Fix failing Jira health checks
This recommendation is shown when Jira performance has degraded and we’ve detected failing health checks that can affect Jira’s index and search performance.
Signals used
Details of how we detect this issue.
Conditions
The following conditions need to occur together:
At least one key experience, such as viewing or editing an issue, shows degraded page load times (RFU).
JQL query performance is degraded, either in the RFU breakdown for pages (JQL taking longer as part of page load) or as global JQL query performance.
JQL query times or JQL slow query counts have been trending upward over the last month.
One or more indexing-related health checks are failing
How we detect it
Signal | Details |
|---|---|
RFU degradation | We look for Ready for User (RFU) degradation - cases where key Jira experiences take significantly longer than their historical baseline. This helps us confirm that users are actually experiencing slower page loads, not just one-off spike. |
RFU degradation (JQL execution time) | We use RFU degradation signals to detect when JQL execution time takes a substantial proportion of the page load and is slower than its historical baseline. |
Global JQL query degradation | We use JQL query execution time metrics to detect when overall JQL performance has degraded, independent of any single page. We compare current JQL execution times to historical values. |
JQL slow query events and trends | We track JQL slow query events and use trend analysis to see whether slow queries, or JQL execution times, have been increasing over the last month. An upward trend indicates that performance is getting worse over time, not just in a single spike. |
Health check failures related to indexing | We use health check failure events to detect when indexing-related health checks are failing in the same time window. |
Filters
When this issue occurs multiple times, we group occurrences under different time filters, for example a 24‑hour or 7‑day period. In this case:
For degraded experiences, we show the highest degradation from all occurrences in the selected time filter.
For failing health checks, we highlight which health checks were failing during those degraded windows, along with a percentage indicating how often each check was involved.
This helps you see whether JQL performance issues and health check failures are isolated events or recurring problems.
Frequency chart
The frequency chart shows how often this issue has occurred over time. This can help you identify patterns such as:
periods when JQL performance repeatedly degrades and coincides with the same failing health checks
whether fixing specific health checks reduces how often this recommendation appears
Recommended actions
Review and fix health checks related to indexing
Start by reviewing the list of failing health checks shown in the recommendation. These are the specific checks that were failing during the time window when JQL performance degraded.
Go to Jira administration > System > Troubleshooting and support > Health checks to see the current status, details, and suggested fixes for each failing check.
