Storage Data Path

/opt/adm/vmstorage/data

Storage minimum free disk space (bytes)

Minimum amount of free disk space (bytes), that must remain available in the file system containing the VictoriaMetrics Storage data directory

10737418240

Storage memory allowed (bytes)

Maximum amount of memory (bytes) which VictoriaMetrics Storage is allowed to use for internal cache and buffers

1073741824

Add key,value

In this field, you can define additional parameters that are not displayed in ADCM UI, but are valid for the VictoriaMetrics Storage component.

Each key/value pair specified in this field is converted into a command-line argument in the -key=value format and added to the Docker container startup command

 — 

Query Timeout

Maximum time allowed for executing a query on VictoriaMetrics Select component. Queries exceeding this limit are canceled.

Format the value using ms (milliseconds), s (seconds), m (minutes), or h (hours). Example: 1ms

30s

Maximum Concurrent Queries

Maximum number of queries that can be executed concurrently by the VictoriaMetrics Select component. Queries exceeding this limit are queued for up to Maximum Queue Duration and rejected with an error if not processed during this period

16

Maximum Queue Duration

Maximum time a query can wait in the queue when the Maximum Concurrent Queries limit is reached. Any query not processed during this period is rejected.

Format the value using ms (milliseconds), s (seconds), m (minutes), or h (hours). Example: 1ms

10s

Maximum Samples Per Query

Maximum number of raw samples a single query can process. Queries exceeding this limit are rejected.

Increase for wide time ranges or high-resolution data

1000000000

Maximum Series in Response

Maximum number of time series returned by the /api/v1/series endpoint. Protects against excessively large responses.

Set to 0 to disable the limit

30000

Maximum Unique Time Series Per Query

Maximum number of unique time series a single query can select from VictoriaMetrics Storage. Set to 0 to disable the limit

300000

Disable Query Cache

Disables the VictoriaMetrics Select in-memory query results cache. When enabled, every query fetches fresh data from VictoriaMetrics Storage

false

Cache Data Path

Path inside the container for persistent query cache storage. Requires a writable volume mounted at this path. If not set, cache is kept in memory only and lost on container restart

/cache

Add key,value

In this field, you can define additional parameters that are not displayed in ADCM UI, but are valid for the VictoriaMetrics Select component.

Each key/value pair specified in this field is converted into a command-line argument in the -key=value format and added to the Docker container startup command

 — 

Maximum Concurrent Inserts

Maximum number of insert requests that can be processed concurrently by the VictoriaMetrics Insert component. Requests exceeding this limit are queued for up to Maximum Insert Queue Duration and rejected with an error if not processed during this period

16

Maximum Insert Queue Duration

Maximum time a query can wait in the queue when the Maximum Concurrent Inserts limit is reached. Any query not processed during this period is rejected.

Format the value using ms (milliseconds), s (seconds), m (minutes), or h (hours). Example: 1ms

1m

Maximum Insert Request Size

Maximum size of a single Prometheus remote_write API request. Larger requests are rejected.

Format the value using KB, MB, GB, KiB, MiB, GiB. Example: 32MiB

32MiB

Maximum Labels Per Time Series

Maximum number of labels allowed for a single time series. Series with more labels are ignored, incrementing vm_rows_ignored_total{reason="too_many_labels"}

40

Maximum Label Name Length

Maximum length of a label name in accepted time series (bytes).

Series with longer label names are ignored

256

Maximum Label Value Length

Maximum length of a label value in accepted time series (bytes). Series with longer label values are ignored, incrementing the vm_rows_ignored_total{reason="too_long_label_value"} value

16384

Add key,value
