Auto-provisioning
Auto provisioning is a feature that allows you to automatically apply a configuration file to a collection agent as soon as it comes online. This feature is useful when you want to apply a default configuration file to a collection agent as soon as it comes online.
Get started with auto-provisioning by simply creating a rule that will apply a configuration file to an agent that matches the rule.
The following example will apply a default Telegraf configuration file to any agent that has the tag "env:non-prod,os:centos_7,agent:telegraf,os:linux".
Pre-requisites:
- Passport
- If you don't already have a Passport account, create a free account now.
- An observability solution that can send alerts to Passport via a webhook.
- If you don't already have an observability solution, create a free account with Circonus now.
- A configuration file uploaded to Passport.
- If you don't already have a configuration file uploaded, upload a configuration file to your Passport account now.
Create a rule
Select a configuration file from Configurations list view page, then click the Rules tab and select Create Rule.
Now, create a rule that will apply the configuration file to the agents that matches the rule and then click create.
For example, create a rule that will apply the configuration file to all agents that have the tags "env:non-prod,os:centos_7,agent:telegraf,os:linux" as seen below.
Now, this configuration will automatically be applied to any agent that has the tag "env:non-prod,os:centos_7,agent:telegraf,os:linux" that is currently being managed and any new agent that comes online with the tag "env:non-prod,os:centos_7,agent:telegraf,os:linux".
Rule weights
A configuration can have 1 or more rules applied to it. When auto provisioning agents, set the rule weight to 1 so it will be the default configuration.
Doing this will allow you to have multiple rules applied to a configuration file and or agent with either lower or higher weights for other conditions such as auto-provisioning default configs, in coming alerts, Etc. When the rules with higher value weights expire, then the rules engine will apply the rule with lower weights to the agents.
We will set the weight of this rule to be something low such as 1 so we can default to this configuration file from other higher weighted configurations once they expire.
