Cardinality Monitor

Monitor and analyze Prometheus metric cardinality to identify potential performance issues

Last updated: {{ report.summary.analysis_timestamp }}

{% if report.summary.health_status == 'healthy' %} Cardinality levels are healthy {% elif report.summary.health_status == 'warning' %} High cardinality detected {% else %} Critical cardinality levels detected {% endif %}

{% if report.summary.health_status == 'healthy' %} All metrics are within acceptable cardinality thresholds. {% elif report.summary.health_status == 'warning' %} Some metrics exceed warning thresholds. Monitor for performance impact. {% else %} Critical cardinality levels detected. Performance degradation is likely. {% endif %}
