User’s Guide – version 1.6 NetWatch
19
If you are unhappy with the devices you have added, clicking on the ‘Reset Device
List’ button will clear the list. Once you have loaded your device(s) you may proceed
to step 2 by clicking the ‘Next’ button.
Step 2. Select Service Types
This step involves selecting the types of NetWatch service that you wish to use to
monitor the device(s). There are four individual service types:
Ping
A simple ping operation to test whether or not the device is responding. Response
time for the operation can also be recorded. An alert can be triggered when the ping
status changes or if response time exceeds a threshold.
TCP Port Test
Selected TCP ports are tested for status. For example, you may wish to monitor the
status of the SMTP port on your mail server. This test makes sure that connections
can be made to that port and records when it changes status. Configuration allows you
to set up multiple profiles for monitoring commonly used groups of ports. Alerts can
be triggered when ports change status, or if response time exceeds the configured
threshold.
SNMP Interface Test
Interfaces on the device are polled for status, utilisation and response time. Status
changes are recorded as well as, optionally, detailed utilisation statistics and SNMP
request response time, both of which can be graphed. Alerting occurs on status
change, response time and on utilisation levels. Note that an SNMP community string
is required.
SNMP Trap Reception
Generic SNMP Traps are received and recorded. Note that only traps and notifications
from devices configured with this service type will be recorded. An alert can be
triggered when a trap is received. At the current version, only the six generic traps are
received: Cold Start, Warm Start, Link Up, Link Down, Authentication Failure and
EGP Neighbour Loss.
