One of the first pieces of misinformation that vendors attempt to employ during negotiations is that an agentless solution will produce far less network bandwidth and congestion. Here’s why that isn’t necessarily the case:
Agents can employ intelligent data caching and spooling to send up less data than an agentless solution would. The agent can send up data when the status changes or differences only. Reports are batched up and sent up at random intervals, which means that the load on the network is minimized.
Agentless servers create data requests centrally to remotes devices, which then reply with data. This bi-directional chatter will generally consume far more network bandwidth.
