This document explains about how to send Instana Events directly to WAIOps 3.2.0 AIMgr through Kafka topic.

1. Process

  1. A Microservice called WAIOps Hub to be installed in WAIOps cluster.
  2. Instana can send alers to WAIOps Hub via Webhook.
  3. This WAIOps Hub will convert the instana events to NOI events and push the events to NOI Kafka topic in AIMgr.
  4. AIMgr will process the event and create Alerts.

2. Installation

The WAIOps Hub can be installed via the script files/deploy-waiops-hub.sh. Here are the steps.

1. Update NAMESPACE property

In the above script file, update the below property to point to WAIOps AIMgr installed namespace

NAMESPACE=cp4waiops

2. Update NOI_KAFKA_TOPIC property

Update the below property to point to NOI Kafka topic that is created in AIMgr.

NOI_KAFKA_TOPIC=cp4waiops-cartridge-alerts-noi-7buu27a3

3. Severity Filter property (Optional)

This property helps to process only the instana events that contains severity in the given range.

This is optional and leave the below default values as it is to skip the severity filter.

FILTER_SEVERITY_ENABLED=false
FILTER_SEVERITY_FROM=1
FILTER_SEVERITY_TO=1000

If you want to enable the severity filter, you can modify them.

  • FILTER_SEVERITY_ENABLED - true
  • FILTER_SEVERITY_FROM - Severity start value
  • FILTER_SEVERITY_TO - Severity end value

4. Login into OCP Cluster

Login into the OCP Cluster where WAIOps AIMgr is installed

oc login ....

5. Install the WAIOps Hub

Run the script to install the WAIOps Hub microservice.

sh files/deploy-waiops-hub.sh

As a result, the WebHook url will be printed like the below.

===============================================================

WebHook URL : http://waiops-hub-core-waiops-hub-ns.aiops-320-4c84f197-0000.eu-de.containers.appdomain.cloud/api/core/instanaEvent

6. Create Instana Alert Channel

Create Instana alert channel with webhook and give the above printed url.
