Zabbix

Prerequisites:

This section explains on how to integrate and ingest alerts from Zabbix monitoring tool into CloudFabrix AIOPs platform.

Zabbix supports alert notifications via email, sms, script or webhook. CloudFabrix AIOPs platform uses webhook notification method from Zabbix to receive and ingest the alerts or events.

Click here for Alert Sources to create a Webhook URL for Zabbix alert notifications in CloudFabrix OIA application.

Configure Zabbix for Alert notifications over a Webhook:

Step 1: Login to Zabbix monitoring tool through web-browser UI

Step 2: On left menu, expand 'Administration' and click on 'Media types'

Step 3: Click on 'Create media type'

Step 4: Click on ‘Media type’, Enter name for the Webhook and select 'Type' as 'Webhook' from the drop down.

Step 5: As highlighted in the above screen, add the below parameters.

Alert_Date => {EVENT.DATE}
Alert_HostAddress => {HOST.IP}
Alert_Hostname => {HOST.NAME}
Alert_RecoveryDate => {EVENT.RECOVERY.DATE}
Alert_RecoveryTime => {EVENT.RECOVERY.TIME}
Alert_RecoveryName => {EVENT.RECOVERY.NAME}
Alert_RecoveryTags => {EVENT.RECOVERY.TAGSJSON}
Alert_ServiceDescription => {EVENT.NAME}
Alert_ServiceEventId => {EVENT.ID}
Alert_ServiceOutput => {EVENT.OPDATA}
Alert_ServiceSeverity => {EVENT.SEVERITY}
Alert_Time => {EVENT.TIME}
Alert_Status => {EVENT.STATUS}
Alert_Message => {ALERT.MESSAGE}
Alert_HostGroup => {TRIGGER.HOSTGROUP.NAME}
Alert_Tags => {EVENT.TAGSJSON}
Alert_Template => {TRIGGER.TEMPLATE.NAME}
Alert_WebHookURL => {ALERT.SENDTO}

Step 6: Edit the 'Script' field and add the below Java script

var params = JSON.parse(value),
req = new CurlHttpRequest(),
resp;
req.AddHeader('Content-Type: application/json');
//req.AddHeader('Authorization: Basic <base64encoded - username:password>');
//Below example when HTTP Basic authentication is used for Webhook, 
//Username: cfxuser, Password: cfxuser
//req.AddHeader('Authorization: Basic Y2Z4dXNlcjpjZnh1c2Vy');

var params = JSON.parse(value);
payload = {};
payload.Alert_ServiceEventId = params.Alert_ServiceEventId;
payload.Alert_HostName = params.Alert_HostName;
payload.Alert_HostAddress = params.Alert_HostAddress;
payload.Alert_Date = params.Alert_Date;
payload.Alert_Time = params.Alert_Time;
payload.Alert_ServiceSeverity = params.Alert_ServiceSeverity;
payload.Alert_ServiceDescription = params.Alert_ServiceDescription;
payload.Alert_ServiceOutput = params.Alert_ServiceOutput;
payload.Alert_Message = params.Alert_Message;
payload.Alert_RecoveryDate = params.Alert_RecoveryDate;
payload.Alert_RecoveryTime = params.Alert_RecoveryTime;
payload.Alert_RecoveryName = params.Alert_RecoveryName;
payload.Alert_RecoveryTags = params.Alert_RecoveryTags;
payload.Alert_Status = params.Alert_Status;
payload.Alert_HostGroup = params.Alert_HostGroup;
payload.Alert_Tags = params.Alert_Tags;
payload.Alert_Template = params.Alert_Template;
resp = req.Post(params.Alert_WebHookURL,
JSON.stringify(payload)
    );
return resp;

Step 7: Click on 'Apply' to save the Script

Step 8: Make sure 'Enabled' is check-box is checked.

Step 9: Click on 'Message Templates' tab and click on 'Add' as show in the below screen

Step 11: Click on 'Add' to add another Message Template. From 'Message Type' drop down menu, select 'Problem recovery', Enter Subject as 'Resolved in {EVENT.DURATION}: {EVENT.NAME}, leave 'Message' as blank and click on 'Add'

Step 12: Click on 'Add' to save the Webhook Media Type.

Step 13: On left menu, expand 'Administration' and click on 'User groups' to add a new user group with read-only permissions.

Step 14: Click on 'Create user group'

Step 15: Click on 'User group' tab, enter 'Group name' as 'cfx_notifications_group'

Step 16: Click on 'Permissions' tab, and click on 'Select' to select all groups

Step 23: Select 'CloudFabrix-Webhook' that was created in one of the step above (Step 4), and for 'Send to' field add the Webhook URL (created under Alert Sources section), leave the rest of fields as shown in below screen and Click 'Add'

Step 23: Click 'Add' button to complete in adding the Webhook notification in Zabbix.

Testing the Webhook notification: Under 'Media Type' section of the menu, select the Webhook that was created above and click on 'Test'

Note: If there is a test failure with error message 'cannot get URL: Couln't resolve hostname, httprequest.c.323 internal', edit the Webhook media type and enter the Webhook URL as a value for 'Alert_WebHookURL' attribute, save it and try the 'Test' connection again.

Zabbix Triggers: Please make sure to select 'PROBLEM event generation mode' as 'single' for sending Alert notifications to CloudFabrix AIOPs system. When 'multiple' option is selected, Zabbix generates a new event ID everytime it evaluates the condition of the trigger. CloudFabrix AIOps system uses the event ID to track the lifecycle of an event from open to closure. Below is the same screen for a reference.
