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.
