Monitoring the Server Status

Logi JReport Server Monitor allows you to inspect the status of Logi JReport Server. You can list the servers and their status from a cluster. You can also list the reports by drilling down into the servers, for example, running reports, waiting reports, finished reports, and failed reports. Tracking further down, you can even view the status of these reports. However, Logi JReport Server Monitor is not able to monitor the information of a report that is running in Page Report Studio.

Below is a list of the sections covered in this topic:

Exporting the Monitoring Data

You can export the monitoring data of the reports' status to a CSV file. However, before doing this, you need to make sure the profiling DB on the server node where the monitoring data will be saved has already been configured. For details about how to configure the profiling DB, see the topic Configuring in a Standalone Environment.

To export the monitoring data of the reports' status:

Select the Export Data link in the report status panel. The Export Data dialog appears.
Specify the report type, the time period of the monitoring data and the name of the exported file respectively.
Select OK to export the data.

The following are details about options in the Export Data dialog:

Report

The type of reports you want to export the monitoring data.

From

The date and time from which the monitoring data starts. You can type it in the text box or select the calendar button to select the date and time.

The date and time to which the monitoring data ends. You can type it in the text box or select the calendar button to select the date and time.

File Name

The name of the exported file.

Exports the data to a CSV file and opens the File Download panel. You can choose to open the file or save it elsewhere.

Cancel

Does not retain any changes and closes the dialog.

Note: The exported monitoring data in the CSV file are encoded with UTF-8. If you open an exported CSV file which contains Chinese strings by a double-click, the Chinese strings would be displayed as random code in the file. To solve this problem, you need to open the file in the following way:

Start Microsoft Excel first.
Select From Text in the Data tab, then select the exported CSV file and select Import.
Select 65001: Unicode (UTF-8) in the File Origin selector, then keep selecting Next and at last select Finish and OK.

Monitoring the Status of Online Users

To see the status of the online users, expand any server node in the left panel of the Logi JReport Server Monitor home page, and then select Users. You can also select and remove specific users.

The status table of the online users includes:

Column	Description
Session ID	The internal ID of the user session.
User ID	The ID of the user logged onto the server.

Monitoring the Status of the Database Connection Pool

To see the status of the database connection pool, expand any server node in the left panel of the Logi JReport Server Monitor home page, and then select Databases. You can also select and remove specific connections.

The status table of the connection pool includes:

Column	Value	Description
User	String	The user who is currently using the connection.
URL	A URL connecting to a database.	It specifies the connections that are based on a URL which will be caught in the pool.
Expiring Time(s)	0 (default) or expiring time. The unit is second. If the value is zero then the connection will never expire.	Shows the time during which a connection can be alive. If a connection has expired, the connection pool will close it.
Idle Expiring Time(s)	1 (default) or expiring time. The unit is second. Its value must be larger than or equals to 1.	Shows the time during which a connection is kept after it starts idling. If a connection is not used, it will stay open until the idle expiry time has been reached.
Maximal Connection Count	0 (default) or a positive integer.	Shows the pool size, which limits the number of connections under a single URL
Maximal Share Count	0 (default) or a positive integer.	Shows the number of users who can share a connection simultaneously.
Attempt	A positive integer, the default value is 1.	Shows whether to re-create a connection when the connection pool has failed to create one and the number of attempts for creating the connection. If the user sets this value to a non-positive integer, the default value (1) will be used.
Interval(ms)	0 (default) or a positive integer. The unit is millisecond (ms).	If property ‘Attempt' is larger than 1, then before the connection pool retries to create a connection it will wait for an interval time. This property defines the interval time.
Last User Connecting Time(s)	0 (default) or a positive integer. The unit is second.	It shows the time elapsed since the last user has taken this connection.
Current Idle Time(s)	0 (default) or a positive integer.The unit is second.	Shows the time elapsed since the connection started to idle.
