I use the statistics server for this: it is less janky than reading the
statistics file and can be fetched remotely. The output from
http://server:8053/json/v1/server is about 10KB and usually has the info I
need, e.g. opcodes.QUERY, nsstats.QryTCP, nsstats.QryUDP, boot-time (for
detecting restarts).
