Since the update of June 18th, all LibreNMS alerts were reset to unaknowledged. I had about 180 unacknowledged alerts 
At first I began to acknowledge each alert one by one, but I quickly became tired of it. I looked around but couldn’t find a way to quickly acknowledge all outstanding alerts. So I turned to Claude.ai and it gave me this bash script:
#!/bin/bash
# Configuration
API_TOKEN="YOUR-API-TOKEN-HERE"
LIBRENMS_URL="https://your-librenms-address-here"
# Function to acknowledge a single alert
ack_alert() {
local alert_id=$1
local note="$2"
echo "Acknowledging alert ID: $alert_id"
if [ -n "$note" ]; then
RESPONSE=$(curl -s -k -X PUT \
-H "X-Auth-Token: $API_TOKEN" \
-d "note=$note" \

else
RESPONSE=$(curl -s -k -X PUT \
-H "X-Auth-Token: $API_TOKEN" \
"$LIBRENMS_URL/api/v0/alerts/$alert_id")
fi
if echo "$RESPONSE" | jq -e '.status == "ok"' > /dev/null 2>&1; then

I ran the script for those alerts and it acknowledged every single one of them.
Here’s the log of another run I did today:
