Monitoring the Status of Server

This topic introduces how you can use Server Monitor to inspect the status of Logi Report Server, including Servers in a cluster, reports, online users, and the database connection pool.

In Server Monitor, 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 view the status of these reports.

Note icon Server Monitor is not able to monitor the information of a report that is running in Page Report Studio.

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.

To export the monitoring data of the reports' status:

Select the Export Data link on the reports status panel. Monitor displays the Export Data dialog box.
From the Report drop-down list, select he type of reports you want to export the monitoring data.
Select the Calendar icon on the right of the From text box to select the date and time from which the monitoring data starts. You can also type the value in the text box.
Select the Calendar icon on the right of the To text box to select the date and time to which the monitoring data ends. You can also type the value in the text box.
In the File Name text box, type the name of the exported file.
Select OK to export the data to a CSV file. Monitor displays the File Download panel. You can choose to open the file or save it elsewhere.

Logi Report encodes the exported monitoring data in the CSV file with UTF-8. If you open an exported CSV file that contains Chinese strings by a double-click, the Chinese strings display as random code in the file. To solve this problem, open the file in the following way:

Start Microsoft Excel first.
Select From Text in the Data tab.
Select the exported CSV file.
Select Import.
Select 65001: Unicode (UTF-8) in the File Origin selector.
Keep selecting Next.
Select Finish.
Select OK.

Monitoring the Status of Online Users

Expand any Server node in the left panel of the Server Monitor home page, then select Users, and you can see the status of the online users on the Server. 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 who logged onto the Server.
Create Time	The time when the user session was created.
Last Access Time	The time when the user last accessed the Server.
HTTP Session ID	The session ID in the HTTP service.
Authentication	The authentication type. It can be Internal or External.

Monitoring the Status of the Database Connection Pool

Expand any Server node in the left panel of the Server Monitor home page, then select Databases, and you can see the status of the Server's database connection pool. 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	The URL connecting to a database.	The connections that are based on the URL to catch in the pool.
Expiring Time(s)	0 (the default value) or expiring time in seconds. If the value is zero, then the connection never expires.	The time during which a connection can be alive. If a connection has expired, the connection pool closes it.
Idle Expiring Time(s)	1 (the default value) or expiring time in seconds. Its value must be larger than or equals to 1.	The time during which a connection is kept after it starts idling. If a connection is not used, it stays open until the idle expiry time has reached.
Maximal Connection Count	0 (the default value) or a positive integer.	The pool size which limits the number of connections under a single URL.
Maximal Share Count	0 (the default value) or a positive integer.	The number of users who can share a connection simultaneously.
Attempt	A positive integer. The default value is 1.	The number of attempts for recreating a connection when the connection pool has failed to create one.
Interval(ms)	0 (the default value) or a positive integer in milliseconds.	If the property Attempt is larger than 1, then the connection pool waits for an interval time before it retries to create a connection. This property defines the interval time.
Last User Connecting Time(s)	0 (the default value) or a positive integer in seconds.	The time elapsed since the last user took this connection.
Current Idle Time(s)	0 (the default value) or a positive integer in seconds.	The time elapsed since the connection started to idle.
Current Share Count	0 (the default value) or a positive integer.	The number of users who are currently sharing this connection.

You can set the properties numbered 2 to 8 in the ConnectionPoolConfig.properties file in <server_install_root>\bin, and Server displays the last three properties according to the real time status.
