Cube Cloud allows exporting logs to third-party services, which allows users to leverage their existing log management tools. Cube Cloud uses Vector under the hood, which supports a wide range of destinations. To make use of Log Export, customers define a Vector sink configuration file and commit it to their repository.
In the example below, we'll set up Cube Cloud to forward logs to a hosted Loki instance on Grafana Cloud.
To enable log export, first go to the deployment's settings page and turn it on:
Only environment variables prefixed with
CUBE_CLOUD_LOG_EXPORT_ can be used in
First, go to your deployment's environment variables, then add the
authentication credentials for the Grafana Cloud-hosted Loki instance. We can
define as many environment variables as we need, but we must prefix them with
CUBE_CLOUD_LOG_EXPORT_ so that we can use them in our Vector configuration
Now, enter Development Mode and add a file called
vector.toml to your Cube
project. Open the newly-created file, and then add any relevant sink
configuration. We'll also want to use the environment variables we defined
[sinks.loki] type = "loki" inputs = [ "cubejs-server", "redis", "refresh-scheduler", "ext-db" ] endpoint = "https://logs-prod-us-central1.grafana.net" [sinks.loki.encoding] codec = "json" [sinks.loki.labels] app = "cube-cloud" env = "production" [sinks.loki.auth] strategy = "basic" user = "$CUBE_CLOUD_LOG_EXPORT_LOKI_USER" password = "$CUBE_CLOUD_LOG_EXPORT_LOKI_PASS" [sinks.loki_cubestore] type = "loki" inputs = [ "cubestore" ] endpoint = "https://logs-prod-us-central1.grafana.net" [sinks.loki_cubestore.encoding] codec = "json" [sinks.loki_cubestore.labels] app = "cube-store" env = "production" [sinks.loki_cubestore.auth] strategy = "basic" user = "$CUBE_CLOUD_LOG_EXPORT_LOKI_USER" password = "$CUBE_CLOUD_LOG_EXPORT_LOKI_PASS" [sinks.loki_cubestore.cubestore] levels = [ "trace", "info", "debug", "error" ]
Once done, save the file and commit it to your repository. Once you're back on the Overview page, you should now see a new "Log Export" resource:
Valid values for
cubestore input supports a
levels property, which allows filtering logs
by type. Valid values are:
levels is not specified, then only logs of type
error will be
