Team,

Thanks for the above post.

But recently I am facing a problem to send Zabbix WhatsApp alert to WhatsApp group using group id. It says "No session". Seems to be its blocked by WhatsApp.

Any other solution will be helpful.

/snapshot/dist-ncc/index.js:139006
throw new errors.SessionError("No sessions");
^
SessionError: No sessions

Hi inqwaynej

Actually at this time, I also looking for best way to send alert from Zabbix into whatsapp
some youtobe videos seems good, but need to fulfill the requirement, like use their whatsapp API / webhook

This video share how to send zabbix chart to whatsapp group

https://www.youtube.com/watch?v=CH67ePM1NJA

I'm still stuck how to replicate it using another whatsapp API gateway, the one I've tried using WAHA

https://waha.devlike.pro

Another Whatsapp API Gateway using this one

https://github.com/aldinokemal/go-whatsapp-web-multidevice

Script in zabbix alertscripts

cat alert_zabbix.sh
URL="http://whatsapp-api:3000/send/message"
PHONE="phone number"
TITLE="$2"
MESSAGE="$TITLE$3"

curl --location --request POST "$URL" \
--header 'Content-Type: application/json' \
--data-raw "{
\"phone\": \"${PHONE}\",
\"message\": \"${MESSAGE}\"
}"

Glad If somebody have better way to sending zabbix alert into whatsapp

Thanks

I expect the API is more stable, but you'd need to pay for that. Mudslide does logout from time to time and needs to be re-linked to the account.

Mudslide can send messages to groups. You just need to find the group id. You can see which groups (with the group id) the account is a member of with "mudslide groups"

For charts, Mudslide can send images and attachments. There are example on the Github readme https://github.com/robvanderleek/mud...-an-image-file

Good day,

Please add to point 5, "Add media type to Zabbix":

Script parameters: {ALERT.SENDTO}
Script parameters: {ALERT.MESSAGE}

Thank you very much for the information.

Thanks for pointing that out Victor, can't figure out how to edit the original post though.

First post from a long time Zabbix user.

I've been looking for a while for a way to send Zabbix notifications from WhatsApp. I struggled to find a simple solution that still worked on Debian 11. I eventually stumbled on a project called Mudslide. I was initially put off by the need for docker/NPM, which I'm not familiar with, but I found pre-compiled binaries which I was able to use. I thought I'd share some notes for anyone who may be interested. Below are my notes using Mudslide with Zabbix 6.4 on Debian 11.

1. Download the pre-compiled binary for mudslide
From https://github.com/robvanderleek/mud...tform-binaries

wget https://github.com/robvanderleek/mudslide/releases/download/0.25.1/mudslide-linuxstatic-x64

2. Make executable and move to /usr/local/bin

chmod +x mudslide-linuxstatic-x64
mv mudslide-linuxstatic-x64 /usr/local/bin/mudslide

3. Create alert script.
Our alert script is more complex in order to filter out some notifications. The script hasn't been tested, but it should work.

vi /usr/lib/zabbix/alertscripts/whatsapp

#!/bin/bash
mudslide -c /tmp/mudslide-cache send $1 "$2"

chmod +x /usr/lib/zabbix/alertscripts/whatsapp

4. Login to WhatsApp
Command below displays a QR code to login as a linked device.

sudo -u zabbix mudslide -c /tmp/mudslide-cache login

5. Add media type to Zabbix
Add media type to Zabbix from the WebUI. Alerts > Media types. I cloned the SMS media type and changed the following:

Name:         WhatsApp
Type:         Script
Script name:  whatsapp

6. Adding media to users
Use the full number with country code for "Send to" when adding media for a user. No preceding 0's or "+". e.g. 442079460000 (UK), 12065550100 (US)
Messages can also be sent to groups. Use the group ID in "Send to". Group IDs can be found from CLI with:

sudo -u zabbix mudslide -c /tmp/mudslide-cache groups

This will fetch the groups the account is currently a member of.

Note on the cache folder:
The Zabbix user on our system does not have a home folder, so we use /tmp/mudslide-cache for the cache folder. The cache contains login information. /tmp is cleared on reboot so you'll need to login on each reboot or change the cache folder. The cache folder does need to be writeable by the Zabbix user. I work around this I sync the folder to another location with cron:

vi /usr/local/bin/mudslide-cache-sync.sh

#!/bin/bash
# This script syncs the mudslide cache from /tmp to /var/cache. This is to work around the cache being cleared every time the server is rebooted.
# First rsync files from the backup to the cache. "-u" prevents overwriting newer files. This will also recreate the folder if it has been removed.
rsync -quazvh --copy-as=zabbix:zabbix /var/cache/mudslide/* /tmp/mudslide-cache/
# Then sync any updated files from the cache to the back-up.
rsync -qazvh /tmp/mudslide-cache/* /var/cache/mudslide/
​

chmod +x /usr/local/bin/mudslide-cache-sync.sh
cd /etc/cron.hourly
ln -s /usr/local/bin/mudslide-cache-sync.sh mudslide-cache-sync

Hope this has been useful.
