# Chihaya recording rules
|
||||
#
|
||||
# Recording rules are queries that will be evaluated by prometheus periodically.
|
||||
# They can be used to rename, aggregate, transform or decorate any of the time series available.
|
||||
# After evaluation, their results are saved and they can be treated like any other time series.
|
||||
# The rules provided below are entirely optional, but proven to be very useful for monitoring instances of Chihaya.
|
||||
#
|
||||
# Set the global configuration fields scrape_interval and evaluation_interval to 5s for smooth evaluations.
|
||||
# All rules can (and should) be filtered or aggregated further.
|
||||
# They usually at least have the protocol, job, instance, and address_family fields.
|
||||
# Look at the chihaya:announce:rate1m rule for an example.
