Application Programming Interfaces (APIs)
There are several application programming interfaces, known as APIs, that are available for use with Falcon LogScale. Collectively, these are known as HTTP API. Everything you can do in LogScale's UI can be done through them. In fact, the UI is constructed using solely the public API.
Primary & Essential APIs
Below is a list of the primary and essential APIs available with Falcon LogScale. The headings are links to pages that will provide more information than the brief descriptions here.
Almost everything you might do with an application will require authetication. This is the first step. This API is used for doing that, for authenticating with LogScale.
This is the main endpoint for executing queries in LogScale. It streams results as soon as they're calculated. Depending on the query type filter or aggregate, the time of delivery changes.
Absolutely everything that can be done in LogScale can be done using GraphQL. It literally is the API that LogScale software uses internally. This section is extensive and growing.
Administrative APIs
These APIs are primarily for performing administrative tasks on LogScale.
If you're self-hosting LogScale and have set up your own cluster, this API may be used to manage your cluster.
With this API, you can redact individual events from a compressed segment files. It's intended to support removal of a small number of events from LogScale. Usually, this is used to remove personally identifiable information (e.g., a GDPR requirement), accidentally logged passwords or other confidential data from LogScale.
Server logs and other such data can be sent to LogScale and a repository using the Ingest API. That can be sent in a structured format, or it can be sent as it is, relying on LogScale parsers to add structure to it.
This API can be used to upload CSV or JSON files. These may then be used by the
match()functions.The health of LogScale can be determined by a set of individual health checks. This includes a Status API and a Health API.
In addition to LogScale's APIs, there are a few software libraries (click on the heading here for more) that can be used to integrate applications — written in other programming languages (e.g., JavaScript, Python) — into LogScale. Although they work, CrowdStrike doesn't offer support for them.
Attention
REST & GraphQL
LogScale has a mixture of GraphQL and REST endpoints. You can read about the motivation behind using GraphQL, as well as an introduction to GraphQL if you are not familiar with the technology.
Some of the REST endpoints described above are deprecated. We strongly encourage you to use the corresponding GraphQL queries and mutations instead. See the reference page on GraphQL for more information.
