TCS Alarms

May 12, 2023 19:20

Selecting Alarms in the navigation pane opens the Alarms dashboard. TCS stores alarm information for up to three months.

As with other navigation pane windows, begin by ensuring that the correct network entity has been chosen from the drop-down menus at the top. This filters the network down to the granularity needed. Because the menus are hierarchical, start by selecting the Region, then Market, Site, Cell, and Sector as needed. Use the search bar on the top left to search or filter the list results based on attributes such as serial number or hostname. Note: In the example below, only alarms for the sector (BN) named North BN are shown.

A ribbon at the top of the alarm dashboard contains high-level information and shortcuts to specific data (filters). The left-hand side of the section (gray) displays a summary of alarms. The bar graph shows the number of alarms raised for BNs, RNs and TCS. Clicking BN, RN, or TCS filters the list to only alarms on those devices. The colored circles indicate the criticality of those alarms: Critical (red), Major (orange), and Minor (yellow). The number in each circle indicates the number of alarms that meet this criterion. Clicking a circle filters the list to only alarms that meet the specified level. In the example below, the image on the left in the gray box indicates that there is a total of 1 alarm for BNs, 29 for RNs, and none for TCS. The alarms shown are filtered to show only alarms in sector North BN that are on a BN.

The right-hand side of the ribbon (green) breaks down alarms by type. Clicking each type automatically filters the displayed list. Alarm types include:

Operational: Error in system operations, e.g., RN is unable to reach BN, high CPU utilization, low disk space, no GPS update, timing error, firmware error.
Communication: Error in communication, e.g., network interface down, unable to get DHCP address (if enabled), IP address conflict, unable to resolve hostname (DNS failure).
Equipment: Hardware error, e.g., temperature is not within thresholds.
Other: Any alarms that are not otherwise classified.
Processing: Error in system processing, e.g., configuration update failure.
Environmental: Issues with operational environment, e.g., number of GPS satellites available for GPS is low.

In the example below, the alarms shown are filtered to show only alarms in North BN that are either a communication or equipment alarm on a BN and only of major criticality.

The Customize icon on the lower right can be used to modify which fields are displayed. Options include:

Serial Number: The device serial number
Hostname: The device hostname
Name: The name of the alarm
Raised Time: The time the alarm was created
Severity: The severity of the alarm (WARNING, MINOR, MAJOR, CRITICAL)
Type: The alarm type
Raise Count: The number of times this alarm has been raised
Current Value: The current value from the last alarm as applicable, e.g., if a CPU utilization alarm is raised and the associated value is 60%, the current value will reflect the 60%.
Resource: The source of the alarm within the system
Description: A brief description of the alarm

Alarms are not automatically refreshed. To change this behavior, click Auto-Refresh on the lower side of the screen.

Note: Both the customization and auto refresh changes are persistent for the user account and the new settings will be maintained even after logging out.

Click the column names to sort the alarm list by that column’s values in either descending or ascending order. Click Download in the bottom left of the screen to download a comma separated (CSV) list of all displayed alarms (meaning the saved file content is filter sensitive).
