munin-node: Error output from elasticsearch_docs:

I recently got the error several times in syslog:

munin-node: Error output from elasticsearch_docs:

I suspect it may be because server was under heavy load and the GET request failed. Under this circumstance shouldn't the script print "$name.value U" instead of an error message to comply with Munin expected format?

It's not a big deal except that I do monitor the syslog for unexpected errors which often times exposes real issues and this kind of error creates noise.

Thanks!
