Hey Agus12,

an "External Monitor" based on external BASH-Scripts is most likely used for rather complex monitoring tasks and should not used for simple monitoring tasks. It would just add unnessecary complexity....

The curl commands your DEVs handed out are looking very simplistic and right now I dont see a good reason to put those CURL commands natively into an external monitoring script. A regular HTTP/HTTPS Monitor with tailordered SEND/RECEIVE strings should be able monitor the availability of your application.

Before helping you to create SEND/RECEIVE strings, you should clarify with your development why they included the -cookie directive and why they enabling the -G option (use GET instead of POST requests) if the -d option uses JSON formated params meant for POST payload. The combination of -G and JSON formated payload results in a slighly broken request URI:

 

[itacs@kw-f5-dev:Active:Standalone] config # curl -vvv --cookie session_cookie -G -d '{"request":"ping"}' http://10.0.17.23:81
*   Trying 10.0.17.23...
* Connected to 10.0.17.23 (10.0.17.23) port 81 (#0)
> GET /?{"request":"ping"} HTTP/1.1
> Host: 10.0.17.23:81
> User-Agent: curl/7.47.1
> Accept: */*
>

 

Cheers, Kai
