PrometheusMetric

tenable.exporter.scrape.duration

API scrape duration

Dimensions:None

Technical Annotations (41)

Configuration Parameters (17)

query.startOffsetrecommended: 0

Starting offset for pagination

query.endOffsetrecommended: 2000-10000

Page size for export requests; controls memory usage and system load

num_assetsrecommended: 50-5000 (default: 50)

Higher values reduce API calls; lower values reduce per-chunk payload size

scrapeTimeoutrecommended: 30s

For high-cardinality or slow endpoints

intervalrecommended: 60s

Longer interval to reduce load on slow targets

sampleLimitrecommended: 50000

Drop scrape if more than 50k series to limit response size

scrape_timeoutrecommended: >10s, exceeding expected walk duration

Prometheus config to allow slow SNMP scrapes to complete

scrape_intervalrecommended: 60s in example

must be greater than scrape_timeout

max-repetitionsrecommended: 10

SNMP bulk request size affecting response time vs request count tradeoff

service.telemetry.logs.levelrecommended: debug

enables detailed logging to see timeout patterns

service.telemetry.logs.encodingrecommended: json

structured format for parsing timeout errors

exporters.otlp.timeoutrecommended: 60s

set to p99 backend processing time + 50% buffer

exporters.otlp.sending_queue.num_consumersrecommended: 20

increase consumers for parallel exports

processors.batch.send_batch_sizerecommended: 4096

reduce batch size to lower per-request processing time

processors.batch.timeoutrecommended: 10s

reduce batch timeout to send smaller batches more frequently

exporters.otlp.retry_on_failure.initial_intervalrecommended: 1s

start retry with short delay

exporters.otlp.retry_on_failure.max_elapsed_timerecommended: 300s

give up after 5 minutes total
