Testing

Go to Dynatrace -> One agent -> Linux

1. Download one agent
2. verify signature
3. Install Oneagent as a privilaged user

Use below command:

/bin/sh Dynatrace-OneAgent-Linux-x86-1.xxx.xx.xxx-xxx.sh --set-monitoring-mode=fullstack --set-app-log-content-access=true

In case if you are installing latest/unsupported bversion you can skip OS Check using SKIP_OS_SUPPORT_CHECK=true

/bin/sh Dynatrace-OneAgent-Linux-x86-1.xxx.xx.xxx-xxx.sh --set-monitoring-mode=fullstack --set-app-log-content-access=true SKIP_OS_SUPPORT_CHECK=true

Generate traffic

while true; do
  curl -s http://localhost:8079/ > /dev/null
  sleep 2
done
