標準展開での Splunk AppDynamics Services のインストール

標準展開オプションでは、Splunk AppDynamics オンプレミス仮想アプライアンス は Kubernetes クラスターにインフラストラクチャと Splunk AppDynamics Services をインストールします。

Prepare to Install Splunk AppDynamics Services

  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) Add any custom CA certificates for Controller outbound traffic by configuring appdController.customCaCerts in Customize the Helm File.
    2. (Optional) Enable the self-monitoring for the Controller.
      enableClusterAgent: true
  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
    注: 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:
    注: If you are running this script for the first time, copy the code for plain YAML. If you are running this script after installing the services, copy the code for encrypted YAML.
    Plain YAML
    #!/bin/bash
set -euo pipefail
TENANT=$(helm secrets decrypt /var/appd/config/secrets.yaml  .hybrid.controller.tenantAccountName)
DNS_DOMAIN=$(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
    Encrypted YAML
    #!/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. 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. See ingress in Customize the Helm File for instructions on how to configure the custom ingress certificate and key.
  7. Copy the license files as the license.lic file to the node in the following location.
    cd /var/appd/config
    This license is 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.
    注: 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. Follow the steps to add EUM account and license key:

    1. From Account Settings, select the Controller account that have EUM licenses and click Edit.

    2. Enter the EUM license key and the EUM account name in the EUM License Key and the EUM Account Name fields.

    3. Click Save.

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
    注:
  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
    注: You must re-login to the terminal if the following error is displayed:
    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]
    Small Profile
    appdcli start appd small
    Medium Profile
    appdcli start appd medium

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

Install Universal Integration Layer Service

To integrate Splunk AppDynamics 自己ホスト型仮想アプライアンス with Splunk Enterprise, you must install the Universal Integration Layer (UIL) service in the cluster:
  1. Log in to the cluster node console.
  2. Run the command to install the service:
    Small Profile
    appdcli start uil small
    Medium Profile
    appdcli start uil medium
    Large Profile
    appdcli start uil large
  3. Verify the status of the installed pods and service endpoints:
    • Pods: kubectl get pods -n cisco-uil

      The status of the universal integration layer pod must be displayed as Running.

      uil_pods

    • Service endpoints: appdcli ping

      The status of the UIL service should be displayed as Success.

      uil_service_endpoints

    You can also access the endpoint URL to verify the installation. See Verify the Service Endpoints Paths.

To continue with the integration, see Integrate Splunk AppDynamics 自己ホスト型仮想アプライアンス with Splunk Enterprise.

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. Follow the steps to add EUM account and license key:

      1. From Account Settings, select the Controller account that have EUM licenses and click Edit.

      2. Enter the EUM license key and the EUM account name in the EUM License Key and the EUM Account Name fields.

      3. Click Save.

    For more information, see Virtual Appliance CLI.

Verify the Service Endpoints Paths

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

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