Glean Incident Runbook

Overview

Incident response procedures for Glean enterprise search integration failures. Covers search degradation, connector sync failures, indexing backlogs, and permission sync drift. Glean aggregates knowledge across all company tools, so incidents impact employee productivity across the entire organization. When search breaks or returns stale results, teams lose access to critical institutional knowledge. Classify severity immediately and follow the matching playbook below.

Severity Levels

Level	Definition	Response Time	Example
P1 - Critical	Search fully down or returning zero results	15 min	All queries return empty, API 5xx errors
P2 - High	Connector sync failed, content going stale	30 min	Google Drive connector last synced 24h ago
P3 - Medium	Indexing backlog or partial result degradation	2 hours	New documents not appearing for 4+ hours
P4 - Low	Permission sync drift or single datasource issue	8 hours	One user sees docs they shouldn't access

Diagnostic Steps

# Test search API health
curl -s -o /dev/null -w "HTTP %{http_code}\n" \
  -H "Authorization: Bearer $GLEAN_API_TOKEN" \
  -H "Content-Type: application/json" \
  -X POST https://your-domain.glean.com/api/v1/search \
  -d '{"query": "test", "pageSize": 1}'

# Check datasource connector status
curl -s -H "Authorization: Bearer $GLEAN_API_TOKEN" \
  https://your-domain.glean.com/api/v1/getdatasourceconfig \
  -d '{"datasource": "DATASOURCE_NAME"}' | jq '.status'

# Verify indexing queue depth
curl -s -H "Authorization: Bearer $GLEAN_API_TOKEN" \
  https://your-domain.glean.com/api/index/v1/getstatus | jq '.statistics'

Incident Playbooks

API Outage

Confirm outage with diagnostic curl above and check Glean status page
Verify your Glean instance URL resolves and TLS cert is valid
Test from multiple networks to rule out local DNS or firewall issues
Notify users that search is temporarily unavailable
Contact Glean support with instance name, timestamps, and error codes

Authentication Failure

Verify API token is set: echo $GLEAN_API_TOKEN | wc -c
Check token expiry — Glean tokens may have a TTL configured by your admin
Test with a minimal search request (see diagnostics above)
If 401: regenerate token in Glean admin console under API settings
If 403: verify token scopes include search and indexing permissions

Data Sync Failure

Identify which connector failed via getdatasourceconfig for each source
Check connector credentials — OAuth tokens for Google/Slack/Confluence may have expired
Review connector error logs in Glean admin under Datasource Management
Re-authorize the connector if credentials expired
Trigger a manual re-crawl for the affected datasource
Monitor indexing status until backlog clears

Communication Template

**Incident**: Glean Search [Outage/Degradation]
**Status**: [Investigating/Identified/Mitigating/Resolved]
**Started**: YYYY-MM-DD HH:MM UTC
**Impact**: [Search unavailable / results stale since HH:MM / N datasources not syncing]
**Current action**: [Connector re-auth in progress / Glean support engaged / manual re-crawl running]
**Next update**: HH:MM UTC

Post-Incident

Document timeline from detection to resolution
Identify root cause (connector auth expiry / Glean platform issue / indexing bottleneck)
Audit all connector credentials for upcoming expirations
Verify permission sync is accurate post-recovery
Add alerting for connector sync age thresholds
Schedule review of datasource health dashboard weekly

Error Handling

Incident Type	Detection	Resolution
Search degradation	Empty results or low relevance scores	Check API health, verify index freshness
Connector sync failure	Stale content, `getdatasourceconfig` shows error	Re-authorize connector, trigger manual crawl
Indexing backlog	New docs not searchable after 4+ hours	Monitor queue depth, contact Glean if persistent
Permission sync drift	Users see restricted docs or miss accessible ones	Audit datasource permissions, trigger permission re-sync
