|
.
|
|
.Sh DESCRIPTION
|
|
.Nm
|
|
produces InfluxDB-line-protocol-compatible metrics from zpools.
|
|
Like the
|
|
.Nm zpool
|
|
command,
|
|
.Nm
|
|
reads the current pool status and statistics.
|
|
Unlike the
|
|
.Nm zpool
|
|
command which is intended for humans,
|
|
.Nm
|
|
formats the output in the InfluxDB line protocol.
|
|
The expected use is as a plugin to a
|
|
metrics collector or aggregator, such as Telegraf.
|
|
.Pp
|
|
By default,
|
|
.Nm
|
|
prints pool metrics and status in the InfluxDB line protocol format.
|
|
All pools are printed, similar to the
|
|
.Nm zpool Cm status
|
|
command.
|
|
Providing a pool name restricts the output to the named pool.
|
|
.
|
|
.Sh OPTIONS
|
|
.Bl -tag -width "-e, --execd"
|
|
.It Fl e , -execd
|
|
Run in daemon mode compatible with Telegraf's
|
|
.Nm execd
|
|
plugin.
|
|
In this mode, the pools are sampled every time a
|
|
newline appears on the standard input.
|
|
.It Fl 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.
|
|
.It Fl s , -sum-histogram-buckets
|
|
Accumulates bucket values.
|
|
By default, the values are not accumulated and the raw data appears as shown by
|
|
.Nm zpool Cm iostat .
|
|
This works well for Grafana's heatmap plugin.
|
|
Summing the buckets produces output similar to Prometheus histograms.
|
|
.It Fl t , Fl -tags Ar key Ns = Ns Ar value Ns Oo , Ns Ar key Ns = Ns Ar value Oc Ns …
|
|
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.
|
|
.It Fl h , -help
|
|
Print a usage summary.
