    Study Notes

    SolarWinds Orion MIBs and OIDs

    • Management Information Base (MIB) is a structure that describes objects a device reports on (CPU, fan, temperature).
    • MIB contains the object name, data type, and object identifier (OID).
    • MIB is a hierarchical structure (tree-like) where each entry is a value for a specific component on a device.
    • SolarWinds maintains a MIB database used to monitor network devices.
    • The database is compiled weekly.
    • Users are notified when the new MIB database is available.

    Usage of MIBs and OIDs in Orion

    • MIBs support the Orion SNMP Trap Server, which processes trap messages.
    • MIBs are used to create Universal Device Pollers, allowing customization of polled device data.
    • MIBs are used to create customized device pollers, requiring knowledge of OIDs to poll device data.

    OIDs

    • OIDs are unique numerical values used to specify entries in the MIB tree.
    • OIDs can be represented as sequences of numbers (e.g., 1.3.6.1).
    • OIDs can be searched for in the MIB tree using the SolarWinds UnDP application or the OID picker in the Create Poller Package wizard.

    SolarWinds Orion MIB

    • SolarWinds maintains a MIB database for monitoring a wide variety of network devices.
    • The current version of the MIB database is compiled weekly.
    • The database serves as a repository for OIDs.

    MIBs Not Used For

    • Identifying devices.
    • Updating the MIB database does not help identify new devices.
    • MIB database updates are separate from the sysobjectID database.

    Additional Resources

    • Trap templates format trap messages.
    • Trigger alerts are created when receiving specific syslog messages.
    • Syslog alert actions are defined and are available.

    What if OIDs are not in the MIB?

    • OIDs used for device studio pollers do not need to be in the SolarWinds MIB database.
    • If an OID is assigned to a device, NPM will try to poll it, regardless if it's in the database.
    • If needed, the Create Poller Package wizard can be used to manually add the OID.

    Other Topics

    • SNMP Get Types: GET, GET NEXT, and GET TABLE retrieve OID values, enabling polling methods for objects and tables.
    • Device Studio Technologies: Used for monitoring data on devices, with technologies for CPU and Memory usage, and Node Details.
    • Universal Device Poller (UnDP): Used to customize monitored stats.
    • NetPath requirements: Detailed requirements for probes, clarifying OS (like Windows Server), CPU cores, HD space and RAM are needed during probe setups to be connected to the monitored network to gather data.
    • Create a NetPath service/Add probes: Steps for creating and managing network paths to monitored devices.
    • How to troubleshoot NetPath problems: Specifics on troubleshooting slow connections to external monitored device and troubleshooting the cause.
    • Monitoring Cisco ASA firewalls in NPM (CLI polling): Explains how to enable or disable CLI polling in NPM.
    • Issues with SNMP and SNMPv3 details: Error handling and resolution steps for SNMPv3 problems.
    • Network Insight for Palo Alto firewalls: Accessing data and status of related Palo Alto configurations.
    • Status rollup mode: Configuration to describe how availability of multiple objects (like nodes on a network map) is shown at a glance.
    • Enabling hardware health monitoring: Steps and requirements on different devices to enable, check and/or edit hardware health monitoring.
    • Detect and predict duplex mismatches in NPM: Checking and resolving duplex mismatches for network interfaces.
    • Display physical layout of interfaces on graphical stencils (Device View): Interface viewing for Cisco devices (in the Device View tab).
