Discovery time PropertySource | Archive

Very simple PropertySource that outputs the epoch (in milliseconds) and a human-readable timestamp showing when the PropertySource ran - i.e. this will show the last time Auto Properties ran for any given collector-monitored resource. This will be true for regular collector-scheduled runs and manual / API triggered Active Discovery runs. v1.1.0: Y2P3HN Like any device properties, these could be used in dynamic group definitions and reporting. You could use the same approach to add instance-level properties to discovered instances of multi-instance DataSources (using scripted Active Discovery) to be able to see and report on (via a Device Inventory report) most recent successful discovery update times - and therefore also identify instances where discovery hasn't run successfully, or where persistent instances have ceased to respond and therefore haven't been rediscovered. It's so simple, I'll drop the groovy script in here directly: import groovy.time.TimeCategory; println 'auto.properties_discovered_human=' + new Date().format('yyyy-MM-dd HH:mm:ss'); println 'auto.properties_discovered_epoch=' + System.currentTimeMillis(); That's it. It'll look like this for a device:
