My library Knowledge Sources To Go is very popular, but it was intended mainly as a thematically grouped guide to standard sources and was provided by me as a PDF file. For certain topics, however, there is so much content that I can no longer include it in that document, as it cannot continue to grow forever.
For this reason, I have decided to handle such topics in individual community articles like this one instead.
What is the Agent Client Collector?
The Agent Client Collector is a ServiceNow agent installed on your Windows, Linux, and macOS devices to monitor your company’s infrastructure and installed applications. It is is built on a Sensu framework and comes installed with monitoring capabilities for servers, databases, application servers, and middleware. It also enables you to adopt and extend monitoring with additional checks from the Sensu community, as well as with any Nagios-compatible plugins. Checks and policies run in the agent to retrieve the relevant data, which is transformed into events or metrics, as appropriate. Events and metrics are sent from the agent to ITOM Health in your ServiceNow instance through a pre-installed MID Server and stored in the relevant events or metrics database.

Extend ACC-V to parse a signature file, and create tags
The CMDB consumer want to check the owner team of a Server in the CMDB. For Cloud (AWS, Azure) environments, it is managed by tags, but in legacy Datacenters, we can parse a custom signature file that will be deployed on the servers. This article describes an example of implementation to discover this signature file using ACC-V agent, and how to script the update of the CMDB.
