🦋 DESCRIPTION 🦋

So like, pcp-slabinfo is the girl you call when you wanna see all the different stats related to slab. She helps you analyze actually useful info about the slab allocator — no cap. That info 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, periodt.

The statistics shown are as follows:

• active_objs — The number of objects that are currently active (i.e., in use)
• num_objs — The total number of allocated objects (i.e. objects that are both in use and not in use).
• objsize — The size of objects in this slab, in bytes.
• objperslab — The number of objects stored in each slab.
• pagesperslab — The number of pages allocated for each slab
• active_slabs — The number of active slabs.
• num_slabs — The total number of slabs.

⭐ 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).
