Template only works with locally attached UPS

[dmth]

Today I figured out the template only works with locally attached UPSes.

If NUT is used in netclient mode, the script ups_status.sh has to be extended with the hostname of the nut-server at three locations.

I have the same issue, can you please show me how to change the script in order to use It in netclient mode ?

Thanks

Bump of this same question. Can you give details on the script edit for using netclient mode? Thanks

Another bump of this question.

How do we add the hostname to ups_status.sh in that it pulls the hostname as a variable.

ooooh, sorry guys I didn't check on my GH notifications for a long time. I didn't intend to keep you hanging. Apparently I figured it out but i never supplied a solution. Here's my patch for the problem. You need to replace YOURHOSTSIP with the IP of your host. If you are not familiar with the patch format: Replace the lines beginning with - by the lines beginning with + in your ups_status.sh and add the line below ups=$1

I know that this is a super old forum post, but here's my modified script (with help from ChatGPT) that uses the upsmon.conf to do the discovery in case this helps someone else.
In my case, I have one "master" NUT server that monitors a bunch of other NUT servers that are connected to UPSs that don't have SNMP. This also allows me to see all the UPSs on the same web server.

#!/bin/bash
#
# Zabbix NUT UPS discovery + metrics
# Uses /etc/nut/upsmon.conf MONITOR entries
#

UPS="$1"
KEY="$2"

UPSC="/bin/upsc"
UPSMON_CONF="/etc/nut/upsmon.conf"

# Ensure upsc exists
command -v "$UPSC" >/dev/null 2>&1 || { echo 0; exit 1; }

#
# ---- UPS DISCOVERY (LLD) ----
#
if [[ "$UPS" == "ups.discovery" ]]; then
    # If upsmon.conf is missing or unreadable, return empty discovery
    if [[ ! -r "$UPSMON_CONF" ]]; then
        echo '{ "data": [] }'
        exit 0
    fi

    echo '{ "data": ['
    first=1

    while read -r upsentry; do
        [[ -z "$upsentry" ]] && continue

        if [[ $first -eq 0 ]]; then
            echo ","
        fi

        echo -n "  { \"{#UPSNAME}\": \"$upsentry\" }"
        first=0
    done < <(awk '/^MONITOR/ { print $2 }' "$UPSMON_CONF")

    echo '] }'
    exit 0
