NAME
pcp-slabinfo - Report statistics for kernel slab allocator
SYNOPSIS
pcp [ pcp options ] slabinfo [ -a archive ] [ -s samples ] [ -Z timezone ]
DESCRIPTION
The pcp-slabinfo command is used for viewing different stats related to slab. It helps users analyze useful information related to the slab allocator. The information includes the total number of objects that are currently active, allocated objects, pages per slab, etc. By default, pcp-slabinfo reports live data for the local host.
|
The statistics shown are as follows: |
OPTIONS
-a file , --archive = file
Fetch /proc/slabinfo for a specified archive file
-s count , --samples = count
Get the slabinfo statistics for specified number of samples count
-V , --version
Display version number and exit.
-z , --hostzone
Use the local timezone of the host that is the source of the performance metrics, as identified by either the -h or the -a options. The default is to use the timezone of the local host.
-Z timezone , --timezone = timezone
Use timezone for the date and time. Timezone is in the format of the environment variable TZ as described in environ (7).
-? , --help
Display usage message and exit.
NOTES
pcp-slabinfo collects information from /proc/slabinfo .
PCP ENVIRONMENT
Environment variables with the prefix PCP_ are used to parameterize the file and directory names used by PCP. On each installation, the file /etc/pcp.conf contains the local values for these variables. The $PCP_CONF variable may be used to specify an alternative configuration file, as described in pcp.conf (5).
For environment variables affecting PCP tools, see pmGetOptions (3).
