Alerts allows you to create and modify alerts (i.e.,
notifications that are displayed by the application when a network
event meets the conditions specified in the alert). For example,
you can make NetResident notify you when a certain text is found in
an event.
Alerts
|
·
|
New –
creates a new alert. |
|
·
|
Modify –
modifies an existing alert. |
|
·
|
Delete – deletes an existing alert. |
Existing
alerts can be turned on and off using the checkbox next to the
alert name. When you create a new alert or modify an existing one,
the follow dialog is displayed:
Enter a
unique Name for the alert
and check the Enabled box
to make the alert active. The Filter frame allows you to select the
protocols that the alert applies to and to specify the text to
search for. For example, if you want to be alerted when the word
“specifications” is found in an FTP file transfer, check the
FTP box and enter
“specifications” in the text field. The text you search for should
consists of an unstructured natural language or “plain English”
query. In a natural language search request, words such as AND and
OR are disregarded. Use quotation marks to indicate a phrase, +
(plus) to indicate a word that must be present, and - (minus) to
indicate a word that must not be present. If you check the
Stemming box, your search
will include other grammatical forms of the words in your search
request. For example, with stemming enabled, a search for “apply”
would also find “applies.” This option has no effect for
non-English searches. If you check the Phonic box, your search will find words
that sound similar to the words in your request, like “Smith” and
“Smythe.” This option has no effect for non-English searches.
When the
text specified in the alert is found in an event, the corresponding
record is added to the log window (located below the alert list).
Additionally, the user can be notified by a number of configurable
Actions:
|
·
|
Beep – the computer beeps. |
|
·
|
Play
file – the specified WAV file is played back. |
|
·
|
Send
e-mail – sends an e-mail to the specified e-mail address.
You MUST configure NetResident to use your SMTP server prior to
sending e-mail. Use the E-mail
Setup button to enter your SMTP server settings. |
|
·
|
Show
message – displays the specified message as a system tray
notification balloon. |
|
·
|
Set a
priority – changes the event’s priority to the specified
value. |
|
·
|
Add a
comment – adds the specified comment to the event. |
|
·
|
Pronounce
message – makes Windows speak the specified text using the
text-to-speech engine. By default, Windows only comes with English
computer voices, so Windows may not be able to pronounce messages
correctly if the text is entered in a language other than
English. |
|
·
|
Write to
syslog – sends the message to the specified IP address using
the syslog protocol. |
|
·
|
Send SNMP
trap – sends the message to the specified IP address using
the SNMP protocol. The MIB file containing OID descriptions is
available upon request. |
|
·
|
Launch
application – launches the specified application (additional
command line parameters are supported). |
Multiple
actions can be configured for a single alert.
Note that
alerts are updated once a
minute, so once a matching event has occurred, it may take
up to a minute before the corresponding action(s) are performed.
Also, note that when you add a new alert, the entire database is
searched, so the alert may be triggered even if the related events
took place in the past.
