ZPOOL_INFLUXDB(8) FreeBSD System Manager's Manual ZPOOL_INFLUXDB(8)
NAME
zpool_influxdb - collect ZFS pool statistics in InfluxDB line protocol
format
SYNOPSIS
zpool_influxdb [-e|--execd] [-n|--no-histogram]
[-s|--sum-histogram-buckets]
[-t|--tags key=value[,key=value]<?>] [pool]
DESCRIPTION
zpool_influxdb produces InfluxDB-line-protocol-compatible metrics from
zpools. Like the zpool command, zpool_influxdb reads the current pool
status and statistics. Unlike the zpool command which is intended for
humans, zpool_influxdb formats the output in the InfluxDB line protocol.
The expected use is as a plugin to a metrics collector or aggregator,
such as Telegraf.
By default, zpool_influxdb prints pool metrics and status in the InfluxDB
line protocol format. All pools are printed, similar to the zpool status
command. Providing a pool name restricts the output to the named pool.
OPTIONS
-e, --execd Run in daemon mode compatible with Telegraf's execd plugin.
In this mode, the pools are sampled every time a newline
appears on the standard input.
-n, --no-histogram
Do not print latency and I/O size histograms. This can
reduce the total amount of data, but one should consider the
value brought by the insights that latency and I/O size
distributions provide. The resulting values are suitable
for graphing with Grafana's heatmap plugin.
-s, --sum-histogram-buckets
Accumulates bucket values. By default, the values are not
accumulated and the raw data appears as shown by zpool
iostat. This works well for Grafana's heatmap plugin.
Summing the buckets produces output similar to Prometheus
histograms.
-t, --tags key=value[,key=value]<?>
Adds specified tags to the tag set. No sanity checking is
performed. See the InfluxDB Line Protocol format
documentation for details on escaping special characters
used in tags.
-h, --help Print a usage summary.
