Process enactment technology provides native tools and add-ons for monitoring, such as APIs and monitoring consoles, which are usually highly entangled with the underlying process enactment logic and not customizable by process users. In such a case, all users access the same set of monitoring data and functions and process management resources may be allocated for monitoring concerns not of interest for users. In this context, we present a model and a tool for customized process monitoring infrastructures executing on top of existing process enactment technology. The model classifies the options about monitoring over which the preferences of process users may diverge. The tool implements the proposed model, generating customized process mo...
