  - getDefaultZkHost
```
public String getDefaultZkHost()
```
    This method returns the default "zkHost" value for this node -- either read from the system properties, or from the "extra" properties configured explicitly on the SolrDispatchFilter; or null if not specified.
    This is the value that would have been used when attempting to locate the solr.xml in ZooKeeper (regardless of whether the file was actually loaded from ZK or from local disk)
    (This value should only be used for "accounting" purposes to track where the node config came from if it was loaded from zk -- ie: to check if the chroot has already been applied. It may be different from the "zkHost" configured in the "cloud" section of the solr.xml, which should be used for all zk connections made by this node to participate in the cluster)
    
    See Also:
    
    isFromZookeeper(), getCloudConfig(), CloudConfig.getZkHost()
  - getAllowPaths
```
public Set<Path> getAllowPaths()
```

```
public List<String> getAllowUrls()
```
    Allow-list of Solr nodes URLs.
  - hideStackTraces
```
public boolean hideStackTraces()
```
  - getModules
```
public String getModules()
```
    Returns the modules as configured in solr.xml. Comma separated list. May be null if not defined
  - getHiddenSysProps
```
public Set<String> getHiddenSysProps()
```
    Returns the list of hidden system properties. The list values are regex expressions
