Subject [jira] [Updated] (SOLR-9812) Implement a /admin/metrics API
Date Fri, 16 Dec 2016 12:39:58 GMT


Shalin Shekhar Mangar updated SOLR-9812:
    Attachment: SOLR-9812.patch

Patch which adds a new MetricsHandler

The /admin/metrics API supports the following parameters:
# group=all,jvm,jetty,node,core -- multiple group parameters can be specified and it also
accepts comma-separated values. (default is 'all')
# type=all,counter,gauge,histogram,meter,timer -- similar to the 'group' parameter, both multiple
'type' parameters as well as comma-separated values can be specified

> We added a bare bones metrics API in SOLR-9788 but due to limitations with the metrics
servlet supplied by the metrics library, it can show statistics from only one metric registry.
SOLR-4735 has added a hierarchy of metric registries and the /admin/metrics API should support
showing all of them as well as be able to filter metrics from a given registry name.
> In this issue we will implement the improved /admin/metrics API.
