◆ ulonglong
◆ deinit_container_aware()
| void deinit_container_aware |
( |
| ) |
|
|
noexcept |
Release internal state and deinitialize container awareness.
◆ has_container_resource_limits()
| bool has_container_resource_limits |
( |
| ) |
|
Determines if container configurations has set resource limits.
- Returns
- true if container configuration resource limits
◆ init_container_aware() [1/2]
| bool init_container_aware |
( |
const bool |
is_container_aware | ) |
|
|
noexcept |
Determine if resource limits set by container must be respected and checks the correctness of the configurations.
Initializes internal state with input
- Parameters
-
| [in] | is_container_aware | true if container config must be respected |
- Returns
- true if container configurations are correct, false otherwise
◆ init_container_aware() [2/2]
| bool init_container_aware |
( |
const std::string & |
is_container_aware | ) |
|
|
noexcept |
Overloaded function for easy use.
- Parameters
-
| [in] | is_container_aware | string considered to be true if "ON", false otherwise |
- Returns
- true if container configurations are correct, false otherwise
◆ init_my_physical_memory() [1/2]
| bool init_my_physical_memory |
( |
const std::string & |
memory | ) |
|
Overloaded function for easy use.
- Parameters
-
| [in] | memory | string containing value of server_memory |
- Returns
- true on success, false if input memory value is invalid
◆ init_my_physical_memory() [2/2]
| bool init_my_physical_memory |
( |
ulonglong |
memory | ) |
|
Initialize the my_physical_memory function using server_memory option.
- Parameters
-
| [in] | memory | Value of the server_memory startup option |
- Note
- The input value of 0 indicates no limits, and underlying container/host configuration must be used
- Returns
- true on success, false if input memory value is invalid
◆ my_num_vcpus()
| uint32_t my_num_vcpus |
( |
| ) |
|
|
noexcept |
Determine the total number of logical CPUs available.
If process is running within a container, the number of logical CPUs is the maximum limit set for the container. If the process is not running in a container then it uses the appropriate system APIs to determine the number of logical CPUs.
If the API is unable to determine the number of logical CPUs, then it returns 0.
- Note
- : The container set limits are calculated from the CFS quota and period as quota/period and is round down. A limit of 0.5 will return the value 0 and is treated as though no limits are set.
- Returns
- number of logical CPUs or 0
◆ my_physical_memory()
| uint64_t my_physical_memory |
( |
| ) |
|
|
noexcept |
Determine the total physical memory available in bytes.
If process is running within a container, then memory available is the maximum limit set for the container. If the process is not running in a container then it uses the appropriate system APIs to determine the available memory.
If the API is unable to determine the available memory, then it returns 0.
- Returns
- physical memory in bytes or 0
