Architecture¶

Core Components¶

Backend Services¶

ObsAgent¶

The observability agent acts as a file reader that can be used with any text file containing messages which are the source events coming from the IT assets or business applications.

AIOpsCell¶

An AIOpsCell provides the following features:

Recognizes incoming messages from ObsAgents by regular expressions that describe the message and separator
Transforms incoming messages in structured instances events
Stores events in a database (persistent disk or in memory)

The AIOpsCell relies on a powerful queue messages technology that allows to manage big data context.

MetricsManager¶

This component is in charge of scheduling the queries defined by the administrator and update the raw data metrics.

TrendAnalysis¶

This service is in charge of continuously selecting the best trend algorythm by metric and metrics trend calculation.

CoreManager¶

This component is in charge of providing all APIs entry points to manage the Likpi application communication with third applications.

It is also in charge of the aggregation of the metrics by minute, hour, day, week, month and year.

Aggregator¶

It is in charge of the aggregation of the metrics by minute, hour, day, week, month and year.

Requesthandler¶

The Request Handler service allows the inter-communication between all Likpi components with persistent transactions. The transaction integrity and continuity is insured even when a service is stopped and later restarted.

NATs¶

The NATS Server acts as a central velocity system for the real time data streaming dedicated to the collection of metrics.

WebSocketGateway¶

The web socket gateway service is connected to the NATs server and provides real time data to the Likpi Web Portal console.

Postgresql Database¶

This database contains all Likpi configuration and metrics data.

HSQL database¶

This database is embeded with each AIOpsCell and stores the events coming from the ObsAgents. This database depending on your business needs and constraints can be configured on “In Memory” or “Persistent Disk” database.

Automator¶

The automation service allows to trigger any action script on behalf of the True Correlation component.

TrueCorrelation¶

This component checks continusly if a correlation scenario is matched and notifies SchedulerActivitie as requested.

SchedulerActivities¶

This service triggers actions to the Automation service if a scenario has been matched.

Likpi Web Portal Modules¶

Common Event Format¶

This module allows you to enrich the existing common event format fileds list. You will be able to cope with your specific business context and terminology if it’s needed.

Regex Builder¶

The Regex Builder is a powerful graphical tool to help the administrator to define by simple clicks the regex rules. After any modification on the Regex rules, they are taken in account in real time by the AIOpsCells.

Query Builder¶

The SQL Query Builder is a graphical tool that helos the administrator to easily create any query on events present in the collector’s databases or external sources. It’s the place where you build your Key Performance Indicators.

True Correlation¶

This module allows you to define simply and easily boolean scenarios on metrics and/or events activity for automation purpose.

Events Manager¶

This module provide you a view to quickly access the entire events present on your AIOpsCells. You can filter out with a graphical query builder and date time range your target events. You can also define custom events filters which suits you and make it available on the next login.

Groups & Users¶

This module allows you to manage your groups and associated users. With a group you can define access control list rules in order to associate specific dashboards, organizations and AIOpsCell. You have a tenant management feature thanks to these access control list rules.

Metric Attributes¶

With this module you can manage all your attributes metrics used by the SQL Query Builder module in order to get your KPIs which will be available for your real time dashboards.

Organisation¶

This form allows you to manage your organisation in order to provide tenant feature and segregation of data.

Activities¶

This form provides the ability to manage the definition of your script actions and your target automators’ servers. You can also send mails with users and/or groups.

Graphics¶

This form wizard will help you step by step to create graphs based on existing attribute metrics in order to make them available for your dashboards.

Dashboards¶

This module allows you to easily create real time dashboards composed with graphs. You can arrange your dashboard with some powerful drag & drop and resize features. You can also access to your data with date time range (real time, hourly, weekly, monthly, yearly or custom date time). You can also export graphs with different format like Excel.

Automation Guides¶

This wizard module allows you to define your automation policy based on a scenario correlation and activities.

Automation History¶

With this module you will be able to follow the entire automations history and related activities details.

ObsAgents¶

This form will provide you details on the entire observability agents status.

AIOpCells¶

This form will provide you details on the entire AIOpsCells status. You can also tag organizations by AIOpsCell for data segregation.

Automators¶

This form will provide you details on the entire automators status.

Connectors¶

This module allows you to define connectors to external databases which can be used on Query Builder.
