Method Detail

munge

public static String munge(String s)

Munge a metric name so that it is suitable for use in a filesystem (ganglia stores metric names and host names in the file system but does not munge them well itself). In particular, any non-word characters (other than '.', '-' and similar things which are legal in file names) are converted to an underscore character ("_"). This gets rid of all punctuation characters and whitespace in the metric name itself, but will not translate unicode characters.

Parameters:

s - The name of the scale-out index.

Returns:

A string suitable for inclusion in a filename.

getFQName

public static String getFQName(String groupName,
               String localName)

Combines the group name and the local name to obtain the fully qualified metric name. Both names are munged before they are combined.

Note: Munging is required because we receive counters from other ganglia services and those counters must obey the rules for file systems, so we have to munge everything.

Parameters:

groupName - The group name (optional).

localName - The local name (required).

Returns:

The fully qualified, munged name.
