Comparison

• The result of the comparison operation is a filtered time series with the only matching data points

== # equal
!= # not-equal
> # greater-than
< # less-than
rate(node_network_receive_bytes_total[5m]) < 2300
rate(node_network_receive_bytes_total[5m]) < bool 2300 # returns 1 for true comparisons and 0 for false (instead of the actual value)


>= # greater-or-equal
<= # less-or-equal

Logical

# intersection
and

# union
metric1 or metric2 or metric3 # return all the time series with names metric1, metric2 and metric3

# complement
unless
