Install Cisco AppDynamics Services in the Standard Deployment

With the standard deployment option, Splunk AppDynamics On-Premises Virtual Appliance installs infrastructure and Splunk AppDynamics Services in your Kubernetes cluster.

Prepare to Install Splunk AppDynamics Services

Complete the following steps to prepare the environment:

  1. Log in to one of the node console using the appduser credentials.
  2. Navigate to the following folder:
    cd /var/appd/config
  3. Edit the globals.yaml.gotmpl file with the required configuration.
    vi globals.yaml.gotmpl
    1. (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

      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
    2. (Optional) Add any custom CA certificates for Controller outbound traffic by configuring appdController.customCaCerts in Customize the Helm File.
    3. (Optional) Disable the self-monitoring for the Controller.
      enableClusterAgent: false
  4. (Optional) Edit the /var/appd/config/secrets.yaml file to update usernames and passwords of the Splunk AppDynamics Services.
    vi /var/appd/config/secrets.yaml
    Note: When you install the Splunk AppDynamics service, the secrets.yaml file becomes encrypted.
    See Edit the secrets.yaml.encrypted file.
  5. Save the following script to the console of your primary virtual appliance node as dnsinfo.sh and run it. Follow the instructions in its output:
    #!/bin/bash
set -euo pipefail
TENANT=$(helm secrets decrypt /var/appd/config/secrets.yaml.encrypted  | yq .hybrid.controller.tenantAccountName)
DNS_DOMAIN=$(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}\'

for server_name in "${TENANT}.auth.${DNS_DOMAIN}" "${TENANT}-tnt-authn.${DNS_DOMAIN}"; do
  if ! getent hosts "${server_name}" > /dev/null; then
    echo "Please double-check that DNS can resolve '${server_name}' as the VA ingress IP"
  fi
done

    Sample output:

    Verify the Virtual Appliance tenant should be 'customer1'
Verify the Virtual Appliance domain name should be 'va.mycompany.com'
Please double-check that DNS can resolve 'customer1.auth.va.mycompany.com' as the VA ingress IP
Please double-check that DNS can resolve 'customer1-tnt-authn.va.mycompany.com' as the VA ingress IP
  6. Copy the license files as the license.lic file to the node in the following location.
    cd /var/appd/config
    This license will be automatically used to provision Splunk AppDynamics Services. If you do not have the license file at this time, you can apply the license and provision the services later using appdcli.
    Note: For End User Monitoring, if you are using the Infrastructure-based Licensing model, make sure to specify EUM account and license key in the Administration Console. See Access the Administration Console.

Create a Three-Node Cluster

Note: Skip creating a three-node cluster for the demo profile.
  1. Log in to the primary node console.
  2. Verify the boot status of each node of the cluster:
    appdctl show boot
    Note:

    • 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>
  4. Run the following command to verify the node status:
    appdctl show cluster
microk8s status

    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
    Note: You must re-login to the terminal if the following error appears:
    Insufficient Permissions to Access Microk8s

Install Services in the Cluster

  1. Log in to the cluster node console.
  2. Run the command to install services:
    appdcli start appd [Profile]
    Demo Profile
    appdcli start appd demo
    Small Profile
    appdcli start appd small
    Medium Profile
    appdcli start appd medium
    Large Profile
    appdcli start appd large

    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.

Install the Anomaly Detection Services in the Cluster

  1. Log in to the cluster node console.
  2. Run the command to install services:
    Demo Profile
    appdcli start aiops demo
    Small Profile
    appdcli start aiops small

仮想アプライアンスに自動トランザクション診断サービスをインストールする手順は次のとおりです。

  1. クラスターノードコンソールにログインします。
  2. コマンドを実行して、サービスをインストールします。
    デモプロファイル
    appdcli start atd demo
    小規模プロファイル
    appdcli start atd small
    中規模プロファイル
    appdcli start atd medium
  3. インストールされたポッドとサービスエンドポイントのステータスを確認します。
    kubectl get pods -ncisco-atd

    ATD の詳細については、「自動トランザクション診断のワークフロー」を参照してください。

Apply Licenses to Splunk AppDynamics Services

Use appdcli to apply licenses after installing Splunk AppDynamics Services.

  1. Log in to the cluster node console.
  2. Copy the license files as the license.lic file to the node in the following location.
    cd /var/appd/config
  3. Run the following commands to apply licenses:
    Controller

    Update the Controller license.

    appdcli license controller license.lic
    End User Monitoring
    1. Update the EUM license.
      appdcli license eum license.lic
    2. (Optional) If you are using the Infrastructure-based Licensing model, make sure to specify EUM account and license key in the Administration Console. See Access the Administration Console.
For more information, see Virtual Appliance CLI.

Verify the Service Endpoints Paths

The Ingress controller checks the URL of an incoming request and redirects to the respective Splunk AppDynamics Service.

Service EndpointInstallation Path
Controllerhttps://<ingress>/controller
Events

https://<ingress>/events

https://<Node-IP>:32105/events

End User MonitoringAggregatorhttps://<ingress>/eumaggregator
Screenshotshttps://<ingress>/screenshots
Collectorhttps://<ingress>/eumcollector
SyntheticShepherdhttps://<ingress>/synthetic/shepherd
Schedulerhttps://<ingress>/synthetic/scheduler
Feederhttps://<ingress>/synthetic/feeder

Log in to the Controller UI by accessing https://<DNS-Name>or<Cluster-Node-IP>/.

Note: By default, the Controller UI username is set to admin and the password is set to welcome.
