| Attribute | Site24x7 Agent-based Monitoring | Site24x7 Agentless Monitoring |
|---|---|---|
| Methodology | Install Site24x7's server monitoring agent on every server. | Install Site24x7's On-Premise Poller on the server's network. |
| How it works | The agent collects data by executing commands and scripts directly in each server's operating system. | The On-Premise Poller connects to servers and collects data using SNMP or WMI. Note: Every server must enable SNMP or WMI protocol to communicate with the On-Premise Poller. |
| Installation methods |
1. Install a Site24x7 server agent individually on every server.
2. Bulk installation methods for Windows and Linux are available. |
Install the On-Premise Poller on your server network and add an individual server IP address/hostname or by specifying the IP range. |
| Connectivity to the internet | Access to the internet is not mandatory for all servers. Agents in the intranet servers can send the data to Site24x7 through a proxy server connected to the internet. | Outbound access to the internet for the On-Premise Poller is sufficient to collect server metrics. |
| Data transfer to Site24x7 | A one-way HTTPS connection that sends data to Site24x7 using the secure SSL protocol. | The On-Premise Poller uses an HTTPS connection to send data to Site24x7. |
| Credentials | Does not require credentials. | Requires SNMP or WMI credentials. Supported versions: SNMPv1/v2 and SNMP v3. |
| Dedicated server | Does not require a dedicated server for Site24x7. | Requires one dedicated server machine for running the On-Premise Poller. We support a maximum of 500 servers per Poller. |
| Log management | For log management, use the AppLogs agent to access the logs in the local server. | Cannot access the application logs without an agent. |
| Status checks and real-time alerting | Performs one-minute status checks to provide near real-time notifications. | Performs one-minute status checks and has a poll frequency of five minutes to collect the performance metrics. |
| Supported OS types | Windows, Linux, macOS, and FreeBSD. | Any server that supports SNMP or WMI protocol can add the agentless server. |
