Construct customized observability options
Cisco Observability Platform (COP) permits builders to construct customized observability options to realize precious insights throughout their know-how and enterprise stack. Whereas storage and question of Metric, Occasion, Log, and Hint (MELT) knowledge is a key platform functionality, the Data Retailer (KS) permits options to outline and handle domain-specific enterprise knowledge. It is a key enabler of differentiated options. For instance, an answer might use Well being Guidelines and FMM entity modeling to detect community intrusions. Utilizing the Data Retailer, the answer might carry an idea comparable to “Investigation” to the platform, permitting its customers to create and handle the entire lifecycle of a community intrusion investigation from creation to remediation.
On this weblog put up we’ll train the nuts and bolts of including a information mannequin to a Cisco Observability Platform (COP) resolution, utilizing the instance of a community safety investigation. This weblog put up will make frequent use of the FSOC command to offer hands-on examples. In case you are not aware of FSOC, you possibly can evaluate its readme.
First, let’s rapidly evaluate the COP structure to grasp the place the Data Retailer suits in. The Data Retailer is the distributed “mind” of the platform. The information retailer is a complicated JSON doc retailer that helps solution-defined Varieties and cross-object references. Within the diagram beneath, the Data Retailer is proven “related” by arrows to different elements of the platform. It’s because all elements of the platform retailer their configurations within the information retailer. The Data Retailer has no ‘built-in’ Varieties for these elements. As an alternative, every element of the platform makes use of a system resolution to outline information varieties defining their very own configurations. On this sense, even inside elements of the platform are options that depend upon the Data Retailer. Because of this, the Data Retailer is probably the most important element of the platform that completely nothing else can perform with out.
So as to add a extra detailed understanding of the Data Retailer we will perceive it as a database that has layers. The SOLUTION layer is replicated globally throughout Cells. This makes the SOLUTION layer appropriate for comparatively small items of knowledge that must be shared globally. Any objects positioned inside an answer package deal have to be made out there to subscribers in all cells, subsequently they’re positioned within the replicated SOLUTION layer.
Get a step-by-step information
From this level we’ll swap to a hands-on mode and invite you to ‘git clone git@github.com:geoffhendrey/cop-examples.git’. After cloning the repo, check out https://github.com/geoffhendrey/cop-examples/blob/essential/instance/knowledge-store-investigation/README.md which provides an in depth step-by-step information on methods to outline a community intrusion Kind within the JSON retailer and methods to populate it with a set of default values for an investigation. Proven beneath is an instance of a malware investigation that may be saved within the information retailer.
The vital factor to grasp is that previous to the creation of the ‘investigation’ sort, which is taught within the git repo above, the platform had no idea of an investigation. Subsequently, information modeling is a foundational functionality, permitting options to increase the platform. As you possibly can see from the instance investigation beneath, an answer might carry the potential to report, examine, remediate, and shut a malware incident.
Should you cloned the git repo and adopted together with the README, you then already know the important thing factors taught by the ‘investigation’ instance:
- The information retailer is a JSON doc retailer
- An answer package deal can outline a Kind, which is akin to including a desk to a database
- A Kind should specify a JSON schema for its allowed content material
- A Kind should additionally specify which doc fields uniquely determine paperwork/objects within the retailer
- An answer might embrace objects, which can be of a Kind outlined within the resolution, or which had been outlined by some totally different resolution
- Objects included in a Resolution are replicated globally throughout all cells within the Cisco Observability Platform.
- An answer together with Varieties and Objects might be printed with the fsoc command line utility
Present worth and context on prime of MELT knowledge
Cisco Observability Platform permits resolution builders to carry highly effective, area particular information fashions to the platform. Data fashions permit options to offer worth and context on prime of MELT knowledge. This functionality is exclusive to COP. Search for future blogs the place we’ll discover methods to entry objects at runtime, utilizing fsoc, and the underlying REST APIs. We may also discover superior matters comparable to methods to generate information objects based mostly on workflows that may be triggered by platform well being guidelines, or triggers inside the information ingestion pipeline.
