You can iterate through all the cache entries to get information:

public string GetCacheEntriesInfo()
{
    var sb = new StringBuilder();
    // Get the existing cache entries from the RuleSession - this returns
    // a set of RuleApplicationReferences
    IEnumerable<RuleApplicationReference> cacheEntries;
    cacheEntries = RuleSession.RuleApplicationCache.Items;
    foreach (RuleApplicationReference cacheEntry in cacheEntries)
    {
        // Extract information from the rule application
        sb.AppendLine("Rule App Name:" + cacheEntry.GetRuleApplicationDef().Name);
        sb.AppendLine("Unique Name:" + cacheEntry.Name);

        // if it has been compiled, you can get properties such as time
        if (cacheEntry.LastMetadataCompile != null)
        {
            DateTime lastMetaCompileTime = cacheEntry.LastMetadataCompile.Value.UtcDateTime;
            sb.AppendLine("Last metadata compile:" + lastMetaCompileTime.ToString());
        }
        // get information about its rank in the cache
        sb.AppendLine("Cache retention rank:" + cacheEntry.CacheRetention.Weight.ToString());
        sb.AppendLine();
    }
    return sb.ToString();
}
