Can the tgslurmbot be generalized to send messages to other users/groups?

[hariseldon99]

Hi,

I'm running goslmailer with tgslurmbot configged. As of now, the bot seems to only be able to communicate to its own chatid. I have a telegram group for my cluster where downtime/uptime announcements are made by another bot (basically an ugly python hack that I cooked up here). I'd like to have tgslurmbot do it, but I don't know the go language well enough to figure out how.

Hi,

Sorry for the hasty post. I actually figured out how to do it with http requests:

import requests
TOKEN = "YOUR TELEGRAM BOT TOKEN"
chat_id = "YOUR CHAT ID"
message = "hello from your telegram bot"
url = f"[https://api.telegram.org/bot{TOKEN}/sendMessage?chat_id={chat_id}&text={message](https://api.telegram.org/bot%7BTOKEN%7D/sendMessage?chat_id={chat_id}&text={message)}"
print(requests.get(url).json()) # this sends the message

Hey,
goslmailer telegram connector should be capable of sending messages to group chats same as to individual chats.
In your group, search and add the bot as the member and he should reply to /start and send messages about the job to the whole group.

Try it out and let me know if that is what you needed? (we tested this functionality long time ago and it worked., i hope it still works, unless telegram api changed in the meantime, then we'll update the code)

Hi.

If I give the slurm jobscript the chatid of the group, there is an error in the logs

$ grep mail cupy_test_mps.sbatch 
#SBATCH --mail-type=ALL
#SBATCH --mail-user="telegram:-1001215703471"

If I replace it with the chatid of the bot itself, it responds to me privately, but does not post to the group.

I'm sorry, i can not reproduce this, i've just now created this minimal config and the bot sends the message to the group chat as expected:

goslmailer.conf:

[root@ctl-0 slurm]# cat goslmailer.conf 
{
  "logfile": "/tmp/goslmailer.log",
  "debugconfig": true,
  "binpaths": {
    "sacct":"/bin/sacct",
    "sstat":"/bin/sstat"
  },
  "defaultconnector": "telegram",
  "connectors": {
    "telegram": {
      "name": "pjtestbot",
      "url": "",
      "token": "REDACTED",
      "renderToFile": "no",
      "spoolDir": "/tmp/telegramgobs",
      "messageTemplate": "/etc/slurm/telegramTemplate.html",
      "useLookup": "no",
      "format": "HTML"
    }
  },
  "qosmap": {
    "elevated": 3600,
    "normal": 28800
  }
}

goslmailer.log:

Did you add the bot to the group? He must be a part of the group to be able to send there. (afair)

EDIT: also, i've tested out the telegramTemplate.html from the release zip and that also seems to work as expected. Will close the #31 then.

[hariseldon99]

My cluster is down for maintainance. I'll post with updates in a few hours when it is back up.

In the meantime, AFAIK I did add the bot to the group, but I'll check the ID again to be sure that it's the right one.

Update: I used curl to send a message to the telegram group with the api key of the bot. It worked!

curl -X POST "https://api.telegram.org/bot<API-KEY-WUZ-HERE>/sendMessage" -d "chat_id=-1001215703472&text=Herp! Derp!"

However, I was unable to get slurm to do it. I'll update on this when the machine is back up.

[pja237]

ok, when the cluster is up, please check that:

1. make sure the correct bot/token is added to the group/config
2. the chatId you're using in slurm --mail-user=telegram:cid , came from that same bots reply to /start command in that group

[hariseldon99]

Hmm. It seems you were right. It's working now. I had to remove quotes from the command flag.

#SBATCH --mail-user="telegram:-1001215703472"

#SBATCH --mail-user=telegram:-1001215703472

Thanks.
