About Alerts
The system generates alert messages to notify administrator when a predefined condition is met, such as when an activated service goes from up to down. Alerts can be sent out as email/epage.
RTMT, which supports alert defining, setting, and viewing, contains preconfigured and user-defined alerts. Although you can perform configuration tasks for both types, you cannot delete preconfigured alerts (whereas you can add and delete user-defined alerts).
The Alert menu comprises the following menu options:
•Alert Central—This option comprises the history and current status of every alert in the system.
Note You can also access Alert Central by clicking the Alert Central icon in the hierarchy tree in the system drawer.
•Set Alert/Properties—This menu option allows you to set alerts and alert properties.
•Remove Alert—This menu category allows you to remove an alert.
•Enable Alert—With this menu category, you can enable alerts.
•Disable Alert—You can disable an alert with this category.
•Suspend cluster/node Alerts—This menu category allows you to temporarily suspend alerts on a particular Cisco Unified Presence node or on the entire cluster.
•Clear Alerts—This menu category allows you to reset an alert (change the color of an alert item from to black) to signal that an alert has been taken care of. After an alert has been raised, its color will automatically change to in RTMT and will stay that way until you manually clear the alert.
•Clear All Alerts—This menu category allows you to clear all alerts.
•Alert Detail—This menu category provides detailed information on alert events.
•Config Email Server—In this category, you can configure your email server to enable alerts.
•Config Alert Action—This category allows you to set actions to take for specific alerts; you can configure the actions to send the alerts to desired email recipients.
In RTMT, you configure alert notification for perfmon counter value thresholds and set alert properties for the alert, such as the threshold, duration, frequency, and so on.
You can locate Alert Central under the Tools hierarchy tree in the quick launch. Alert Central provides both the current status and the history of all the alerts in the system.

Preconfigured Alerts
You can enable or disable preconfigured and custom alerts in Alert Central; however, you cannot delete preconfigured alerts.
The following list comprises the preconfigured alerts for the system:
•AuthenticationFailed
•CiscoDRFFailure
•CoreDumpFileFound
•CpuPegging
•CriticalServiceDown
Note The CriticalServiceDown alert only generates when the service status equals down (not for other states).
•HardwareFailure
•LogFileSearchStringFound
•LogPartitionHighWaterMarkExceeded
•LogPartitionLowWaterMarkExceeded
•LowActivePartitionAvailableDiskSpace
•LowAvailableVirtualMemory
•LowInactivePartitionAvailableDiskSpace
•LowSwapPartitionAvailableDiskSpace
•ServerDown
Note The ServerDown alert generates when the currently "active" AMC (primary AMC or the backup AMC, when the primary is not available) cannot reach another node in a cluster. This alert identifies network connectivity issues in addition to a server down condition.
•SparePartitionLowWaterMarkExceeded
•SparePartitionHighWaterMarkExceeded
•SyslogSeverityMatchFound
•SyslogStringMatchFound
•SystemVersionMismatched
•TotalProcessesAndThreadExceededThreshold
Alert Fields
You can configure both preconfigured and user-defined alerts in RTMT. You can also disable both preconfigured and user-defined alerts in RTMT. You can add and delete user-defined alerts in the performance-monitoring window; however, you cannot delete preconfigured alerts.

Alert Logs
The alert log stores the alert, which is also stored in memory. The memory is cleared at a constant interval, leaving the last 30 minutes of data in the memory. When the service starts/restarts, the last 30 minutes of the alert data load into the memory by the system reading from the alert logs that exist in all servers in the cluster.The alert data in the memory is sent to the RTMT clients on request.
Upon RTMT startup, RTMT shows all logs that occurred in the last 30 minutes in the Alert Central log history. The alert log periodically updates, and new logs are inserted into the log history window. After the number of logs reaches 100, RTMT removes the oldest 40 logs.
The following file name format for the alert log applies: AlertLog_MM_DD_YYYY_hh_mm.csv.
The alert log includes the following attributes:
•Time Stamp—Time when RTMT logs the data
•Alert Name—Descriptive name of the alert
•Node—Node name for where RTMT raised the alert
•Alert Message—Detailed description about the alert
•Description—Description of the monitored object
•Severity—Severity of the alert
•PollValue—Value of the monitored object where the alert condition occurred
•Action—Alert action taken
•Group ID—Identifies the source of the alert
The first line of each log file comprises the header. Details of each alert get written in a single line, separated by a comma.

Suspending Alerts on Cisco Unified Presence Nodes or the Cluster
You may want to temporarily suspend some or all alerts, either on a particular Cisco Unified Presence node or the entire cluster. For example, if you are upgrading the Cisco Unified Presence to a newer release, you would probably want to suspend all alerts until the upgrade completes, to ensure you do not receive emails or epages during the upgrade.
Procedure
Step 1 Select System > Tools > Alert > Suspend Cluster/Node Alerts.
Step 2 Perform one of the following actions:
|
If you want to:
|
Action
|
Suspend all alerts in the cluster |
a. Click Cluster Wide. b. Check Suspend all alerts. c. Click OK. |
Suspend alerts per server |
a. Click Per Server. b. Check Suspend for each server on which you want alerts to be suspended. c. Click OK. |
Resume alerts |

Troubleshooting Tips
Per server suspend states do not apply to Cisco Unified Presence clusterwide alerts.
Configuring Log Partition Monitoring
Log Partition Monitoring, which is installed automatically with the system, uses configurable thresholds to monitor the disk usage of the log partition on a server. The Cisco Log Partitioning Monitoring Tool service starts automatically after installation of Cisco Unified Presence. The Cisco Log Partitioning Monitoring Tool service starts automatically after installation of Cisco Unity.
Every 5 minutes, Log Partition Monitoring uses the following configured thresholds to monitor the disk usage of the log partition on a server:
•LogPartitionLowWaterMarkExceeded (% disk space)—When the disk usage is above the percentage that you specify, LPM sends out an alarm message to syslog and an alert to RTMT Alert central. To save the log files and regain disk space, you can use trace and log central option in RTMT.
•LogPartitionHighWaterMarkExceeded (% disk space)—When the disk usage is above the percentage that you specify, LPM sends a n alarm message to syslog and an alert to RTMT Alert central.
In addition, Cisco Log Partitioning Monitoring Tool service checks the server every 5 seconds for newly created core dump files. If there are new core dump files, Cisco Log Partitioning Monitoring Tool service sends a CoreDumpFileFound alarm and an alert to Alert Central with information on each new core file.
When the log partition monitoring services starts at system startup, the service checks the current disk space utilization. If the percentage of disk usage is above the low water mark, but less than the high water mark, the service sends a alarm message to syslog and generates a corresponding alert in RTMT Alert central.
To configure Log Partitioning Monitoring, set the alert properties for the LogPartitionLowWaterMarkExceeded and LogPartitionHighWaterMarkExceeded alerts in Alert Central.
To offload the log files and regain disk space on the server, you should collect the traces that you are interested in saving by using the Real-Time Monitoring tool.
If the percentage of disk usage is above the high water mark that you configured, the system sends an alarm message to syslog, generates a corresponding alert in RTMT Alert Central, and automatically purges log files until the value reaches the low water mark.
Note Log Partition Monitoring automatically identifies the common partition that contains an active directory and inactive directory. The active directory contains the log files for the current version of Cisco Unified Presence, and the inactive directory contains the log files for the previous installed version of Cisco Unified Presence. The active directory contains the log files for the current version of Cisco Unity, and the inactive directory contains the log files for the previous installed version of Cisco Unity. If necessary, the service deletes log files in the inactive directory first. The service then deletes log files in the active directory, starting with the oldest log file for every application until the disk space percentage drops below the configured low water mark. The service does not send an email when log partition monitoring purges the log files.
After the system determines the disk usage and performs the necessary tasks (sending alarms, generating alerts, or purging logs), log partition monitoring occurs at regular 5 minute intervals.
Before You Begin
To utilize log partition monitor, verify that the Cisco Log Partitioning Monitoring Tool service, a network service, is running on the server on Cisco Unified Serviceability. Stopping the service causes a loss of feature functionality.
.Procedure
Step 1 Select Tools > Control Center > Network Services.
Step 2 Select the server where you want to monitor the disk usage from the Servers list box.
Step 3 Click Go.
Step 4 Verify the status of the Cisco Log Partition Monitoring Tool (LPM) under Performance and Monitoring Services.
Step 5 Click the radio button next to Cisco LPM If the LPM is not running.
Step 6 Click Start.
