When you are running automations in production, it is important to know that your system is available and responsive:

Verify that RAM and CPU meet the recommended specifications. Add more memory if required to improve the overall RAM usage.
Make sure dependencies have been installed with recommended versions (RabbitMQ, Redis, MongoDB, etc).
Check Release Notes for the latest Maintenance Release to view any changes or updates that may have occurred. Be sure to review all Product Notices to ensure you are well informed of any Deprecations associated with the Platform's release versions, including information provided in the Breaking Changes.

 RabbitMQ is only applicable to the 2022.1.x and 2023.1.x release versions of Itential Platform.
Check the status of all dependencies (RabbitMQ, Redis, MongoDB, etc) using the status commands below:
```
systemctl status mongod.service
systemctl status rabbitmq-server
systemctl status redis
```

If the dependencies have not started, use the commands below to start them:

systemctl start mongod.service
systemctl start rabbitmq-server
systemctl start redis

Check to ensure the status of the pronghorn service is up. If not, use this start command:
```
systemctl start pronghorn
```
To check the local host status, the most common link used will be the domain name followed by status:
```
https://(your domain)/status
```
Check for any zombie or stalled process related to Itential Platform using this command:
```
ps -ef|grep Z
```
Kill any zombie processes found and then restart the service.
