ZFS Metrics via Telegraf
Ship your ZFS Metrics via Telegraf to your Logit.io Stack
Configure Telegraf to ship ZFS metrics to your Logit.io stacks via Logstash.
Follow this step by step guide to get 'logs' from your system to Logit.io:
Step 1 - Install Telegraf
This integration allows you to configure a Telegraf agent to send your metrics, in multiple formats, to Logit.io.
Telegraf is a flexible server agent equipped with plug-in support, useful for sending metrics and events from data sources like web servers, APIs, application logs, and cloud services.
To ship your metrics to Logit.io, we will integrate the relevant input and outputs.http plug-in into your Telegraf configuration file.
Choose the install for your operating system below to get started:
Windows
wget https://dl.influxdata.com/telegraf/releases/telegraf-1.19.2_windows_amd64.zip
Download and extract to: C:\Program Files\Logitio\telegraf\
Configuration file: C:\Program Files\Logitio\telegraf\
MacOS
brew install telegraf
Configuration file x86_64 Intel: /usr/local/etc/telegraf.conf
Configuration file ARM (Apple Silicon): /opt/homebrew/etc/telegraf.conf
Ubuntu/Debian
wget -q https://repos.influxdata.com/influxdata-archive_compat.key
echo '393e8779c89ac8d958f81f942f9ad7fb82a25e133faddaf92e15b16e6ac9ce4c influxdata-archive_compat.key' | sha256sum -c && cat influxdata-archive_compat.key | gpg --dearmor | sudo tee /etc/apt/trusted.gpg.d/influxdata-archive_compat.gpg > /dev/null
echo 'deb [signed-by=/etc/apt/trusted.gpg.d/influxdata-archive_compat.gpg] https://repos.influxdata.com/debian stable main' | sudo tee /etc/apt/sources.list.d/influxdata.list
sudo apt-get update
sudo apt-get install telegraf
Configuration file: /etc/telegraf/telegraf.conf
RedHat and CentOS
cat <<EOF | sudo tee /etc/yum.repos.d/influxdata.repo
[influxdata]
name = InfluxData Repository - Stable
baseurl = https://repos.influxdata.com/stable/\$basearch/main
enabled = 1
gpgcheck = 1
gpgkey = https://repos.influxdata.com/influxdata-archive_compat.key
EOF
sudo yum install telegraf
Configuration file: /etc/telegraf/telegraf.conf
SLES & openSUSE
zypper ar -f obs://devel:languages:go/ go
zypper in telegraf
Configuration file: /etc/telegraf/telegraf.conf
FreeBSD/PC-BSD
sudo pkg install telegraf
Configuration file: /etc/telegraf/telegraf.conf
Step 2 - Configure the Telegraf input plugin
The configuration file below is pre-configured to scrape the system metrics from your hosts, add the following code to the configuration file /etc/telegraf/telegraf.conf
from the previous step.
# Read metrics of ZFS from arcstats, zfetchstats, vdev_cache_stats, pools and datasets
# This plugin ONLY supports Linux & FreeBSD
[[inputs.zfs]]
## ZFS kstat path. Ignored on FreeBSD
## If not specified, then default is:
# kstatPath = "/proc/spl/kstat/zfs"
## By default, telegraf gather all zfs stats
## Override the stats list using the kstatMetrics array:
## For FreeBSD, the default is:
# kstatMetrics = ["arcstats", "zfetchstats", "vdev_cache_stats"]
## For Linux, the default is:
# kstatMetrics = ["abdstats", "arcstats", "dnodestats", "dbufcachestats",
# "dmu_tx", "fm", "vdev_mirror_stats", "zfetchstats", "zil"]
## By default, don't gather zpool stats
# poolMetrics = false
## By default, don't gather dataset stats
# datasetMetrics = false
Step 3 - Configure the output plugin
Once you have generated the configuration file, you need to set up the output plug-in to allow Telegraf to transmit your data to Logit.io in Prometheus format. This can be accomplished by incorporating the following code into your configuration file:
[[outputs.http]]
url = "https://<your-metrics-username>:<your-metrics-password>@<your-metrics-stack-id>-vm.logit.io:0/api/v1/write"
data_format = "prometheusremotewrite"
[outputs.http.headers]
Content-Type = "application/x-protobuf"
Content-Encoding = "snappy"
Step 4 - Start Telegraf
Windows
telegraf.exe --service start
MacOS
telegraf --config telegraf.conf
Linux
sudo service telegraf start
for systemd installations
systemctl start telegraf
Step 5 - View your metrics
Data should now have been sent to your Stack.
If you don't see metrics take a look at How to diagnose no data in Stack below for how to diagnose common issues.

Step 7 - Telegraf ZFS Overview
In order to effectively monitor and analyze ZFS metrics across a distributed environment, it's essential to employ a comprehensive and efficient metrics management solution. Telegraf, an open-source server agent for collecting and sending telemetry data, fits this requirement perfectly, able to gather ZFS metrics from a variety of sources including operational ZFS instances, databases, and other associated applications.
Telegraf's extensive selection of input plugins enables users to collect metrics from diverse sources such as CPU usage, memory utilization, disk I/O, and more, all of which can be vital for understanding ZFS performance. To store and scrutinize these collected metrics, organizations can utilize Prometheus, an open-source monitoring and alerting tool known for its flexible querying language and powerful data visualization capabilities.
To convey ZFS metrics from Telegraf to Prometheus, organizations must configure Telegraf to output metrics in Prometheus format, then establish Prometheus to scrape these metrics from the Telegraf server. This procedure includes setting up Telegraf to gather ZFS metrics, outputting them in Prometheus format, configuring Prometheus to fetch these metrics from the Telegraf server, and subsequently interpreting the data through Prometheus's robust querying and visualization tools.
Upon successful integration of the metrics into Prometheus, further analysis and visualization can be carried out using Grafana. Grafana, an open-source software recognized for its monitoring and observability capabilities, is fully compatible with Prometheus. It empowers users to design dynamic, interactive dashboards for a deeper exploration of metrics data, delivering a comprehensive understanding of performance trends and potential bottlenecks in the ZFS system.
