Rules API

Coralogix provides an activation/deactivation rules API for its Rules engine. This allows you to control your rules and trigger their activation remotely based on triggers such as alerts and usage warnings.

This guide will help you use our Rules CRUD-API to create, read, update or delete rules and rule groups using an API.

In order to send an external request, the request headers should contain the following:

Content-Type: application/JSON
Cache-Control: no-cache
Authorization: Bearer {an auto-generated API key, which can be found under Settings –> Account –> ‘API access’ and generate a new API key}

Each object in the array should contain the field for the matcher and the constraint. The field must be one of applicationName, subsystemName, or severity, and the constraint (string) that will be the value for the chosen field (if the field is severity, the value should be one: debug, verbose, info, warning, error, critical) E.g [ { "field":"applicationName", "constraint":"prod" }, { "field":"severity", "constraint":"info" } ]

NOTE When moving rules from one account to another keep in mind that the rules groups you imported are concatenated after the existing rules groups, we do not override existing groups by default. If you want to override the existing groups you should first remove them entirely and then import

In order to get the groupId so you could use it with the different requests’ URLs, enter your account settings –> Rules. Click on any group and the browser URL will show the groupId. The ruleId on the other hand can only be retrieved when executing a GET request to get a certain rule/group or when getting all the rules of the account.
