This project provides scripts to temporarily increase the polling interval for UPS voltage monitoring on a farm server, enabling more frequent data collection and visualization.

• A script to configure NUT server, Prometheus, and Grafana for high-frequency UPS voltage data polling (once per second).

• Enable faster polling:

./grafana_poll_faster.sh fast

• Restore default monitoring configuration:

./grafana_poll_faster.sh back

• A script to poll local UPS voltage metrics and log changes.

• Polls the /ups_metrics endpoint every 0.04 seconds
• Logs voltage data to /tmp/ directory
• Records only voltage changes to minimize data storage

Run for default duration (one hour):

./local_poll.sh

Run in background for one hour:

./local_poll.sh &

Specify custom polling duration (in seconds) and run in the background:

./local_poll.sh 3600 &

• Requires access to local UPS metrics endpoint
• NUT server
• Prometheus
• Grafana

• Designed for temporary, high-frequency monitoring
• Helps track rapid voltage changes
