[GRA/BHS][Identity, Security & Operations] - Logs Data Platform maintenance notification

Scheduled for Sep 16, 10:30 - 19:30 UTC

Scheduled

As part of maintenance for the Logs Data Platform, we will replace the certificates for your Data-gathering tools on 16 September 2026, as the current intermediate certificate expires on 20 September 2026.

Start time : 16/09/2026 10:30 UTC
End time : 16/09/2026 19:30 UTC
Service impact : Customers who send their logs directly to the clusters are not affected by this maintenance and can disregard the rest of this message (Customer's log ingestion endpoint looks like gra1.logs.ovh.com:12202, no action is required).
However, customers who use an endpoint such as gra1-65d66a0a68728d746bbebbab.gra1.logs.ovh.com:6514 are affected by this maintenance and we recommend them to follow the relevant action plan below.

Case 1 — The customer's log forwarder agent performs no certificate verification
Customers who keep this behavior will not be impacted by the maintenance. No action is required.

Case 2 — The customer's log forwarder agent validates only the intermediate chain
1. Import the new certificate chain (as soon as possible). The new chain (self-signed, valid for 10 years) is already available in the OVHcloud Manager, on the home page of the customer's Logs Data Platform service. Customers should import it into their configuration before 16 September 2026.
2. Keep the old chain in place temporarily. Until 16 September 2026, customers should leave the old chain in their configuration so the agent accepts both chains (old + new) during the transition window, avoiding any surprise.
3. After 16 September 2026, once the maintenance is complete, customers should remove the old chain and keep only the new one (valid for 10 years).

Case 3 — The customer's log forwarder agent validates the intermediate + Data-gathering-tool certificate chain
1. Create a new Data-gathering tool in the Logs Data Platform project, replicating the exact configuration of the previous one.
2. Import the full certificate chain (intermediate + new self-signed certificate). Customers should go to the Data-gathering tools page, then open the "Useful information" section to obtain it.
3. Update the log forwarder agent configuration to push logs to this new Data-gathering tool.
4. Delete the old Data-gathering tool.
Service improvement : This maintenance renews the certificate chain that secures your log ingestion, ensuring uninterrupted and secure log delivery. The new chain is self-signed and valid for 10 years.

Thank you for your understanding.
