I'm excited to announce one of the biggest releases of stagemonitor. It includes over 120 commits (with a increasing number contributed from the community) and helps you to get started with stagemonitor way faster! But that also means that there are a number of breaking changes.

Features

• Support for Elasticsearch as a time series database (TSDB) (see the Elasticsearch and the updated installation wiki page). This is now the primary and recommended TSDB for stagemonitor, deprecating graphite.
  • Stagemonitor provides Kibana 4 and Grafana 3 dashboards for elasticsearch
• Support for InfluxDB as a time series database (no prebuilt dashboards)
• Changed how exceptions on requests are found (see #116 thx @ryanrupp)
• You can now add custom properties to the request trace. For example you could track the number of results of a search and create a Kibana dashboard for that. Make sure to refresh the index metadata in Kibana so that you can see the new properties in the visualization composer. Code example:

final RequestTrace request = RequestMonitor.getRequest();
if (request != null) {
    request.addCustomProperty("search_hits", searchResult.getTotalResults());
}

• Add ability to only report certain requests to Elasticsearch (see config key stagemonitor.requestmonitor.onlyReportRequestsWithNameToElasticsearch)

Bug Fixes

• Fixed some issues in regard to thread safety (thx @marcust)
• Proper population of the username in the request trace (see #116 thx @ryanrupp)
• Fixed a thread leak (see #117 thx @ryanrupp)

Breaking changes

• The layout of the metric names in graphite has changed. The dashboards have been updated accordingly but you won't be able to see you old values in it.
• Removed RequestTrace.parameter: String in favour of RequestTrace.parameters: Map<String, String>. That way you can refer to a specific parameter in your custom dashboards.
• Captured IP addresses (ipv4 and ipv6) are now anonymized by default for privacy. This can be changed via the parameter stagemonitor.anonymizeIPs
• The default value of the config key stagemonitor.ehcache.get.timer has changed from true to false
• The configuration key stagemonitor.requestmonitor.requestTraceTTL does not exist anymore. Use stagemonitor.requestmonitor.deleteRequestTracesAfterDays instead. The new mechanism deletes a whole index instead of single documents wich is much more performant.
