What are the differences between Agent-less vs Agent-Based Discovery?
- What are the advantages and disadvantages of the Universal Discovery (UD) Agent-less vs Agent-Based Discovery?
Universal Discovery (UD) allows customers to choose the best method of discovery per the specific needs and constraints of each management zone.
- Agent-less Discovery has the following advantages:
â¢ No need to deploy/maintain agent per server
â¢ No continued presence on discovered device (minimal footprint)
â¢ Leverages available access points (protocols) to get desired information
Note*: Not always Operating system credentials are available. Often security policies force credentials to be changed on a regular basis. Also, protocols like NTCMD require a lot of prerequisites (specific system configuration)
- Agent-based Discovery has the following advantages:
â¢ Overcome security barriers
â¢ Maintenance of user credentials is challenging
â¢ Deeper insight into computer information (e.g. software utilization)
â¢ Enables agent-initiated data reporting (âCall Homeâ)
Note*: Not everything can be done via the agent. The agent can only act as a replacement/alternative to shell protocols. So only those discovery jobs that work through shell protocols can potentially run through the agent.
