Known issues and maintenance¶
This guide covers package versions 0.1.6 and 0.1.7. Complete unfiltered scans for 0.1.7 on 17 October 2026 at 16:59 UTC retain 104 Critical and 680 High raw host matches on kernel identities and zero High/Critical matches in the runtime inventory, with no ignored findings. The retained diagnostic rescan for 0.1.6 has the same High/Critical counts. These are scanner matches, not distinct proven exploitable vulnerabilities. Runtime inventory results do not certify a clean host or absence of unreported vulnerabilities. The full local security gate has not passed.
The current supported stable Ubuntu AWS kernel does not yet provide all required corrections. The Ubuntu tracker still records a pending correction for CVE-2026-74446 at the 17 October 16:31 UTC check. Preserve this maintenance limitation when assessing the image for your environment; successful application tests or Marketplace review do not certify a clean host. Updates require a new verified image and a protected migration.
Package 0.1.7 includes the customer launch, access and hands-on instructions under /opt/sushi/docs/README.md and /opt/sushi/docs/DEMO.md. The local service was checked by importing and independently rereading three timestamped samples, then verifying the same data after a real instance reboot without importing again. Single-instance persistence is not high availability or a backup.
4. Protect state and plan upgrades¶
Application state is under /var/lib/victoriametrics; server configuration and private identity are under /etc/victoriametrics. Preserve those together with /home/ubuntu/.config/sushi/victoriametrics and any customer input/output directories. Treat backups containing credentials, documents, audio, metrics or repositories as private data. A single local EBS volume is not a redundant service or a backup.
For a consistent backup, finish active requests, stop the owning services below and take an encrypted EBS snapshot or protected file backup using your approved procedure. Preserve ownership and permissions. Start the same services afterwards and verify readback. Test restoration on a separate instance before replacing the original.
sudo systemctl stop victoriametrics.service sushi-victoriametrics-api.service
# Take and verify your protected backup while the services are stopped.
sudo systemctl start victoriametrics.service sushi-victoriametrics-api.service
A new Marketplace version does not update an existing instance. Launch the replacement separately, check state-format compatibility, restore only required customer state and verify your own read/write workflow before cutover. Keep a protected backup until the replacement is confirmed. Never erase a server identity as a routine upgrade step.
The generated self-signed TLS certificate expires after 365 days. Arrange an operator-reviewed certificate replacement before expiry, updating the client trust from the authenticated instance. Public DNS and certificate renewal automation are not included.
5. Diagnose a problem¶
sudo systemctl show victoriametrics.service sushi-victoriametrics-api.service -p ActiveState -p SubState -p NRestarts
sudo journalctl -u victoriametrics.service -u sushi-victoriametrics-api.service --no-pager -n 50
Inspect logs privately. Before sharing a support case, remove credentials, private hostnames and all customer content; include the Marketplace version, failing operation and a small invented reproduction. For connection errors, verify the correct Region/instance, Session Manager permissions, network endpoints and the active forwarding session. For input errors, check the package limits and request schema first. Do not install arbitrary replacement packages or delete customer state to force a retry.
Use the Software Sushi support contact and terms on the purchased Marketplace offer. VictoriaMetrics single-node documentation explains the upstream project; it is not a support commitment from that project for this package.
