  The left part of the Monitor Servers window lists all available servers.

The right part of the window shows details about one or more selected servers. If all the available servers are working within the required parameters, this overview is hidden. If one or more servers are in warning state, the overview for these servers will open automatically.

To view server details

• Double-click the server in the Overview panel, or

• Alternatively, right-click the server, and select Open Overview

• Select Open All Overviews to show details of all available servers.

Overview

The Overview frame shows a quick overview of all the parameters. A green light next to the parameter indicates that all systems are normal. A yellow light indicates that there are non-critical problems. A red light indicates that system limitations have been reached or there are serious errors.

The overview shows this basic information for the following parameters:

• License

• Disk

• Memory

• Health

• Cluster

• Activity

License

The License frame shows the status of the Graphic Hub license.

The status shows license limitations or remaining number of days until the license expires. If your license expires, you will receive instant chat messages with increasing frequency to that effect.

Disk

The Disk frame shows the status of the currently used partition where the data directory is located on the hard disk of the physical machine.

The status shows total, used, and free disk space, and also the warning limit. If the free disk space reaches this limit, you will receive an Alerts to this effect. The warning will also be logged in the Journal Panel.

The warning limit is defined in the Preferences window.

Memory

The Memory frame shows an overview of the physical memory of the server both in numeric values and over time.

Health

The Health frame shows various Graphic Hub status parameters.

• Deadlocks: Shows the number of deadlocks in the system. Any deadlocks will necessitate the restarting of Graphic Hub.

• Active sessions: Shows the number of current sessions.

• File opens: Shows the total number of opened files.

• Files: Shows the total number of files stored in the system.

• Files in memory: Shows the number of currently open files. If it remains greater than 1 for an extended period of time, this may indicate locked files. In such cases, refer to the following procedures:

  • Restoring Corrupted Files

  • Graphic Hub Manager and Viz Artist Troubleshooting

• Open transactions: These are transactions that need to be deployed to the other server in the replication environment. If the number is too high, stop working until it is back to zero.

Cluster

If you are logged into both main and replication servers, you are presented with a Monitor Servers screen that reflects this.

• Title bar: Each server’s title bar shows its current status.

• Cluster: Shows if the cluster is connected and healthy.

• Open transactions: These are transactions that need to be deployed to the other server in the replication environment. If the number is too high, stop working until it is back to zero.

Activity

The Activity frame shows an overview of the server activity both in numeric values and over time.

• Calls: Shows the total number of calls made by any application to the Graphic Hub Server.

• Calls/sec: Shows the average number of calls per second.

• Peak: Shows the highest amount of calls during one second.

• Ø calls/sec: Shows the average number of calls during one second for the total run time of the server.

• Ø peak: Shows the highest amount of calls during one second for the total run time of the server.

Server details

This window shows information about the folders and files stored in the Graphic Hub and loaded into the memory.

To view server details

• In the Monitor servers window, click the Details button.

  

• From the Refresh Rate drop down box it is possible to set the interval of when the information should be updated.

• Selecting the Show Functions check box will show additional information used for debugging purposes.

  Note: Only users with administrator rights can access this window.

  
  The Total frame shows the following information:

• Projects: Shows the total number of projects in the Graphic Hub.

• Folders: Shows the total number of folders in the Graphic Hub.

• Files: Shows the total number of files in the Graphic Hub.

• Size: Shows the amount of storage space used by the data.

• Memory: The memory pane displays the currently open files, counted per type.

Warning and Error thresholds

Certain conditions that may cause problems or lead to errors, will be signaled by the Graphic Hub when certain thresholds are crossed. An orange or red signal in the Overview indicates an issue that should be investigated by the administrator as soon as possible. In addition, the Graphic Hub will provide a warning on shutdown, if one or more of the following conditions apply:

• Less than 1,600 MB hard disk space is available.

• More than 99 % physical memory is used.

• Less than 100 MB virtual memory is available.

  IMPORTANT! If less than 50 MB disk space is available, Graphic Hub does not allow any write operations, such as file create, truncate, or copy.

  In the Overview, Warning level issues are indicated by an orange parameter light, and suggests that a restart is recommended. Critical level issues are indicated by a red parameter light, and suggests that a restart is necessary. Check the log files for further details. The following table lists the most critical limits and warnings:

In addition to the situations described in the above table, the following conditions will produce a journal warning:

• 25 or more main/replication server switchbacks have occurred.

• 250,000 or more total open transactions have been processed.

• 7,500,000 or more critical calls have occurred (file created, truncated, written, replaced, copied, references changed).

• 9,000 or more total number of files (index information) in memory

• 48,000,000 or more total file opens.

• 2,000,000,000 or more total calls.

• Main, folder, keyword or file index data file size exceeds 1,536 MB.
  The following conditions will produce a journal critical error:

• 30 or more main/replication server switchbacks have occurred

• 500,000 or more total open transactions have been processed

• 8,000,000 or more critical calls occurred (file created, truncated, written, replaced, copied, references changed).

• 10,000 or more total number of file (index information) in memory.

Checksum information

View the checksum when you want to compare two or more Graphic Hub servers to see how identical they are. This is useful after having performed replication operations or when you have a real-time Deploy Agent. Empty servers will have a checksum of 00.

Use the Refresh button to update the checksum information for the servers currently logged on to. Checksum information includes:

• Total server checksum

• Folder structure (including file data)

• File data only

• File references only

• Pilot tables
  Empty servers will have a checksum of 00. When logged on to more than one server, right-clicking in the checksum information window will bring up the contextual menu, which gives access to:

• Open differences...: Opens the Server Diff window. From this window it is possible to detect differences between the servers (see Detect and solve server differences).

• Open differences and execute...: Opens the Server Diff window and executes the Diff all operation.

  Note: Execution time of Diff all varies depending on the database size and the amount of differences between the servers being compared.

• Open Pilot differences...: Opens the Pilot data differences window. See Resolve Pilot Data Differences Between Graphic Hubs. This option only appears when connected to a server that contains Pilot data.

• Properties: Opens the General server information window for the selected server.

To open the Chat panel

• Click View > Messages (Chat).

  Note: If receiving a message while the Chat panel is hidden, the panel will automatically open.

To send an instant message

1. Open the Chat panel.

2. Select the recipient from the left side of the panel.

3. Type a message text in the text box, and press <Enter>.
   The message will be sent to the selected Graphic Hub Manager and/or Viz Artist user(s).

   Tip: Messages sent to Global Message are delivered to everyone. Messages sent to a group are delivered to every group member currently logged in.

To view objects

• Click View > Object Types.

  

1. If logged in to more than one server, select which database to monitor from the Server list.

2. Each folder or file type is shown with its corresponding ID.
   Once an object is in the database, its type will be added to the object types list. The type will remain in the list even if all files of that type is deleted later on.
