Dashboard error

[shizunge]

Blocky version 0.25
Dashboard version: 57b1bdb

3 panels showed bad_data

• Avg response time
• Cache hit/miss rate
• Prefetch count

(Actually the dashboard had the same problem with blocky 0.24 too.)

[shizunge]

Also Denylist by group does not look correct.

blocky_denylist_cache should be blocky_denylist_cache_entries in v0.25

HI here
what is see compared to 0.24, the following panels are KO , i looked in details in formula
i was able to fix the others panels but 4 of them seems problematic, see below

• average resp time is KO -->"blocky_request_duration_ms_sum" and "blocky_request_duration_ms_count" are not working
• cache hit/miss ratio--->"blocky_cache_hit_count" and "blocky_cache_miss_count" are not working
• -prefetch hit ratio---> "blocky_prefetch_hit_count" and "blocky_cache_hit_count" are not working
• request duration (upstream)---> blocky_request_duration_ms_bucket

can you pleaseadvice on new items names if renamed in 0.25 compared to 0.24

try to fix stuff using this list here : https://0xerr0r.github.io/blocky/latest/prometheus_grafana/
but not sure how to mirror

• blocky_request_duration_ms_bucket
• blocky_request_duration_ms_sum
• blocky_request_duration_ms_count
• blocky_cache_hit_count
• blocky_cache_miss_count

@niouniou49 based on the screenshot, it seems it is an old version dashboard. The panel orders are different.

The latest in the repo seems designed to work with both old and new metrics. But there are bugs in some query expressions.

I see No data in some panels with 0.25 and a398516

• blocky_prefetchs_total should be blocky_prefetches_total
• blocky_prefetch_hit_count should be blocky_prefetch_hits_total
• blocky_cache_hit_count should be blocky_cache_hits_total
• blocky_cache_miss_count should be blocky_cache_misses_total
• blocky_request_duration_ms_bucket should be blocky_request_duration_seconds_bucket

[niouniou49]

all good now thanks @shizunge

This issue is not fixed, because the dashboard in the main branch does not work with v0.25.

Additionally if you want the dashboard to work for both 0.24 and 0.25, it needs extra effort.

@shizunge just updated queries, thanks for your hints. I think, support for 0.24 is not necessary, since working version can be checked out for 0.24 tag.
