MVPHi Samyool,
you can't read locally stored file streams using iRules. The required TCL commands to open and read such are disabled by the developers.
The only chance I see for you, is to open a [SIDEBAND] connection to the REST-API, execute a tail /var/log/ltm command via the /mgmt/tm/util/bash endpoint, parse the REST response and finally display the output on your debugging page.
API Request:
POST /mgmt/tm/util/bash HTTP/1.1
Host: yourbox.domain.de
Content-Type: application/json
Authorization: Basic YourBase64Creds
content-length: 56
Connection: close
{"command":"run","utilCmdArgs":"-c 'tail -n 50 /var/log/ltm'"}
Note: Let me know if you need further assitence to implement such a [SIDEBAND] connection to query REST within iRules.
Cheers, Kai
