Current Alarms

 

About the Current Alarms Page

To access this page, click the Monitor tab and then select Alarms>Current from the left-nav bar.

The Current Alarms page displays the table of outstanding alarms in your network. You can filter the table to see alarms for a specific device or a subset of devices, and you can acknowledge an alarm. Acknowledging an alarm allows you to indicate to other users that this alarm is being addressed.

See the TCX Series Optical Transport System Feature Guide for information on all alarms.

Tasks You Can Perform

You can perform the following tasks from this page:

  • View current alarms in the network or on a device.

  • Acknowledge or unacknowledge alarms.

Field Descriptions

Table 1 explains the headings in the Current Alarms page.

Table 1: Fields for the Current Alarms Page

Field

Description

Device

The IP address of the device.

Description

The alarm description as reported by the device for alarms generated by the device or as provided by the proNX Optical Director for alarms generated by the proNX Optical Director.

Source

The component that raised the alarm.

Time Raised

The date and time when the alarm was raised, in the following format:

YYYY-MM-DD HH:MM:SS ZZZZ

  • YYYY is the year

  • MM is the month

  • DD is the day

  • HH is the hour

  • MM is the minute

  • SS is the second

  • ZZZZ is the time zone represented as a UTC offset (for example, Eastern Daylight Time is specified as -0400)

Severity

Critical, major, or minor.

For alarms raised by the TCX Series elements, the following definitions apply:

  • Critical - service-affecting hardware failure

  • Major - service-affecting abnormal condition

  • Minor - non-service-affecting abnormal condition

Viewing Current Alarms

Use this procedure to view current alarms for a device.

  1. Click the Monitor tab and then select Alarms>Current from the left-nav bar.

    The Current Alarms table is displayed:

    By default, the alarms are sorted first by Severity then by Time Raised.

    Note

    This table is updated automatically as alarms occur.

  2. To see all alarms, all acknowledged alarms, or all unacknowledged alarms, select All, Acknowledged, or Un-Acknowledged respectively from the Display drop-down list.

    By default, all alarms are displayed.

  3. To see alarms for a particular device, use the standard table search function. See Working with Tables.

    The following example shows the table filtered for the specified IP address:

  4. To see more details on an alarm, select an alarm and then click View.

    The Current Alarm Details window appears:

    The Probable Cause field indicates the direction in which the problem is likely occurring and the possible location of the problem. For example, the Probable Cause field in the above Loss of Signal alarm indicates that the Loss of Signal is in the receive direction and that the device at the far end of the fiber is where you should start troubleshooting.

  5. To acknowledge or unacknowledge an alarm, see Acknowledging or Unacknowledging an Alarm.
  6. To sort, filter, copy, print, or save table entries, see Working with Tables.

Acknowledging or Unacknowledging an Alarm

Use this procedure to acknowledge or unacknowledge an alarm.

You can use alarm acknowledgment in different ways, but typical usage is for you to use alarm acknowledgment to distinguish between alarms that someone is addressing (acknowledged) and alarms that still require someone to examine and triage (unacknowledged).

The color of the acknowledged alarm turns gray to reduce its visual impact and to allow you and other users to focus on the alarms that still need to be examined and assigned.

Acknowledging an alarm does the following:

  • the alarm turns gray in the Current Alarms table

  • the alarm is removed from consideration when determining the alarm indication color to display in the icon in the Network Map

Note

Acknowledging an alarm does not change the severity of the alarm, nor does it change the alarm count for that severity. For example, if there are ten critical alarms and you acknowledge one of them, the acknowledged alarm count increases by one and the critical alarm count remains at ten.

  1. Click the Monitor tab and then select Alarms>Current from the left-nav bar.

    The Current Alarms table is displayed.

  2. To acknowledge an alarm, select an alarm and click Acknowledge.

    The alarm is acknowledged and the alarm row turns gray.

  3. To unacknowledge an acknowledged alarm, select an alarm that has been acknowledged and click Un-acknowledge.

    The alarm is unacknowledged and the alarm row turns back to the color of its severity.
