In a hybrid deployment, Splunk AppDynamics On-Premises Virtual Appliance leverages your current Controller, Events Service, and End User Monitoring components from Splunk AppDynamics On-Premises and installs Anomaly Detection and Cisco Secure Application Services in your Kubernetes cluster.

Prepare to Install Splunk AppDynamics Services

Complete the following steps to prepare the environment:

  1. Enable SSL on your standalone Controller. See Controller SSL and Certificates. 
  2. Log into the console of the primary node using the appduser credentials.
    This node is considered as the primary node after you create a three-node cluster.

  3. Navigate to the following folder:

    cd /var/appd/config
    CODE

  4. Edit the globals.yaml.gotmpl file with the required configuration.

    vi globals.yaml.gotmpl
    CODE
    1. Specify the Controller key and the account name.
    2. Enable the hybrid mode.
    3. Set the Controller domain name.
    4. Configure the port to access the standalone Controller.
    5. Set the sslEnabled field to true.
    6. Upload the Controller CA certificates for the standalone Controller.
    7. Configure the MySQL host. It is the same host as the Controller domain.
    8. Configure a port for the standalone Controller database.
    9. Update the MySQL CA certificates, which are located in <controller-home>/platform/product/controller/db/data/ca.pem.
    10. (Optional) Update CA certificates for Kafka in the hybrid.kafka section of globals.yaml.gotmpl.
    11. (Optional) Configure a custom ingress certificate (by default the ingress controller installs a fully-configured self-signed certificate). The custom ingress certificate needs certain SANs added to it. Run the following script on the console of your primary node to view a list of SANs. Add those SANs to your custom ingress certificate. See ingress in Customize the Helm File for instructions on how to configure the custom ingress certificate and key. 
      #!/bin/bash
set -euo pipefail
TENANT=$(helm secrets decrypt /var/appd/config/secrets.yaml.encrypted  | yq .hybrid.controller.tenantAccountName)
DNS_DOMAIN=$(grep -v "^ *\t* *{{" /var/appd/config/globals.yaml.gotmpl | yq -r '.dnsDomain')
DNS_NAMES=$(grep -v "^ *\t* *{{" /var/appd/config/globals.yaml.gotmpl | yq -r '.dnsNames|join(" ")')
echo Verify the Virtual Appliance tenant should be \'${TENANT}\'
echo Verify the Virtual Appliance domain name should be \'${DNS_DOMAIN}\'
echo Verify the Virtual Appliance node names are: ${DNS_NAMES}

echo If creating and importing into VA a Custom Ingress Certificate, include the following SANs:
for server_name in "$DNS_DOMAIN" "${TENANT}.${DNS_DOMAIN}" "*.${DNS_DOMAIN}" "${TENANT}.auth.${DNS_DOMAIN}" "${TENANT}-tnt-authn.${DNS_DOMAIN}" $DNS_NAMES; do
        echo "  ${server_name}"
done
      BASH

      Sample output of the script above: 
      Verify the Virtual Appliance tenant should be 'customer1'
Verify the Virtual Appliance domain name should be 'va.mycompany.com'
Verify the Virtual Appliance node names are: localhost vanodename-1
If creating and importing into VA a Custom Ingress Certificate, include the following SANs:
  va.mycompany.com
  customer1.va.mycompany.com
  *.va.mycompany.com
  customer1.auth.va.mycompany.com
  customer1-tnt-authn.va.mycompany.com
  localhost
  vanodename-1
      BASH



  5. Edit the/var/appd/config/secrets.yaml file to update the following:

    vi secrets.yaml
    CODE

    1. Update the Controller and MySQL credentials.

      hybrid:
  controller:
    controllerKey: <string>
    tenantAccountName: <tenant-name>
    rootUsername: root
    rootPassword: '<root-password>'
    rootAccountname: system
    adminUsername: admin
    adminPassword: '<admin-password>'
  mysql:
    dbUser: secapp
    dbPassword: '<string>'
      YML
    2. Edit the usernames and passwords of the Splunk AppDynamics services.

      When you install the Splunk AppDynamics service, the secrets.yaml file becomes encrypted.


      See Edit the secrets.yaml.encrypted File.
  6. Save the following script on the console of your primary virtual appliance node as hybridinfo.sh and run it. Follow the instructions in its output: 
    #!/bin/bash
set -euo pipefail
TENANT=$(helm secrets decrypt /var/appd/config/secrets.yaml.encrypted  | yq .hybrid.controller.tenantAccountName)
CONTROLLER_DNS_DOMAIN=$(grep -v "^ *\t* *{{" /var/appd/config/globals.yaml.gotmpl | yq -r '.hybrid.controller.domainName')
DNS_DOMAIN=$(grep -v "^ *\t* *{{" /var/appd/config/globals.yaml.gotmpl | yq -r '.dnsDomain')
echo Verify the Virtual Appliance tenant should be \'${TENANT}\'
echo Verify the Virtual Appliance domain name should be \'${DNS_DOMAIN}\'
echo Verify the Controller domain name should be \'${CONTROLLER_DNS_DOMAIN}\'
 
echo When creating and importing the Controller Server Certificate, include the following SANs:
for server_name in "${CONTROLLER_DNS_DOMAIN}" "${TENANT}-tnt-con.${DNS_DOMAIN}" "${TENANT}-tnt-con.${CONTROLLER_DNS_DOMAIN}"; do
  echo "  ${server_name}"
done
for server_name in "$CONTROLLER_DNS_DOMAIN" "${TENANT}.${CONTROLLER_DNS_DOMAIN}" "${TENANT}-tnt-con.${DNS_DOMAIN}" "${TENANT}-tnt-con.${CONTROLLER_DNS_DOMAIN}"; do
  if ! getent hosts "${server_name}" > /dev/null; then
    echo "Please add DNS entry for ${server_name} for controller host IP, VA is not able to resolve it currently"
  fi
done
for server_name in "${TENANT}.auth.${DNS_DOMAIN}" "${TENANT}-tnt-authn.${DNS_DOMAIN}"; do
  if ! getent hosts "${server_name}" > /dev/null; then
    echo "Please double-check on standalone controller that DNS can resolve entry for ${server_name} as VA ingress IP"
  fi
done
    BASH

    Sample script invocation: 
    appduser@nodename-1:~$ bash ./hybridinfo.sh
    BASH

    Sample output: 
    Verify the Virtual Appliance tenant should be 'customer1'
Verify the Virtual Appliance domain name should be 'va.mycompany.com'
Verify the Controller domain name should be 'controller.mycompany.com' 
When creating and importing the Controller Server Certificate, include the following SANs:
  controller.mycompany.com
  customer1-tnt-con.va.mycompany.com
  customer1-tnt-con.controller.mycompany.com
Please add DNS entry for controller.mycompany.com for controller host IP, VA is not able to resolve it currently
Please add DNS entry for customer1.controller.mycompany.com for controller host IP, VA is not able to resolve it currently
Please add DNS entry for customer1-tnt-con.va.mycompany.com for controller host IP, VA is not able to resolve it currently
Please add DNS entry for customer1-tnt-con.controller.mycompany.com for controller host IP, VA is not able to resolve it currently
Please double-check on standalone controller that DNS can resolve entry for customer1.auth.va.mycompany.com as VA ingress IP
Please double-check on standalone controller that DNS can resolve entry for customer1-tnt-authn.va.mycompany.com as VA ingress IP
    BASH


  7. Update the firewall rules to allow the standalone Controller to access the Kafka ports in the Kubernetes cluster. Update the firewall rule in each cluster node.

    sudo ufw allow AppdNodePorts
    CODE

Create a Three-Node Cluster

  1. Log in to the primary node console.
  2. Verify the boot status of each node of the cluster:
    appdctl show boot
    CODE
    • Ensure the status of the services in each node appears as Success. Else, restart the virtual machine that failed.
      If it is still failing, you might have to redeploy the virtual machine.
    • Ensure to configure the same time on all the cluster nodes.

  3. Run the following command in the primary node and specify the IP address of the peer nodes:

    cd /home/appduser
appdctl cluster init <Node-2-IP> <Node-3-IP>
    CODE

  4. Run the following command to verify the node status:

    appdctl show cluster
microk8s status
    CODE

    Ensure that the output displays the Running status as true for the nodes that are part of the cluster.

    Sample Output

     NODE           | ROLE  | RUNNING 
----------------+-------+---------
 10.0.0.1:19001 | voter | true    
 10.0.0.2:19001 | voter | true    
 10.0.0.3:19001 | voter | true
    CODE

    You must re-login to the terminal if the following error appears:

    Insufficient Permissions to Access Microk8s
    CODE

Configure the Standalone Controller in Splunk AppDynamics On-Premises

  1. Log in to the Controller database by using the following path:
    <controller-home>/bin/controller.sh login-db
    CODE
  2. Connect to the MySQL database.
  3. Run this command on the Virtual Appliance primary node to get the value of dbUser: 
    helm secrets decrypt /var/appd/config/secrets.yaml.encrypted | yq .hybrid.mysql.dbUser
    BASH
  4. Run this command on the Virtual Appliance primary node to get the value of dbPassword: 
    helm secrets decrypt /var/appd/config/secrets.yaml.encrypted | yq .hybrid.mysql.dbPassword
    BASH
  5.  Drop and create the <dbUser> for Cisco Secure Application Services and grant permissions to access the Controller database, replacing <dbUser> and <dbPassword> with the values you retrieved: 
    DROP USER <dbUser>;
CREATE USER '<dbUser>'@'%' identified by '<dbPassword>' REQUIRE SSL;
GRANT USAGE ON *.* TO `<dbUser>`@`%`;
GRANT SELECT  ON `controller`.* TO `<dbUser>`@`%`;
    BASH

Install Services in the Cluster

  1. Log in to the cluster node console.

  2. Run the command to install services:

    appdcli start appd small
    CODE 
    appdcli start appd medium
    CODE



    This command installs the Splunk AppDynamics services. We recommend you to specify the VA profile as same as the profile that you selected to create a virtual machine. See, Virtual Appliance Sizing.

    Sample Output

    CODE
  3.  Verify the status of the installed pods and service endpoints:
    • Pods: kubectl get pods --all-namespaces

Generate the Hybrid Configuration File

If you skipped updating the CA certificates, you must regenerate hybrid configuration file after restarting a Virtual Appliance service.


  1. Run the script to connect the Kafka node ports with the standalone controller:

    appduser@appd-demo-2:~/appd-charts/utils$ bash prepare-hybrid.sh
    CODE

    Sample Output

    Writing Kafka CA Cert
Writing Schema registry CA Cert
Writing AnomalyDetectionKafkaSSLProducer
Writing AnomalyDetectionKafkaConsumerSSL
Writing configure script
Creating archive of hybrid config
hybrid-config/
hybrid-config/kafka-ca.crt
hybrid-config/AnomalyDetectionKafkaConsumerSSL
hybrid-config/configure.sh
hybrid-config/schema-registry-ca.crt
hybrid-config/AnomalyDetectionKafkaSSLProducer
Completed
    CODE

    This script generates the hybrid-config.tar file that includes the required configuration files.

  2. Copy the hybrid-config.tar file to your standalone controller instance.
  3. Locate and extract the hybrid-config.tar file contents.

Configure the Controller Properties by Using the Kubernetes Cluster CLI

If you skipped updating the CA certificates, you must configure this controller properties using the Kubernetes cluster CLI after restarting a Virtual Appliance service.


  1. Log in to your Kubernetes Cluster.

  2. Run the command to update the standalone Controller properties:

    appdcli run bootstrap_hybrid
    CODE

    This command configures the following properties in the Controller:

    Key: anomaly.detection.enabled, Value: true
Key: anomaly.detection.deployed.onprem, Value: true
Key: controller.id, Value: onprem
Key: controller.unique.id, Value: onprem
Key: anomaly.detection.kafka.consumer.group.id, Value: pi-alarmservice-transition-consumer-group-onprem
Key: anomaly.detection.kafka.consumer.topic, Value: pi-alarmservice-transition-onprem
Key: anomaly.detection.kafka.producer.topic, Value: metadata-lifecycle-events
Key: anomaly.detection.onprem.output.topic, Value: blitz-processed-metrics
Key: anomaly.detection.schema.registry.enabled, Value: true
Key: anomaly.detection.consumer.schema.registry.url, Value: https://10.0.0.1.nip.io/schemaregistry
Key: anomaly.detection.producer.schema.registry.url, Value: https://10.0.0.2.nip.io/schemaregistry
Key: anomaly.detection.kafka.consumer.bootstrap.servers, Value: 10.0.0.1:32101
Key: anomaly.detection.kafka.producer.bootstrap.servers, Value: 10.0.0.2:32102
Key: anomaly.detection.kafka.producer.ssl.enabled, Value: true
Key: anomaly.detection.kafka.consumer.ssl.enabled, Value: true
Key: anomaly.detection.service.url, Value: https://10.0.0.1.nip.io/pi
    CODE

    Alternatively, you can access the administration console by using the Kubernetes cluster IP address and manually edit each parameter.

  3. Run the configure.sh script to provision the controller with certs and secrets to connect to Kubernetes cluster:
    This script is extracted from the hybrid-config.tar file. See, how to obtain hybrid-config.tar file.

    $ bash configure.sh
Usage: configure.sh <controller-home> <keystore-passwd>
Using controller home as /opt/appdynamics and keystore password as changeit
Do you want to proceed? (y/n): y
Creating Kafka truststore
Certificate was added to keystore
Creating schema registry truststore
Certificate was added to keystore
Writing obfuscated producer config
Writing obfuscated consumer config
Completed
    CODE
  4. Restart the Controller using these commands:
    cd ~/appdynamics/platform/product/controller/bin/
./controller.sh stop
./controller.sh start
    CODE

Install the Anomaly Detection Services in the Cluster

  1. Log in to the cluster node console.

  2. Run the command to install services:

    appdcli start aiops small
    CODE 
    appdcli start aiops medium
    CODE


  3. Verify the status of the installed pods and service endpoints:

    • Pods: kubectl get pods --all-namespaces

    • Service endpoints: appdcli ping

See Anomaly Detection.

Sometimes, IOException error occurs when you access Anomaly Detection in the Controller UI. See Troubleshoot Virtual Appliance Issues.


(Optional) Install Cisco Secure Application
