The first migration job

hmmm it's a very long list 😅 do I include the entire thing?
I'm also trying to run all these migration scripts before I upgrade to 0.88. That's how it should be, correct? I shouldn't be trying to run 0.88 first?

That's how it should be, correct?
Yes, so your existing dashboards and alerts are migrated with sqlite migration
do I include the entire thing?
Yes, please write a simple script to prepare a map

So I tried putting all of the metrics into 
NOT_FOUND_METRICS_MAP
e.g. 
ClickHouseErrorMetric_CANNOT_READ_FROM_FILE_DESCRIPTOR=ClickHouseErrorMetric_CANNOT_READ_FROM_FILE_DESCRIPTOR,ClickHouseErrorMetric_QUERY_IS_NOT_SUPPORTED_IN_MATERIALIZED_VIEW=ClickHouseErrorMetric_QUERY_IS_NOT_SUPPORTED_IN_MATERIALIZED_VIEW,ClickHouseErrorMetric_RECEIVED_ERROR_FROM_REMOTE_IO_SERVER=ClickHouseErrorMetric_RECEIVED_ERROR_FROM_REMOTE_IO_SERVER,chi_clickhouse_event_ThreadPoolReaderPageCacheMissElapsedMicroseconds=chi_clickhouse_event_ThreadPoolReaderPageCacheMissElapsedMicroseconds...
But it actually failed with this error now:
Copy code
exec /usr/local/bin/migrate: argument list too long
stream closed EOF for cluster-addon-signoz/signoz-data-migration-job-c4bnn (migration)
Ok, so ended up wiping all my metrics and trying everything from scratch. What ended up happening is that somewhere between helm chart upgrades, there used to be a 
signoz-otel-collector-metrics
that somehow ended up orphan and not tracked by ArgoCD, which was pushing all those metrics with the underscore
Deleted that deployment, wiped clickhouse again, re-did the migrations, and so far so good
