Description: H3C MIB for syslog management configuring remote log hosts, log severity levels, and message format settings.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is H3C-SYSLOG-MIB?

H3C-SYSLOG-MIB is an H3C proprietary MIB for configuring the device's syslog subsystem, covering remote log host destinations, message severity-level filtering, and log message format settings. Although no sample objects were supplied, syslog-configuration MIBs of this kind typically expose a table of configured log hosts (IP/port/facility), severity threshold settings per module or globally, and format/timestamp options. Its monitoring relevance is largely indirect: syslog itself is a primary channel through which hardware and software fault events (link flaps, hardware failures, authentication failures, process crashes) are reported off-device, so confirming this MIB's configuration (log hosts reachable, appropriate severity levels enabled) is important groundwork for ensuring fault visibility, even though the MIB's own objects are configuration rather than live fault data. It has no strong dependency on other MIBs beyond general device management conventions. It is deployed across the H3C product line wherever centralized syslog collection is used for operational monitoring, typically after an H3C-SYSLOG-MIB download to load its definitions into a MIB browser or NMS.

IPNetwork Monitor allows you to monitor SNMP objects defined in H3C-SYSLOG-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

  • H3C switches and routers with syslog remote logging configured

Monitoring Examples

Without concrete sample objects, exact table/column names cannot be confirmed; conceptually, an administrator would poll a syslog host table to verify the correct remote collector IP addresses are configured and check severity-level settings to ensure critical and warning-level hardware/software events are not being filtered out before reaching the log server. This entry should be revisited once the actual object tree can be inspected for precise names.

What Can Be Monitored

  • configured remote syslog hosts
  • log severity filtering
  • log message format settings

How to Use in IPNetwork Monitor

Example using h3cLogbufferOverwrittenMessages OID:

Select an H3C switch/router (syslog remote logging config) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type h3cLogbufferOverwrittenMessages into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. The number of log messages overwritten in logbuffer. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.
