What Is NETI-CHMGR-MIB?

NETI-CHMGR-MIB is the Channel Manager MIB for Net Insight's Nimbra media transport network elements, providing a service-independent abstraction for managing connections and channels regardless of the specific service (video, audio, data) riding over them. It exposes configuration and descriptive data about objects managed by the channel manager: descriptor tables carrying capabilities, customer ID, service reference, acceptable/requested bandwidth (bps), and slot allocation for each channel object. While primarily a connection/service-provisioning MIB, it is used to monitor the operational and capacity status of transport channels, for example whether requested bandwidth and slots for a service could actually be granted, functioning as a software/service-health check on the node. It includes a notifications (trap) branch (chmgrNotifications), indicating it also reports fault/change events for channel objects. It is deployed within Net Insight Nimbra chassis used for broadcast and professional media transport networks, where operators need cross-service visibility into channel capacity and allocation, and administrators can download the NETI-CHMGR-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in NETI-CHMGR-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

  • Net Insight Nimbra media transport chassis

Monitoring Examples

An operator would poll chmgrODescriptionTable/chmgrODescriptionEntry for a given chmgrODescrIndex to compare chmgrODescrRequestedBps and chmgrODescrRequestedSlots against chmgrODescrAcceptableBps and chmgrODescrAcceptableSlots, confirming a media channel got the bandwidth/slot allocation it needed. If requested values exceed acceptable values, the entry reveals a capacity shortfall that would cause a media flow to fail to establish. chmgrODescriptionTimeStamp lets the operator confirm how recently the channel descriptor was updated, useful for detecting stale provisioning state, and chmgrNotifications would fire an alert if the channel's status changed unexpectedly.

What Can Be Monitored

  • channel descriptor capabilities
  • requested vs. acceptable bandwidth (bps)
  • requested vs. acceptable slot allocation
  • customer/service reference per channel
  • channel descriptor last-changed timestamp

How to Use in IPNetwork Monitor

Example using chmgrOStatDcap1Octets OID:

Select a Net Insight media transport chassis 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 chmgrOStatDcap1Octets 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 total number of out-bound octets (bytes) on the connection. 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.
