Elasticbeats
Elasticbeat is a fantastic open source project part of the Elastic family. Beats are lightweight data shippers to capture all sorts of data such as logs, metrics or http responses.

LDAPbeat
Beats are lightweight data shippers to capture all sorts of data such as logs, metrics or http responses. A data repository I noticed was missing a beat was Active Directory/Directory services in general. As a result I created LDAPbeat, this beat lets you periodically query AD/any service that uses LDAP. This is super useful if you are measuring user activity or monitoring for any suspicious activity. Github link
