ConsoleManager allows you to control what gets sent to the console for both plugins and the server, allowing for easier spotting of important information. For example, the large amount of output that normally happens on startup, saying plugins are being loaded/enabled, world loading progress, and other information which isn't necessary, can all be turned off (at least the messages after this plugin is loaded).
Currently supports servers 1.7 - 1.9
Here is an example of a server startup when it has multiple plugins with ConsoleManager:

Configuration
# If enabled, the "Done" message when the server finishes
# loading will display despite other settings
keep-done-message: true
# Logging options for the base minecraft server
minecraft:
fatal: true
error: true
warn: true
info: false
trace: false
debug: false
# Logging options for the Bukkit/Spigot API
bukkit:
severe: true
warn: true
info: false
# General plugin options
plugins:
severe: true
warn: true
info: false
# Specific plugin options
# If you define a plugin here, it will override
# the plugins section above.
