About the Monitored Libraries Table

The Monitored Libraries table shows the current status of all libraries monitored by STA.

To access the table, expand Setup & Administration and then select Library Connections. The table includes the following fields which are updated after a data collection or connection test.

Table Field	Description	Applies to:
Library Name	Name used to identify the library within STA.	SNMP, SCI
Library Complex	The identifier for the library complex. If this field is blank, it will be supplied after you perform a manual data collection.	SNMP, SCI
Library IP Address	The IP address of the monitored library.	SNMP, SCI
STA IP Address	IP address of the STA server.	SNMP, SCI
Library Engine ID	The unique SNMP engine ID for the library (see About the Library Engine ID).	SNMP only
Connection Type	Either SNMP or Library API (which is also known as SCI).	SNMP, SCI
Library API User ID	ID of the SL4000 user account to be used for SCI communication.	SCI only
Library API HTTP port	Port used for SCI HTTP communication. The default is 7102. Disabled by default.	SCI only
Library API HTTPS port	Port used for SCI HTTPS communication. The default is 7103.	SCI only
Recent Communication Status	Indicates the latest status of information from the library over the outbound SCI channel or SNMP trap channel. This may intermittently indicate `MISSED HEARTBEAT`. This is normal.	SNMP, SCI
Library Time Zone	The time zone of the library.	SNMP, SCI
Last Successful Connection	Date and time when the test or data collection was completed, if successful.	SNMP, SCI
Last Connection Attempt	Date and time when the connection test or data collection was initiated.	SNMP, SCI
Last Connection Status	Results of the test or data collection. ACCEPTED – The request is queued and data collection is preparing to start. IN PROGRESS – A data collection is underway. SUCCESS – The connection test or data collection completed successfully. FAILED – The connection test or data collection failed. Possible reasons are listed in the Last Connection Failure Detail field. REJECTED – The data collection request was rejected, possibly because the library is busy or unavailable. DUPLICATE – The data collection request was rejected because another one is already is progress.	SNMP, SCI
Last Connection Failure Details	If the test or collection fails, STA provides information on the cause of failure.	SNMP, SCI

For information about adding or editing monitored libraries:

For SNMP-connected libraries (SL150, SL500, SL3000, SL8500), see Configure the SNMP Connection to a Library.
For SCI-connected libraries (SL4000), see Add the SL4000 as a Monitored Library.

About the Library Engine ID

Every SNMP v3 agent has a globally unique hexadecimal engine ID to identify the device. The Library Engine ID is a field updated and displayed in the Monitored Libraries table.

When you configure a new SNMP connection on STA, leave the library engine ID blank. Then when you test the SNMP connection to the library, STA automatically retrieves the library engine ID and displays it in the Monitored Libraries table.

The Library Engine ID field may be blank if:

This is a new library connection, and you have not yet tested the connection.
You have modified an existing library connection. In this case, STA automatically clears the Library Engine ID field to indicate that the connection has been dropped and you must perform a new connection test.
The connection with the library has been dropped for any reason.

When to manually clear the Library Engine ID field:

Never modify the library engine ID value. However, you should manually clear the value at the following times.

If a connection test fails—in particular, if the error message indicates a failed trap channel test—you should clear the library engine ID before retesting the connection.
After a library firmware upgrade, you should clear the engine ID and perform a connection test.
