VizBolt for Splunk: Predictive Alerts for Tableau Cloud
VizBolt for Splunk delivers Predictive Alerts for Tableau Cloud: fifteen detection signals that run inside your own Splunk on the Activity Log and warn on trajectories — refresh suspensions, queue congestion, storage exhaustion — with dates. Tableau alerts you at the wall; we alert you on the trajectory.
Sound familiar?
- A refresh schedule Tableau suspended silently, discovered weeks later when a number looked wrong
- The storage email that arrived at the limit with no cause and no lead time
- The 06:00 jobs that finish a little later every week
- A sign-in failure spike nobody saw until the lockout tickets
- “Our support tier doesn't include proactive monitoring.”
Alerts that cite their measurements
Real product messages, exactly as they arrive — the number, the trend, the date, and what to do before it.
VB-03Queue congestion
Jobs scheduled at 06:00 waited TP95 33.1 min in the last 24h against a 15-min target. Growing 0.5 min/day — reaches the 60-minute ceiling in about 49 days. Spread this window before then.
VB-15Storage exhaustion prediction
Site storage at 79.9%, climbing 0.21%/day — crosses quota around Oct 4. 33 days of warning; Tableau's own email arrives at the threshold.
VB-11Adoption drop
'Risk Heatmap' (owner: ops.admin) averaged 41 views/day over three weeks; last 7 days: zero. Total abandonment, not a dip — check for a broken extract or moved workbook.

Common questions
Do we need Splunk?
Yes — Splunk Enterprise or Splunk Cloud, with the Tableau Cloud Activity Log landing in it. Not on Splunk? Ask about the roadmap.
How do alerts reach us?
Email, Slack, or Teams, carrying the full plain-English story — and they also appear in Splunk's own Triggered Alerts.
Can we change thresholds?
Every threshold. They live in one editable lookup file with per-site overrides, and changes need no restart.
What about Tableau Server?
VizBolt for Splunk is for Tableau Cloud today. On Tableau Server, the Environment Review covers you now — and Server alerting is on the roadmap. Tell us if you need it.
What does Tableau alert on natively?
A storage email at the threshold. Annual reviews and native alerting are limited to the highest support tiers — VizBolt is the independent path for everyone.
Alerts fail silent, never loud: an alert with nothing proven to say says nothing.
