I think it is not possible to have ints in parsed JSON, so we can remove this case. Let's also add a warning though if we hit the default case:

log.Printf("E! [parsers.json] Unrecognized type %T", value)

for _, name := range p.TagKeys {
//switch any fields in tagkeys into tags
if fields[name] != nil {
switch fields[name].(type) {

To avoid needing to type assert in each case, you can do this:

switch value := fields[name].(type) {

Then in each case the value will already be in the type of the case label.

func (p *JSONParser) switchFieldToTag(tags map[string]string, fields map[string]interface{}) (map[string]string, map[string]interface{}) {
for _, name := range p.TagKeys {
//switch any fields in tagkeys into tags
if fields[name] != nil {

Nitpick, instead of nesting the switch statement in this check, I would check and continue:

if fields[name] == nil {
    continue
}

switch ....

This help with readability because the scope of the conditional is reduced.

I would remove this comment

Remove any commented out code

Instead of logging the values, use require to assert that the values are as expected.

if err != nil {
return nil, err
}

metric, err := metric.New(p.MetricName, tags, f.Fields, time.Now().UTC())
tags, nFields := p.switchFieldToTag(tags, f.Fields)

Now that we are adjusting the values after flattening, is it still required to keep the loop above on line 47?
