Hi all,
I am stumped trying to get statistics from the Solr server. It seems
that every time I get the correct SolrInfoMBean, when I look up the proper
value (by name) in the NamedList, I get the exact same number back each
time. For example, upon start-up the server reports that "2" queries have
been performed, and any time I pull the value out of the MBean after that it
says "2" even though the stats.jsp reports an increasing number of queries
over time. What am I doing wrong?
Here is my sample code:
public class SolrUtil {
protected static final CoreContainer coreContainer;
protected static final String DEFAULT_CORE_NAME = "";
static {
CoreContainer.Initializer initializer = new CoreContainer.Initializer();
try {
coreContainer = initializer.initialize();
}
catch (Exception e) {
throw new ExceptionInInitializerError("Can't initialize core
container: " + e.getMessage());
}
initialize();
}
private static SolrCore getCore() {
return getCore(DEFAULT_CORE_NAME);
}
private static SolrCore getCore(String name) {
try {
return coreContainer.getCore(name);
}
catch (Exception e) {
e.printStackTrace();
}
return null;
}
public static String getSolrInfoMBeanValue(SolrInfoMBean.Category
category, String entryName, String statName) {
Map<String, SolrInfoMBean> registry = getCore().getInfoRegistry();
for (Map.Entry<String, SolrInfoMBean> entry : registry.entrySet()) {
String key = entry.getKey();
SolrInfoMBean solrInfoMBean = entry.getValue();
if ((solrInfoMBean.getCategory() != category) ||
(!entryName.equals(key.trim()))) {
continue;
}
NamedList<?> nl = solrInfoMBean.getStatistics();
if ((nl != null) && (nl.size() > 0)) {
for (int i = 0; i < nl.size(); i++) {
if (nl.getName(i).equals(statName)) {
return nl.getVal(i).toString();
}
}
}
}
return null;
}
[...I have other methods, that also get the value as a long, etc....]
}
This code is modeled after the SolrDispatchFilter.java, _info.jsp and
stats.jsp.
I'd appreciate any help. (And yes, my core is named "".)
Sincerely,
Daryl.
