subset

parallel

scopable True
required False
provisioning False
default False
inheritance leaf > head
scope order specific > generic
candidates True | False
convert boolean

If set to true, actions are executed in parallel amongst the subset member resources.

pg_blkio_weight

scopable True
required False
provisioning False
default None
inheritance leaf
scope order specific > generic
depends create_pg in [True]
convert integer

Block IO relative weight. Value: between 10 and 1000. Kernel default: 1000.

pg_cpu_quota

scopable True
required False
provisioning False
default None
inheritance leaf
scope order specific > generic
depends create_pg in [True]

The percent ratio of one core to allocate to the process group if % is specified, else the absolute value to set in the process group parameter. For example, on Linux cgroups, -1 means unlimited, and a positive absolute value means the number of microseconds to allocate each period. 50%@all means 50% of all cores, and 50%@2 means 50% of two cores.

pg_cpu_shares

scopable True
required False
provisioning False
default None
inheritance leaf
scope order specific > generic
depends create_pg in [True]
convert integer

Kernel default value is used, which usually is 1024 shares. In a cpu-bound situation, ensure the service does not use more than its share of cpu ressource. The actual percentile depends on shares allowed to other services.

pg_cpus

scopable True
required False
provisioning False
default None
inheritance leaf
scope order specific > generic
depends create_pg in [True]

Allow service process to bind only the specified cpus. Cpus are specified as list or range : 0,1,2 or 0-2

pg_mem_limit

scopable True
required False
provisioning False
default None
inheritance leaf
scope order specific > generic
depends create_pg in [True]
convert size

Ensures the service does not use more than specified memory (in bytes). The Out-Of-Memory killer get triggered in case of tresspassing.

pg_mem_oom_control

scopable True
required False
provisioning False
default None
inheritance leaf
scope order specific > generic
depends create_pg in [True]
convert integer

A flag (0 or 1) that enables or disables the Out of Memory killer for a cgroup. If enabled (0), tasks that attempt to consume more memory than they are allowed are immediately killed by the OOM killer. The OOM killer is enabled by default in every cgroup using the memory subsystem; to disable it, write 1.

pg_mem_swappiness

scopable True
required False
provisioning False
default None
inheritance leaf
scope order specific > generic
depends create_pg in [True]
convert integer

Set a swappiness value for the process group.

pg_mems

scopable True
required False
provisioning False
default None
inheritance leaf
scope order specific > generic
depends create_pg in [True]

Allow service process to bind only the specified memory nodes. Memory nodes are specified as list or range : 0,1,2 or 0-2

pg_vmem_limit

scopable True
required False
provisioning False
default None
inheritance leaf
scope order specific > generic
depends create_pg in [True]
convert size

Ensures the service does not use more than specified memory+swap (in bytes). The Out-Of-Memory killer get triggered in case of tresspassing. The specified value must be greater than pg_mem_limit.
