Prerequisites for installing the On-Premise Poller
To monitor your internal network and resources behind a firewall, you need to install the On-Premise Poller within your network. You can install the
On-Premise Poller on physical or virtual machines.
The machine on which the On-Premise Poller will be installed should meet the below requirements:
RAM | 16GB (A minimum of 12GB of memory is required apart from the memory consumed by the OS and other processes) |
Processor/ Virtual Processor | 8 processors/ 16 Virtual Processors |
Processor Speed | 2.5GHz or above |
Disk Space | 250GB or higher |
OS | Windows or Linux Web Page Speed (Browser) monitoring is available only on CentOS 7.0-7.8 or RHEL 7.x (Requires additional software installation)Currently, the On-Premise Poller does not support ARM-based machines.

Table 1: System requirements for installing the On-Premise Poller.
The On-Premise Poller needs to be started with root or Administrator privileges after installation, depending on whether the machine OS is Linux or Windows.
If the On-Premise Poller is installed in a secure network, make sure you allow access to
these domains and ports in your firewall to facilitate communication with the Site24x7 central server.
The requirements for an On-Premise Poller might differ slightly according to the specific type of monitoring you require.
Additional requirements for network monitoring
We recommend using dedicated On-Premise Pollers to monitor your networks.
Ports to be allowlisted:
The following ports need to be included in the allowlist for both the network's firewall (if applicable) and the firewall of the machine hosting the On-Premise Poller:
Port | Protocol | | Inbound/ Outbound/Bidirectional | |
161 | UDP | SNMP commands and messages | Bidirectional | |
| UDP | | Inbound | |
8060 | TCP | Network module for data collection | Bidirectional | |
13306 | TCP | | - | |
| TCP | | Inbound | |
22 | SSH | SSHD port The default SSH service is used for remote login to the device on which the On-Premise Poller is installed. | Bidirectional | Network Configuration Manager (NCM) |
23 | Telnet | Telnet port The default Telnet service is used for remote login to the device on which the On-Premise Poller is installed. | Bidirectional | NCM |
69 | TFTP | | Bidirectional | NCM |
514 | UDP | | Inbound | NCM |
Table 2: Additional ports to be allowlisted.
If ports 8060, 9996, and 13306 are unavailable, subsequent ports that are free will be identified and used, like 8061, 9997, and 13307, respectively.
The number of On-Premise Pollers required to monitor your networks might vary based on the number of resources to be monitored. Use this
calculator to find out the number of On-Premise Pollers that you will require.
Additional requirements for Web Transaction (Browser) and Web Page Speed (Browser) monitoring
We recommend using dedicated On-Premise Pollers to monitor your Web Transaction (Browser) and Web Page Speed (Browser). You can monitor up to 40 Web Transaction (Browser) monitors at a five-minute poll interval using one On-Premise Poller with the system requirements mentioned above.
