v4.0.0-rc.2

Added

• Multi query endpoint. You no longer need to run a single instance per NetScaler you want to monitor. The exporter now supports Prometheus targets so only one instance is required.
• Up gauge. This will be either 1 or 0 depending on whether the NetScaler responds or not.

Changed

• Refactored exporter code into separate package for maintainability reasons.

Removed

• Option to specify a NetScaler to scrape from the command line. Using Prometheus scrape targets is now the only way.
