# targetsCount defines the number of nodeexporter instances to scrape by every benchmark pod.
# This option allows to configure the number of active time series to push to remoteStorages.
# Every nodeexporter exposes around 1230 unique metrics, so when targetsCount
# is set to 1000, then the benchmark generates around 1230*1000=1.23M active time series.
# See also writeReplicas and writeURLReplicas options.
# targetsCount: 2000

# scrapeInterval defines how frequently to scrape nodeexporter targets.
# This option allows to configure data ingestion rate per every remoteStorages.
# For example, if the benchmark generates 1.23M active time series and scrapeInterval
# is set to 10s, then the data ingestion rate equals to 1.23M/10s = 123K samples/sec.
# See also writeReplicas and writeURLReplicas options.
scrapeInterval: 15s

# scrapeConfigUpdatePercent is the percent of nodeexporter targets
# which are updated with unique label on every scrape config update
# (see scrapeConfigUpdateInterval).
# This option allows tuning time series churn rate.
# For example, if scrapeConfigUpdatePercent is set to 1 for targetsCount=1000,
# then around 10 targets gets updated labels on every scrape config update.
# This generates around 1230*10=12300 new time series every scrapeConfigUpdateInterval.
scrapeConfigUpdatePercent: 1

# scrapeConfigUpdateInterval specifies how frequently to update labels
# across scrapeConfigUpdatePercent nodeexporter targets.
# This option allows tuning time series churn rate.
# For example, if scrapeConfigUpdateInterval is set to 10m for targetsCount=1000
# and scrapeConfigUpdatePercent=1, then around 10 targets gets updated labels every 10 minutes.
# This generates around 1230*10=12300 new time series every 10 minutes.

# writeConcurrency is an optional number of concurrent tcp connections
# for sending the scraped metrics to remoteStorage.writeURL.
# Increase this value if there is a high network latency between prometheus-benchmark
# components and remoteStorage.wirteURL.
# If this value isn't set, then the number of concurrent connections
# for sending the scraped metrics is determined automatically.
writeConcurrency: 1

# writeReplicas is an optional number of pod writers to run.
# Each replica scrapes targetsCount targets and has
# its own extra `replica` label attached to time series stored to remote storage.
# This option is useful for scaling the writers horizontally.
# See also writeURLReplicas option.
