Dashboard

After you log into the CTRS Administrative UI, the Troubleshoot > Dashboard page appears. You can also access this page by clicking Dashboard in the left navigation.

As shown in Figure 6-1, the Troubleshoot > Dashboard page enables you to view high-level reports on the following aspects of the CTRS:

•Disk usage for media storage

•Users

•Recordings

•Time

•Services

Figure 6-1 Troubleshoot > Dashboard

Table 6-1 describes each Dashboard field. Each field name or entry is a link, which you can click to get more detailed information.

You can refresh the data in the Dashboard at any time by clicking the refresh icon in the upper right corner of the page.

Time
System Time	Displays the time determined by the value of the set timezone command in the CTRS command-line interface (CLI). (The default value of this command is Greenwich Mean Time (GMT)/Coordinated Universal Time (UTC)). This time typically corresponds to the location of the server running the CTRS application.
Local Time	Displays the time determined by the value of the Time Zone field, which you can access by clicking Preferences in the upper right corner of the CTRS Administrative UI. This time typically corresponds to the location of the CTRS administrator.
Services

The status can be one of the following: •OK—The CTRS is registered with a particular server, and the connection to the server is operational. •Error—The CTRS is registered with a particular server, but the connection to the server is not operational. •NA—You cannot register this version of CTRS with CTS-Manager. Only the Commercial Express version of CTRS can be registered with CTS-Manager. For more information on a particular server, click the link to access the respective server page in the CTRS Administrative UI.

CTRS Alarms and System Errors Messages

You can view CTRS system messages in one of two ways:

•Click System Messages in the left navigation (see Figure 6-6). The System Messages page displays a list of messages.

Figure 6-6 Troubleshoot > System Messages

•From System Status at the bottom of the left navigation, click the icon for Warnings or Errors.

	If you click the icon for Warnings, you will see endpoint alert information. Warnings are issued every 20 seconds when an endpoint crosses its packet loss threshold. If congestion continues for more than 40 seconds, the endpoint will be dropped.
	If you click the icon for Errors, you will see endpoint drop information. Whenever an endpoint drops from high packet loss, an error is issued with the error code "CONGESTION."

The following table provides field descriptions for all system error and warning displays:

Table 6-4 System Error Field Descriptions

Field	Description
Time	Displays the time at which the condition occurred.
Severity	Indicates the severity level of the error. There are eight severity levels as follows: •Emergency •Alert •Critical •Error •Warning •Notice •Info •Debug
Summary	Message describing the error.
Recommendation	Recommended action to deal with the condition.

•To delete one of the system error messages, click the radio button to the left of the table entry, and then click Clear.

•To delete all error messages displayed, click Clear All.

Log Files

Click Log Files in the left menu to display or modify log information (see Figure 6-7).

Figure 6-7 Troubleshoot > Log Files

Use the Log File page to set severity levels for alarms associated with specific system processes, to filter log files displayed, and to download log files.

Configuring the Severity Level of System Error Messages

To configure the severity level of system level error messages and alarms for specific process areas:

---

Step 1 Click Log Files under Troubleshooting in the left menu to access the Log Files page.

Step 2 At the top of the Log Files page, there is a table listing the following CTRS system processes:

•CCS

•Post Processor

•Execution Manager

•Media Processor

•Key Exchange

•Transcode Processor

To the right of each process is a drop-down menu with these severity levels:

•CRIT

•DEBUG

•ERROR

•INFO

•OFF

•WARN

Click the down arrow to display the defined levels of severity. Choose the level at which logs are captured.

---

Note Log levels create varying amounts of data; for example, DEBUG creates more log entries than CRIT. Because verbose logs can impact system performance, use verbose logs only to track a problem.

---

---

Filtering the Log File Table Listings

To filter the log files displayed in the Log File Table:

---

Step 1 Click Log Files under Troubleshooting in the left menu to access the Log Files page.

Step 2 Click the down arrow to the right of Processes to display a list of CTRS processes. Click a specific process on which to filter log files. Choices are the following:

•All

•Alarm-Logs

•CCS

•CDR-Logs

•Core

•CTRS-Sysop

•Exe-Exchange

•Media-Processor

•Post-Process

•SIP

•Web-UI

Downloading Log Files

To download log files from the Log File table:

---

Step 1 Click Log Files under Troubleshooting in the left navigation.

Step 2 At the bottom of the Log Files page is the Log File list. The table is organized as described in Table 6-5.
