Description: HP-MCSG module

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 HP-MCSG?

HP-MCSG is a Hewlett-Packard private SNMP MIB for managing HP ServiceGuard clusters, a high-availability clustering technology historically used on HP-UX and related HP server platforms. It exposes cluster-specific attributes describing cluster membership, node state, and package/application status within a ServiceGuard cluster rather than network interface data. Its core monitoring purpose is software/service status — determining whether cluster nodes are up, whether failover packages (application groups) are running on their intended node, and detecting an unplanned failover, which is central to high-availability operations. It is a standalone HP proprietary MIB tailored to ServiceGuard's own clustering model rather than a general clustering standard. It is deployed in HP-UX/ServiceGuard high-availability server clusters running business-critical applications that require automatic failover. Engineers can download the HP-MCSG file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in HP-MCSG. 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

HP-UX server running ServiceGuard cluster software

Monitoring Examples

No concrete object names were present in the sampled source beyond the module description, so specifics cannot be confirmed here. Based on its stated purpose, an administrator would poll this module's cluster and node/package status objects to confirm all cluster nodes are active members and that critical application packages are still running on their designated primary node rather than having silently failed over.

What Can Be Monitored

cluster node membership status
package/application failover state
cluster node health

How to Use in IPNetwork Monitor

Example using hpmcSGPkgSvcRestartCount OID:

Select an HP-UX server running ServiceGuard cluster software 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 hpmcSGPkgSvcRestartCount 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 current number of times this service has been restarted. 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.
