It has both local file and remote FTP options.
Hello Admin,
I have applied the solution from the example on the link, although unfortunately I just noticed that not all fields are included on the csv file. I would like to export all data that can be seen on the object logs utility. For the moment only timestamp, address, name and value is included in the csv export...
I am using the following script:
Code:
--ftp file
ftpfile = string.format('/home/ftp/%s.csv', os.date('%Y-%m-%d_%H-%M'))
-- get past 12 hours data (43200 seconds)
logtime = os.time() - 12 * 60 * 60
-- list of objects by id
objects = {}
-- objects with logging enabled
query = 'SELECT address, datatype, name FROM objects WHERE disablelog=0'
for _, object in ipairs(db:getall(query)) do
objects[ tonumber(object.address) ] = {
datatype = tonumber(object.datatype),
name = tostring(object.name or ''),
}
end
-- csv buffer
buffer = { '"date","address","name","value"' }
-- get object logs
query = 'SELECT src, address, datahex, logtime, eventtype FROM objectlog WHERE logtime >= ? ORDER BY id DESC'
for _, row in ipairs(db:getall(query, logtime)) do
object = objects[ tonumber(row.address) ]
-- found matching object and event type is group write
if object and row.eventtype == 'write' then
datatype = object.datatype
-- check that object datatype is set
if datatype then
-- decode data
data = knxdatatype.decode(row.datahex, datatype)
-- remove null chars from char/string datatype
if datatype == dt.char or datatype == dt.string then
data = data:gsub('%z+', '')
-- date to DD.MM.YYYY
elseif datatype == dt.date then
data = string.format('%.2d.%.2d.%.2d', data.day, data.month, data.year)
-- time to HH:MM:SS
elseif datatype == dt.time then
data = string.format('%.2d:%.2d:%.2d', data.hour, data.minute, data.second)
end
else
data = ''
end
-- format csv row
logdate = os.date('%Y.%m.%d %H:%M:%S', row.logtime)
csv = string.format('%q,%q,%q,%q', logdate, knxlib.decodega(row.address), object.name, tostring(data))
-- add to buffer
table.insert(buffer, csv)
end
end
-- upload to ftp only when there's data in buffer
if #buffer > 1 then
data = table.concat(buffer, '\r\n')
io.writefile(ftpfile, data)
end
How can this be modified to include the type (read/write) and source address fields?
Kind Regards,
