sysstat Input Plugin

Collect sysstat metrics - requires the sysstat package installed.

This plugin collects system metrics with the sysstat collector utility sadc and parses the created binary data file with the sadf utility.

Configuration:

# Sysstat metrics collector
[[inputs.sysstat]]
  ## Path to the sadc command.
  #
  ## On Debian and Arch Linux the default path is /usr/lib/sa/sadc whereas
  ## on RHEL and CentOS the default path is /usr/lib64/sa/sadc
  sadc_path = "/usr/lib/sa/sadc" # required
  #
  #
  ## Path to the sadf command, if it is not in PATH
  # sadf_path = "/usr/bin/sadf"
  #
  #
  ## Activities is a list of activities, that are passed as argument to the
  ## sadc collector utility (e.g: DISK, SNMP etc...)
  ## The more activities that are added, the more data is collected.
  # activities = ["DISK"]
  #
  #
  ## Group metrics to measurements.
  ##
  ## If group is false each metric will be prefixed with a description
  ## and represents itself a measurement.
  ##
  ## If Group is true, corresponding metrics are grouped to a single measurement.
  # group = true
  #
  #
  ## Options for the sadf command. The values on the left represent the sadf options and
  ## the values on the right their description (wich are used for grouping and prefixing metrics).
  ##
  ## Run 'sar -h' or 'man sar' to find out the supported options for your sysstat version.
  [inputs.sysstat.options]
	-C = "cpu"
	-B = "paging"
	-b = "io"
	-d = "disk"             # requires DISK activity
	"-n ALL" = "network"
	"-P ALL" = "per_cpu"
	-q = "queue"
	-R = "mem"
	-r = "mem_util"
	-S = "swap_util"
	-u = "cpu_util"
	-v = "inode"
	-W = "swap"
	-w = "task"
  #	-H = "hugepages"        # only available for newer linux distributions
  #	"-I ALL" = "interrupts" # requires INT activity
  #
  #
  ## Device tags can be used to add additional tags for devices. For example the configuration below
  ## adds a tag vg with value rootvg for all metrics with sda devices.
  # [[inputs.sysstat.device_tags.sda]]
  #  vg = "rootvg"

Measurements & Fields:

If group=true

cpu
- pct_idle (float)
- pct_iowait (float)
- pct_nice (float)
- pct_steal (float)
- pct_system (float)
- pct_user (float)
disk
- avgqu-sz (float)
- avgrq-sz (float)
- await (float)
- pct_util (float)
- rd_sec_pers (float)
- svctm (float)
- tps (float)

And much more, depending on the options you configure.

If group=false

cpu_pct_idle
- value (float)
cpu_pct_iowait
- value (float)
cpu_pct_nice
- value (float)
cpu_pct_steal
- value (float)
cpu_pct_system
- value (float)
cpu_pct_user
- value (float)
disk_avgqu-sz
- value (float)
disk_avgrq-sz
- value (float)
disk_await
- value (float)
disk_pct_util
- value (float)
disk_rd_sec_per_s
- value (float)
disk_svctm
- value (float)
disk_tps
- value (float)

And much more, depending on the options you configure.

Example Output:

With the configuration below:

[[inputs.sysstat]]
  sadc_path = "/usr/lib/sa/sadc" # required
  activities = ["DISK", "SNMP", "INT"]
  group = true
  [inputs.sysstat.options]
	-C = "cpu"
	-B = "paging"
	-b = "io"
	-d = "disk"             # requires DISK activity
	-H = "hugepages"
	"-I ALL" = "interrupts" # requires INT activity
	"-n ALL" = "network"
	"-P ALL" = "per_cpu"
	-q = "queue"
	-R = "mem"
	"-r ALL" = "mem_util"
	-S = "swap_util"
	-u = "cpu_util"
	-v = "inode"
	-W = "swap"
	-w = "task"
  [[inputs.sysstat.device_tags.sda]]
    vg = "rootvg"

you get the following output:
