When a service outage occurs, Uptime Infrastructure Monitor can generate an alert in a number of ways including sending an email, opening a Windows pop-up or initiating a pager message. You can also define your own Script Alert that will be executed on the monitoring station when an outage occurs. You can use the Script Alert option to create custom alerting methods that fit your exact needs. Some examples of custom alerting implementations include:

How custom alert scripts work

Please review the online documentation available here - Alerts and Actions

Custom alert scripts are defined with the Script Alert option on the Alert Profile page. The script is a path to a script or executable on the monitoring station system that Uptime Infrastructure Monitor will run when a service outage occurs. You control the actions that the script or executable takes, which provides full control over how Uptime Infrastructure Monitor sends out alert notifications during a service outage.

For Windows alert scripts, the path used must use UNIX-style / instead of \ and must be quoted if your path contains spaces. For example:
"C:/Program Files/uptime software/uptime/scripts/my_custom_alerter.bat"

When Uptime Infrastructure Monitor runs the script or executable, it passes on information about the specific service outage that triggered the alert. This information is passed using the system environment variables that are local to each execution of the recovery script. The script or executable is run once for each Uptime Infrastructure Monitor user that will be notified using this alert.

The environment variables passed to the alert script and their meanings are included below but for the latest documentation please refer to Alert Profile and Action Profile Variables:

Environment Variable Examples

How the script or executable uses environment variables will vary depending on the language you have used to write your script or executable. The following examples illustrate how environment variables are accessed in several common languages:

LanguageCommon methods of accessing environment variables.

Use of the ENV array to access environment variables with Perl. For example:

my $user_email = $ENV{UPTIME_EMAIL};
my $user_mobile = $ENV{UPTIME_MOBILE};

PHPWhen run from the command line, use the getenv() function to access environment variables within PHP. For example:

$user_email = getenv('UPTIME_EMAIL');
$user_mobile = getenv('UPTIME_MOBILE');

Bash and KshBash and Ksh enable you to access local environment variables just like any other local variable. For example:


Batch FileAdd the % symbol around the names of environment variables in Windows batch files. For example:


VB ScriptUse the the oShell.Environment lookup function to access environment variables with VB Script. For example:

Dim email, mobile
Dim WshShell, objEnv

Set WshShell = CreateObject("WScript.Shell")

Set objEnv = WshShell.Environment("Process")

email = objEnv("UPTIME_EMAIL")
mobile = objEnv("UPTIME_MOBILE")
