SNMP Device Catalog
Overview
The SNMP Device Catalog is a critical component in the process of discovering devices from network infrastructure. It is a repository of devices based on their OID, which is used during the discovery of devices in AIOps. When the discovery runs, the OID of the discovered devices is fetched using SNMP walk, and it is checked against the OIDs present in the catalog. Based on the match, a predefined template for monitoring in the monitoring screen and a monitor type are assigned to the discovered device, and it is then displayed in the monitor screen.
The SNMP Device Catalog screen not only contains the OID for the discovered devices, but it also includes the OID for the metrics that need to be monitored for all the network devices in the infrastructure.
Use-Case
In some cases, you may want to monitor specific metrics that are not monitored by AIOps by default. This might be new metrics added by the device vendor or even some custom metrics that you might want to create based on certain manipulation of the metric OIDs. In such cases, you can create a new record in the SNMP Device Catalog, where you can map the device OID with the metric OID that you want to poll. This allows AIOps to start polling this metric from the next poll.
Overall, the SNMP Device Catalog screen plays a crucial role in ensuring that your AIOps product can accurately discover and monitor network devices in your environment. By correctly configuring the catalog, you can ensure that your AIOps product provides valuable insights into the health and performance of your infrastructure.

How to start monitoring a new metric for a device?
SNMP Device Catalogs play a vital role in discovering and monitoring devices and metrics in an infrastructure. They contain information such as the device OID, vendor, and type, which is essential for your AIOps product to discover and monitor the devices accurately.
In some cases, a user might need to monitor specific metrics that are not monitored by AIOps. In such cases, the user can create a new record in the SNMP Device Catalog and map the device OID with the metric OID. Once this is done, the AIOps product will start polling the new metric from the next poll.
Additionally, creating a new SNMP Device Catalog record is also useful when a user needs to monitor devices from a new vendor or type that is not already available in the existing SNMP Device Catalog. By creating a new record, the user can configure the settings specific to the new vendor or type and ensure that the AIOps product can monitor the devices accurately.
Therefore, creating a new SNMP Device Catalog record is a necessary step for users who want to monitor specific metrics or devices that are not already included in the existing SNMP Device Catalog. It allows users to customize and configure the settings as required and ensures that the AIOps product provides accurate insights into the health and performance of their infrastructure.

Creating a Custom SNMP Device Catalog
In Motadata AIOps, you can create a custom SNMP Device Catalog to monitor specific metrics or devices that are not covered by default. To set up a custom catalog, follow the steps below to fill up the necessary details
| Field | Description |
|---|---|
| System OID | Enter the appropriate System OID for the device you want to monitor. The System OID uniquely identifies the device associated with the OID in the catalog. |
| Name | Provide a meaningful and descriptive name for the SNMP Device Catalog. This name will help you identify the catalog and differentiate it from others in your monitoring setup. |
| Vendor | Specify the vendor of the device associated with the OID. This information helps categorize the devices efficiently for better organization and management. |
| Type | Choose the type of device that is associated with the OID from the available options, such as router, switch, firewall, or other network devices. Selecting the correct device type is essential for accurate device discovery and monitoring. |
OID Groups
The OID Groups section allows you to categorize the OIDs that need to be monitored.
| OID Group Name | Each OID Group you create must have a unique name within the catalog. This name will be used to refer to the specific group, making it easier to manage and configure. |
| Scalar/Tabular | Select the appropriate OID type. - Scalar OIDs represent single, discrete values. These values may include metrics like CPU utilization or memory usage, represented by specific OIDs. - Tabular OIDs represent sets of related data, presented in a table format. These tables might include information about interfaces, network routes, etc. |
OID Listing
Under each OID Group, you can list individual OIDs and their corresponding names.
| OID Name | Assign a descriptive name to each OID, representing the metric or data you want to monitor. For example, you can use "CPU (%)" for CPU utilization. |
| OID | Provide the actual OID (Object Identifier) associated with the metric you want to monitor, e.g., 1.3.6.1.4.1.9.2.1.58.0 for CPU utilization. |
| Choose OID | If you are unsure about the OID to use, you can utilize the "Choose OID" feature to browse and select from available OIDs supported by the device. |
