New elastickv-pebble-internals.json covering block cache hit rate, capacity, L0 pressure, compactions, memtables, FSM apply sync mode, and store write conflicts. Uses $datasource template variable and $node_id query variable driven by elastickv_pebble_l0_num_files.
Adds 'Unsupported Commands by Name' timeseries panel driven by the PR #594 elastickv_redis_unsupported_commands_total counter, and updates the 'Errors by Command' panel description so operators know the legacy 'unknown' bucket is broken down by real name in the new panel. The old panel is preserved to keep existing alerts wired up.
Merges the 9 panels from elastickv-redis-hotpath.json into a collapsed 'Hot Path (legacy PR #560)' row at the bottom of elastickv-redis-summary.json, preserving every panel verbatim, and retitles the summary to 'Elastickv Redis' now that it is the main Redis dashboard. Adds a $job template variable so the nested panels keep working. Deletes the standalone hotpath dashboard and updates the four source comments and the docs page that referenced it by path.
elastickv-cluster-summary was a pure DynamoDB-metric dashboard despite its title, so rename the file to elastickv-dynamodb.json, retitle it to 'Elastickv DynamoDB' with uid elastickv-dynamodb, and drop the misleading 'summary' tag. This also doubles as the dedicated DynamoDB dashboard requested in the refactor. Retitle elastickv-cluster-overview.json from 'Elastickv Cluster Overview' to 'Elastickv Cluster' now that it is the sole cluster landing page. No panel content changed. Update README to list the new file set and point each dashboard at its intended operator task.

This panel queries elastickv_redis_unsupported_commands_total, but that metric is not exported anywhere in the current tree (checked with repo search in monitoring/*.go), so the new chart will show no data in production until another change lands. Because the panel is presented as the breakdown for the unknown error bucket, shipping it before instrumentation is available creates a misleading observability gap for Redis incident triage.
Useful? React with 👍 / 👎.

The new Pebble internals dashboard depends on elastickv_pebble_fsm_apply_sync_mode, but this metric is not defined/exported in the repository’s monitoring code (again verified by searching monitoring/*.go), so this stat panel will always render empty for this commit. That leaves an always-dead panel in a core operator dashboard and can be mistaken for scrape/config failures rather than a not-yet-implemented metric.
Useful? React with 👍 / 👎.
Codex flagged that the "Unsupported Commands by Name" (Redis summary) and "FSM Apply Sync Mode" (Pebble internals) panels query metrics not yet on main, so during an incident operators could mistake the empty panels for a scrape failure. Append a sentence to each panel's description calling out the dependency and that the panel will populate automatically once PR #594 / PR #592 merge.

Thanks @codex for the P2 sequencing catch on the two forward-looking panels. Rather than pull them out (and then re-add once #594 / #592 merge), I annotated each panel description so on-call won't mistake an empty graph for a scrape failure:
Once the dependent PRs merge, the panels activate automatically — no further dashboard change needed. JSON validated with Commit: 43fe41b /gemini review |
