ZRAM

Plugin: proc.plugin Module: /sys/block/zram

Overview

Monitor zRAM device capacity, compression, memory use, and I/O activity on Linux systems. zRAM, or compressed RAM, uses a portion of system memory as a block device; data written to it is compressed and stored in memory.

The collector provides information about the operation and effectiveness of zRAM on your system.

This collector is supported on all platforms.

This collector supports collecting metrics from multiple instances of this integration, including remote instances.
