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 has 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. | 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.
|
SNMP, SCI |
Last Connection Failure Details | If the test or collection fails, STA provides information on the cause of failure. | SNMP, SCI |
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.
