Variables and Thresholds Set as List:
-a, --variables=STRING[,STRING[,STRING...]]
#指定需要检测的项目，例如used_memory_human,connected_clients等，用单引号括起来，用分号隔开。
-w, --warn=STR[,STR[,STR[..]]]
> - warn
if
data is above this value (default
for
numeric values)
< - warn
if
data is below this value (must be followed by number)
= - warn
if
data is equal to this value (default
for
non-numeric values)
! - warn
if
data is not equal to this value
~ -
do
not check this data (must not be followed by number or

)
^ -
for
numeric values this disables check that warning < critical
Threshold values can also be specified as range
in
two forms:
num1:num2 - warn
if
data is outside range i.e.
if
data<num1 or data>num2
@num1:num2 - warn
if

通过nagiosql对check_redis命令定义，添加服务，注意定义check_redis命令时候命令类型为检测命令，不是各种命令
