Luke

Luke
09/25/2024, 9:30 PMI have months of logs, almost 500GB, it would be a very bad day to lose them

Your data is not lost, just that with the new release if the above values are true the queries and ingestion is directed to the new table. For users having custom retention it’s recommended to run the setup with above config for the duration specified in retention setting before removing the flags. https://signoz.io/docs/operate/migration/upgrade-0.55

09/26/2024, 8:07 PMThanks, that has resolved it.
Luke
09/26/2024, 8:07 PMSome feedback though:
The migration documentation just says
Luke
09/26/2024, 8:08 PMI made an easy typo, I searched for docker-compose.yml (no a) and found frontend/docker-compose.yml, so that's what I modified
Luke
09/26/2024, 8:09 PMIf I search for .yaml I find 3 files, which do I modify?
Copy code
root@Signoz:/opt/signoz/signoz# find . -name docker-compose.yaml
./pkg/query-service/tests/test-deploy/docker-compose.yaml
./deploy/docker/clickhouse-setup/docker-compose.yaml
./deploy/docker-swarm/clickhouse-setup/docker-compose.yamlLuke
09/26/2024, 8:10 PMThe same is true of the other file
Luke
09/26/2024, 8:10 PM Copy code
root@Signoz:/opt/signoz/signoz# find . -name otel-collector-config.yaml
./pkg/query-service/tests/test-deploy/otel-collector-config.yaml
./deploy/docker/clickhouse-setup/otel-collector-config.yaml
./deploy/docker-swarm/clickhouse-setup/otel-collector-config.yamlLuke
09/26/2024, 8:11 PMI strongly suggest you update the document to specifically name the file users should modify, including the path because most users (including myself) do not understand the differences between these files and have no idea which to modify.
