Troubleshooting
Problem
My Service Diagnosis Metrics Search and Forecasting charts are empty although I continuously load data to Predictive Insights.
Symptom
In $PI_UI_HOME/wlp/usr/servers/piserver/logs/messages.log, I found these issues:
SystemOut O INFOThere are too many missing values within the data for this KPI to generate forecasts. The required data availability is at least 0.5
SystemOut O INFOForecast values could not be obtained
Cause
The topic’s system.aggregation.interval was set to 5 (minutes), but the data came every 15 minutes, so that means that data availability was only 33% and too low to produce the charts.
Resolving The Problem
1) You can run:
$PI_HOME/bin/admin.sh set -t=<topic name> system.aggregation.interval 15
2) Then logout of the UI and login again and try again. The UI should render the Metrics Search chart and the forecast.
