole using ports 80/443. Changes apache ports to 8080/44301. sudo nano /etc/apache2/ports.conf

Getting SNMP to expose UPS Data

sudo apt install snmp snmpd libsnmp-dev snmp-mibs-downloader

Everything was going smoothly until running:

$ snmpwalk -v2c -c cyberpower .1.3.6.1.4.1.8072.1.3.2.4.1.2
$ Timeout: No Response from 192.168.1.218

Following this git guide to scrape the upsstats page, but since the apache port was changed, snmpd was looking in the right location.

SNMPD does not use port 80, so it shouldn’t be an issue.
