Changes since v1.43.0
-
FEATURE: automatically add missing label filters to binary operands as described at https://utcc.utoronto.ca/~cks/space/blog/sysadmin/PrometheusLabelNonOptimization . This should improve performance for queries with missing label filters in binary operands. For example, the following query should work faster now, because it shouldn't fetch and discard time series for
node_filesystem_files_free
metric without matching labels for the left side of the expression:node_filesystem_files{ host="$host", mountpoint="/" } - node_filesystem_files_free
-
FEATURE: vmagent: add Docker Swarm service discovery (aka dockerswarm_sd_config). See #656
-
FEATURE: add ability to export data in CSV format. See these docs for details.
-
FEATURE: vmagent: add
-promscrape.suppressDuplicateScrapeTargetErrors
command-line flag for suppressingduplicate scrape target
errors. See #651 and https://victoriametrics.github.io/vmagent.html#troubleshooting . -
FEATURE: vmagent: show original labels before relabeling is applied on
duplicate scrape target
errors. This should simplify debugging for incorrect relabeling. See #651 -
FEATURE: vmagent:
/targets
page now accepts optionalshow_original_labels=1
query arg for displaying original labels for each target before relabeling is applied. This should simplify debugging for target relabeling configs. See #651 -
FEATURE: add
-finalMergeDelay
command-line flag for configuring the delay before final merge for per-month partitions. The final merge is started after no new data is ingested into per-month partition during-finalMergeDelay
. -
FEATURE: add
vm_rows_added_to_storage_total
metric, which shows the total number of rows added to storage since app start. Thesum(rate(vm_rows_added_to_storage_total))
can be smaller thansum(rate(vm_rows_inserted_total))
if certain metrics are dropped due to relabeling. Thesum(rate(vm_rows_added_to_storage_total))
can be bigger thansum(rate(vm_rows_inserted_total))
if replication is enabled. -
FEATURE: keep metric name after applying MetricsQL functions, which don't change time series meaning. The list of such functions:
keep_last_value
keep_next_value
interpolate
running_min
running_max
running_avg
range_min
range_max
range_avg
range_first
range_last
range_quantile
smooth_exponential
ceil
floor
round
clamp_min
clamp_max
max_over_time
min_over_time
avg_over_time
quantile_over_time
mode_over_time
geomean_over_time
holt_winters
predict_linear
See #674
-
BUGFIX: properly handle stale time series after K8S deployment. Previously such time series could be double-counted. See #748
-
BUGFIX: return a single time series at max from
absent()
function like Prometheus does. -
BUGFIX: vmalert: accept days, weeks and years in
for:
part of config like Prometheus does. See #817 -
BUGFIX: fix
mode_over_time(m[d])
calculations. Previously the function could return incorrect results.
