Telegraf for Eyer Observability

Eyer Observability Basics

Eyer Observability uses Telegraf to watch how systems work. It gathers, processes, and looks at data to understand system performance. Telegraf's plugins help collect data from many places and send it to different storage systems for analysis.

Input Plugin Setup

To set up input plugins for Eyer Observability:

Pick what you want to measure
Choose the right plugins from Telegraf's list
Set up the plugins in your telegraf.conf file

Here's an example to watch system data:

[[inputs.cpu]]
  percpu = true
  totalcpu = true
  collect_cpu_time = false
  report_active = false

[[inputs.disk]]
  ignore_fs = ["tmpfs", "devtmpfs", "devfs", "iso9660", "overlay", "aufs", "squashfs"]

Output Plugin Setup

Set up output plugins to send data where you want:

Pick the right output plugin (like InfluxDB or Graphite)
Add the plugin setup to your telegraf.conf file
Add connection details and any needed passwords

Example setup for InfluxDB output:

[[outputs.influxdb]]
  urls = ["http://localhost:8086"]
  database = "telegraf"
  username = "telegraf"
  password = "metricspassword"

Adjusting Data Collection Times

Change how often Telegraf collects data:

Setting	What it does	Example
interval	How often data is collected	"10s"
flush_interval	How often data is sent out	"10s"
precision	How exact the time stamp is	"s"

Change these settings in your telegraf.conf file:

[agent]
  interval = "10s"
  flush_interval = "10s"
  precision = "s"

Advanced Monitoring Methods

Using Aggregator and Processor Plugins

Telegraf's plugins help with better monitoring:

Processor plugins: Change data before sending it out
Aggregator plugins: Make summary data from collected info

Here's what these plugins can do:

Plugin Type	What it Does	Examples
Processor	Cleans up data	Removes private info, changes data format
Aggregator	Makes summary data	Calculates averages, finds highest and lowest values

Creating Custom Metrics

You can make your own metrics with Telegraf:

Grok Processor: Reads log files and makes metrics
Exec Input Plugin: Runs commands and uses the results

AIOps in Monitoring

What is AIOps?

AIOps means using AI and machine learning to help with IT operations. It makes managing and watching IT systems better by:

Looking at lots of data from different places
Finding and fixing problems before they get big
Doing some tasks automatically
Showing all IT stuff in one place

This helps with complex IT setups that use different cloud systems, containers, and small, separate services.

Adding Machine Learning

Machine learning is a big part of AIOps. It helps IT teams:

Look at more data than people can
Find out why problems happen
Suggest how to fix issues
Sometimes fix problems on its own

Here's what machine learning in AIOps can do:

What it does	How it helps
Spots weird things happening	Finds problems early
Guesses future issues	Solves problems before they start
Links related events	Fixes issues faster
Fixes common problems by itself	Less work for people

Predicting Issues with Data

AIOps is good at guessing when problems might happen before they cause trouble. It does this by:

Looking at old data to see patterns
Checking current data for odd things
Using smart tools to find out why things happen

This helps by:

Saving money on running things
Fixing problems faster
Making services more reliable
Making users happier

For example, AIOps can guess when these might happen:

Websites getting slow
Networks using too much data
Servers working too hard

Better Alert Management

Setting Smart Alert Levels

To set up good alert levels:

Use past data to set changing limits
Make different levels of alerts (like warning and emergency)
Think about how things change over time

Here's an example for CPU use alerts:

Alert Level	When to Alert	What Happens
Warning	>70% for 5 minutes	Tell the team
Critical	>85% for 2 minutes	Add more resources
Emergency	>95% for 1 minute	Call the on-call person

Connecting to Incident Tools

Linking your watching system to incident tools helps fix problems faster. It can:

Make tickets by itself
Send bigger problems to the right people
Keep track of all issues in one place

Good tools to use with Telegraf and InfluxDB are PagerDuty, OpsGenie, and ServiceNow. When you set these up:

Make sure they can talk back and forth
Match alert levels to how urgent the problem is
Set rules to send problems to the right teams

Reducing Duplicate Alerts

Too many alerts can be a problem. To fix this:

Group alerts: Put similar alerts together
Find related issues: Use AI to spot connected problems
Avoid flip-flop alerts: Don't keep alerting for unstable things

Wait before sending the same alert again:

Alert Type	Wait Time
Warning	15 minutes
Critical	5 minutes
Emergency	1 minute

Showing Telegraf Data

Making InfluxDB Dashboards

To show Telegraf data in InfluxDB:

Go to Dashboards in InfluxDB
Click "New" then "New Dashboard"
On the empty dashboard, click "+ Add visualization"
Pick "-- Grafana --" as the data source
Choose "Live Measurements" for query type
Select "stream/custom_stream_id/cpu" for Channel
Save your changes

This sets up your dashboard to show real-time CPU data from Telegraf.

Adjusting Data Views

To improve your data views:

Use InfluxDB query explorer to change InfluxQL queries
Change hostname settings to match your setup
Set time ranges to show the data you need
Use different chart types for different metrics

To change a query for a specific host:

Click "Edit" on the panel title
In "queries", change the host setting
The panel will now show data for that host

Tips for Clear Data Display

To show Telegraf data clearly:

Put related metrics together
Use colors to show important levels
Set changing levels based on past data
Add notes for big events or changes

Metric	Best Chart Type
CPU Use	Line graph or gauge
Memory	Area chart
Disk I/O	Bar chart
Network	Line graph with multiple lines

Fixing Problems and Improving Speed

Typical Issues and Fixes

When using Telegraf, you might run into these common problems:

Issue	Fix
High CPU or memory use	Lower how often Telegraf collects data
Slow data processing	Increase `metric_batch_size` to handle more data at once
Connection errors	Check if InfluxDB is running on the right port (usually 8086)

Making Telegraf Run Better

To help Telegraf work well:

Choose input plugins carefully
Use processors and aggregators to shrink data
Set up output plugins to send data efficiently
Limit how much of your computer Telegraf can use

Growing Your Telegraf Setup

As you need to watch more things:

Use more than one Telegraf instance
Pick the right setup:

Setup	What It Is	Best For
One config file	Many plugins in one file	Small to medium setups
Many computers	Telegraf on different servers	Big, spread-out systems
Many processes	Multiple Telegraf instances from same config	Lots of data, saves money

Keep an eye on how Telegraf itself is doing
