You can install the various PingIntelligence components as a systemd service. Installing as a service, the various components are started automatically when the host system restarts. You require sudo access to install PingIntelligence components as a service. Complete the following steps only if the automated deployment did not install PingIntelligence components as a service. Run the following command on the host machine for which you want to verify that is service is installed or not:

# systemctl status <service-name>

For example, to check ASE service, enter the following command on ASE host machine:

systemctl status pi-ase.service
● ase.service - ASE
  Loaded: loaded (/etc/systemd/system/ase.service; disabled; vendor preset: disabled)
  Active: active (running) since Sun 2019-11-03 23:01:19 MST; 23h ago
