Issue/Introduction

• The Article "How to use error handling in e2e_appmon scripts (example script)" contains all of the information you need to catch an error and send an alarm. Its attached to that Article and also attached to this Article as well for convenience.
• Please also make sure you have the "Dump screen on timeout" option enabled besides what you do in the script to dump any screens, e.g., the desktop so the state of the script run is captured when it fails.
• VNC/Team Viewer and LAN Manager are excellent for remote viewing purposes and a lot of issues can be identified when a script fails through the use of remote viewing. That said, when scripts fail due to unannounced web site or client app code changes script automation for error handling is highly recommended.

Environment

Component: E2E

Resolution

Examples:

Example 1:

You can apply code in your e2e script to generate an alarm, here's an example:

qostime = nimQoSGetTimer()
if qostime >= 8000 then
nimAlarm(3,"The value exceeds the threshold...","a_suppression_key","1.1.14")
else
nimAlarm(0,"The value is below the threshold...","a_suppression_key","1.1.14")
endif

Example 2:

Looking at the sample e2e scripts in e2e_scripting\Scripts directory has some script examples, e.g., example-correlation, and Nimbus functions including nimalarm(), nimalarmsimple() are defined in NimBUS-functions file in the same directory.

-- This example will show how to use triggers as part of a correlation rule

-- note that the trigger state may be retrieved by 2 methods.

-- An alarm will be fired if both triggers are active and a failed ping.


if trigger.state ("example.system") and state("example.network") then

if not action.ping("www.nimsoft.com") then

nimbus.alarm (2,"We have a situation here...")

end

end
