# Custom MIBs

Enginsight provides a wide range of Management Information Base (MIB) files by default for monitoring via the Simple Network Management Protocol (SNMP). You can also upload vendor-specific or custom MIB files to the Enginsight Platform.

{% hint style="warning" %}
**Please note**: The file must be in **.mib**, **.my**, or **.txt** format and must not exceed **10 MB**. The API must be configured accordingly for larger files.
{% endhint %}

{% hint style="danger" %}
**Please note**: To use a newly uploaded MIB file, you must [restart the associated Watchdog](#restart-watchdog).
{% endhint %}

<i class="fa-compass">:compass:</i> Navigate to **Observations** → **SNMP** → **Custom MIBs** to display a list of all uploaded MIB files. If you have not uploaded a custom MIB file yet, this view is empty.

The MIB Files Overview displays the name of each MIB. You can also [upload custom MIB files](#upload-mib).
