# System monitoring

The purpose of system monitoring is to monitor OneSpan Authentication Server via a management application and an SNMP server to request information from OneSpan Authentication Server. System monitoring also serves to alert administrators of certain events that originate in different system components.

System monitoring requires one or more notification targets to be defined to specify the output format. The available target formats are:

- SMS
- Email
- SNMP traps

To monitor the system via SNMP, for instance to be notified about events via SNMP traps and to process these traps, SNMP must be configured. For detailed information on system monitoring, querying the SNMP server, using SNMP and configuring notification targets, refer to the [OneSpan Authentication Server Product Guide](/sec/docs/oas-product-guide-3-28) and the [OneSpan Authentication Server Administrator Guide](/sec/docs/oas-administrator-guide-3-28).

## SNMP MIB

SNMP uses an MIB as a data store. OneSpan Authentication Server supports a number of MIB modules (also referred to as MIBs).

The MIB files can be found in:

- %PROGRAMFILES%\VASCO\IDENTIKEY Authentication Server\mibs on Microsoft Windows
- /opt/vasco/ias/mibs on Linux

Please refer to the documentation for your SNMP manager for instructions on how to install these MIB modules.

### MIB table
