Simple Bash script that uses the custom alert script functionality within Zabbix with the incoming web-hook feature of Slack.
This is tested and with Zabbix 3.4.x, should also work with greater versions.
This zabbix_slack_alert.sh script needs to be placed in the AlertScriptsPath directory that is specified within the Zabbix servers' configuration file (zabbix_server.conf) and must be executable:
[root@zabbix ~]# grep AlertScriptsPath /etc/zabbix/zabbix_server.conf
### Option: AlertScriptsPath
AlertScriptsPath=/usr/lib/zabbix/alertscripts
[root@zabbix ~]# ls -lah /usr/lib/zabbix/alertscripts/zabbix_slack_alert.sh
-rwxr-xr-x 1 root root 1,9K Ruj 21 12:59 /usr/lib/zabbix/alertscripts/zabbix_slack_alert.sh
If you do change AlertScriptsPath (or any other values) within zabbix_server.conf, a restart of the Zabbix server service is required.
When logged in to the Zabbix servers web interface with super-administrator privileges, navigate to the "Administration" tab, access the "Media Types" sub-tab, and click the "Create media type" button.
You need to create a media type as follows:
-
Name: Slack
-
Type: Script
-
Script name: zabbix_slack_alert.sh
-
Script parameters:
{ALERT.SENDTO}{ALERT.SUBJECT}{ALERT.MESSAGE}
...as shown here:
Add media to user of your choice and enable that media. Save and thats it.
