Monitor Server Activity

To monitor and manage a variety of aspects of server activity, press the ‘Monitoring’ button gauge at the top of Enterprise Manager.

Monitoring

On the pages listed in the left panel you can view Dashboards and queries that are currently executing on the server, and can terminate undesired activity. You can also view currently active users, and terminate any undesired sessions.

Summary

In Enterprise Edition, when multi-tenancy is enabled (see Enable Multi-Tenancy), this feature is available to Site Administrators only.

Use the Summary Monitoring page to track server performance. In a clustered environment, select a machine from ‘Cluster Node’ menu to view the monitoring statistics for that machine. Click on a chart to view the detailed information provided by the corresponding ‘Monitoring’ page.

Monitoring Summary

The following information is available. The ‘Level’ column indicates the monitoring level required for the feature. The level is set by the monitor.level property. (See All Properties for information about how to set properties.)

The bottom of the Summary page provides details about the JVM currently being used by the server, including the Java Home Directory and Classpath. If a reverse proxy is in use, this is indicated above the JVM information. If no reverse proxy information appears in that location, this means that no reverse proxy was detected.

Dashboards

Use the Dashboards Monitoring page to access key information about executing Dashboards that are currently being processed by the server, as well as open Dashboards that are active in memory but are not currently being processed.

In a clustered environment, select a machine from ‘Cluster Node’ menu to view the monitoring statistics for that machine.

Monitoring Viewsheets

The page provides the following information:

Name

The name of the Dashboard.

User

The user who opened the Dashboard.

Task

Scheduled task executing Dashboard.

Age

The time elapsed since the Dashboard was opened.

To terminate a Dashboard, press the ‘Select’ box select empty next to the Dashboard, and then press the Remove button below the table.

  • For an executing Dashboard, Remove terminates execution, and removes any cached data.

  • For an open Dashboard, Remove deletes any cached data.

Queries

Use the Queries Monitoring page to access key information about queries currently executing on the server. In a clustered environment, select a machine from ‘Cluster Node’ menu to view the monitoring statistics for that machine.

Monitoring Queries

The page provides the following information:

Name

The name of the query or the Data Worksheet/data model executing the query.

User

The user who executed the query.

Task

The scheduled task that executed the query.

Thread

The thread within which the query is executing. Click the link to obtain a stack trace.

Asset

The name of the Dashboard from which the query was executed.

Age

The length of time that the query has been executing.

Cache

In Enterprise Edition, when multi-tenancy is enabled (see Enable Multi-Tenancy), this feature is available to Site Administrators only.
Tailor Performance, for information on configuring caching.

Use the Cache Monitoring page to access key information for the data cache. In a clustered environment, select a machine from ‘Cluster Node’ menu to view the monitoring statistics for that machine.

Monitoring Cache

The page provides the following information:

Data Objects

The number of dataset rows cached in memory or disk.

Hits

The number of cache hits. A hit occurs when a query is performed against the cache and a match is found. (Requires the monitor.level property to be set to ‘High’. See All Properties.)

Misses

The number of cache misses. A miss occurs when a query is performed against the cache and no match is found. (Requires the monitor.level property to be set to ‘High’. See All Properties.)

Swapped

The number of bytes swapped from disk to memory, or from memory to disk. (Requires the monitor.level property to be set to ‘Medium’. See All Properties.)

Users

Requires the monitor.level property to be set to ‘High’. See All Properties.

Use the Users Monitoring page to access key information about user logins, and allows you to terminate a given user session. In a clustered environment, select a machine from ‘Cluster Node’ menu to view the monitoring statistics for that machine.

Monitoring Users

The page provides the following information:

Session ID

The unique session identifier.

User

The user who attempted to log in.

Address

The IP address from which the login was attempted.

Age

The elapsed time since start of session.

To terminate a user session, click the ‘Select’ box select empty next to the desired user, and then press the Remove button.

Cluster

This feature is available only in Enterprise Edition.
In Enterprise Edition, when multi-tenancy is enabled (see Enable Multi-Tenancy), this feature is available to Site Administrators only.

Use the Cluster Monitoring page to view cluster nodes.

Logs

In Enterprise Edition, when multi-tenancy is enabled (see Enable Multi-Tenancy), this feature is available to Site Administrators only.
Logging, for information on how to configure logging behavior.

Use the Logs Monitoring page to view and download server and scheduler logs.

Figure 36

To do this follow the steps below:

  1. From the ‘Log file’ menu, select ‘sree.log’ for the InetSoft server log or ‘schedule.log’ for the Scheduler log. This will display the selected log.

    If the log size has exceeded the ‘Maximum Log File Size’ set on the Logging page (see Logging), you will see multiple log files listed.

  2. Select the ‘All’ option to display the entire contents of the log file (maximum 3000 lines by default), or enter the ‘Number of Lines’ from the end of the file to display.

    LogNumberOfLines

  3. Select ‘Enable Auto-refresh’ to allow the display to update automatically as new lines are written to the log.

  4. To download a zip archive containing all log files, press the Download button at the top of the page.

    LogDownload

  5. To refresh the display with current log records, press the Refresh button (only available when ‘Enable Auto-refresh’ is disabled).

  6. To start a new log file, press the Rotate button. This saves the current log file under an automatically-generated name such as sree-IP_Address-index.log. or schedule-IP_Address-index.log, and begins adding log records to a new log file.

These log monitoring settings are not retained following a server restart.
