Monitoring Resource Utilization With rcapstat
Use rcapstat to monitor the resource utilization of capped projects. To view an
example rcapstat report, see Producing Reports With rcapstat. You can set the sampling interval for the report and specify the
number of times that statistics are repeated. - interval
Specifies the sampling interval in seconds. The default interval is 5 seconds. - count
Specifies the number of times that the statistics are repeated. By default, rcapstat reports statistics until a termination signal is received or until the rcapd process exits.
The paging statistics in the first report issued by rcapstat show the activity
since the daemon was started. Subsequent reports reflect the activity since the last
report was issued. The following table defines the column headings in an rcapstat report. rcapstat Column
Headings |
Description |
|---|
id |
The project ID of the capped project. |
project |
The project name. |
nproc |
The number of processes
in the project. |
vm |
The total amount of virtual memory size used by processes
in the project, including all mapped files and devices, in kilobytes (K), megabytes
(M), or gigabytes (G). |
rss |
The estimated amount of the total resident set size (RSS)
of the processes in the project, in kilobytes (K), megabytes (M), or gigabytes
(G), not accounting for pages that are shared. |
cap |
The RSS cap defined for the
project. See Attribute to Limit Physical Memory Usage or the rcapd(1M) man page for information about how to
specify memory caps. |
at |
The total amount of memory that rcapd attempted to page out
since the last rcapstat sample. |
avgat |
The average amount of memory that rcapd attempted to
page out during each sample cycle that occurred since the last
rcapstat sample. The rate at which rcapd samples collection RSS can be set
with rcapadm. See rcapd Operation Intervals. |
pg |
The total amount of memory that rcapd successfully paged
out since the last rcapstat sample. |
avgpg |
An estimate of the average amount of
memory that rcapd successfully paged out during each sample cycle that occurred since
the last rcapstat sample. The rate at which rcapd samples process RSS sizes
can be set with rcapadm. See rcapd Operation Intervals. |
