# VM Essentials Health

The VM Essentials Health section provides an overview of the health of your VM Essentials appliance. It includes an appliance health summary in the following areas:

- **CPU:** Appliance CPU usage is checked. If usage is greater than 50%, this indicator will be in a yellow or warning state. If VM Essentials is unable to complete the check, it will be in a red or error state. Depending on appliance performance and how frequently this indicator is in a warning state, it may be necessary to upgrade to increase CPU. The **Overall** health indicator will mirror the CPU health indicator
- **Memory:** If swap usage is above 60% or VM Essentials memory usage is above 95%, this indicator will be in a yellow or warning state. If VM Essentials is unable to complete the check for any reason, it will be in a red or error state. Depending on appliance performance and how frequently this indicator is in a warning state, it may be necessary to increase swap, upgrade the appliance to add memory, or consider a different appliance architecture for those using single-node appliances
- **Storage:** If utilization of the filesystem mounted at “/” exceeds 80%, this indicator will be in a yellow warned status. Above 90% will put this indicator in red or error status
- **Database:** The database is checked. If the number of database connections exceeds the configured maximum number of connections or if any test queries are reported as being slow, this indicator will be in a yellow or warning state. If VM Essentials is unable to communicate with the database, it will be in a red or error state. In the database section further down the page, you can check the number of maximum used connections against the number of max connections. In the case of database connections exceeding the maximum, consider increasing the maximum settings connection
- **Elastic:** Elasticsearch is polled for the health status of each index. If any indices are not reporting a “green” health status, this indicator will be in a yellow or warning state.
- **Queues:** RabbitMQ queues are checked. Any queues containing more than 1000 messages are considered to be in an error state. Appliance Queue health is given in a yellow or warning status when any queues are in such an error state. In the Queues section further down the page you can see the individual Queues listed and which have messages piling up. When the appliance is unable to complete the check for any reason, this indicator will be in a red or error state
