Log Viewing Attributes
Trigger on
Select the method of triggering a notification:
Byte Count:
A specific number of bytes of data. This is the default.
Text String Recognition:
A specific pattern of characters, which you can
define by a regular expression.
Note:
Text string recognition may negatively impact the SLC unit’s performance,
particularly when regular expressions are used.
Byte Threshold
The number of bytes of data the port receives before the SLC console manager
captures log data and sends a notification 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 device receives a small number of
bytes, it perceives that your device needs some attention. The SLC unit notifies
your technician when that point has been passed, and the notification includes
the logged data.
For example, a threshold preset at 30 characters means that as soon as the SLC
console manager receives 30 bytes of data, it captures log data and sends an
email regarding this port.
Text String
The specific pattern of characters the SLC unit must recognize before sending a
notification to the technician about this port. The maximum is 100 characters. You
may use a regular expression to define the pattern. For example, the regular
expression “abc[def]g” recognizes the strings abcdg, abceg, abcfg.
The SLC console manager supports GNU regular expressions; for more
information, see:

Email Delay
A time limit of how long (in seconds), after the SLC unit detects the trigger, that
the device port captures data before closing the log file (with a fixed internal buffer
maximum capacity of 1500 bytes) and sending a notification. The default is
60
seconds.
Restart Delay
The number of seconds for the period after the notification has been sent during
which the device port ignores additional characters received. The data is simply
ignored and does not trigger additional alarms until this time elapses. The default
is
60
seconds.
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 up to 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 replaced
with the device port number automatically.
Displays
Select to view either the beginning (head) or end (tail) of the log.
Number of Lines
Number of lines from the head or tail of the log to display.
