The Linux Metrics integration allows you to monitor Linux servers.

Use the Linux Metrics integration to collect low-level metrics. Then visualize that data in Kibana, create alerts to notify you if something goes wrong, and reference data when troubleshooting an issue.

For example, you could install the Linux Metrics integration to send metrics to Elastic. Then, you could view real-time changes to service status in Kibana's [Metrics Linux] Host Services Overview dashboard.

Data streams

The Linux Metrics integration collects one type of data: metrics.

Metrics give you insight into the state of the machine. Metric data streams collected by the Linux Metrics integration include performance counter values, memory usage, entropy availability, and more. See more details in the Metrics reference.

Requirements

You need Elasticsearch for storing and searching your data and Kibana for visualizing and managing it. You can use our hosted Elasticsearch Service on Elastic Cloud, which is recommended, or self-manage the Elastic Stack on your own hardware.

Certain data streams may access /proc to gather process information, and the resulting ptrace_may_access() call by the kernel to check for permissions can be blocked by AppArmor and other LSM software, even though the System module doesn't use ptrace directly.

Setup

For step-by-step instructions on how to set up an integration, see the Getting started guide.

Note: Because the Linux Metrics integration always applies to the local server, the hosts config option is not needed.

Note: When running inside a container the proc filesystem directory of the host should be set using system.hostfs setting to /hostfs.

Metrics reference

Conntrack

The conntrack module reports on performance counters for the Linux connection tracking component of netfilter. Conntrack uses a hash table to track the state of network connections.

Iostat

The iostat module reports per-disk IO statistics that emulate iostat -x on Linux.

KSM

The KSM module reports data from Kernel Samepage Merging. To take advantage of KSM, applications must use the madvise system call to mark memory regions for merging. KSM is not enabled on all distros, and KSM status is set with the CONFIG_KSM kernel flag.

Memory

The memory data stream extends system/memory and adds Linux-specific memory metrics, including Huge Pages and overall paging statistics.

Pageinfo

The pageinfo data stream reports on paging statistics as found in /proc/pagetypeinfo.

Reported metrics are broken down by page type: DMA, DMA32, Normal, and Highmem. These types are further broken down by order, which represents zones of 2^ORDER*PAGE_SIZE. These metrics are divided into two reporting types:

• buddyinfo is summarized by page type (as in /proc/buddyinfo)
• nodes reports information broken down by memory migration type

This information can be used to determine memory fragmentation. The kernel buddy algorithm will always search for the smallest page order to allocate, and if none is available, a larger page order will be split into two "buddies." When memory is freed, the kernel will attempt to merge the "buddies." If the only available pages are at lower orders, this indicates fragmentation, as buddy pages cannot be merged.

Entropy

This is the entropy data stream of the module system. It collects the amount of available entropy in bits. On kernel versions greater than 2.6, entropy will be out of a total pool size of 4096.

Socket

Note: This data stream requires kernel 2.6.14 or newer.

The Linux socket data stream reports an event for each new TCP socket that it sees. It does this by polling the kernel periodically to get a dump of all sockets. You set the polling interval by configuring the period option. Specifying a short polling interval with this data stream is important to avoid missing short-lived connections.
