This isn't something the maintainer is going to do IMO.

If you'd like to do it I'll provide a solution.

1. Setup a Web Server (Use express or something along those lines)
2. Make it use commands over an RCON client on an interval (You can use https://github.com/radj307/ARRCON, or some language specific library)
3. Setup a discord webhook to publish this data
4. Profit!

I personally setup a similar solution to monitor my server on HomeAssisant

[jammsen]

Hey @SLYROOKO Could you please add an example scenario on how you would like this to work?

Because im pretty sure i can do online interval updates and send that to somewhere. Afaik the "player-joined-event" and something similar is afaik NOT accessable to me or the user, as well as other events. Server-Start and Interval-tasks like Backup and Restarts and Stop would be, i think, the only option to "send something somewhere".

But please explain what you mean in more detail.

This isn't something the maintainer is going to do IMO.

Hey @ericellb - I dont want to be mean, but how about we listen first and then assume the assumable? 😄

[SLYROOKO]

I was going to suggest monitoring the logs to get these events, but I see there is no way to get player login events. Maybe instead for now a good alternative would be an hourly update of current players online and a list of usernames, which could be obtained from the rcon with admin command "/ShowPlayers" and parse that output.

For the Server Status events:

• ENV var to set webhook URL
• ENV var for Custom Server Start Message and Server Shutdown message etc.

I'm all for listening, I didn't mean to step on any toes.

However I believe in the Unix Philosophy, and that a tool like this is best suited as its own image/service. I want to say love your maintenance on this so far, running smooth!

Yeah 😢

Yeah but im not sure if i would make a parser for this

• ENV var to set webhook URL
• ENV var for Custom Server Start Message and Server Shutdown message etc.

Would be 1 webhookurl and 9 VARS setup 3 events (title, description, color)

Example here:

[jammsen]

Thats just a test, would that be suffiecent?

[SLYROOKO]

Yep, perfectly suits my use case.

Actually, I just wrote a similar script to monitor the player online and offline. We can get the player online status by rcon, and regular update the data in our script, so that we can know player is online or offline when a new record appears or disappears.

BTW, I register a bot to discord to be want to do more things, so here is the code snip.

class PalworldBot(discord.Client):
    prev_online_players = []

    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)

    async def setup_hook(self) -> None:
        # create the background task and run it in the background
        self.check_online_players.start()

    async def on_ready(self):
        print(f'Logged on as {self.user}!')
        print('------')

    async def get_online_players(self):
        timeout = 1
        command = "showplayers"
        #print("get_online_players()")
        players = []
        text = await rcon(command, host=rcon_addr, port=rcon_port, passwd=rcon_passwd, timeout=timeout)
        if text:
           print(text, flush=True)
           for line in text.splitlines():
               player = line.split(',')
               if len(player) != 3:        # not player
                   continue
               if player[0] == 'name':     # it's title
                   continue
               players.append(player)

        return players

    @tasks.loop(seconds=30)  # task runs every 30 seconds
    async def check_online_players(self):
        await self.wait_until_ready()
        online_players = await self.get_online_players()
        print(f"online_players = {online_players}")
        print(f"prev_online_players = {self.prev_online_players}")

        msg = ""
        channel = self.get_channel(discord_channel)  # channel ID goes here
        for player in online_players:
            if player not in self.prev_online_players:
                print(f"Player {player[0]} is online")
                msg = f"Player {player[0]} is online"
                await channel.send(msg)
        for player in self.prev_online_players:
            if player not in online_players:
                print(f"Player {player[0]} is offline")
                msg = f"Player {player[0]} is offline"
                await channel.send(msg)

        self.prev_online_players = online_players

Hey @SLYROOKO @acelan Would you be able for a Call in Discord to talk about this? I think the topic is up to a certain point easy to solve, BUT after that point this topic explodes with complexity.

My timezone is Germany. What would be yours?

[jammsen]

Hey @SLYROOKO @acelan I have added a start and stop function already pushed this to master. Please go ahead and try it out and give me feedback and please tell me if you would you be able for a Call in Discord to talk about this?

[SLYROOKO]

I'm U.S. East. I'll give it a test tonight and write my findings here. As for complexity of this topic, I assume it becomes a issue of use case. For me it is useful because it's a way to notify players of a server "hey your friends are playing right now" and "You can't log on? it's the server". Is there a particular use case you wanted to discuss? If so I have some time this weekend?

[SLYROOKO]

Working for Starting, Updating and Installing messages. Can't seem to get Server Stopped message to work.

[SLYROOKO]

Running on Synology Nas

[acelan]

I can see the 3 discord webhook messages shown correctly on my discord server.

You need to have the option enabled, in the same section in this script its writing the other messages you have. https://github.com/jammsen/docker-palworld-dedicated-server/blob/develop/servermanager.sh#L52

[jammsen]

@acelan @SLYROOKO Yes, use-case of "online-players" I dont now both of your timezones but im fine with the weekend or with late evening for me an like afternoon for you guys?

[acelan]

I'm fromTaiwan +8 timezone. I'm available all day from tomorrow, and the whole week next week. So, ping me anytime when you want to chat with me.

[jammsen]

Would be easier if you guys are in the Discord @acelan @SLYROOKO

Joined the DIscord. And yes WEBHOOK_ENABLED = true. I'm getting the other webhook messages, just not send_webhook_notification "$WEBHOOK_STOP_TITLE" "$WEBHOOK_STOP_DESCRIPTION" "$WEBHOOK_STOP_COLOR". It may have to do with the way container's are stopped in my OS seeing that other people are not seeing this problem. I suspect that all the processes stop before getting to that line.

Can somebody else running on synology os verify this?

[jammsen]

Hey @SLYROOKO I have added this to the term_handler which handles the clean-save-shutdown see here but your OS might just handle things in another weird way that doesnt trigger stuff in a good and normal way.

i could just move it to after https://github.com/jammsen/docker-palworld-dedicated-server/blob/develop/servermanager.sh#L74 Line 74.

Not sure if thats a clean way for the other stops though, would need to test that.

[jammsen]

Hey @SLYROOKO i have added another mechanic to catch other signals, i hope, with that, the new develop image is just done baking, please go ahead and try it out for me okay?

Feedback is a must 🤣 Need to know if that works and can be released to prod/latest.

[SLYROOKO]

Didn't work

[jammsen]

Hey @SLYROOKO - I tested it on 3 systems with 3 different tools and did work everywhere. I caught everything i could catch fresh a shell POV i think. Questions:

• Did you force download the latest develop (not latest) and did docker-compose down and after that up again?
• Whats your setup to work with Docker - Please explain in detail.

[SLYROOKO]

Yes, used [https://hub.docker.com/layers/jammsen/palworld-dedicated-server/develop/images/sha256-d93a14a2e88eb5260bceed218d631ce6d8c7398d8cd0713650eced69e922b0bf?context=explore]

OS: Synology OS created a new instance of this image on "container manager" program (gui container manager) Expected Behavior: After steam update and server is running fine, i stop the container expecting the server termination message. Actual: I see all the other webhook messages get sent. except the Server termination message. Logs show "broadcasted done"

[jammsen]

@SLYROOKO Thats why i wanted a call with you on the weekend 😞 but nothing happend.

I think Synology doesnt respect signal codes here, because very covered 2 out of 2 cases how the system will be terminated.

[jammsen]

The update is now on master/latest

[calvinli723]

Would it be possible to add support for webhooks in multiple discord servers?

[jammsen]

@calvinli723

Would it be possible to add support for webhooks in multiple discord servers?

Well at the moment the field is a "string" and thats solo for sending data.

I could rework it to be an array and then someone could add X amount of urls. The send-processing would need to be reworked, but i dont think that would a problem. But i dont have any idea if webhook urls, have sending limits per seconds/minutes/hours, that could be triggered here.

Possible yes, useful? Dont to the user to decide.

What you do had planned? @calvinli723

[calvinli723]

Rework into an array would work but we don't want to break existing configs that expect the variable to be just a string right? So maybe we can add another variable? Or is there some fancy shell script logic to check whether the variable has a string or a list in it?

[jammsen]

@calvinli723 Well some dark voodoo shell magic is always possible like checking if there is an ( or ) in the variable. But the other way works too. Add it to the Changelog, describe it as Breaking-Change and use an @ function in Discord or so. I think its all a matter of communication and transparency. But you have a point, maybe you are the edge-cass under 150 users, who wants this as only 1 person.
