A Node consists of one or more Instances, which are individual machines (virtual or physical) running the Catchpoint node software.
To view and manage your Instances, navigate to the Nodes Module 
and select "Instances."
This displays the Instances list.
The following information is displayed for each Instance.
Column Name | Description |
|---|---|
| Instance Name | Unique name assigned to this instance |
| Status | Active - the instance claims a license and functions as part of a Node Inactive - the instance does not claim a license and does not function |
| OS | The operating system version running on the instance |
| Hardware | The make and model of the physical hardware running the instance (not applicable for instances installed in virtual environments) |
| Cores | The number of processor cores available to the instance |
| Memory | The amount of memory (in gigabytes) available to the instance |
| Version | The version number of the Catchpoint node software running on the instance |
| Chrome | The version(s) of Chrome available for use in web monitors on the instance |
| Internal IP | The internal IP address assigned to the instance |
| External IP | The external IP address that the instance is communicating from |
| DNS | The address of the DNS server the instance is configured to use |
| Proxy | The address of the internet proxy the instance is configured to use (if any) |
| Node ID | The unique identifier of the Node this instance is part of |
Last Contact | The date and time that this instance last communicated with the Catchpoint Scheduler. (Active instances normally communicate with Catchpoint every few seconds) |
Activating/Deactivating Instances
To activate or deactivate instances, select the checkbox next to each desired instance in the list, and then click "Activate" or "Deactivate" at the top. You can also hover your cursor over an instance and then click the ellipses that appears, and select the "Activate" or "Deactivate" option.
Configuring Instances
To access the properties blade for an instance, hover your cursor over an instance and then click the ellipses that appears and select "Properties." This launches the Instance Properties blade. Make any desired changes and click "Save."
Note that DNS and Proxy settings must be configured via the command line on the instance itself. Instructions for both are provided below, as well as in the Instance Properties blade.
DNS Settings
To override DNS settings on your instance, log into the machine and use the Catchpoint utility to make the change.
$ catchpoint dns [<DNS server(s)>]
Replace <DNS server(s)> with one or more IP addresses. Separate multiple IP addresses with commas.
Use the following command for more help on setting up DNS:
$ man catchpoint
Proxy Settings
To set up proxy on your instance, log into the machine and use the catchpoint proxy command to make the change.
$ catchpoint proxy --type=<DIRECT|STATIC|PAC>
The proxy command accepts the following arguments:
| Argument | Description |
|---|---|
| --type=<proxy_type> | proxy_type: DIRECT (default, no proxy), STATIC, or PAC |
| --host=<hostname> | The hostname/URI of the Proxy server. Format depends on proxy type |
| --port=<port_number> | The port number to connect to the Proxy. |
| --user=<username> | Proxy server Username when using a Static Proxy. |
| --password=<password> | Proxy server Password when using a Static Proxy. |
For more help on setting up proxy, enter the command $ man catchpoint
