# MPN latency metrics

# MPN latency metrics {#ariaid-title1}

Release version: Brazil  
Updated July 14, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read  
Monitor UE-to-switch latency and related KPIs across MPN-connected devices, with combined and per-KPI trend views, an instance summary table, and a last-recorded-value panel.

## Average Latency for All KPIs {#mpn-latency-dashboard__section_average_latency_all_kpis}

The Average Latency for All KPIs panel is a combined time-series chart showing all three latency KPIs together, in 30-second buckets. Filter the chart by Assurance ID, Instance, or DNN.
{#mpn-latency-dashboard__table_average_latency_all_kpis__entry__3}

| Title | Type | Description |
|-|-|-|
| Average Latency for All KPIs | Combined time-series chart | The average value of all three latency KPIs (`collector2ue`, `collector2sw`, `ue2sw`) over time, in 30-second buckets, filterable by Assurance ID, Instance, or DNN |
[Table 1. Average Latency for All KPIs]

{#mpn-latency-dashboard__table_average_latency_all_kpis}

## Per-KPI trend views {#mpn-latency-dashboard__section_per_kpi_views}

Three separate panels, one per latency KPI, each showing the trend in 2-minute buckets with legends by DNN and Instance.
{#mpn-latency-dashboard__table_per_kpi_views__entry__3}

| Title | Type | Description |
|-|-|-|
| Collector-to-UE latency | Time-series chart | Trend of the `collector2ue` KPI, in 2-minute buckets, with legends by DNN and Instance |
| Collector-to-switch latency | Time-series chart | Trend of the `collector2sw` KPI, in 2-minute buckets, with legends by DNN and Instance |
| UE-to-switch latency | Time-series chart | Trend of the derived `ue2sw` KPI, in 2-minute buckets, with legends by DNN and Instance |
[Table 2. Per-KPI trend views]

## Additional Info {#mpn-latency-dashboard__section_additional_info}

The Additional Info table lists latency data by instance, sorted by Instance.
{#mpn-latency-dashboard__table_additional_info__entry__2}

| Column | Description |
|-|-|
| Instance | The instance identifier |
| Customer | The customer associated with the instance |
| opCo | The operating company associated with the instance |
| Assurance ID | The assurance identifier for the instance |
| DNN | The data network name associated with the instance |
| Product | The product associated with the instance |
| Vendor | The vendor associated with the instance |
| Last value of Latency | The most recently recorded latency value for the instance |
| KPI | The latency KPI the row's value belongs to |
[Table 3. Additional Info columns]

{#mpn-latency-dashboard__table_additional_info}

## Instances with Latency (Last Recorded Value) {#mpn-latency-dashboard__section_last_recorded_value}

The Instances with Latency (Last Recorded Value) panel shows the most recently recorded latency value for each instance.

## Understanding data gaps {#mpn-latency-dashboard__section_data_gaps}

TSOM flags or logs a latency metric as stale when the latest published value for a CI is older than expected, rather than silently displaying it as current. If a switch-side record is missing for a DNN during a collection
cycle, the `ue2sw` calculation is skipped for that cycle. This may appear as a gap in the dashboard panels before rather than a repeated or estimated value.
