Filtering notifications and alarms

You can use the NotificationFilter and AlarmFilter properties to limit the alarms and notifications that the probe acquires from the ZTE EMS.

When you use these properties, you must use the actual token names. For example, the token h represents the element NV_PERCEIVED_SEVERITY. So to specify that the probe is only sent notifications with a perceived severity of 3, set the NotificationFilter property to $h == 3.

You can specify more complex filters using AND, OR, and NOT operators. For example, to specify that the probe is sent notifications with a perceived severity of 3 or 4, set the NotificationFilter property to the following value:

($h == 3) OR ($h == 4)

You can use e and h as notification filter or alarm filter properties.

If the probe is acquiring events from ZTE LTE RAN, you can use c, d, e, f, g, h, l, m, n, s, y, z, jj, b, kk, a, k, ll, u, mm for alarm filtering, and c, d, e, b.time, h for notification filtering.

If the probe is acquiring events from ZTE LTE CN, you can use c, d, e, f, g ,h, k.time, l, m, n, s, y, z, b.time for alarm filtering, and c, d, e, b.time for notification filtering.

Note: To filter for

b.time
or b

, the values must be in corba time and not real time.

The following table lists the token mappings that can be used with the AlarmFilter and NotificationFilter properties:
