# How to prevent vCenter excessive logging

## Issue

When monitoring host environment, there is logging activity made by ControlUp. In some cases it might cause the ESX logs to grow. ![ESX logs](https://cdn.document360.io/098100b7-b9da-4bea-b4b9-017140ab863e/Images/Documentation/image%28234%29.png)

## Cause

ControlUp Real-Time DX Console/Monitor logs in to the vCenter and retrieve the hypervisor information and then logs out. The login/log out process occurs about every 5 seconds.

## Solution

You can change the connection to the hypervisor to be persistent.

To define persistent connection to the hypervisor, first define a data collector:

1. In the Real-Time DX Console, right-click the hypervisor and select **Connections settings**  

![edit hypervisor Connection popup](https://cdn.document360.io/098100b7-b9da-4bea-b4b9-017140ab863e/Images/Documentation/image%28235%29.png)

By default, any Console/Monitor will connect to your hypervisor. To save bandwidth, you can set up a relay or data collector.

1. Remove the Console/Monitor and choose one of the agents to be the data collector.

In the example above, **LVSITARGET03** collects the data and all consoles and monitors connect to that agent, to retrieve hypervisor performance metrics data (rather than the default console/monitor data collector). ![LVSITARGET03 under Connection options area of edit hypervisor Connection popup](https://cdn.document360.io/098100b7-b9da-4bea-b4b9-017140ab863e/Images/Documentation/image%28237%29.png)

1. Set a persistent connection between the agent and the hypervisor, by editing the registry of the agent's endpoint and creating the following key:

```
HKLM\SOFTWARE\Smart-X\ControlUp\Agent\vmDataCollector
```

Then create a new DWORD value named `vCenterPersistentConnection` and set the value to `1` (0 = default mode, 1 = persistent mode).
