Whether this host can produce a usable crash dump, and whether it recently did.

Topic id: crash_dump_config.

This topic is still rolling out. Endpoints on the general release do not send it yet.

Conditions

A condition is a state that holds for a while. The agent opens it when the host enters it, keeps it open while it lasts, and closes it when the host comes back out, so one episode answers for the whole stretch instead of one alert per sample.

ConditionSeverityHow an episode ends
recurring crash dumps (os_bsod_recurring)Minor to CriticalIt closes on a recovery rule written for this condition, which reads more than one measurement together.
page file too small for the dump (os_dump_pagefile_too_small)NoticeIt closes when the measurement falls back past its recovery point.

Occurrences

An occurrence is a thing that happened and was discovered, rather than a state that holds. It is announced once and has no closing event.

OccurrenceWhat it means
os_crash_dump_newnew crash dump

Inventory (every 8 hours)

SparkLogs: CONTEXT, Info, crash_dump_config: INVENTORY: dump posture.

Selected conditions

os_bsod_recurring

The host is bugchecking repeatedly.

Impact: Repeated bugchecks can interrupt users and services and require crash-dump analysis.

Example

started; bugchecks in five days 5 (threshold 5)

sparklogs.data.crash_dump_config.bsod_count_1d: 2
sparklogs.data.crash_dump_config.bsod_count_5d: 5
sparklogs.data.crash_dump_config.bsod_count_10d: 5

SparkLogs: os_bsod_recurring, Severe, crash_dump_config: os_bsod_recurring: NOTABLE: started; bugchecks in five days 5 (threshold 5)

os_dump_pagefile_too_small

The page file is too small for the configured crash dump.

Impact: A future bugcheck may fail to write the expected dump.

Example

started; page file short of the dump 50% (threshold 10%)

sparklogs.data.crash_dump_config.pagefile_shortfall_pct: 50.0

SparkLogs: os_dump_pagefile_too_small, Notice, crash_dump_config: os_dump_pagefile_too_small: NOTABLE: started; page file short of the dump 50% (threshold 10%)

os_crash_dump_new

A new crash dump appeared.

Impact: The host recently bugchecked.

Example

crash dump written. dump="071726-11250-01.dmp" written="2026-07-17T07 00 00Z" size_bytes="291456".

SparkLogs: os_crash_dump_new, Warning, crash_dump_config: os_crash_dump_new: NOTABLE: crash dump written. dump="071726-11250-01.dmp" written="2026-07-17T07 00 00Z" size_bytes="291456".
