Creat logs in txt file
#1
Good day!
Can you help me with such question:
I need to create regular log files *txt type. Each day it will be a new file with a name like date. It is necessary to save it on any shared local net folder

thank you

Here is a part of my daily report script. It runs in a scheduled script every day at 00:00 and creates a csv file in /tmp folder for object logs of previous day.

PS: Credit for parts of the script goes to Edgars  Wink

Code:
-- Set logtime start-end and date to get past day data
date = os.date('*t')
date.hour=0
date.min=0
date.sec=0
log_end=os.time(date)-1
date.day = date.day - 1
log_start=os.time(date)


dates = {
 ['start'] = date,
 ['end'] = os.date('*t'),
}

-- Log filename
logfile=string.format('DailyLog_%s.csv', os.date('%d-%m-%Y',log_start))


-- list of objects by id
objects = {}

-- Select objects address and datatype
query = 'SELECT address, datatype, name FROM objects'
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'
query = 'SELECT * FROM objectlog WHERE logtime >='..log_start.. ' and logtime<=' .. log_end.. ' ORDER BY id'
for _, row in ipairs(db:getall(query)) 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('%d/%m/%Y %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

-- write file only when there's data in buffer
if #buffer > 1 then
result, err = io.writefile ('/tmp/'..logfile, table.concat(buffer, '\r\n'))
log('Created log file '..logfile)
end

-- error while writing
if err then
alert('File write error: %s', tostring(err))
end

Sorry, but it is necessary to create only txt files

You just need to change the extension to txt on logfile=string.format('DailyLog_%s.csv', os.date('%d-%m-%Y',log_start)) to 
logfile=string.format('DailyLog_%s.txt', os.date('%d-%m-%Y',log_start))
the structure although will be the same.

I "stole" this script (thank you). It runs perfect, but how can I access (download to PC) the CSV file produced?

I have tried Filezilla and can access the Wiser/SL successfully, but neither the user "ftp" nor the user "app" display anything that resembles "/tmp/......" which is the path used above in the following line: result, err = io.writefile ('/tmp/'..logfile, table.concat(buffer, '\r\n'))

Thanks in advance

FTP path is /home/ftp, just make sure that you have some algorithm to delete old files. Otherwise you can run out of free space at some point.

I'm still confused on this point. I used Filezilla to connect and placed a doorbell sound file (at what I'm taking from your post above is /home/ftp). My ftp login was user ftp (can choose from ftp or apps). But my Custom Javascript file appears not to see the copied file. For example, in the following file if I uncomment and use the mozilla file, the sound plays fine. But when written as shown here with the local file, the code does not work. Is it a linux permissions thing?

Code:
// the following function plays a sound when the doorbell is pressed (Object 0/250/72 is set true)
// FTP path is /home/ftp (use Filezilla to put sound file there)

$(function(){
   grp.listen('0/250/72', function(object) {
      if (object.value == true ) {
//        var audio = new Audio('https://interactive-examples.mdn.mozilla.net/media/examples/t-rex-roar.mp3');
        var audio = new Audio('/home/ftp/Doorbell.mp3');
        audio.play();
      }
   });
});

Can you help me?

Thanks!

See this thread: https://forum.logicmachine.net/showthrea...20#pid7920
You need to use apps ftp username and upload to user directory.

I am not able to find this file...
I log in with FileZilla with both "apps" and "ftp", but cannot find this folder. I have neihter the folder /home/ftp

In the script I log the err, result, and get true for result and nil for err.

The example script writes to /tmp/, which cannot be accessed via FTP. /home/ftp/ is the absolute path for writing from scripts. If you access FTP using ftp user then any file placed into /home/ftp/ will be visible in the base directory.
Code:
result, err = io.writefile('/home/ftp/' .. logfile, table.concat(buffer, '\r\n'))
