Finding Equipment

In many cases, Critical Labs can find and connect your equipment automatically. To add equipment automatically, you will need the following:

  • A fully installed and functioning Critical Labs gateway
  • SNMP-enabled device(s) connected to the same network as the gateway
  • The subnet(s) on which the device(s) are located

Login to Critical Labs.

Once logged in, open the top-right menu and click on My Equipment.

Choose your gateway from the list.

You should now be on the gateway information screen. Click the Add button located to the top-right of the list of Equipment.

A popup will display. Make sure the Find Equipment option is selected, then click the Find Equipment button.

This will take you to the Find Equipment page. Most times, a message will appear at the top of the screen indicating that it is waiting for the gateway to poll (blue message). You must wait until this message bar indicates that the gateway is listening (green message) in order to proceed.

Once the message indicates that the gateway is listening, optionally update the IP range to your chosen subnet, and add any SNMP community strings that Critical Labs should try. Click the Find Equipment button.

The Critical Labs gateway will now try to retrieve devices that are either SNMP-enabled or have web cards compatible with Critical Labs software. This may take a few minutes. If you leave this webpage while the discovery process is running, you will be unable to retrieve your discovered results.

Locked Devices

When Critical Labs finishes searching for devices, it will either return an empty list, indicating it couldn’t find any devices on the indicated subnet, or a list of devices. Sometimes Critical Labs will discover a device that is Locked – in other words, the device has a username and password that prevents Critical Labs from seeing information about the device. Locked devices will have the following icon:

Locked devices don’t inhibit Critical Labs from connecting to your device, but unlocking the device by providing the username and password will give you better visibility (and access to configuration).

If a locked device is detected on your network, Critical Labs will popup a message asking for the username and password. You may also click the Unlock Card option when a locked device is selected to provide credentials. Critical Labs does not store this username/password.

SNMP Status

There are three states of SNMP configuration that Critical Labs can detect: enabled (green), partially enabled (yellow), and not enabled (red).

Enabled Devices

Enabled devices are ready to be imported into Critical Labs. Critical Labs was able to communicate to the device fully and should have no trouble retrieving sensor data from the device.

Partially Enabled Devices

Partially enabled devices are devices that have SNMP enabled, but something is preventing Critical Labs from communicating with the device. This is usually a sign that either 1) the web card on that device needs to be configured, or 2) the community string on the device is different than the ones used for discovery.

Non-Enabled Devices

Not enabled devices either can’t speak SNMP or they haven’t been setup to speak SNMP yet. If the device does not have a Critical Labs-compatible web card, then this can also be an indication of a wrong community string. If the device has a Critical Labs-compatible web card, then Critical Labs will allow you to configure the card to speak SNMP to Critical Labs (the card username and password are required to change configuration).

Traps Status

Critical Labs-compatible web cards will display whether they are configured to send traps to Critical Labs or not.

If traps are not enabled, you can set them up during a card configuration.

Next Steps

Now that you know how to find equipment, you can add them to Critical Labs! If your equipment isn’t speaking SNMP to Critical Labs yet, make sure to check out Configuring Web Cards first.
