PROGRAM:
NAME
pmdazswap - zswap (compressed swap) PMDA
DESCRIPTION
pmdazswap is a Performance Metrics Domain Agent (PMDA) which exports metric values about
compressed swap operation, as tracked by the zswap Linux kernel module.
Zswap is a lightweight compressed cache for swap pages. It takes pages that are in the
process of being swapped out and attempts to compress them into a dynamically allocated
RAM-based memory pool. Zswap trades CPU cycles for potentially reduced swap I/O. This
tradeoff can also result in a performance improvement if reads from the compressed cache
are faster than reads from a swap device.
This PMDA exports metrics about pool size, number of pages stored, and various counters
for the reasons pages are rejected.
INSTALLATION
Install the zswap PMDA by using the Install script as root:
# cd $PCP_PMDAS_DIR/zswap
# ./Install
To uninstall, do the following as root:
# cd $PCP_PMDAS_DIR/zswap
# ./Remove
pmdazswap is launched by pmcd(1) and should never be executed directly. The Install and
Remove scripts notify pmcd(1) when the agent is installed or removed.
Use pmdazswap online using onworks.net services
