Network requirements
Gateways have the following network connectivity requirements.
Outbound connectivity
| Port no. / Service | Gateway appliance | Windows gateway | Purpose |
|---|---|---|---|
| TCP port 443 / vProbe | Yes | Yes | Connect to the OpsRamp cloud platform using the public IP addresses. |
| DNS port 53 / DNS | Yes | Yes | To resolve address *.api.opsramp.com. |
| UDP port 123 / NTP | Yes | Yes | Network time protocol is used for clock synchronization using the public IP addresses. |
To find the NTP server public IPs, login to the gateway Web/Command-line interface and check the Date & Time section.
Inbound connectivity
| Port no. | Gateway appliance | Windows gateway | Purpose |
|---|---|---|---|
| TCP port 5480 | Yes | Access the gateway web-based admin UI for administration. | |
| TCP port 3128 | Yes | Accept connections from agents if agents are configured to connect to the cloud using the gateway embedded proxy. | |
| TCP port 162 | Yes | Yes | Send SNMP traps to the gateway from network devices. | TCP/UDP port 514 | Yes | Yes | Send syslog messages to the gateway from network devices. |
Server requirements
Gateway appliance
Capacity
| Number of managed resources | Required server capacity |
|---|---|
| Up to 25 resources | 2 CPU cores, 4 GB RAM / 40 GB Disk / 1 NIC |
| Up to 100 resources | 4 CPU cores, 8 GB RAM / 40 GB Disk / 1 NIC |
| Up to 500 resources | 8 CPU cores, 16 GB RAM / 60 GB Disk / 1 NIC |
| Greater than 500 resources at a single site | Deploy multiple gateways |
Note
We recommend you to have 8 GB RAM if you are going to configure the Gateway based SNMP discovery with multiple L2 and L3 protocols and / or with Seed based discovery.Capacity values are approximate and can vary depending on various factors, such as template frequency, resource type, network protocol, and the type of metrics.
Hypervisor
Gateway runs on the following hypervisors:
- VMware ESXi
- Citrix XenServer
- Microsoft Hyper-V
- Kernel Virtual Machine(KVM)
