This collector is supported on all platforms. This collector supports collecting metrics from multiple instances of this integration, including remote instances. This integration doesn't support auto-detection. The default configuration for this integration does not impose any limits on data collection. The default configuration for this integration is not expected to impose a significant performance impact on the system. Metrics grouped by scope. The scope defines the instance that the metric belongs to. An instance is uniquely identified by a set of labels. Labels: | Label | Description | |:--|:-| | container_name | The container name or group path if name resolution fails. | | image | Docker/Podman container image name. | Metrics: | Metric | Dimensions | Unit | |:|:-|:-| | cgroup.cpu_limit | used | percentage | | cgroup.cpu | user, system | percentage | | cgroup.cpupercore | a dimension per core | percentage | | cgroup.throttled | throttled | percentage | | cgroup.throttled_duration | duration | ms | | cgroup.cpu_shares | shares | shares | | cgroup.mem | cache, rss, swap, rsshuge, mappedfile | MiB | | cgroup.writeback | dirty, writeback | MiB | | cgroup.mem_activity | in, out | MiB/s | | cgroup.pgfaults | pgfault, swap | MiB/s | | cgroup.mem_usage | ram, swap | MiB | | cgroup.memusagelimit | available, used | MiB | | cgroup.mem_utilization | utilization | percentage | | cgroup.mem_failcnt | failures | count | | cgroup.io | read, write | KiB/s | | cgroup.serviced_ops | read, write | operations/s | | cgroup.throttle_io | read, write | KiB/s | | cgroup.throttleservicedops | read, write | operations/s | | cgroup.queued_ops | read, write | operations | | cgroup.merged_ops | read, write | operations/s | | cgroup.cpusomepressure | some10, some60, some300 | percentage | | cgroup.cpusomepressurestalltime | time | ms | |
