- select a host
- create a new ITEM:
- Name: (my) check if file /tmp/test exists
- Type: Zabbix agent
- Key: vfs.file.exists[/tmp/test]
- Update interval: 1m
- create a nuew TRIGGER:
- Name: (my) raise error if file /tmp/test exists
- Severity: Disaster
- Expression: last(/bakura.swgalaxy/vfs.file.exists[/tmp/test])=1
# Setup notifications to Opsgenie using webhook
###############################################
# https://www.zabbix.com/integrations/opsgenie
From Opsgenie we need:
- Opsgenie API URL: https://api.eu.opsgenie.com/v2/alerts
- Your 0psgenie API KEY (token): 58798dad-fd7f-4f97-a4cc-85a45174fb29
- Your Opsgenie Web URL: https://swgalaxy.app.opsgenie.com
In Zabbix:
1. Setup an Opsgenie media type
- define the global macro {$ZABBIX.URL}=<your ZABBIX URL>, example {$ZABBIX.URL}=http://192.168.0.91
(Menu: Administration/Macros)
- Create a copy pf Opsgenie media type (export in yaml, change media type name, import from yaml)
(Menu: Alerts/Media type)
- In your new Opsgenie media type, configure:
- opsgenie_api
- opsgenie_token
- opsgenie_web
- Enable the media type and test:
- alert_message: MEDIA TYPE TEST
- event_id: 12345
- event_source: 0
- event_update_status: 0
- event_value: 1
2. Associate the media type with User profile
- Menu: User settings/Profile/Media
- Click on Add
- Send to: <put a string> (not used but mandatory to add)
- customize (defaults values seems to be good)
- Don't forget to click on Update button
3. Enable triggering alerts to administrators via all media
- Menu: Alerts / Actions / Trigger Actions
- Enable the action: Report problems to Zabbix administrators
(the value of Operation should be: Send message to user groups: Zabbix administrators via all media)
# using zabbix_sender to send custom values
###########################################
On the host bakura.swgalaxy I will create a new item:
Name: (my) item from zabbix_sender
Type: Zabbix trapper
Key: my_key_custom_integer
Type of information: Numeric (unsigned)
From the host bakura.swgalaxy:
/app/oracle/zabbix_agent/bin/zabbix_sender -c /app/oracle/zabbix_agent/conf/zabbix_agentd.conf -s "bakura.swgalaxy" -k my_key_custom_integer -o 39
