[How-To] Valheim monitoring or other udp services

I was looking for a way to monitor valheim with uptime kuma which is not (yet?) possible with Uptime Kuma. But I found a workaround which could help a few people.

I’ve installed nginx on my valheim server. I’ve added a cronjob which checks every minute if the process is running and post a 1 into a html file, if not echo a 0 into it.

* * * * * if [ $(pidof ./valheim_server.x86_64) ]; then echo 1 > /var/www/html/index.html; else echo 0 > /var/www/html/index.html;fi

Then I used the HTTP(s) Keyword request to look for a 1 at given address.

Note: If this “Issue” isnt valid just delete it.

1. Create script nano /opt/check_service.sh

#!/bin/bash

service=$1
url=$2

if [ -z "$url" ] || [ -z "$service"]
  then
    echo "argument missing"
    echo "usage check_service.sh [servicename] [push URL]"
    exit
fi

/bin/systemctl -q is-active "$service.service"
status=$?
if [ "$status" == 0 ]; then
    curl --silent --output /dev/null $url
fi

1. make executable chmod +x /opt/check_service.sh

2. create contab, run every minute crontab -e * * * * * /opt/check_service.sh [[YOUR_SERVICENAME_HERE]] [[YOUR_UPTiME_PUSH_URL_HERE]] > /dev/null

3. enjoy 😃

Could be more reliable and easier to check your Valheim Server status using the steam api…

You get your api key here: https://steamcommunity.com/dev/apikey

This would be the link to a site that gives you all information available for your server in json format: https://api.steampowered.com/IGameServersService/GetServerList/v1/?filter=\appid\892970\addr\your-server-ip:port&key=steamapikey

The “appid” above is already the Valheim app ID - you can of course get this info for other servers, too, just check on steam.

You can see an example of how it is implemented on a website here

If it is using steam server, uptime kuma is already supported it.
