Docker: Container Disk Throughput

Distribution: official part of Check_MK
License: GPL
Supported Agents: Linux

This check measures the throughput of block devices (disks) of docker containers. You can either have a single check for every single disk or a summary check (which is the default) summing up the throughput of all disks.

This check measures the memory usage of a docker container respecting either the memory limits of the docker node or the limit configured for the container.

Use the "Main memory usage (UNIX / Other Devices)" rule set to configure thresholds on the memory usage.


Either "SUMMARY" for a summarized check of all disks or the name of the disk device, e.g. "sda".


One service is created for each disk if the configuration is set to "single". If the configuration is set to "summary" one service is created for each host. If set to "legacy" then two services one for read and one for write is created (deprecated). The inventory is configured via diskstat_inventory_mode.
