8 Monitoring and Reporting in ACS Configuring Tabs in the Dashboard
1 Cisco Systems, Inc.www.cisco.com Managing Alarms The Monitoring feature in ACS generates alarms to notify you of critical system conditions. The monitoring component retrieves data from ACS. You can configure thresholds and rules on this data to manage alarms. Alarm notifications are displayed in the web interface and you can get a notification of events through e-mail and Syslog messages. ACS filters duplicate alarms by default. This chapter contains the following sections: Understanding Alarms, page 1 Viewing and Editing Alarms in Your Inbox, page 3 Understanding Alarm Schedules, page 8 Creating, Editing, and Duplicating Alarm Thresholds, page 10 Deleting Alarm Thresholds, page 36 Configuring System Alarm Settings, page 36 Understanding Alarm Syslog Targets, page 37 Understanding Alarms There are two types of alarms in ACS: Threshold Alarms, page 1 System Alarms, page 1 Threshold Alarms Threshold alarms are defined on log data collected from ACS servers that notify you of certain events. For example, you can configure threshold alarms to notify you of ACS system health, ACS process status, authentication activity or inactivity, and so on. You define threshold conditions on these data sets. When a threshold condition is met, an alarm is triggered. While defining the threshold, you also define when the threshold should be applied (the time period), the severity of the alarm, and how the notifications should be sent. Fifteen categories of available alarm thresholds allow you to monitor many different facets of ACS system behavior. See Creating, Editing, and Duplicating Alarm Thresholds, page 10 for more information on threshold alarms. System Alarms System alarms notify you of critical conditions encountered during the execution of the ACS Monitoring and Reporting viewer. System alarms also provide informational status of system activities, such as data purge events or failure of the log collector to populate the View database. You cannot configure system alarms, which are predefined. However, you do have the option to disable system alarms or decide how you want to be notified if you have enabled them.
2 Managing Alarms Understanding Alarms This section contains the following topics: Evaluating Alarm Thresholds, page 2 Notifying Users of Events, page 2 Evaluating Alarm Thresholds ACS evaluates the threshold conditions based on a schedule. You define these schedules and, while creating a threshold, you assign a schedule to it. A schedule consists of one or more continuous or noncontinuous periods of time during the week. For example, you can create a schedule that is active from 8:00 a.m. to 5:00 p.m., Monday through Friday. See Understanding Alarm Schedules, page 8 for more information. When you assign this schedule to a threshold, ACS evaluates the threshold and generates alarms only during the active period. ACS evaluates the thresholds periodically depending on the number of thresholds that are currently enabled. Table 111 on page 2 provides the length of the evaluation cycle for a given number of thresholds. When an evaluation cycle begins, ACS evaluates each enabled threshold one after another. If the schedule associated with the threshold allows the threshold to be executed, ACS evaluates the threshold conditions. An alarm is triggered if the condition is met. See Creating, Editing, and Duplicating Alarm Thresholds, page 10 for more information. Note: System alarms do not have an associated schedule and are sent immediately after they occur. You can only enable or disable system alarms as a whole. Notifying Users of Events When a threshold is reached or a system alarm is generated, the alarm appears in the Alarms Inbox of the web interface. From this page, you can view the alarm details, add a comment about the alarm, and change its status to indicate that it is Acknowledged or Closed. The alarm details in this page, wherever applicable, include one or more links to the relevant reports to help you investigate the event that triggered the alarm. The Dashboard also displays the five most recent alarms. Alarms that you acknowledge or close are removed from this list in the Dashboard. ACS provides you the option to receive notifications in the following formats: E-mail—Contains all the information that is present in the alarm details page. You can configure a list of recipients to whom this e-mail must be sent. ACS 5.7 provides you the option to receive notification of events through e-mail in HTML format. Syslog message—Sent to the Linux or Windows machines that you have configured as alarm syslog targets. You can configure up to two alarm syslog targets. Table 111 Evaluation Cycle of Alarm Thresholds Number of Enabled Thresholds Evaluation Cycle1 1. If the time taken to evaluate the thresholds increase, then the evaluation cycle increases from 2 to 3 minutes, 3 to 5 minutes, and from 5 to 15 minutes. The evaluation cycle time is reset to 2, 3, and 5 minutes every 12 hours. 1 to 20 Every 2 minutes 21 to 50 Every 3 minutes 51 to 100 Every 5 minutes
3 Managing Alarms Viewing and Editing Alarms in Your Inbox Viewing and Editing Alarms in Your Inbox You can view alarms that ACS generates based on a threshold configuration or a rule on a set of data collected from ACS servers. Alarms that have met the configured thresholds are sent to you r i nb ox. After you view an alarm, you can edi t the status of the alarm, assign the alarm to an administrator, and add notes to track the event. To view an alarm in your Inbox, select Monitoring and Reports > Alarms > Inbox. The Inbox page appears with a list of alarms that ACS triggered. Table 112 on page 3 describes the fields on the Alarms page. Table 113 on page 4 lists the system alarms in ACS 5.7 and its severity. Table 112 Alarms Page Option Description SeverityDisplay only.

7 Managing Alarms Viewing and Editing Alarms in Your Inbox Note: The Alarm for ACS database exceeding the quota is sent only when the total size of the ACS database exceeds the quota. Total size of ACS database = acs*.log + acs.db where acs*.log is the ACS database log file. Both the acs*.log and acs.db files are present under /opt/CSCOacs/db. Note: ACS cannot be used as a remote syslog server. But, you can use an external server as a syslog server. If you use an external server as a syslog server, no alarms can be generated in the ACS view as the syslog messages are sent to the external syslog server. If you want to generate the alarms in ACS view, set the logging option as localhost using CLI. To edit an alarm: 1.Select Monitoring and Reports > Alarms > Inbox. The Inbox page appears with a list of alarms that ACS triggered. 2.Check the check box the alarm that you want to edit and click Edit.

You can create, edit, and delete alarm schedules. You can create alarm schedules to be run at different times of the day during the course of a seven-day week.
