Use the Device Ports – Logging page to set logging parameters on individual ports.
To set logging parameters:
Complete or view the following sections:
Local Logging |
If you enable local logging, each device port stores 256 KB (approximately 400 screens) of I/O data in a true FIFO buffer Disabled is the default. |
Email Logging |
Select to enable email logging. Email logging sends an email message to pre-defined email addresses when alert criteria have been met. Data received on the SLC trigger the alert. The default is disabled. |
Byte Threshold |
The number of bytes of data the port will receive before the SLC will capture log data and send an email regarding this port. The default is 100 bytes. In most cases, the console port of your device does not send any data unless there is an alarm condition. After the SLC receives a small number of bytes, it perceives that your device needs some attention. The SLC contacts your technician by email when that point has been passed, and the email includes the logged data. A threshold preset at 30 characters means that as soon as the SLC receives 30 bytes of data, it captures log data and sends an email regarding this port. |
Email Delay |
A time limit of how long, in seconds, the device port will capture data before closing the log file (with a fixed internal buffer maximum capacity of 1500 bytes) and sending it as an email message. The SLC sends the data as the body text in the email message to your predefined recipients. The default is 60 seconds. |
Restart Delay |
The number of seconds for the period of time, after the email message has been sent, during which the device port will ignore additional characters received. The data will simply be ignored and not trigger additional alarms until this time elapses. The default is 60 seconds. Note: The email buffer does not collect any additional characters in its buffer during this ignore time. However, if syslog is also active, the logger still buffers any data to syslog. |
Email to |
The complete email address of the message recipient(s) for each device port(s). Each device port has its own recipient list. To enter more than one email address, separate the addresses with a single space. You can enter a total of 128 characters. |
Email Subject |
A subject text appropriate for your site. May have up to 128 characters. The email subject line is pre-defined for each port with its port number. You can use the email subject to inform the desired recipients of the problem on a certain server or location (e.g., server location or other classification of your equipment). This is helpful if the email message goes to the system administrator’s or service technician's mobile or wireless device (e.g., text messaging by means of email). Note: The character sequence %d anywhere in the email subject is automatically replaced with the device port number. |
NFS File Logging |
Select the checkbox to log all data that is sent to the device port to one or more files on an external NFS server. Disabled is the default. |
Directory to |
The path of the directory where the log files will be stored Note: This directory must be a directory exported from an NFS server that is mounted on the SLC. Specify the local directory path for the NFS mount. See NFS and SMB/CIFS . |
Max number of files |
The maximum number of files that will be created to contain log data to the port. These files keep a history of the data received from the port. Once this limit is exceeded, the oldest file is overwritten. The default is 10. |
Max size of files |
The maximum allowable file size in bytes. The default is 2048 bytes. Once the maximum size of a file is reached, the SLC begins generating a new file. |
PC Card Logging |
Select to enable PC Card logging. A PC Card Compact Flash must be loaded into one of the PC Card slots on the front of the SLC and properly mounted. Disabled by default. |
Log to |
If port logging is to a PC Card, select the slot (Upper or Lower) in which the PC Card has been inserted. Upper is the default. |
Max Number of files |
The maximum number of files to create to contain log data to the port. These files keep a history of the data received from the port. Once this limit is exceeded, the oldest file is overwritten. The default is 10. |
Max Size of files |
The maximum allowable file size in bytes. The default is 2048 bytes. Once the maximum size of a file is reached, the SLC begins generating a new file. The default is 2048 bytes. |
Syslog Logging |
Select to enable system logging. Note: The logging level for the device ports log must be set to Info to view Syslog entries for Device Port logging. |
Note: To apply the settings to additional device ports, in the Apply settings to Device Ports field, enter the additional ports, (e.g., 1-3, 5,6)
To save, click Apply.
