Description: Huawei task MIB for monitoring system scheduled tasks, process execution status, and background job management.

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 HUAWEI-TASK-MIB?

HUAWEI-TASK-MIB describes the active system tasks running on a Huawei device's internal operating system, including each task's status and general identifying information, per its module description. Its data category is process/job status: a list of running system tasks and their execution state. Its monitoring value is directly software-status oriented: it lets an operator see whether internal management or protocol processes are running normally, and a task reporting as suspended, blocked, or missing when it should be active signals an internal software fault, such as a hung protocol daemon, that could otherwise go unnoticed until it causes a visible outage. It complements the standards-based HOST-RESOURCES-MIB's hrSWRunTable concept but is scoped to Huawei's own internal device task scheduler rather than a general-purpose host OS. It is deployed for internal diagnostics on Huawei routers and switches, typically pulled by vendor diagnostic tools or an NMS doing deep health checks. Network engineers evaluating or troubleshooting this functionality can download the HUAWEI-TASK-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in HUAWEI-TASK-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

Huawei routers and switches (internal OS/task diagnostics)

Monitoring Examples

No sample object names were provided for this module. In general, an operator or diagnostic tool would poll the task table to enumerate currently active system tasks along with each one's status. A task that is expected to be running but instead shows as suspended, stopped, or absent from the table points to an internal software fault, such as a hung management-plane or protocol process, that would otherwise only surface later as a functional failure.

What Can Be Monitored

active system task list
task execution status (running/suspended/stopped)
task general information
total task count

How to Use in IPNetwork Monitor

Example using hwTaskCpuUsage OID:

Select a Huawei router or switch (internal OS/task diagnostics) 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 hwTaskCpuUsage 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. It reports the cpu usage information of this task(0%-100%).If a task's cpu usage is more than 90, it means that the task is very busy. 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 Gauge32-type OID, Value bounds is the most useful condition here — trigger an alert if utilization exceeds 85%, a common warning threshold before sustained high load affects performance. Click Finish to create the monitor; you can adjust any parameter later.
