[Security Solution] Indexing Time Column Not Populated For Any Rule Executions
Introduction
In the realm of security solutions, accurate and timely indexing of alerts is crucial for effective threat detection and response. However, a critical issue has been identified in the Rule Monitoring tab of the Detection Rules page, where the Indexing Time column fails to display any values, even when rules successfully generate alerts. This article delves into the details of this bug, its impact, and the steps to reproduce it.
Bug Description
The Indexing Time column in the Rule Monitoring tab of the Detection Rules page is not showing any values, regardless of whether the rule is in a Running or Succeeded state. This is a critical issue, as it hinders the ability to accurately measure the time spent indexing alerts during rule executions.

Kibana/Elasticsearch Stack Version
The Kibana/Elasticsearch stack version used in this environment is 9.1.0.
Version Details
VERSION: 9.1.0
BUILD: 86430
COMMIT: e576a625c1dab160e1a50f212a180d1b816ab7cd
Functional Area
The functional area affected by this issue is Detection Rules Monitoring.
Pre-requisites
To reproduce this issue, the following pre-requisites must be met:
- Have detection rules
- Detection rules generated alerts
Steps to Reproduce
To reproduce this issue, follow these steps:
- Go to Rules -> Rule Monitoring
- Observe the Indexing Time column
Current Behavior
The column displays a blank (i.e. no value) for all rule executions tested, even when alerts were successfully indexed.
Expected Behavior
The Indexing Time column should show the total time (in ms) spent indexing alerts during the last execution of the rule, as indicated by the tooltip.
Impact
The failure of the Indexing Time column to display values hinders the ability to accurately measure the time spent indexing alerts during rule executions. This can lead to:
- Inaccurate threat detection and response
- Delayed incident response
- Increased risk of security breaches
Conclusion
The Indexing Time column not being populated for any rule executions is a critical issue that affects the accuracy and timeliness of threat detection and response. To resolve this issue, it is essential to investigate and address the root cause of the problem. In the meantime, users are advised to use alternative methods to measure the time spent indexing alerts during rule executions.
Recommendations
To resolve this issue, the following recommendations are made:
- Investigate and address the root cause of the problem
- Implement a temporary workaround to measure the time spent indexing alerts during rule executions
- Update the Kibana/Elasticsearch stack to the latest version to ensure that the issue is resolved
Future Work
Future work will focus on:
- Resolving the root cause of the problem
- Implementing a permanent solution to measure the time spent indexing alerts during rule executions
- Updating the Kibana/Elasticsearch stack to the latest version to ensure that the issue is resolved
