Execute dynatrace.sh bash script updated on Thu, 22 Aug 2019 08:55:07 +0200

Thu, 22 Aug 2019 08:55:07 +0200

Dynatrace Managed software consists of a number of Dynatrace services that are dependent on each other and should be stopped or started in a particular order. You can use the official dynatrace.sh script with additional parameters to properly start, stop, or restart Dynatrace services. By default, the script is located at /opt/dynatrace-managed/launcher/. Make sure the dynatrace.sh script has executable permissions.

You can execute the dynatrace.sh script with a parameter (start, stop, restart, status, check, pid) as described below.

start
Starts all Dynatrace Managed required services in the recommended order.
```
[root@localhost]# ./dynatrace.sh start
```
stop
Stops all Dynatrace Managed required services in the recommended order.
```
[root@localhost]# ./dynatrace.sh stop
```
restart
Restarts all Dynatrace Managed required services in the recommended order.
```
[root@localhost]# ./dynatrace.sh restart
```
status
Displays a list of Dynatrace required services and the status of each, including detailed information about each service:
```
[root@localhost]# ./dynatrace.sh status
```
