It says there is no
. SigNoz needs a cluster named
. It would be set up automatically unless you took different steps for setting up ClickHouse?
@Ragulraj It looks like you are using external ClickHouse helm chart and not that maintained by SigNoz. There are some pre-requisites for external clickhouse: • UDF script and histogram quantile binary needed in clickhouse: custom-function.xml and histogramQuantile binary • must have at least one zookeeper instance • distributed cluster named
set up required: clickhouse-cluster.xml • user passed must have enough privileges to create/manage databases in CH • secure connection not supported between clickhouse and signoz components yet
@Ashu including above in docs would be helpful for anyone using SigNoz with external clickhouse
Noted @Prashant Shahi. Should I create a new page for it here: https://signoz.io/docs/operate/clickhouse/ Or can it go under any of the already existing pages?
Yes, it makes sense for it to he under operate/clickhouse
