Detect bad and stale PI data
Find PI Points with stale values, bad latest value quality, missing data, undercompression signals, out-of-range values, or metadata rule violations.
The hidden PI System problem
Bad data often hides behind systems that look healthy.
Stale tags, bad values, broken AF attributes, failing analyses, and PI Vision displays with missing data sources can stay buried until they show up as wrong numbers, slow dashboards, or unreliable calculations.
PI Nexus+ gives administrators one place to find those issues, understand their impact, and trace them back to the PI Points, AF objects, analyses, and displays involved.
What needs attention right now?
PI Nexus+ helps answer the operational questions that usually take hours of manual investigation.

PI System Health Monitoring
Find the PI System problems that hide in plain sight.
PI Nexus+ scans across PI Data Archive, Asset Framework, AF Analyses, and PI Vision to surface stale data, bad values, broken references, unhealthy calculations, and display issues before they become operational noise.
See AF attribute health clearly
Review AF Attributes with value quality, data references, config strings, linked PI Points, dynamic limits, and health context in one searchable view.
Catch unhealthy AF analyses
Surface stopped, broken, or problematic AF Analyses with rule details, service load, inputs, outputs, owning elements, and template context.
Find broken PI Vision displays
Identify PI Vision displays that rely on missing, stale, or unhealthy data sources, with ownership and usage context for faster cleanup.
Trace what depends on what
Follow relationships between PI Points, AF Attributes, AF Analyses, AF Elements, templates, and PI Vision displays to understand impact quickly.
Turn scan results into action
Use health KPIs, issue lists, filtering, exports, suppression reasons, and object detail views to prioritize the problems that matter most.
Measurable Health Findings
A sample PI Nexus+ scan, by the numbers.
PI Nexus+ turns scan results into clear health findings across PI Points, AF Attributes, AF Analyses, PI Vision displays, and templates, so administrators can prioritize cleanup by severity and impact.
| Area | What PI Nexus+ Finds | Severity | Example Count |
|---|---|---|---|
| PI Points | Stale, bad, missing, or out-of-range values | High | 427 |
| AF Attributes | Broken references, bad values, and unhealthy linked tags | Critical | 86 |
| AF Analyses | Stopped, failed, or unhealthy calculations | High | 34 |
| PI Vision | Displays with missing or unhealthy data sources | High | 51 |
| AF Templates | Templates concentrating repeated downstream issues | Medium | 12 |
| Known Exceptions | Suppressed issues documented with reasons | Info | 143 |
Representative example only. Actual findings depend on system size, configured rules, scan targets, and data quality policies.

Product Tour
Follow health issues across your PI landscape.
PI Nexus+ connects inventory, health, issues, and dependencies so administrators can move from a warning to the affected PI Points, AF objects, analyses, and PI Vision displays without manual cross-checking.
01 / PI Point Health
Find stale, bad, and missing tag data faster.
Build a searchable PI Point inventory across Data Archives, evaluate latest value quality, and highlight stale, bad, missing, out-of-range, and rule-based issues.
What you can answer
- Which PI Points are unhealthy?
- Which tags have stale or bad latest values?
- Where is this tag used across AF, analyses, and PI Vision?
02 / AF Element & Attribute Health
Understand the AF context behind bad data.
Review AF Elements and Attributes with health context, linked PI Points, issue counts, derived template relationships, analyses, and dependency information in one place.
What you can answer
- Which AF objects are unhealthy?
- Which elements, attributes, and templates are affected?
- Which issues repeat across related AF structures?
03 / AF Analysis Health
Catch calculations that are stopped, failing, or unhealthy.
Surface problematic AF Analyses with rule details, service load, inputs, outputs, owning elements, and template relationships so calculation issues are easier to prioritize.
What you can answer
- Which analyses are stopped or unhealthy?
- Which inputs and outputs are involved?
- Which templates or elements concentrate analysis issues?
04 / PI Vision Impact
Find displays affected by missing or unhealthy data sources.
Inventory PI Vision displays, track ownership and access context, and identify dashboards that rely on stale, missing, or unhealthy PI Points and AF Attributes.
What you can answer
- Which displays are broken or at risk?
- Which data sources cannot be resolved?
- Who owns or uses the affected displays?
05 / Dependency Graph
Trace impact before cleanup, troubleshooting, or change.
Follow relationships between PI Points, AF Attributes, AF Analyses, AF Elements, templates, and PI Vision displays to understand what depends on what.
What you can answer
- Where is this tag or attribute used?
- What downstream objects depend on it?
- What will be affected if it changes?
