Simple capture the metric

/exporter2perfdata --url=<exporter url > --action="<metric name>"

Capture metric and validate results

Metric Value > 3600 will cause a CRITICAL Alert Metric Value > 1800 will cause a WARNING Alert

./exporter2perfdata --url=<exporter url> --action="<metric name>" --compare-type="1" --warning="1800" --critical="3600"

Metric Value < 600 will cause a CRITICAL Alert Metric Value < 800 will cause a WARNING Alert

./exporter2perfdata --url=<exporter url> --action="<metric name>" --compare-type="2" --warning="800" --critical="600"
