Description: HP StorageWorks LeftHand Networks MIB for managing NTP time synchronization configuration on HP P4000 storage nodes.
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 LEFTHAND-NETWORKS-NSM-NTP-MIB?
LEFTHAND-NETWORKS-NSM-NTP-MIB is a vendor-specific SNMP module from HP StorageWorks/LeftHand Networks for managing NTP time-synchronization configuration on HP P4000 (LeftHand NSM) SAN storage nodes. It exposes a small table of configured NTP servers along with the node's current GMT time and time zone setting. Although narrow in scope, it supports monitoring configuration/software status by letting an administrator confirm the storage node's clock source count, current system time, and time zone are correctly set, since clock drift can corrupt log correlation and cluster consistency across a storage cluster. It is a companion module to LeftHand's broader NUS/NSM MIB family (info and status MIBs) rather than a standalone standard, layered on top of standard NTP concepts. It is typically deployed in HP LeftHand/StoreVirtual SAN clusters where time synchronization across nodes is essential for clustered storage operations, and administrators can download the LEFTHAND-NETWORKS-NSM-NTP-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in LEFTHAND-NETWORKS-NSM-NTP-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
- HP StorageWorks P4000 storage node
- HP LeftHand Networks NSM SAN appliance
Monitoring Examples
An administrator polls ntpTable (sized by ntpCount) to confirm the expected number of NTP servers are configured on the node. timeGMTTime and timeTimeZone are checked to verify the node's clock and zone match the rest of the cluster, catching configuration drift that could otherwise cause log timestamp mismatches during a storage incident investigation. If ntpCount unexpectedly drops to zero, that flags a lost NTP configuration needing remediation.
What Can Be Monitored
- configured NTP server count
- current system GMT time
- configured time zone
