Hi all,
My solr version is release7.3.1, and I follow the solr 7.3.0 ref guide to
config ganglia
reporter in solr.xml as below:
<solr>
......
<metrics>
<reporter name="solrganglia" group="node,solr"
class="org.apache.solr.metrics.reporters.SolrGangliaReporter">
<str name="host">emr-header-1</str>
<int name="port">8649</int>
</reporter>
</metrics>
</solr>
than start solr service and encounted the execption like:
2018-07-11 17:47:31.246 ERROR (main) [ ] o.a.s.s.SolrDispatchFilter Could
not start Solr. Check solr/home property and the logs
2018-07-11 17:47:31.266 ERROR (main) [ ] o.a.s.c.SolrCore

Yes , I mean, why "org.acplt:oncrpc" dependency was excluded, and we need
package while
configurating ganglia reporter
<dependency>
<groupId>info.ganglia.gmetric4j</groupId>
<artifactId>gmetric4j</artifactId>
<version>1.0.7</version>
<exclusions>
<exclusion>
<groupId>org.acplt</groupId>
