Cookbook to install and configure telegraf
This was influenced by SimpleFinanace/chef-influxdb
Note: Some inputs will require other packages be installed and that is out of scope for this
cookbook. ie. [netstat] requires lsof
- CentOS 6.8 and 7.3
- Ubuntu 15.04 and 16.04
- Amazon Linux
- Windows 2012R2
- Mac OSX 10.12.x and 10.13.x
- Chef 12.5+
This cookbook can be used by including telegraf::default in your run list and settings attributes
as needed. Alternatively, you can use the custom resources directly.
| Key | Type | Description | Default |
|---|---|---|---|
| node['telegraf']['version'] | String | Version of telegraf to install, nil = latest | '0.10.0-1' |
| node['telegraf']['config_file_path'] | String | Location of the telgraf main config file | '/etc/telegraf/telegraf.conf' |
| node['telegraf']['config'] | Hash | Config variables to be written to the telegraf config | {'tags' => {},'agent' => {'interval' => '10s','round_interval' => true,'flush_interval' => '10s','flush_jitter' => '5s'} |
| node['telegraf']['outputs'] | Hash | telegraf outputs | {'influxdb' => {'urls' => ['http://localhost:8086'],'database' => 'telegraf','precision' => 's'}} |
| node['telegraf']['include_repository'] | [TrueClass, FalseClass] | Whether or not to pull in the InfluxDB repository to install from. | true |
| node['telegraf']['inputs'] | Hash | telegraf inputs | {'cpu' => {'percpu' => true,'totalcpu' => true,'drop' => ['cpu_time'],},'disk' => {},'io' => {},'mem' => {},'net' => {},'swap' => {},'system' => {}} |
| node['telegraf']['perf_counters'] | Hash | telegraf performance counters | {{ 'Processor' => { 'Instances' => ['*'] 'Counters' => ['% Idle Time','% Interrupt Time','% Privileged Time','% User Time','% Processor Time','% DPC Time',],'Measurement' => 'win_cpu','IncludeTotal' => true}} |
Installs telegraf and configures the service. Optionally specifies a version, otherwise the latest available is installed. The default installation type is package. For windows this defaults to chocolatey_package. If Chocolatey is not installed the resource will install this for you. Alternatively you can use the installation type file which will download and install the package.
telegraf_install 'default' do
install_version '0.10.0-1'
install_type 'package'
action :create
endWrites out the telegraf configuration file. Optionally includes outputs and inputs.
telegraf_config 'default' do
path node['telegraf']['config_file_path']
config node['telegraf']['config']
outputs node['telegraf']['outputs']
inputs node['telegraf']['inputs']
perf_counters node['telegraf']['perf_counters']
endWrites out telegraf outputs configuration file. You can call this several times to create multiple outputs config files.
telegraf_outputs 'default' do
outputs node['telegraf']['outputs']
endWrites out telegraf inputs configuration file.
telegraf_inputs 'default' do
inputs node['telegraf']['inputs']
endYou can call this several times to create multiple inputs config files. You'll need to specify different names for each telegraf_inputs resource, so they'll create separate config files.
For example, to add the nginx input:
node.default['telegraf']['nginx'] = {
'nginx' => {
'urls' => ['http://localhost/status']
}
}
telegraf_inputs 'nginx' do
inputs node['telegraf']['nginx']
service_name 'default'
reload true
rootonly false
endNote that there are three optional parameters for this resource that could've been left out in this case:
- service_name [default: 'default'] if you need to override which service should be restarted when the config changes;
- reload [default: true] whether to restart the service when the config changes;
- rootonly [default: false] whether to restrict access to the config file so it's not world readable;
Writes out telegraf performance counters configuration file for windows hosts only.
telegraf_perf_counters 'default' do
perf_counters node['telegraf']['perf_counters']
endYou can call this several times to create multiple performance counter config files. You'll need to specify different names for each telegraf_perf_counters resource, so they'll create separate config files.
For example, to add a network interface performance counter:
node.default['telegraf']['network_interface'] = {
'Network Interface' => {
'Instances' => ['*'],
'Counters' => [
"Bytes Received/sec",
"Bytes Sent/sec",
"Packets Received/sec",
"Packets Sent/sec",
],
'Measurement' => 'win_net',
},
}
telegraf_perf_counters 'network_interface' do
perf_counters node['telegraf']['network_interface']
service_name 'default'
reload true

Note that there are three optional parameters for this resource that could've been left out in this case:
- service_name [default: 'default'] if you need to override which service should be restarted when the config changes;
- reload [default: true] whether to restart the service when the config changes;
