Read values in scheduled script store in ftp

[admin]

Like this:

Code:

tagname = 'log'
logtime = os.time() - 60 * 60

query = [[
SELECT ol.*, o.name, o.datatype
FROM objectlog ol
JOIN objects o ON ol.address=o.id
JOIN objecttags t ON o.id=t.object
WHERE t.tag=? AND logtime>=?
ORDER BY id DESC
]]

buffer = { '"date","name","value"' }

items = db:getall(query, tagname, logtime)
for _, item in ipairs(items) do
  id = tonumber(item.address) or 0
  logdate = os.date('%Y.%m.%d %H:%M:%S', math.floor(item.logtime))
  etype = item.eventtype

  if (etype == 'write' or etype == 'response') and item.datatype then
    value = grp.decodevalue(item.datahex, item.datatype)
  else
    value = ''
  end

  buffer[ #buffer + 1 ] = string.format('%q,%q,%q',
    logdate, item.name or '', tostring(value))
end

csv = table.concat(buffer, '\n')
