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’s performance, particularly when regular expressions
are used.
Byte Threshold
The number of bytes of data the port receives before the
SLC 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 receives a small number of bytes, it perceives that
your device needs some attention. The SLC 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 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), after the SLC 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.
Text String
The specific pattern of characters the SLC 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 supports GNU regular expressions; for more

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.
