How it works

The plugin gathers global statistics using the performance counter client. No configuration is needed. It captures traffic rates, latencies and response codes of requests sent to the web server by parsing the IIS access log file. See next step for more information.

The minimal supported version of IIS is 7.0.


The plugin needs to be installed together with a CoScale agent, instructions on how to install the CoScale agent can be found here. If you want to monitor IIS inside Docker containers using CoScale, check out the instructions here.
