.. _advanced/check-modulations: ================= Check modulations ================= How check modulations works ~~~~~~~~~~~~~~~~~~~~~~~~~~~ Depending on your configuration you may want to change the check_command during the night. For example, you want to send more packets for a ping during the night because there is less network activity so that you can get more accurate data. How to define a check_modulation ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ :: define checkmodulation{ checkmodulation_name ping_night check_command check_ping_night check_period night } define host{ check_command check_ping check_period 24x7 host_name localhost use generic-host checkmodulations ping_night } Here check_ping will be modulated into check_ping_night for the host localhost.
