Description: H3C MIB for the Information Center logging subsystem managing log output destinations, severity filters, and channels.

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-INFOCENTER-MIB?

H3C-INFOCENTER-MIB is an H3C-specific MIB for managing the device's Information Center logging subsystem, which controls internal log buffering and log forwarding to external syslog hosts. It exposes the configured and current size of the internal log buffer, counts of messages currently held, overwritten, and dropped from that buffer, a table of log-buffer content entries, and configuration for log-host destinations (source interface, timestamp format, maximum log hosts). As a software/system-health monitoring MIB it lets an operator verify that logging is capturing events without loss — rising h3cICLogbufferOverwrittenMessages or h3cICLogbufferDroppedMessages indicates the log buffer is too small or messages are being generated faster than they can be processed/forwarded, a useful early indicator of a device under stress or a misconfigured logging pipeline. It has no explicit external MIB dependency stated, being self-contained for H3C's Info Center feature. It is typically deployed across H3C switches and routers wherever centralized syslog collection and local log-buffer health need to be monitored. Engineers can download the H3C-INFOCENTER-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in H3C-INFOCENTER-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.

H3C switches and routers

Monitoring Examples

Polling h3cICLogbufferCurrentMessages against h3cICMaxLogbufferSize/h3cICLogbufferSize shows how full the local log buffer is, while h3cICLogbufferOverwrittenMessages and h3cICLogbufferDroppedMessages reveal whether messages are being lost. The h3cICLogbufferContTable / h3cICLogbufferContEntry (h3cICLogbufferContIndex, h3cICLogbufferContDescription) lets an admin inspect actual buffered log content per channel. Checking h3cICLoghostSourceInterface and h3cICLoghostTimestampType confirms syslog messages sent to external log hosts carry the expected source and timestamp format.

What Can Be Monitored

log buffer size and current usage
overwritten/dropped log message counts
buffered log content
syslog host configuration

How to Use in IPNetwork Monitor

Example using h3cICLogbufferOverwrittenMessages OID:

Select an H3C switch/router (Info Center logging subsystem) 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 h3cICLogbufferOverwrittenMessages into the Find box to locate it in the OID tree, 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.
