Learn about OVHcloud Monitoring and how to configure it for your Dedicated Servers.
The monitoring service allows OVHcloud to monitor the status of your machine and automatically trigger the intervention of a technician in the datacenter.
All the servers of our customers and the entire network are monitored 24/7 by OVHcloud technical teams.
OVHcloud intervenes as soon as an alert (non-response to the pings) is triggered in order to minimize the downtime of the servers and the network.
To implement a restrictive firewall, especially on ICMP, and continue to benefit from OVHcloud monitoring, it is necessary to authorize the IPs that you will find below.
Requirements
- An OVHcloud service on which you have installed a firewall
- Access to the firewall rules
OVHcloud Control Panel Access
- Direct link: Dedicated Servers
-
Navigation path:
Bare Metal Cloud>Dedicated servers> Select your server
Instructions
IP addresses to authorize
To implement a restrictive firewall without losing the benefit of OVHcloud Monitoring, it is necessary to whitelist the following IPs:
| Reverse | IP | Protocol |
|---|---|---|
| netmon-vin-probe | 51.81.92.16/29 | icmp |
| netmon-hil-probe | 147.135.33.104/29 | icmp |
| netmon-icmp-vin-2.monitoring.us.ovhcloud.com |
51.81.92.18 15.204.167.92 (both are required at this time) |
icmp |
| netmon-icmp-hil-2.monitoring.us.ovhcloud.com |
147.135.33.106 15.204.48.129 (both are required at this time) |
icmp |
| a2.ovh.net | 213.186.33.62 | icmp |
| ping.ovh.net | 213.186.33.13 | icmp |
Communication between the Real-Time Monitoring service and your server also requires that you allow inbound and outbound connections on UDP ports 6100 through 6200.
Server monitoring
You can set the monitoring status for a dedicated server from the General information tab.
In the Service status panel, click Disable interventions.
You can choose from the available options:
- Disabled: Your server is not monitored. It can receive ICMP (Internet Control Message Protocol) requests, but the monitoring will ignore their results if there is no response, and you will not receive any alerts from OVHcloud if the connection to the public network is lost.
- Enabled with proactive intervention: Your server is monitored (ICMP ping test). You will receive alerts sent to the email address linked to your technical contact's ID. You have authorized OVHcloud to resolve issues on your machine when there is an ICMP ping unavailable alert. A support ticket is automatically created, so you can follow up with your ticket.
- Enabled without proactive intervention: Your server is monitored (ICMP ping test). You will receive alerts sent to the email address linked to your technical contact's ID. Without proactive intervention enabled, OVHcloud will not resolve issues on your machine when there is an ICMP unavailable ping alert.
NOTE: Regardless of the monitoring option you select, certain failed operations may automatically trigger intervention from the data center team. These operations include, but are not limited to:
- Failed OS installations using OVHcloud templates (including diagnostics and potential hardware replacement, e.g., faulty disks),
- Failure to boot into rescue mode via the OVHcloud Control Panel, and
- Failed reboot attempts initiated from the OVHcloud Control Panel.
