About the Dashboard
The dashboard is the home page of the administration site and provides several parameters and graphs key monitoring features.
The dashboard includes the following sections:
-
System Monitor—Displays the system status and timestamp and includes the following subsections:
-
Meetings and Users—Status of meetings in progress and usage. Displays the number of meetings currently in progress and the number of unique participants (usage). The status mark indicates whether the meetings in progress and usage are under or over the configured alarm threshold. A green status mark indicates that the system is under a configured threshold. A red status mark indicates that the system is over a configured threshold. See Viewing and Editing Alarms for more information.
-
Alarm icon—Select the Alarm icon to view and edit the alarm threshold settings. Alarm thresholds appear on the Alarms page in numerical form. By default, alarm thresholds appear as a percentage. See Viewing and Editing Alarms for more information about configuring alarms.
You can configure alarms for the following:
-
Meetings In Progress—the current meetings that are experiencing issues.
-
Usage—the total number of distinct users using the system. Occasionally participants are in multiple sessions, but participants are only counted once.
-
Storage—the amount of space used for storing avatar images, meeting recordings, and database backups. The storage alarm appears only if you have configured a storage server. See Adding an NFS or SSH Storage Server for more information. The system disables meeting recording if the storage usage is over the configured threshold.
-
Log Partition—the amount of space used to store the Application Audit Log. If an Auditor is configured for your system, this alarm is only visible to the Auditor.
-
License Usage—the percentage of permanent licenses assigned to host users.
-
Grace Licenses—the number of grace host licenses that are assigned to users.
-
-
-
Data Center—lists the name of each data center, whether Maintenance Mode is on or off, the amount of storage used for each data center, and the status of data replication. See About the Data Center Information Displayed on the Dashboard for more details.
-
Meeting Trend—graph of the number of meetings held on the system during a specified time. Use the From and To fields to set the time for the meeting trend information and for the meetings displayed in the Meetings list. You can select a point on the Meeting Trend graph to list the meetings that occurred during the time specified on the graph. To view meetings that occurred during a specific time of day, mouse over the graph and select the desired time.
-
Meeting Search—finds a meeting by entering specific search criteria, such as the meeting number, meeting topic, or a date range.
-
Meetings—the total number of meetings that occurred during the selected time, the meeting topics, hosts, numbers of participants, and the state of the meeting. If a data point is not selected from the Meeting Trend graph, all meetings for the time period appear. You can sort each column of information in the Meetings list, and the meetings appear in order by state: In progress, Ended, and Not started.
Select a Meeting Topic from the list to display details about the meeting. Details include: the meeting number, start time, end time, general status, and whether the meeting has been analyzed in detail. Before the analysis, the Status parameter shows the overall status of the meeting as it relates to quality. Select Analyze Meeting Detail to perform a detailed analysis of the meeting and generate a log. After the log is compiled, the general Status of the meeting changes, based on the details gathered during the analysis. The system generates and displays the date and time log, and then sends you an email with the log file download information. You can also download the log from the dashboard by selecting Download Log.
Note
If the meeting host doesn't attend the meeting, the system terminates the meeting 30 minutes after the last participant exits the meeting. The meeting ends regardless of the scheduled end time. The meeting shows as being in progress until this time expires.
-
Maintenance—schedules an announcement indicating when Maintenance Mode will be turned on or off. See Scheduling a Maintenance Window and About Maintenance Mode for more information.
-
Last System Backup—appears if you have configured a storage server. It notifies you if the backup failed and the date of the first backup attempt if one has not yet been created. A link to the backup is provided for each data center. The window shows:
-
Time and date that the last backup was created.
-
Filename.
-
File size.
-
Location of the backup.
-
Date and time of the next backup.
-
Link to configure the system backup.
-
-
Users—displays the number of active users, whether Directory Integration is configured, the time of the next synchronization (if configured), and the selected type of authentication. Select View More to go to Editing Users.
-
Settings—Shows the maximum number of participants allowed in each meeting, audio type, and whether Webex HQ video is enabled. Select View More to go to Configuring Settings.
About the Data Center Information Displayed on the Dashboard
The System Monitor section of the dashboard displays status information for the data centers that comprise your system. If you have a single data center system, the data center name automatically assigned by the system is CWMS System, but the status information is dynamically updated for the single data center. In a multi-data center system, each data center is listed in a separate row by the name you entered during the join data center process and the status information is dynamically updated separately and displayed for each data center.
-
Status—This column displays the status of each data center. Status can be Good, Partial Service, Blocked, or Down. -
Good—All components of the data center are working properly. No system-generated email messages sent to the administrator.
-
Partial Service—Some of the components of the data center are not working properly, but the data center is providing service. The system sends an email to the administrator indicating that this data center needs attention.
-
Blocked—The system has blocked service on this data center and is redirecting all activity to another data center. The system sends an email to the administrator to indicate that service is down, data is being redirected to another data center, and this data center needs attention.
-
Down—The operation of a data center has degraded to the point where it can no longer provide reliable service and failover to an operational data center is in progress. The system sends an email to the administrator to indicate that service is down, data is being redirected to another data center, and this data center needs attention.
In a Multi-data Center (MDC) environment, some components are capable of cascading, so the disabled service on this data center might be provided by another data center. This is not an indication of overall system status; it applies only to the status of this data center.
-
Blocked or Down and Maintenance Mode is on—The data center status continues to show that the data center is blocked. When Maintenance Mode is turned off AND all components are again up and running, the status changes.
-
Unreachable—Another data centers cannot communicate with this data center. The system sends an email to the administrator asking them to check the network connectivity between the data centers.
-
-
Maintenance—Indicates whether a data center has Maintenance Mode turned On or Off.
-
Storage—The amount of storage used on the storage server connected to each data center. Not Configured displays If a storage server is not connected to the system.
-
Data Replication—Indicates whether data replication is occurring between the data centers in an MDC system.
When a data center is in the Blocked or Down state, users might experience the following:
-
In-progress meetings are automatically moved to an operational data center after a few minutes; similar to what happens in a failover situation. There is no impact on PCN or Blast Dial meetings.
-
Previously scheduled meetings that have not started move to the operational data center. No other actions are required for the host or participants.
-
Users sign in to a Webex site URL in the usual manner, but the system redirects the sign-in to the operational data center.
-
Administrators can sign in to the blocked data center as well as the operational data center.
-
Administrators receive a system-generated email which explains which data center is in the blocked state, and information explaining some of the possible causes.
Monitoring CPU, Memory, and Network Usage
To monitor CPU, memory, and network usage, we recommended that you use the performance tab of each CWMS virtual machine in vSphere client or vSphere Web client. The advantage to monitoring performance a of CWMS virtual machines by using vSphere client or vSphere Web client is that each virtual machine can be monitored separately and for a specified period of time. If an issue that affects the system negatively exists, it is easier to precisely troubleshoot.
To monitor CPU usage refer to http://pubs.vmware.com/vsphere-51/index.jsp?topic=%2Fcom.vmware.vsphere.monitoring.doc%2FGUID-FC93B6FD-DCA7-4513-A45E-660ECAC54817.html. Variations and spikes in CPU usage is expected; however, during general system use all levels should be less than 90 percent.
To monitor Memory usage refer to http://pubs.vmware.com/vsphere-51/index.jsp#com.vmware.vsphere.monitoring.doc/GUID-C442423F-18CD-4F01-914E-286ED6C72BC6.html. During normal operation Memory usage should be stable. Some variations are expected, but an increasing trend over a long period of time might indicate a pending issue that will soon affect system performance.
To monitor Network usage refer to http://pubs.vmware.com/vsphere-51/index.jsp#com.vmware.vsphere.monitoring.doc/GUID-41B7E742-B387-4638-A150-CB58E2ADD89F.html. Network usage can vary widely in reference to a CWMS virtual machine, and spikes in network usage (for example during a backup) are expected.
