I can only find Linux instructions. I think I have the right package "CA Introscope 10.7.0.45 for Windows" however after installing a default installation I could not find any Precision API Monitoring files to be installed on my Windows APM Server and the online guide was only referring to a Linux install.
The CA Precision API Monitoring files are located in a separated install package.
The Online Guide (as of May 2018) for CA API Precision 3.3 was only referring to Linux based install.
The needed package is called:
CA PRECISION API MONITORING 3.3 GEN500000000001311.zip
And can downloaded from Support download site.
One can follow the CA Precision API Monitoring 3.2 install instructions for the APM Server side components for this integration.
