Situations that can trigger Notifications
IPCheck Server Monitor distinguishes between 3 status types
for a sensor:
· OK (Green)
means up and running
· WARNING
(Yellow) means one request has failed or the request time was above the warning
threshold
· DOWN (Red)
means at least 2 requests have failed or were above the timeout threshold
There are five situations that can trigger a
notification:
· On Error:
This notification is triggered if a server goes down and is not available
anymore (e.g. the sensor cannot connect to a service and runs into timeouts).
The associated color is red.
· On Warning:
Slow requests or user defined thresholds can trigger a warning notification. In
this case a sensor is shown in yellow color
· On OK: If a
sensor’s status changes from Error/DOWN or Warning to the UP status this
notification is triggered (e.g. to let you know that a server is UP again)
· On
Escalation: If a sensor has a DOWN state for a longer time you can trigger this
additional notification. Most users let IPCheck Server Monitor send out the
first ERROR notification to a smaller team and then – if the problem is not
solved e.g. in 5 minutes – a larger distribution list is notified using the
escalation notification.
· On Change:
Some sensors are able to monitor a service or file for changes in the content
(e.g. the HTTP Advanced sensor can discover changes in a webpage). If such a
change is discovered IPCheck will trigger a change notification
To avoid receiving too many notifications for only very
short failures or delays you can set so-called latencies. When latencies are set
(a value in seconds) a notification is only sent if the failure state takes
longer than the latency.
For example one configuration could look like this:
· Configure the
latency for DOWN to 60 seconds
· Configure the
latency for Escalations to 300 seconds
· Configure one
notification just to send emails and ICQ message
· Select this
notification for UP and DOWN
· Configure a
second notification to additionally send an SMS/pager notification
· Select this
notification for ESCALATION
Now if a sensor goes down you will be notified via email
and ICQ about 1 minute after a sensor goes down. If after 5 minutes the sensor
is still down you will additionally receive a SMS/Pager notification, e.g. in
case you are away from your email client
