getCpuAcctControlGroup
The control group for thecpuacct
subsystem.- Returns:
- the control group
-
getCpuAcctUsageNanos
public long getCpuAcctUsageNanos()The total CPU time consumed by all tasks in thecpuacct
control group fromcpuAcctControlGroup
.- Returns:
- the total CPU time in nanoseconds
-
getCpuControlGroup
The control group for thecpu
subsystem.- Returns:
- the control group
-
getCpuCfsPeriodMicros
public long getCpuCfsPeriodMicros()The period of time for how frequently the control group fromcpuControlGroup
has its access to CPU resources reallocated.- Returns:
- the period of time in microseconds
-
getCpuCfsQuotaMicros
public long getCpuCfsQuotaMicros()The total amount of time for which all tasks in the control group fromcpuControlGroup
can run in one period as represented bycpuCfsPeriodMicros
.- Returns:
- the total amount of time in microseconds
-
getCpuStat
The CPU time statistics. SeeOsStats.Cgroup.CpuStat
.- Returns:
- the CPU time statistics.
-
getMemoryControlGroup
The control group for thememory
subsystem.- Returns:
- the control group
-
getMemoryLimitInBytes
The maximum amount of user memory (including file cache). This is stored as aString
because the value can be too big to fit in along
. (The alternative would have beenBigInteger
but then it would not be possible to index the OS stats document into Elasticsearch without losing information, asBigInteger
is not a supported Elasticsearch type.)- Returns:
- the maximum amount of user memory (including file cache).
-
getMemoryUsageInBytes
The total current memory usage by processes in the cgroup (in bytes). This is stored as aString
for consistency withmemoryLimitInBytes
.- Returns:
- the total current memory usage by processes in the cgroup (in bytes).
-
