I have the performance signature working. However, once I added one graph for response time, now the edit button does not work. Basically not allowing me to add any additional graphs or even editing the graph on the PerSig page in Jenkins.
basically you can add more graphs by adding timeseriesIds to the specfile or by adding entries to the metrics parameter of the report pipeline step:
perfSigDynatraceReports envId: 'Dynatrace Demo Environment', metrics: [[metricId: 'ruxit.python.elasticsearch:active_primary_shards'], [metricId: 'ruxit.python.mysql:connection_errors_max_connections']], nonFunctionalFailure: 2
