External Check
The External Check monitor captures asynchronous events. Uptime Infrastructure Monitor does not actively monitor these events by polling or initiating service checks; instead, External Check monitors rely on an external event to generate the information that the monitors capture. External Check monitors enable you to determine when to collect service data for the event that you specify.
After you define an External Check monitor, it has a status of UNKNOWN until the it is updated with a URI similar to the following template:
| Code Block |
|---|
http://$UPTIME_HOST:9996/command?command=externalcheck&name=$ELEMENT$MONITOR_NAME&status=$STATUS&message=$MESSAGE&hostname=$MONITOR$ELEMENT_NAME |
$UPTIME_HOST: the hostname of the Uptime Infrastructure Monitor Monitoring Station
$ELEMENT_NAME: the hostname (not display name) of the system the External Check is assigned to
$STATUS: an integer indicating the status of the monitor: 0 = OK, 1 = WARN, 2 = CRIT
$MESSAGE: the message explaining the status
$MONITOR_NAME: the name of the External Check monitor
A sample script, extevent.pl, is included with Uptime Infrastructure Monitor in the /scripts subdirectory, and serves as an example of how to automate the receiving of asynchronous events, and update the External Check monitor accordingly. When the script is called with the appropriate arguments, it connects to Uptime Infrastructure Monitor command port (9996), and updates the status, triggering the appropriate Alert Profiles and Action Profiles.
