Introduction in CubePL and Performance Analysis using Cube's Derived Metrics
|
Here is the table of currently supported calls in CubePL:
Operation | Explanation |
123.34 | a numerical constant |
"STRING" | a string constant |
-x | negative value of x |
() | grouping (priority) |
| | | absolute value |
+ - / * | arithmetical operations |
A^x | A in power of x |
> < >= <= != == | numerical comparison |
and or xor not | boolean operations |
eq | string comparison |
seq | case insensitive string comparison |
=~ /expression/ | matching of regular expression |
sin(x) cos(x) asin(x) acos(x) tan(x) cot(x) atan(x) acot(x) | trigonometrical functions |
ln(x) | natural logarithm of x |
exp(x) | natural exponent of x |
sqrt(x) | square root value of x |
random(x) | random number from 0 to x |
pos(x) | returns x, if x>, or 0 |
neg(x) | returns x, if x<0, or 0 |
sgn(x) | returns -1, if x<0, 0 if x is 0 and 1 is x>0 |
abs(x) | returns absolut value |
ceil(x) | returns smallest integer value, which is bigger than x |
floor(x) | returns biggest integer value, which is smaller than x |
min(x,y) | returns smaller value of x and y |
max(x,y) | returns bigger value of x and y |
uppercase(x) | returns uppercase version of x |
lowercase(x) | returns lowercase version of x |
env("x") | returns a value of the environment variable x |
local(var) | Declares (to compile time) a variable var as local. It cannot be redeclared later |
global(var) | Declares (to compile time) a variable var as global. It cannot be redeclared later |
${var} | 0th element of the variable with name var |
${var}[x] | x-th element of the variable with name var |
sizeof(var) | number of elements in the variable var |
defined(var) | returns true (1), if the variable var is defined, otherwise it returns false (0) |
metric::[uniq_name](i|e|*, i|e|*) | context sensetive value of metric uniq_name |
metric::context::[uniq_name](i|e|*, i|e|*) | context sensetive value of metric uniq_name |
metric::fixed::[uniq_name](i|e|*, i|e|*) | context independend value of metric uniq_name |
metric::call::[uniq_name](c_id, i|e|*, s_id, i|e|*) | value of metric uniq_name for the call path with id c_id and system resource with an id s_id |
cube::metric::set::[uniq_name]("X", "Y") | sets a property X of a metric uniq_name to value Y. Corrently supported are only "value" with value "VOID" or else |
cube::metric::get::[uniq_name]("X") | returns a property X of a metric uniq_name. Corrently supported are
